EDUCATIONAL
TECHNOLOGY
Unit
I – THE CONCEPT OF EDUCATIONAL TECHNOLOGY
INTRODUCTION
Educational Technology
is made up of two words, ‘education’ and ‘technology’.
The word ‘education’
has been derived from the Latin words ‘educare’,
‘educere’, ‘educo’ which means ‘to train’,
‘to instruct’, ‘to put’, ‘to draw out’ or
‘lead forth’. Thus education is an
act or process of acquiring and imparting knowledge, skills and attitudes.
The word ‘technology’
was derived from the Greek words ‘technic’
means art or skill and ‘logia’ means
‘science or study’. Thus technology means the science of study of an art or
skill.
According to the
International Dictionary on Education, technology is the application of
scientific knowledge to a practical purpose (problem).
MEANING
AND DEFINITIONS
Educational Technology is a
system in education in which machines, materials, media, means and methods
(5M’s) are interrelated and work together for the fulfillment of specific
educational objectives. A judicious use of these together with new functions
and roles of educational personnel can bring about more efficient and effective
teaching learning.
Educational Technology
is an applied or practical study which aims at maximizing educational effects
by controlling relevant factors such as educational purposes, educational
content, teaching materials, educational environment, conduct of students,
behaviour of instructors and interrelations between students and instructors.
The NCERT defines Educational Technology as
the means of development, application and evaluation of three different things;
i) techniques, ii) system and iii) aids to improve the process of human
learning.
S. S. Kulkarni (1968): Educational Technology
may be defined as the application of the laws as well as recent discoveries of
science and technology to the process of education.
G. O. M. Leith (1967):
Educational Technology is the systematic application of scientific knowledge
about teaching-learning and conditions of learning to improve the efficiency of
teaching and training.
Shiv K. Mitra (1968): Educational Technology can be conceived as a
science of techniques and methods by which educational goals could be realized.
I. K. Davies (1971): Educational
Technology is concerned with the problems of education and training context and
it is characterized by the disciplined and systematic approach to the
organization of resources for learning.
NEED
AND IMPORTANCE OF EDUCATIONAL TECHNOLOGY
The man is a biological
system. When he uses the external physical objects (television, radio, films,
etc.,), these objects are said to be the extended form of man. These objects
are also known as communication media. The teaching can be subjected to the scientific
analysis by educational technology with the use of communication media.
Coordination can be established between teaching and learning. Hence,
educational technology is frequently used in the areas of teaching and
learning. The need and importance of educational technology in teaching and
learning can be mentioned as follows:
Ø The
most important contribution of educational technology in the world of education
is providing scientific base to education.
Ø The
latest innovations in educational technology are very useful in solving the
problem related to the individual differences during teaching and learning.
Ø The
use of devices like radio, television, tape-recorder etc., could be possible
only due to educational technology. The pupils living in the far-off places are
able to enjoy their benefits, as a result of educational technology.
Ø The
solution of problems of educational management can seek help from the methods
as suggested by educational technology, e.g. system analysis.
Ø Number
of openings for conducting experiments related to problems of classroom teaching
and training could be possible.
Ø Educational
technology helps in understanding the structure of education and its nature.
Ø Educational
technology plays appreciable role in making the teaching and learning more
purposeful and effective.
Ø Educational
technology makes possible the maximum use of resources available in an institution.
Ø An
increase in teacher’s efficiency can be possible only due to educational
technology.
Ø Educational
technology helpful in bringing the expected behavioral changes in the pupils.
Ø In
educational technology, all levels are used, i.e. memory level, understanding
level and reflective level. While using these levels, the pupils move towards
originality and become creative.
Ø Educational
technology has proved much useful in learning outcome.
Ø Owing
to population explosion, more and more educational provisions can be made with
the help of educational technology, for example programmed learning,
corresponding education.
Ø Educational
technology is capable of contributing in the research work in the field of
education.
SCOPE
OF EDUCATIONAL TECHNOLOGY
The scope or areas of educational
technology is summarized as below;
Ø Analysis
of the Process of Teaching and Learning: Educational technology
tries to discuss the concept of teaching, process of teaching, variable of
teaching, phases and levels of teaching, theories of teaching, principles of
teaching, concept of learning, theories of learning, relationship between
teaching and learning, integration of theories and principles of teaching and
learning for attaining optimum educational purposes.
Ø Determination
of Educational Goals or Objectives: Educational technology
discuss the topics such as identification of educational needs and aspirations
of the community, suggesting broad educational objectives, analyzing the broad
objectives in terms of the specific classroom objectives of teaching and
learning, specifications of these objectives in behavioural terms.
Ø Development
of the Curriculum: This aspect of educational technology
is concerned with the designing of suitable curriculum for the achievement of
the stipulated objectives. It may describe the ways and means for the selection
of suitable learning experiences or contents, organization of these contents
and analyze the suitability of the curriculum in relation to objectives, means,
materials and evaluation.
Ø Development
of Teaching-Learning Material: This area of
educational technology is concerned with the production and development of the suitable
teaching-learning material in view of the objectives, curriculum and available
resources. Here it tries to discuss the essential techniques of developing
software and instructional material like programmed learning material, computer
assisted learning material, mass media instructional material, personalized
system of instruction and preparation of lesson plans.
Ø Teacher
Preparation or Teacher Training: Teacher is a key figure
in any process of teaching and learning. Educational technology, therefore,
takes care of the proper preparation of teachers for exercising their complex
responsibilities. For this purpose, educational technology includes topics like
models of teaching, micro-teaching, stimulated teaching, term-teaching, teacher
effectiveness, modification of teacher behaviour, classroom interaction and
interaction analysis.
Ø Development
and Selection of the Teaching-Learning Strategies:
This aspects deal with the central problem of teaching-learning act. Here educational
technology tries to describe the ways and means of discovering, selecting and
developing suitable strategies of teaching in terms of the optimum learning and
available teaching-learning resources, availability of different types of
teaching methods, devices and models of teaching along with their use for the
optimum results.
Ø Development,
Selection and Effective Utilization of the Appropriate Audio-Visual Aids and
Mass Media: Teaching- learning is greatly
influenced and benefited by the use of appropriate audio-visual aids. Educational
technology covers the aspects of various types of audio-visual aids, their
selection to a particular teaching-learning situation, their production and development
in view of the available resources, proper handling and maintenance, their
storage and retrieval and consideration about their cost-effectiveness and
effective utilization in education on the individual and collective basis.
Ø To
Work for the Effective Utilization of the Subsystem of Education:
Educational technology considers education as a system operating in a
systematic and scientific way, for the achievement of educational objectives.
So it includes the study of different sub systems, their operations and processes
in terms of input and output, the needed development in the working of the
subsystem in view in the economy, output and functionality of the system and
the organization and management of the system in an effective way by specifying
the respective roles of the man, machine and media in relation to the purposes
of teaching and learning.
Ø To
Provide Essential Feedback and Control through Evaluation:
Educational technology is essentially concerned with the task of exercising
appropriate control over the process of teaching and learning by planning and
devising suitable tools and devices for the continuation evaluation of the
process and product of the teaching learning activities. Such evaluation
provides an appropriate feedback to the learners as well as the teachers for
brining necessary improvement at the preparatory and implementation stages of
their specific acts. For this purpose, educational technology discusses the
ways and means of suitable evaluation techniques and their planning,
development, selection and appropriate use in relation to the objectives of
teaching-learning system.
Thus, educational
technology is concerned with all the variables, phases, levels and aspects of
the teaching-learning process. In brief, it works for the overall planning and
organization of thy system or sub-systems of education. It helps all those who
are connected directly or indirectly to the processes and products of
education. It teaches the teachers the art of teaching, the learner the science
of learning, the educational planners, the structure of planning and the administrators
or managers the skill of managing or administering the task of teaching and
learning. It works for the individualization of instructions as well as for
improving the group-dynamics of the classroom. It reaches to the individuals,
groups and the masses privileged or unprivileged through its media and
means.
TECHNOLOGY
IN EDUCATION AND TECHNOLOGY OF EDUCATION
The movement towards educational
technology began to develop after World War II. Educational technology is often
considered to be the intermix of two aspects:
Technology in Education and Technology of Education and is
diagrammatically represented as follows;

Technology
in Education
The term technology in
education refers to the use or application of technological advancement such as
various equipment, material and machines for educational purposes. It includes audio-visual
equipment, hardware and electronic devises like projectors, films, radio,
television, tape recorder, teaching machines, tele-text and computer aided
instructions for individualized and group learning.
Thus, technology in education
can provide its services for the following purposes:
Ø It
provides the needed appliances, equipment and audio-visual material and mass
media for the different purposes and functions of education.
Ø Enables
the teachers to handle and make optimum use of equipment.
Ø To
develop positive attitude towards these equipment.
Ø It
helps the individualized and group learning for achieving the goals of formal
or non-formal education.
Technology of Education
The term technology of
education signifies a system or technological approach to the problems of
education. It refers
to the application of behavioural sciences like psychology of educational theories
and practical teaching-learning problems, instruction and motivation etc. The
field technology of education focus on the development of teaching and learning
procedures borrowed from behavioural psychology. Emphasizing on this point of
view T. K. Robinson (1976) writes:

FORMS
OF EDUCATIONAL TECHNOLOGY
Educational technology,
in a broader sense stands for the application of the principles and techniques
of science and technology as well as psychology and pedagogy in the activities
of teaching and learning. As a result, it has been capable of providing
necessary ways and means, theoretical as well as practical, for improving the
processes and products of teaching-learning related to both formal and informal
education. With such a broad concept, educational technology has formed its
roots and wings in certain distinct aspects and forms in various courses and
programmes related to the study and application of educational technology. In
general, they can be listed as follows:
1. Teaching
Technology
2. Instructional
Technology
3. Behavioural
Technology
4. Instructional
Design Technology
Let us discuss these
forms of educational technology in detail.
TEACHING
TECHNOLOGY
Teaching technology, as
a form of educational technology is concerned with the task of systematization
of the process of teaching. Here, teaching cannot merely be treated as a sum
total of certain teaching skills. A teacher has to play the role of a
technician by learning the art and science of teaching. In this sense, teaching
is considered as a technology that a teacher should try to know and practice
well if he wishes to be successful in his teaching job
If a teacher can teach
well with the least efforts resulting into maximum productivity, then he can be
thought of utilizing teaching as a technology. The essence of the application
of technology lies in getting more and better output with the least input in
terms of time and labour. If a teacher knows the art and technique or if he is
in a position to make use of the teaching technology in realizing the teaching
objectives, he can get more success in his task with the least of efforts. The chief exponents of Teaching
Technology are I.K. Davies, N.L. Gagne,
Herbert, Hunt, Burner and Robert Glaser.
Fundamental
Principles and Characteristics of Teaching Technology
Teaching technology, as suggested by E. G. Vedanayagam (1988), can be distinguished because of certain characteristics and
fundamental principles as follows:
Ø Teaching
is a scientific process and its major components are content, communication and
feedback.
Ø There
is a close relationship between teaching and learning.
Ø It
is possible to modify, improve and develop the teaching-learning activities.
Ø The
terminal behaviour of the leaner can be established by appropriate teaching
environment.
Ø Teaching
skills can be developed and strengthened by means of feedback devices with or
without sophisticated techniques.
Ø Pre-determined
learning objectives can be achieved by designing suitable teaching activities.
Ø Use
of achievement motivation technique enhances the output of the teacher and the
learner.
Contents
of Teaching Technology
A
teacher has to imbibe the art and techniques of technology. Davies (1971), in his work Management of Learning, has presented
the contents of teaching technology in the shape of four steps. These steps
systematically prescribe the contents of teaching technology to be learnt by a
teacher for becoming a teaching technician and are as follows;
Planning of Teaching: Teaching
technology helps a teacher to plan the details of his teaching journey to be
travelled along with his students. For this purpose, a teacher must formulate
the teaching-learning objectives for the ongoing teaching-learning process and
then carefully plan for the realization of these set of objectives by taking
care of the (i) the entry behaviour of the learners (ii) selection of
appropriate learning experiences, (iii) selection of appropriate teaching
methods, strategies and aid materials and (iv) creating a conducive and helpful
environment for proper teaching-learning.
Organization of Teaching: In
its second step, teaching technology supplies the necessary knowledge and
skills to the concerned teacher for organizing all the available
teaching-learning resources, men and materials, for the realization of the set
objectives in the most effective and economical way. Specifically, it may talk
about the ways and means of seeking cooperation of the administrative
personnel, parents and community; developing teacher’s own competencies for
better communication including use of proper teaching methods, aids and
strategies.
Leading of Teaching: Teaching technology
in this step provide necessary knowledge and skills for a teacher to motivate,
encourage and guide and thus lead his students on the path of learning for the
realization of the teaching-learning objectives.
Controlling of Teaching: Teaching technology
in this step help a teacher to acquire necessary knowledge and skill for the
measurement and assessment of the teaching-learning outcomes in view of the set
teaching-learning objectives.
INSTRUCTIONAL
TECHNOLOGY
As
the name suggests, this kind of educational technology is meant for helping the
instructor and the learner in the process of imparting instruction for the
realization of the instructional objectives in a particular teaching-learning
situation, which is mostly cognitive in nature. The conative as well as
affective domains of the learner’s behaviour are almost neglected in the
services provided by instructional technology. In simple words, it is a type of
technology meant for brining improvement in the instructional process. Here the
term instruction stands for a certain type of command meant for getting some
specific information, knowledge and understating about a thing, system or
process. The type of technology which may help the learner and the instructor
in this task may be termed as instructional technology. The chief exponents of instructional
technology are B.F Skinner, Bruner, Glaser, Gilbert
and Mager.
Instructional
technology may be defined as a subsystem of educational technology which helps
the instructor or the learner himself as a part of his self-learning or auto
instruction by determining the media, methods and, materials for the
realization of the stipulated instructional objectives in a given
teaching-learning situation.
Let
us visualize how does instructional technology helps the instructor and the
learner in the task of instruction and learning in a particular
teaching-learning situation.
Setting
of Instructional Objectives
Instructional
objectives are the core and heart of any instructional process. Whatever piece
of instruction is planned, it needs setting of instructional objectives in the
beginning. What type of behavioural changes are expected after going through
that piece of instruction to the learner is thus to be decided and set before
proceeding. The following factors are also considered while framing the instructional
objectives,
Ø The
age and grade level of the learner
Ø The
physical, emotional, social and mental potential of the leaner
Ø The
previous experiences of the learner related to the subject and topic
Ø The
men, material resources available for imparting instruction
Ø Taxonomy
of instructional objectives (Bloom, Simpson, Harrow, Robert Mager’s Approach,
Robert Miller’s Approach or RCEM Approach)
Taking
Decision about the Instructional Material
In
the view of the instructional objectives, what type of learning experiences
should be provided to the learner needs to be decided at this stage. For this
purpose we have to select the teaching-learning experiences and then organize
and integrate them properly for utilizing in the course of instruction. This
instructional material is then provided by following the principles of simple
to complex, known to unknown, specific to general, theory to practice. For auto
instruction, like programmed learning, CAI, teaching machines, the
instructional material is well available in the form of well arranged,
sequenced from suiting the abilities, needs and requirements of the learners
for learning at their own pace.
Taking
decision about the Media and Methods
For
imparting instruction, one has to take proper decision about the selection of
particular media and method or a combination of media and methods depending
upon the nature of instruction and resources and environment available in a
particular teaching-learning situation.
It contains the topic like the following
in its prescribed syllabus of course:
Ø Instructional
strategies like lecture strategy, demonstration strategy, etc.
Ø Special
instructional procedures for carrying out auto-instructional or self-learning
like programmed instruction, instruction carried out with the help of teaching
machines, etc.
Ø Cooperative
or group instructional strategies like working on project, living and learning
in the community, etc.
Ø Knowledge
and application of various types of audio-visual aids and instructional
material such as radio, television, tape recorder, projector, charts, etc.
Taking
Decision about the Proper Instructional Environment
Particular type of
environment is essential for carrying out particular type of instruction, and
at then helps the teacher as well as learner for organization of that type of
instructional environment.
Helping
in the Task of Evaluation
Evaluation is the real
key and controlling agency of any type of instructional activity carried out by
the teacher or any auto-instruction. How far a teacher or learner has been
successful in realizing the instructional objectives can be made known
only through a well-planned strategy of evaluation.
BEHAVIOURAL TECHNOLOGY
“Any manifestation of life is activity”, says Woodworth and behaviour is
a collective name of such activities. The term human behaviour includes all
types of conative, cognitive and affective activities. Therefore, behavioural
technology, as one of the form of educational technology is utilized to study
and bring modification in the behaviour. The famous psychologist B. F. Skinner popularized the term
behavioural technology while making use of his theory of operant conditioning
for bringing the desired modifications in the behaviour of living organisms. The chief exponents of behavioural
technology are Flanders, B.F. Skinner, Anderson, and Amidon.
A behavioral
technologist tries to assess and modify the behaviour in terms of both antecedents
(i.e. events that precede behaviour) and consequences (i.e. events that follow
behaviour). These antecedent events may be environmental events or cognitive
events (i.e. thoughts, attitudes or perceptions) that are considered to
influence behaviour.
Use
and Application of Behavioural Technology
The uses and
application of behavioural technology may be summarized as follows:
Ø Analysis
of Behaviour: Behaviour technology will help in
analyzing the behaviour of individuals in a proper way. An analyst with its
help may state the behaviour in specific, observable behavioural terms, e. g.: he is daydreaming or wasting his time
in gossiping etc. Behaviorists have developed proper tools for the analysis
of such behaviour. E.g.: Flanders Interaction
Analysis System. With such an analysis of the observed behaviour, the
existing behaviour patterns or behavioral problems of the concerned individuals
may be easily determined.
Ø Setting
the Target Behaviour for Behaviour Modification:
Once the existing behaviour is known and analyzed into specific behavioural terms,
the help of behaviour technology may be taken for setting as well as stating
the target behaviour in specific behavioural terms. For example, if a student
behaves aggressively on the playground (showing undesired behaviours like
pushing, grabbing, kicking and threatening to hurt other children), the desired
modified target behaviour, according to a behavioural technologist, may be
defined as “participating non-aggressively”. As a result of such naming,
identifying and fixing of desired modified target behaviour in specific term,
the actual task of behaviour modification, then may became quite scientific,
purposeful and goal-oriented.
Ø Providing
Suitable Ways and Means for Behaviour Modification:
In its third step, behaviour technology supplies the necessary ways and means,
tools and techniques for the desired behavioural modification of the concerned
individuals. Here it can help:
v The
learners to acquire the desired learning experiences in the terms of knowledge,
understanding, skills, application, attitudes and values.
v The
teachers by suggesting ways and means for bringing changes in the learning and
acquisition behaviour of their students.
v The
parents, teachers, educational administrators, guidance personnel and social
workers, by suggesting suitable technology for the prevention and treatment of
behavioural problems.
v The
parents and teachers to work with their children and students for the optimum
growth and development of the desirable personality traits and behavioural
acts.
v The
teachers in learning proper teacher behaviour and acquiring needed teaching
skills through special behavioural technology techniques like interaction
analysis, micro-teaching, simulated teaching, term teaching, action research,
etc.
v The
teachers have to manage properly the classroom behaviour and interaction of
their students aimed at creating proper conductive environment for effective
teaching learning.
In this way,
behavioural technology may help the interested individuals to know the nature
of the existing behaviour, the nature of the target behaviour and the way and
means to meeting the gaps between the existing and target behaviours.
For inducing the desired
behaviour or for bringing the needed modification in the existing behaviour,
behaviour technology, as said earlier, makes use of its own technology
including appropriate learning principles based on operant conditioning and
social learning.
SYSTEMS
APPROACH
Meaning
of the term ‘System’
The term ‘system’ signifies the
meaning of wholeness or interrelationships between parts or elements and
self-regulation. Here it is explained more clearly in the light of some
well-known definitions.
R.
L. Ackoff (1971): A system is a set of interrelated and interdependent
elements.
A. K. Jalaluddin
(1981): A system may be defined as a dynamic, complex, integrated whole
consisting of a self-regulating pattern of interrelated and interdependent
elements organized to achieve the predetermined and specified objectives.
Parameters
of a System
Any system may
be described in terms of four basic parameters:
1. Input
- what is put in to a system
2. Process
- what goes on in a system
3. Output
- product of a system and
4.
Environmental context - refers to all
those conditions, factors and constraints related with the physical and social
environment in which the system operates.
These basic parameters
of a system can be diagrammatically represented as follows:
Environment
Environment
|
Input
|
Process
|
Output
|
Systems
Approach
Systems approach is a
technique based on the systems concept. In this approach, a problem is taken
into account in its totality and attempts are made to solve it in the context
of the i) predetermined objectives and ii) functioning of its interrelated
parts and the whole system under given environmental constraint.
Basically system
approach tries to have a control over inputs, process, outputs and the environmental
constrains. A system is maintained if it meets the requirements of the
objectives, and it does not need modification. But if there arises a need for
adjustment either in the contents of the inputs or in the process or both then we
may change or modify or develop in the existing norms under which the whole
system operates. In this way, various modes of adjustment in the components and
functioning of the system are tried and the most feasible one is retained for
getting the best results.
Steps
involved in Systems Approach
There are three major steps involved
in a systems approach:
Ø System
analysis
Ø System
design and development
Ø System
operation and evaluation.
System Analysis
System analysis is
concerned with the task of analyzing a system in the form of identifying its
elements, their organization, their function or performance individually or as
a whole in order to determine the need to make adjustment to ensure the
achievement of system namely inputs, process, outputs, and the environmental
constrains. It helps the designer of the system identify the constraints that
interfere in the attainment of system objectives.
System Design and Development
The system design and
development is related with the task of synthesizing. Here, attempts are made
to design and develop the system on the basis of the finding of the former.
The following
are the main activities undertaken in this step:
·
Determination of the objectives of the
system
·
Selection of appropriate devices, methods,
strategies and approaches
·
Formulating a scheme of comprehensive
programmes for the working of the system in relation to objectives.
System Operation and Evaluation
System operation and
evaluation is concerned with the actual operation of a system and its evaluation
in terms of the objectives for providing necessary feedback to bring desirable
improvement and modification in the structure and functioning of the system. If
the output of a system meets the expectations or requirements of the objectives,
the system can be allowed to carry on. The need for bringing necessary
alternation or improvement in the system is felt, then it can be done in some
of the following ways:
·
Working with the elements or inputs of
the system
·
Working with the functions of elements or
inputs
·
Controlling the process and interaction
among the elements of the system
·
Manipulating the environmental
constrains of the system
In this way, the system may be
restructured, reorganized and its functioning may be re-planned and re-operated
in view of achieving better results. These processes are continued till getting
best results in terms of the objectives with greater economy, precision and accuracy.

The school system (a system
of formal education) may be treated as a subsystem of the education system or a
system complete in itself. It may have instructional (related with the
cognitive development of pupils) and co-instructional system as its subsystem.
However both the instructional and co-instructional system may exist and
function quite independently as a complete system in themselves.
System
Approach to Education
System approach refers
to a well-thought technique for designing, controlling and using a system for
realizing the system objectives in the best possible ways. Its application in
the field of education will surely make the system of education
self-maintaining with its basic parameters operating scientifically on the
principle of feedback and equilibrium. As a result, system approach to
education is likely to solve various educational problem related with the
organization and management of the process and products of education. The
purpose served by systems approach in education may be summarized now:
ü It
can effectively improve the instructional system.
ü It
can bring efficiency in the school administration and management.
ü It
may help in seeking the maximum effective utilization of the men and material
resources.
ü A
systematic educational planning in terms of long-range goals and specific
short-range objective can be done by it.
ü It
may help in improving the examination and evaluation system.
ü Improvement
in the organization of co-curricular activities and other educational aspects
of brining conative and affective development of the pupils can be brought.
ü It may help in maintaining, controlling and improving the
guidance services of the schools.
ü It
may help in improving the training and development programmes, E.g. the training
of teachers (pre-service and in-service) may be effectively improved.
ü It
may prove an invaluable means for designing, controlling and improving the
systems of non/informal and adult education.
ü Over
and above, it may render valuable services in improving the quality of
education in all its aspects and dimension.
Steps
involved in System Approach to Education
Generally, in adopting
systems approach for the solution of the problems in education, the following
steps are employed:
·
Identification of the problem
·
Specification of objectives
·
Analysis of the task involved in
achieving the objectives
·
Systems analysis - analysis of the input
and constraints of the system in the context of the objectives
·
System design and development - by generating
alternative strategies (change in input process or constraints)
·
Identification of preferred solution in
a given context
·
Operation and implementation of
preferred solution
·
Evaluation of the effectiveness of the
performance in terms of specified objectives
·
Providing feedback in the light of the evaluation
for brining necessary improvement and modification.
The instructional work
and activities being inside a teaching-learning situation may be seen to work
as a subsystem of the education system. However in a particular
teaching-learning situation, it may be found to work as a self-regulatory and independently
functioning system along with its different constitutes or parameters.
CONCEPT
OF EDUCATIONAL TECHNOLOGY
In view of the
discussion carried out, the following conclusions can be drawn about the
concept of educational technology:
Ø The
earliest concept of educational technology was linked with the use of audio
visual aids like charts, models, maps specimen and concrete material. In this
sense, the term educational technology was used as a synonym to audio visual
aids meant for direct teaching and learning.
Ø With
the advent of physical science and consequently the electronic evolution there
came and era of sophisticated hardware and software like projectors, tape
recorders, radio and television. As a result educational technology was taken
in terms of these sophisticated instruments and equipment’s used for presenting
instructional material.
Ø Then
came the age of mass media.it led to a massive communication revolution for
instructional purposes. Utilization of radio, television, tele-text and
Computer Assisted instruction for individualized learning thus brought more
sophistication in the use of appliances and instruments for formal and informal
education.
Ø So
educational technology cannot be taken as a synonym to audio-visual aids and
technology in education emphasizes the concept of service, i.e., the use of
different equipment, gadgets and mass media.
Ø Educational
technology mean technology of education presenting itself as a system for
bringing improvement in the total process of teaching learning by carefully
analyzing its problems and reorganizing all available resources in an economic
way for obtaining the optimum results.
Ø Educational
technology cannot be viewed in terms of its parts or processes. Instructional
technology, teaching technology, behaviour technology, programmed learning,
micro-teaching, system analysis, management of teaching learning, teacher or
pupil behavior etc., are all its constituents and resources. All these
branches, innovations, approaches and strategies should be integrated as a
whole according to the needs and requirements of the system represented by
educational technology at a particular time in a given situation for accomplishing
its useful objectives.
Unit II: Instructional Media
INSTRUCTIONAL
MEDIA
Media
Media is the plural form of medium, which describes any channel of
communication. This can include anything from printed paper to digital data,
and encompasses art, news, educational content and numerous other forms of
information. Digital media, which makes up an increasingly vast portion of
modern communications, is comprised of intricately encoded signals that are
transmitted over various forms of physical and virtual media, such as fiber optic
cable and computer networks.
Instructional Media
Media are used to help the learner
achieve the learning objectives more effectively and efficiently. Common
instructional media are generally called as 'teaching-learning
aids' such as blackboard (chalkboard), charts, models, video film, radio,
etc. Some of these media are used to create readiness in the learners for
learning experiences. They provide clarity, precision and accuracy in
processing information. They create visual images which help retention of the
learnt concepts. Some of them also provide stimulation to more senses than one
(e.g. video film or instructional television). Some media provide opportunity
to the learner to learn individually at his own pace (e.g. CAI) or in a small
group (models, assignments, newspaper cuttings for discussion, etc.) or in a
large (e.g. 35 mm film or slides).
Instructional
media can be used in all phases viz. development, organisation and summarising
phases of classroom instruction. They can be used with learners of any age
group.
NEEDS OF INSTRUCTIONAL MEDIA
·
To form a clear idea of something
·
To stress the essential and leave the non-essential in the background
·
To give access to something which may be inaccessible
·
To clarify abstract information which may be difficult to communicate
verbally
·
To condense large quantities of information
·
To promote mental activity of students
·
To give feedback to the teacher about student
·
To encourage emotional response interest
·
To support to work of the teacher
IMPORTANCE OF INSTRUCTIONAL MEDIA
Compels Attention: The right use of audio-visual aids complex attention and
hence wins the interest of the pupils. It also helps to motivate students.
Firsthand
Experience: It provides
firsthand experience when teacher demonstrates a lesson, students perform
experiments themselves and prepare charts, models, etc.
Clearness of
Perception: Audio-visual aids
reduce the verbalism or useless phrases and hence leads towards clearness of
perception.
Learning Experience
is Made Concrete: It makes the
learning experiences more concrete and teacher can make the concepts clear.
Friendly Attitude
of Teacher: The teacher becomes
friend of students while using audio-visual aids. When teacher demonstrates,
shows models, or takes the students for out-door activities he becomes guide
and friend of students.
Time Saving: It saves time and learning becomes more effective.
Brings Vital
Reality: It brings vital,
fresh and intense reality in the classroom. Mere chalking and talking does not
solve the purpose. Only teaching aids can sharpen it.
Remove
Misconceptions: A film once seen
can be reviewed by discussion among students and with the teacher. It films is
shown again students can correct their faults and unconsciously overlooked
information are corrected simultaneously.
Solutions to
Teaching Problems: The timely use of
proper aids helps in solving partly or fully many teaching problems and hence
learning is improved.
Easiest Way of
Learning: It is the easiest way of learning. When an object is seen by
the child its image is formed in his mind.
Provides Variety and
Freshness: It breaks repetition of lesson and brings variety to the
class room technique which is always welcomed by the students.
Simplify Teacher's
Work: It makes the work of teachers simplified. A teacher can
handle large number of students at a time.
Freedom in the
Class-Room: It provides freedom
to the students in the class-room. They can discuss, comment and question. They
are inspired to do work without the fear of the teacher.
Scientific
Attitude: It gives
opportunity to develop scientific attitude and give training in the scientific
method.
Based on Principles
of Psychology: Audio-visual aids
are based on principles of psychology. It gives child-centered education.
To Cover Present
Curriculum: The extended field
of education can be covered only by using teaching aids.
CLASSIFICATION OF INSTRUCTIONAL MEDIA
The traditional
classroom teaching was an encyclopedic, memory oriented, recitative method only
concerned with accumulation and reproduction of a vast store of unrelated
isolated facts where memory was the focal point. Today it has been researched
and proved that “concrete experience should form the basis of meaningful
learning”. Thus we use a variety of teaching aids while teaching in the
classroom. The vast number of teaching aids has necessitated the need for
classification of teaching aids. Based on the use of two major organs; eyes and
ears, teaching aids are classified as;
Ø Audio
Aids
Ø Visual
Aids
Ø Audiovisual
Aids

EDGAR
DALE’S CONE OF LEARNING EXPERIENCES
A concept model of
utilizing the learning experience is popularly known as ‘Cone of Experiences’
and was developed by Edgar Dale. This
model is based on a board spectrum of educational methods and media. It has been
researched and established that, people generally remember:
·
10% of what they read - reading text
·
20% of what they hear - hearing words
·
30% of what they see - looking at
pictures
·
50% of what they see and hear - watching
a movie or demonstration
·
70% of what they say and write -
participating in a discussion, giving a talk
·
90% of what they say and do – doing a
presentation/teaching others
Our sense organs are
the gateways to acquire knowledge. It has been proved by research that, we
learn:
·
1% through taste
·
1.5% through tough
·
3.5% through smell
·
11.0% through hearing
·
83.3% through sight
Dale proposed that
learning is stimulated progressively from concrete (i.e. hands-on) experiences
to abstract (i.e. verbal and visual) symbols. The foundations for instruction
reside in direct sensory experiences companied with purposeful interaction with
stimuli sources. Dale’s cone is most useful as a guide for introducing and
building concepts. At the most basic and effective level of instruction,
students are introduced to new material through actual “hands-on experience or
doing the real thing”. Students see do and talk about the concept. Learning
will be effectively complied if these conditions are fulfilled. At the top of
the cone, or triangle is lecture and text. Dale’s model suggests that these
passive instructional modes are the least effective ways to introduce new
concepts to students. Between the top and bottom of the cone, dale have several
other levels are instruction including giving a talk, watching a demonstration,
seeing a film or picture.
The cone are
experience’ as a model has ten bands. The model suggests a comparative approach
to effective teaching- learning process. The model sources a progression of
learning experience from “direct purposeful experience to abstract verbal
expression”. The progression suggest that the effectiveness of teaching
increases from base to pinnacle. The verbal symbol provides the lowest amount
of learning and so it is put as the smallest band on the top. Direct purposeful
experience provides better learning and hence is indicated by the largest band
at the base. Starting from the pinnacle the dale’s cone consists of verbal
symbol (lecture) visual symbol (poster, pamphlet), recording, radio, still
pictures, motion pictures(film) educational television, exhibition, study
strip, demonstration, role play, model and project, finally ending at learning
by doing in the base.
All the experiences
that human beings derive are mainly from these sources:
Ø Direct
sensory contact that involves doing.
Ø Pictures
or some other forms of representation of objects which involves observing.
Ø 


Oral
or printed words which are symbolic





1. Direct Purposeful Experience
This forms the base of
the cone and represents reality as we experience it firsthand. It is the
experience gained through direct contact with the senses: handling, testing,
touching, smelling etc., “an ounce of experience is better than a tonne of theory”
and hence direct experience is the best possible method of teaching
effectively. For example: The best way to understand how hydrogen puts off a
fire is to hear the ‘pop’ sound. The spectacular kaleidoscope designs cannot be
described only seen to be believed.
2. Contrived Experience
A contrived experience
is an imitation of reality. It is like a working model, which is a replica of
reality and differs from the original in either size or in complexity. It is
not possible to present a real object/ event in all cases. In some cases the
real object may be two big, may be very minute, concealed etc. in such cases a
contrived experience would better serve the purpose since it is an edited
version which makes reality easier to grasp.
3. Dramatic Participation
Life is a short journey
in which it is impossible to experience everything firsthand directly. Also we
cannot experience things of the past. Dramatic participation is a means by
which certain real events are represented so that we can get as close to
reality as possible. Thus we participate in a reconstructed experience as close
to the original as possible. Puppt sours, pagents, pantomimes, tableaux, mock
conventions, plays , conventional dramas are various forms of dramatization
There is a distinction
between an observer and a participant. The experience is more meaningful when
one actively participates rather than merely watch it. A keen observer does get
the feeling of being in the actors shoes.
4. Demonstration
In this form the
student gets the experience by seeing how certain things are performed by the
teacher. In every subject where would be certain complicated, hostiy and
hazardous aspects which are better handled by teachers. In such cases the
students take a back seat role and become passive observers. But the
demonstration could be made meaningful and interesting by using inductive /
deductive approaches.
5. Field-trips
Field-trip is nothing
but an on-the-spot study of the aspects by bringing the students face-to-face
with reality.it is a bridge between the school and the community. There are
numerous opportunities for the school to utilize the community resources.by Field-trips
students get firsthand experience with phenomena and aspects which cannot be
brought into the classroom.
6. Exhibition/ Museums
An exhibit is something
which one sees as a spectator or visitor at exhibitions or museums. When it is
not feasible to go into the community, then the outside world is brout in to
the classroom in the form of exhibits and concrete representation of things.
Exhibits consist of working models, charts, replicas, specimens etc. in which
one is not involved in handling it or making it work but remains a passive
observer.
7. Still Pictures
Pictures,
illustrations, stereographs, slides, filmstrips and micro projections are
one-dimensional. They can be either projected on to a screen by means of
projection machines and accessory equipment or given for individual study. They
provide only visual experience whereas radio and recordings provide auditory
experience only. Television or motions pictures are presented in a proper
sequence where as these materials are individual items. The experience of
seeing is less ordered and formalized.
8. Motion Pictures and Educational
Television
Motion pictures present
an abstract version of the real event, with consequent losses as well gains.
The motion pictures can dramatize events effectively and make the experience as
close to reality as possible. In comparison with field trips, motion pictures
omit unnecessary details and presents only necessary aspects.
Television is one step
ahead of motion pictures since it can bring the real event as it actually
happens. A television telecast is often history in the making.
9. Radio and Recordings
Radio and recordings
are a very cost effective means of information transmission though the
communication is ‘one-way’ only. In comparison to television and motion pictures,
radio and recordings provide only auditory experience.
10. Visual Symbols
Black boards, charts,
graphs, maps, photographs, pictures are abstract substitutes of reality. Herein
the communication is by means of visual symbols. They tend to promote a keen
interest and better understanding concepts. For example: graphs can more
effective to show variation in variables, compared to mere numbers.
11. Verbal Symbols
They lie at the
pinnacle of the cone. They are the most abstract in nature. A verbal symbol may
be a word, an idea or a concept or a scientific principle, a formula, a
philosophical aphorism. The word, idea or scientific principle expressed has no
resemblance to the objects for which it stands. We can think of two verbal
symbols spoken and written. Linguistics considers the spoken word to be primary
and written to be secondary.
Interpretation of Edgar Dale’s Cone
of Experiences
·
Lower levels of the cone involve the
students as a participant and encourage active learning.
·
Lower levels include more stimuli and
are richer with regard to natural feedback- the consequences of action.
·
Higher levels compress information and
provide data faster for those who are able to process it.
·
Pictures are remembered (recalled)
better than verbal propositions.
·
Pictures
aid in recalling information that has been associated with them.
·
Upper levels of the cone need more
instructional support than lower levels.
·
As we go up the cone, abstractness
increases and is highest at the pinnacle i.e. verbal symbols.
·
As we go down the cone, concreteness
increases and is maximum at the base i.e., direct purposeful experiences.

can transfer money. In the field of education, mobile phone plays a significant
role. Mobile learning or m-learning is an educational system. Mobile
learning supports a continuous access to the learning process with the
help of mobile devices. Through mobile phone one can access internet for
getting information. The internet also helps the students to improve their
social life. It allows the students to communicate regarding their projects and
doubts. The use of internet in classrooms often allows the students to work in
a group and sharing their ideas. From these positive experience students can
improve their attitudes about learning. By using educational mobile apps one
can improve one’s knowledge and skill.

EDUCATIONAL
RADIO
The radio is the
cheapest and the most easily accessible of all these means. No doubt, its potential audience is very
large in comparison to the audience of other mass media. It caters needs to the people of different
ages and level of maturity ranging from a primary school child to its
grandfather.
While all these
attributes make it a wide-reaching means of mass communication, it has a
pedagogically strong reason for its use in education and that it its versatility,
leading to serve different purposes.
History
of Educational Radio
It was a great
invention that human voice could be transmitted by electromagnetic waves over
long distance without the help of a wire.
The radio which achieved it brought thereby a new age in the area of
communication.
In India, as early as
July 23, 1927, a radio station at Bombay was formally inaugurated by Lord
Irwin. It was followed by the Calcutta
Radio Station and the Delhi Radio Station.
According to the 1984 report (Broadcasting in India 1984;1). The All India Radio (AIR) network, one of the
largest in the world, consisted of 86 radio stations equipped with 162
transmitters. The development of educational
radio has two sides to it:
i.
The establishment of broadcast network
and
ii.
The preparation and production of
specific educational programs.
As far as the broadcast
network is concerned, the AIR as made a tremendous achievement having managed
to reach as much as about 90% of the population of this large country. It is matter or pride that it is one of the
networks in the world.
As for the educational
programs, the broadcast-projects that we discussed in the section suggest how
efforts had been all along towards both formal and non-formal education.
The attempt to make
school broadcasts more curriculum oriented and the attempt to make university
broadcasts supplement the correspondence education have made the educational
radio more purposeful and specific. The
broadcasts programs of non-formal education for the AIR have recorded tremendous
success in achieving worthy objectives in the areas of agriculture and rural
development.
The
introduction of educational radio can be viewed in five types
ü School broadcasts
ü Adult educational and community development
project.
ü Farm and Home broadcasts
ü University broadcasts
ü Language learning projects
Use
of Devices in Educational Radio
Some devices of
independent and accessory function have come into use along with the radio in
the recent days. Besides, these devices
have also been cheap enough to be within reach of a considerable large
proportion of the population. There are
two main devices.
Ø Audio-Tapes
Ø Radio-vision
Audio-Taps
Audio-taps can overcome
the limitations of educational radio broadcasts. It provides considerable freedom to the
students. It can be used when the
individuals need it and at any time and place convenient to them. The audio-tape permits a degree of privacy
and confidentially which is not possible in the case of radio broadcasts.
The audio-tape recorder
is comparatively inexpensive, simple to operate, durable and portable. This technology is available at commercial
level too.
Radio-Vision
Pioneered by the BBC,
the technique of radio-vision allows the subject matter to be presented through
two channels, the audio and the visual.
This is used by educational institution as a substitute for educational
television, Radio-vision has its own advantages:
ü It is economical.
ü It can cater to different categories of
learners.
ü It is easy to produce such programs at the
institutional level or at the learning Centre’s.
ü It provides visual support to the concept that
is taught.
Types
of Radio Programmes
Different types of
radio programmes are in vogue. These
types can be broadly categorized into two groups.
v Service-Based Types
v Mode-Based Types
Service-Based
Types
From the service point of view, radio programmes can be grouped into
different types.
Ø Music
Ø Spoken-work

Limitations
of Educational Radio
ü Educational radio programmes have not been
given adequate and appropriate broadcast time-chunk. This phenomenon causes inconvenience to
learners.
ü The technical staff concerned with the
planning and production of radio programme doesn’t have adequate knowledge of
the relevant pedagogical needs of the learners and their characteristics.
ü So unless there is a perfect co-ordination and
understanding between the two groups, no good production could ever be
achieved.
EDUCATIONAL
TELEVISION
Television is a widely
used telecommunication medium for transmitting and receiving moving images,
either monochromatic (black & white) or color, usually accompanied by
sound.
Major
Educational Values of TV
· Communication
using the TV can be effective because its can transmit a wide range of
audiovisual materials like film, objects, pictures etc.
·
Educational Television is a great equalizer of
educational opportunity.
·
It can bring the world of reality to the
classroom.
·
Television can save the time of both teacher
and taught.
· It can heighten the interest in the topic, as by
using zoom shots, magnification and split screen, the students gets good view
of whatever is being demonstrated or shown on TV.

Limitations of Educational TV
Ø TV, like film and radio, could lead to a class
of passive students.
Ø Television moves ahead at a constant
speed. Thus the students cannot pace
their educational technology learning.
Ø The
program schedules of TV, could raise administrative problems in some schools.
Ø As larger and larger numbers of students and
taught by TV, they will no longer have
personal contact with a teacher.
Major
Characteristics of Educational TV
Instructor Guide:
A teacher on camera leads the students through learning experiences.
Systematic Broadcasts: These
are related to course of study with objectives and planned learning
experiences.
Ordered and Sequential: The broadcasts
are presented at regular intervals in sequence one builds upon another.
Integrated: The broadcasts
are related to other learning experiences such as experimentation and problem-solving.
Advantages
of Educational Television
ü Social Equality of Education
ü Higher Quality of Instruction
ü Reduce Dependency on Teacher
ü Flexibility and Cost effectiveness
ü Use of the Best Available Teacher
ü Logically
simple
ü Combination of Audio and Video Components
ü Stimulation
ü Mass Education
Limitations
Finance: Schools,
using indigenous material can easily make bulletin boards, flannel boards etc.
They could also pool in their resources and buy a common set of devices which
could be borrowed from a central authority as and when required.
Poor Selection of Films: Most
of the audiovisual aids are irrelevant to the school needs. It is necessary to match student needs,
abilities and level with the audiovisual aids. Teachers are not properly trained
in use of audiovisual aids.
SELECTION AND INTEGRATION OF MEDIA IN TEACHING LEARNING PROCESS
The media have
significant place in organizing the process of teaching-learning, but selection
of appropriate media is a challenging task for the teacher as there are various
types of teaching aids. The effective media can be selected by employing the
criterion i) Teaching-Learning objectives ii) Learning Conditions or
structures.
Teaching-Learning
objectives
Media
should help to achieve the cognitive, affective and psychomotor objective among
the learners, since the attainment of objectives is the primary factor in the
teaching-learning process.
Learning
Conditions or Structures
Learning objectives can
be achieved only by creating appropriate conditions or situation. So, for the
selection and use of media in a classroom, suitable and conducive learning
structure or environment is a must.
It is very important to
consider when and how instructional media should be used during the teaching
process. ‘When’ means the situation which demands the use of such media while
‘how’ indicates the precautions to be observed during the use of these media.
Merely the collection of instructional media is not the success of the teaching
process and the teacher. The effective use is also important. Therefore the teacher should possess the knowledge
of methods and precautions for using the media effectively. The descriptions of
such precautions are given below:
Use
in Three Stage of the Lesson
The media aids should
be used in the three stages of a lesson namely, introduction, presentation and
recapitulation. All these stages have different objectives; during
introduction, the media are used to create pupil’s interest in the lesson. At
the presentation stage, they are used to clarify the minute facts and difficult
thought to the pupils.
Use
According to the Needs
The media should be
used in the class when these are needed. Without any need, their use would be
ineffective and it would merely the wastage of time. Also, there is possibility
of indiscipline in the classroom. So, it is more required to use properly than
in excess.
Sufficient
Time for Thinking and Observation
These
should not be merely displayed for a while but sufficient time should be given
to the pupils after displaying, so that they may observe and think about them
for a longer time. If the pupils want to ask questions related to the teaching
aids, they should be allowed to do so.
Ask
Questions
The
questions should be asked in the context of the material presented in the
class, because this practice will make the subject matter easy and clear. In
the absence of questioning, the teaching becomes ineffective and the presented
media fail to leave any effect.
Variation
in the Use of Media
It
is also essential to pay attention towards the boring conditions in the class.
The teacher should not present the same media aids all the time. This creates
boredom in the pupils.
Way
of Presenting
Media should be
presented properly in the class. The teacher should either hang the teaching
aids on the wall or display them on the table. He should never display the
teaching aids by holding them in his hands. With the teacher’s movement, the
teaching aids held by the teacher in the hands will also get disturbed. Hence,
the pupils cannot concentrate their mind on the teaching aids and their
attention gets divided or diverted.
Preparation
of the Background for Media
Before
presenting the media in the class, the teacher should prepare the background
about the subject-matter in the context of those aids. This concentrates their
mind very quickly and also saves the time.
Media
should be used to Clarify Difficult Parts of the Lesson
While presenting the media in the
class it should be decided which part of the lesson is much difficult and
complicated? It would be useful to use the media only to clarify effectively
and to make easy that difficult part of the lesson.
Removal of Media after Displaying
After
displaying, the media should be removed from the scene immediately, because the
pupils’ attention will remain diverted if the aids are not removed. Pupils will
look at these aids continuously and they will not pay attention towards the
teachers’ teaching. After Displaying
Media, Come to the Main Lesson
The
teacher should avoid the deviation from his main lesson. He should concentrate
on his lesson, otherwise the interest of the pupils will get eliminated and
indiscipline in the class will crop up.
ROBERT
GLASER MODEL (1962)
Robert
Glaser developed this model in 1962. It explains the relationship between
teaching and learning. It provides a simple and adequate conceptualization of
the teaching process. This model belongs to the category of psychological models of teaching.
Why this
teaching model is basic teaching model
- It is called Basic teaching model because it presents a
very basic analysis of the process of teaching in terms of the elements of
teaching.
- This model applies to all levels of education
i.e., elementary, secondary, higher etc.. It is also applied to subject
matter related to any subject as a teacher can use this model for teaching
them.
- Teaching for any length of time (40 minutes, 1
hour, weeks etc.) is possible using this model. It explains the whole
teaching learning process by dividing it into four basic components
- Instructional objectives
- Entering behaviour
- Instructional procedures
- Performance assessment
![]() |
Assumptions
of Basic Teaching Model
- It is developed on the assumption that “every
lesson assumes some knowledge on the part of the learner”
- Through instructional procedure, the teacher
guides the learner from entry behaviour to terminal behaviour.
Components of Basic Training Model
Step 1:
Instructional Objectives
The instructional objective is
those objectives that the student should attain upon completion of a unit of
instruction.
- These objectives may be stated in general,
specific or in behavioural terms.
- For instruction to be effective and
systematic, the instructional objectives are stated in behavioural terms.
Step 2:
Entering Behaviour
- Every learner has initial behaviour before he
enters teaching-learning process.
- It is essential to detect the entering
behaviour of the learner before giving instructions.
- It is just like previous knowledge of a
subject or the performance of the learner in terms of educational
abilities.
- This step is important because only after this
step the teacher can take the students from entry behaviour to terminal
behaviour.
Step: 3
Instructional Procedures
- It is the most active part of the teaching
process.
- It indicates the method, procedure, and strategies of teaching which
depends on objectives and entry behaviour of the learner.
- This component depends on two previous
components.
Step: 4
Performance Assessments
- Here ultimate behaviour of the learner is
tested so that feedback may be given.
- If the need arises objectives may be modified,
the instructional procedure may be improved and assessment of performance
is made again.
- Evolution techniques used for the purpose of
assessment tests are observation, interview, rating scale etc.
- All four basic components are interrelated
with one another. They interact and influence each other.
- If the performance assessment indicates that
the learners have not been able to achieve the objectives set for them,
necessary changes are brought about in any one or all proceeding
components of this model so that the goals of instruction are attained.
Description of Glaser’s Basic Training Model
Glaser’s
models may be described in terms of the fundamental elements as under:
- Focus: – This model attempts to
pin point the process and major activities comprising the entire teaching,
learning process. It also brings into the light sequence to be followed in
the instructional process.
- Syntax: – In this model flow of
activities is sequential as listed below:-
(a) First, the objectives to be followed are fixed in accordance with Blooms Taxonomy. (b) Then the entering behaviour showing the understanding and background of the student is determined.(c) Thereafter the instruction work is carried out to achieve the objectives keeping in view the entering behaviour of the learner.(d) The ultimate behaviour of the learner is determined by using a different type of tests. - Social system: - The
model describes a teacher dominated classroom climate. Here students are
receptive and appreciative of the teaching activities. The success of this
model depends upon the competency and ability of the teacher in term of
various skills like the formulation of objectives, use of proper
strategies, techniques of evolution etc.
- Principles of reaction: - Main
principles of reaction are as follows. (a) Principles of interdependence:
-The student’s responses are to be understood and dealt within the light
of the interaction and interdependence, process and assessments. (b) The
principle of active involvement: -Proper execution of this model requires
a lot of activity on the part of the teacher. The model requires the
active involvement of the teacher from the beginning to the end.
Understanding of the potential and deficiencies of the students is
required at every stage of the teacher in order to achieve the objectives.
(c) Principles of follow up: – An assessment is made after teaching. In
case the results are not accordance with set objectives, gaps and
deficiencies are found out by the teacher. Then he tries to rectify the
drawbacks by taking corrective measures.
- Support system: – The
teacher needs following support systems for its success.(a) Proper
environment: – proper teaching learning environment and situations are
required for the use of suitable teaching strategies.(b) Pre-service
and In service facilities:- availability of adequate pre-service and
in-service activities to the teachers to acquire needed skills for using
this model.(c) Availability of appropriate evolution device for the
assessment of entering and terminal behaviour of the students.
- Application: – Since
the model is quite systematic and structured, it is applicable to almost
all the learning and teaching situations. It implies a personal contact
between the teacher and the student. It implies a greater emphasis on the
competency of the teacher rather than on his personality.
IGNATIAN
PEDAGOGY - A PRACTICAL APPROACH
Introduction
The Ignatian
pedagogical paradigm is a method of teaching and learning that is rooted in the
Spiritual Exercises of Ignatius of Loyola. Ignatian Pedagogy was
published in 1993, after worldwide discussion and consultation, as a response
to questions teachers in Jesuit schools were asking about whether there was a
distinctively Jesuit approach to teaching itself. The foundational document The
Characteristics of Jesuit Education (1986) had articulated the identity and
mission of Jesuit schools and was received with an enthusiasm, which led to a
renewal of how Jesuit schools understood themselves. Ignatian Pedagogy aims
to do the same for the classroom teacher in a Jesuit school.
What is the Goal?
Ignatian education
strives to develop men and women of competence, conscience, and compassion. It
is a collaborative process between and among faculty and students which fosters
personal and cooperative study, discovery, creativity, and reflection to
promote life-long learning and action in service to others. The Ignatian
pedagogical paradigm is a practical teaching framework which is consistent with
and effective in communicating the Ignatian values and world view. Faculty,
regardless of discipline, can utilize this approach so that their teaching is
academically sound and at the same time formative of persons for others.
What is the Process?

Throughout the process,
it is important that faculty be sensitive to their own experience, attitudes,
and opinions lest they impose their own agenda on their students. The Ignatian
pedagogical process includes the following elements: context, experience,
reflection, action, and evaluation.
Through consideration
of the factors and context of students' lives, faculty create an environment
where students recollect their past experience and assimilate information from
newly provided experiences. Faculty help students learn the skills and
techniques of reflection, which shapes their consciousness, and they then
challenge students to action in service to others. The evaluation process
includes academic mastery as well as ongoing assessments of students'
well-rounded growth as persons for others.
Context
Since human experience,
always the starting point in Ignatian pedagogy, never occurs in a vacuum, we
must know as much as we can about the actual context within which teaching and
learning take place. We as faculty need to understand the world of our students,
including ways in which family, friends, social pressures, politics, economics,
media and other realities affect them. For a relationship of authenticity and
truth to flourish between faculty and student, there has to be built a mutual
trust and respect that grows out of a continuing experience of the other as
genuine companion in learning. We need to know how to create an atmosphere for
learning where we help one another and work together with enthusiasm and
generosity, attempting to model concretely in word and action the ideals we
uphold for our students and ourselves.
Experience
Experience for Ignatius
meant to "taste something
internally" which involves the whole person - mind, heart, and will -
because without internal feeling joined to intellectual grasp, learning will
not move a person to action.
To enhance learning, we
faculty should first create the conditions whereby students gather and
recollect the material of their own experience in order to distill what they
already understand in terms of facts, feelings, values, insights, and
intuitions related to the subject matter at hand. Later we guide students in
assimilating new information and further experience so that their knowledge
will gain in completeness and truth.
We select activities that
take students beyond rote knowledge to the development of the more complex
learning skills of understanding, application, analysis, synthesis, and
evaluation. Through an eclectic mix of direct activities (such as conversations
and discussions, simulations, role plays, laboratory investigations, field
trips, service projects, etc.) and vicarious activities (reading, listening to
a lecture, etc.). We strive to create learning experiences that involve the
cognitive as well as affective responses, having students consider the
questions, "What is this?" and, "How do I react to it?" We
also help students integrate learning experiences in the classroom with those
of home, work, peer culture, etc.
Reflection
Reflection and
discernment were integral parts of Ignatius' learning process. Reflection is a
thoughtful reconsideration of some subject matter, experience, idea, purpose or
spontaneous reaction, in order to grasp its significance more fully.
Thus, reflection is the process by which
meaning surfaces in human experience by:
·
understanding the truth being studied
more clearly;
·
understanding the sources of one's
sensations or reactions in the consideration; deepening one's understanding of
the implications for oneself and others;
·
achieving personal insights into events,
ideas, truths or the distortion of truth;
·
coming to an understanding of who I am
and who I might be in relation to others.
Reflection is a
formative and a liberating process, which forms the conscience of learners in
such a manner, that they are led to move beyond knowing, to undertake action.
Faculty lay the foundations for "learning how to learn" by engaging
students in the skills and techniques of reflection.
A major challenge to
faculty is to formulate questions that will broaden students' awareness and
impel them to consider viewpoints of others.
Action
For Ignatius, love is
shown in deeds not words. Faculty hope that students are impelled to move
beyond knowing to action−action that is for the welfare of society. It is our
role as faculty to see that opportunities are provided that will challenge the
imagination and exercise the will of the students to choose the best possible
course of action to flow from and follow up on what they have learned.
Through experiences
that have been reflected upon, students make the truth their own and serve
others. Faculty helps students to consider their experience from a personal,
human point of view, while remaining open to where the truth might lead.
Evaluation
Ignatian pedagogy aims
at formation, which includes but goes beyond academic mastery. Here we are
concerned about students' well-rounded growth as persons for others.
Traditional ongoing academic evaluation can alert faculty to possible needs for
use of alternative methods of teaching; it also offers special opportunities to
individualize encouragement and advice for academic improvement for each
student.
On the other hand,
periodic evaluation of the student's growth in attitudes, priorities, and
actions consistent with being a person for others is essential. Faculty should
foster relationships of mutual trust and respect which set a climate for
discussion and growth.
Useful evaluative
processes include mentoring and reviews of student journals, as well as student
self-evaluation in light of personal growth profiles, leisure time activity,
and voluntary service to others. Internal or external feedback may serve to
launch the learner once again into the cycle of the Ignatian learning paradigm.
What is the challenge?
Consistent use of the
Ignatian paradigm can help the growth of a student:
ü Who
will gradually learn to discriminate and be selective in choosing experiences
ü Who
is able to draw fullness and richness from the reflection on those experiences
ü Who
becomes self-motivated by his or her own integrity and humanity to make
conscious, responsible choices.
In addition, and
perhaps most importantly, consistent use of the Ignatian paradigm can result in
the acquisition of life-long habits of learning which foster attention to
experience, reflective understanding beyond self-interest, and criteria for
effective action. Such formative effects were characteristics of Jesuit alumni
in the early Society of Jesus. They are perhaps even more necessary for
responsible citizens of the third millennium.
The Ignatian
pedagogical paradigm applies to all curricula and students of all ages and
backgrounds, is fundamental to the teaching-learning process in and out of the
classroom, helps faculty be better teachers, personalizes learning, and
stresses the social dimension of both teaching and learning.
The challenge for
faculty, therefore, is to find ways to bring the Ignatian pedagogical paradigm
to the subjects we teach and the programs we run, knowing that it needs to be
adapted and applied to our own specific situations. Through this process we
will find ways to accompany our students on their journeys of becoming fully
human persons.
Unit III
ICT IN EDUCATION
ICT
Web Based Education
Commission (2000) US Kerry’s report: ICT can be defined as the use of hardware
and software for efficient management of information. i.e., storage, retrieval,
processing, communication, diffusion and sharing of information for social
economical and cultural upliftment.
The definition of ICT
can be given the idea that ICT consists of
Information:
its storage, retrieval and processing.
Communication:
between machine and machine and machine and man.
Technology:
scientific and technological aspects for managing information and communication.
Meaning
of ICT
Information and Communication
Technology (ICT) means the implementation of different branches of technology
in information and communication processing. In a broader sense, ICT is taken to refer to the whole set of technology
concerned with communication, manipulation of information, networking, data
storage, transmission - encompassing data, voice and video.
Importance
of ICT
ICT can dissolve the
barriers of time and place and it throws open to possibility to initiate the
human activity. The main Features of ICT making it ‘the tool of knowledge
society’ are, its user friendliness, speed, accuracy, high degree of
reliability, high storage of capacity, integrity, consistency, logicality,
diligence, versatility, low failure rate, durability and portability.
User Friendliness:
The usage of ICT has its basic root on the need of the one’s who use it or need
it today, this flexible use makes it a necessary tool for the developments in
all era of lifestyle. For example, usage of MS-word package for documentation.
Speed:
All the hardware utilities of ICT are very fast. The suitable applications of
ICT can work many duties in one minute which cannot be done by a man in his
lifetime. For ex, human genome project by computers.
Accuracy:
The accuracy of an ICT programme is consistently high and the degree of
accuracy depends upon the design of the programme. But we cannot ignore
technological errors, which may cause by human beings.
Diligence:
Unlike human beings, the ICT means one free from monotony, tiredness and lack
of concentration. The ways of ICT can pay attention to every minute thing. For
ex, computer based evaluation OMR.
Versatility:
Versatility is one of the most wonderful things about the applications of ICT.
It can be connected to a lot of wonderful devices - a simple usage of computers
to the charming networking or WWW.
High Storage Capacity: New inventions in the ICT field like blue-ray
chips led to an unimaginable storage capacity for information storage. For ex,
the newly produced SRAM chips (static random access memory) having one billion transistors
which helps to deliver PC with improved performance per watt.
Integrity:
Though ICT modes different modes can be connected together and they can work
together for the achievement of entire system. The best example for the
internet connectivity making a creative machine globally.
Consistency:
One of the importance features of ICT is its consistency in working
performance. The programmes we used through it happening in the same way and
continuing for a period of time.
Logicality:
Though ICT able to follow the law of logic to do a particular work.
Besides this,
characteristic like low failure rate, portability via new inventions like
laptops, mobile technology, Wi-Fi connectivity etc., can increase the wide
application of ICT.
E-LEARNING
E-learning is an
approach to facilitate and enhance learning using information and communication
technologies. It is a web-based learning combine local area network, wide area
network, satellite board cast etc.
E-learning
is an all en-compassing term generally used to refer to computer enhanced
learning, although it is often extended to the use of mobile technologies. E-learning is usually delivered via personal
computer. E-learning includes learning
delivered by communication technologic, like online lectures, tutorials,
performance support systems, simulations, job aids, games and more. Effective E-learning is often a blend of
methods. E-learning therefore is an
approach to facilitate and enhance learning through both computer and
communication technology.
Features
or Characteristics
of E-Learning
E-learning is a Self-Paced: E-learning
is self-directed in which the students can choose their contents, tools
according to their interests, needs and skill.
It designed around the learner or student centered.
E-learning is Child-Safe: No
dangerous for child since no chat rooms are needed, also no inappropriate sites
or outside email or advertising.
E-learning is Dynamic: In
e-learning content are delivered in real time not old text books or software.

make the student to study dynamically.
E-learning Operates in Real Time: In
e-learning you can get what you need and when you need it. It always has up to datedness
and readily accessible.
E-learning is Individual: Every
e-learner selects activities from a personal menu of learning opportunities that
are mostly relevant to his or her grade and skill level.
E-learning is Comprehensive: E-learning provides learning events and
activities from main sources, covering every imaginable topic, enabling the
e-learning to select a format, learning method or training provider.
E-learning enables a School or Educational
System: E-learning builds learning communities
by enabling the school, student, parent and community to forge strong
relationships.
E-learning is Interactive and Effective:
E-learning
is interactive and allows the learner to become actively involved with the
material for maximum retention of gained knowledge.

TELECONFERENCING
Teleconferencing means
telephone meeting among two or more participants through a telecommunication
medium. It is a general term used for linking people between two or more
location by electronics. Teleconferencing happens through a telecommunications
medium. It is an aggregation of a conferencing, video conferencing, and data
conferencing, and includes multiple participants in a live real-time session.
A teleconference is a
conference that is held through a telephone system or similar network features
like file sharing, joint presentation take place and other extra help to add
more functionality to teleconferencing.
Types
of Teleconferencing
Audio Conference: It
involves transmission of voice only which are amplified at each end by the
speaker system. It can usually be handled over regular telephone lines rather
than needing a satellite as only voice will be transferred. It’s the most cost
type.
Audio-Graphic Conference: It
employs voice plus graphic display capability. The most frequently used graphic
supplement is a facsimile machine which transmits electronically and reproduces
at remote location anything that can be written/typed on paper. The additional
cost of such operations is justified in cases where mathematical formulas and
visual diagrams are critical to understanding.
Video Conference: It
combines audio and video to provide voice communications and video images. It
can display anything that can be captured by a TV camera. The advantage is the
capability to display moving images.
Computer Conference: Uses
telephone lines to connect two or more computer and modems. It can be
synchronous or asynchronous. An example of an asynchronous mode is electronic
mail. Items generated on computer which are normally printed and then sent by
facsimile can be sent by e-mail.
Types
of Electronic Conferencing
Delayed Time: It
closely resembles electronic mail. The conference takes place in a simple
shared ‘mail box’ on the remote system.
Real Time Conference: It
is thoroughly interactive and more closely resemble a telephone conference
call. This type of conferencing is especially useful among smaller groups.
Advantages of Teleconferencing
Save Time: Content
presented by one or many sources is received in many places. Simultaneously and
instantly. Travel is reduced resulting in more productive time. Communication
is improved and meetings are more efficient. It adds a competitive edge that
face to face meetings do not.
Lower Costs: Costs
are reduced by keeping employees in the office, speeding up product development
cycle, improving performance through frequent meetings with timely information.
Larger Audience: More
people can attend. The larger audience with lower cost per person is possible
in this interactive.
Dynamic:
It requires the user’s active participation. It enhances personal
communication. When use well for learning, the interactive will enhance the
learning and the teaching experience.
Adaptable: Useful
for business, associations, hospital and institutions to discuss, inform,
train, educate, present.
Flexible:
With a remote receive or a transmit truck, a transmit or receive site can be
locate anywhere.
Security:
Signals can be encrypted when it is necessary. Encryption prevents outside
viewers.
Unity: Provides
a shared sense of identity. More often individuals or groups at multiplying
locations can be linked frequently.
Timely: For
critical information, sites can be linked quickly. An audio or point to point
teleconference can be arranged in three minutes.
u Teleconferencing
provides students with the opportunity to learn by participating in a 2-way
communication platform.
u Teachers
and lecturers from all over the world can be brought to classes in remote.
u It
offers uniform, quality-controlled instruction to learner scattered over many
or over a large area.
u Students
are able to explore, communicate, analyze and share information and ideas with
one another.
Disadvantages
of Teleconferencing
Interruption: People
who teleconference do so using landlines, cell phones and voice over internet
portal, or voice, phones. So there is a chance for interruptions during
telephone meeting when calls are dropped or internet connections go dead.
Lack of Eye Contact: Eye
contact is another key benefit you lose when teleconferencing.
Lack of Body Language: Teleconferencing
does not let you read participants body language, which can give you clues as
to whether you need to change your direction during the meeting.
„ Many
people are difficult to manage in single teleconference.
„ Initial
cost of equipment's is very high.
„ It
takes time to organize.
„ Staffing
needs can be significant.
„ Socializing
is less than face to face meeting.
„ The
absence of quality of service provides virtually no guarantee of a satisfying
and unsuccessful experience.
INTERACTIVE
WHITE BOARD
Introduction
An Interactive White Board is a
large, touch sensitive board which is connected to a digital projector and a
computer. The projector displays the image from the computer screen on the
board. The computer can then be controlled by touching the board, either
directly or with a special pen, finger, stylus or other device. The board is
typically mounted to a wall or floor stand. Most interactive whiteboards
connect to computers via USB cables. But some recent models communicate
wirelessly using Bluetooth technology.
Interactive
White Boards
v Interactive
white boards are a teaching and learning resource used for displaying and
interacting with content.
v They
are generally used throughout schools and workplaces.
v They
display a computer screen via a projector which can be manipulated by teachers
and students using either their hands as a mouse or specialized pens which are
included with the software.
v The
computer screen remains the same only enlarged on the whiteboard so teachers
and students can interact with the screen just as if it was on the computer by
opening files and completing any other general computer applications using our
hand or a pen.
How
to Use It or Advantages of IWB
Presentation and Projects
Students can present
multimedia projects with the help of IWB and control the entire presentation
without touching a computer keyboard.
Web Streaming and Video
Teachers can show
streamed or downloaded video clips using programmes like windows media player
and quick time. Clips embedded into multimedia presentation programmes can
easily be shown as well. The interactive features of the whiteboard allow users to pause, circle, annotate, highlight, etc. DVD
player can be connected to the projector too.
Printing and Saving Notes
Users can print or save
anything with the help of interactive white boards as they have written.
Teachers can put notes in a file on a shared server for students to download or
post notes on a web page or blog. Notes can also be printed and distributed. We
can allow students to participate in the presentation instead of simply copying
from the board.
Encouraging Critical Thinking
Interactive white
boards encourage critical thinking. Use whiteboard with concept mapping
software like inspiration or kidspiartion. If the teachers switch to outline
view students’ ideas could be written directly on the whiteboard. Though begin
the class can brainstormed together in an organized fashion.
Great for Demonstrations
To show students
how to use a particular application. Students can present multimedia projects
with the whiteboard, controlling the entire presentation without touching a
computer keyboard.
Colorful Tool
Students respond
to displays where color is employed, and marking can be customized both in the
pen and in the highlighter features to display a number of different colors.
Maximize the Use
of Limited Computer Access
One-computer
classrooms can maximize the use of limited computer access by using the
whiteboard.
Clean and Attractive
Tools
There is no
messy chalk dust or other by-product, which can limit use. While the board can
be used with regular dry erase markers, it is more likely to be used with the
electronic marking feature.
It is Interactive
The interaction
that transpires between the person at the computer, the users at the board, and
the computer itself is a unique and very adaptable arrangement.
Disadvantages of
IWB
§ Hard to write
neatly
§ Expensive
§ You need to
supply your own data.
ICT
FOR TESTING
Computerized
Adaptive Testing (CAT)
In this technology the computer
administering the test actually individually tailors the test to the student’s
achievement level. The first item of the
test is generally of middle-level difficulty.
If the student gives wrong answer for this question by using mouse of
keyboard, the computer offers somewhat easier questions. Contrary to this, if the student answers the
question correctly, a slightly more difficult question is offered to the
student. The number of questions
required to reach a pass or fail decision is considerably fewer and thus the
test time is shorter, a motivating factor especially for students with disabilities. In case the test is lengthy as in the case of
some online tests like BITS, all the students are highly motivated as the
results are given to them as soon as the test is complete or the time is
over.
Advantages
Immediate Feedback: The test can be scored immediately to provide
instant feedback to the students.
Graded Difficulty: Examinees are
offered questions at their ability level and are not frustrated or annoyed by
too-difficult or too-easy items in the test.
Improved Test Security: The computerized adaptive testing through a
computer program contains a large pool of questions as compared to the handful
of questions that make up any individual’s test. This makes it more difficult to artificially
boost one’s scores by merely learning a few questions or even types of
questions.
Self-pacing: Here examinees can work at their own
speed. If desired, the speed of
responses could also be recorded for additional assessment.
Possibility of Tutorial
Format: If any questions are missed by a student
could recycle and reappear later in testing, encouraging learning during the
test itself, as well as remediation of incorrect responses.
Possibility of
Multimedia Format:
It can include text, graphics, photographs, and even full-motion video clips,
with the possibility of manipulation of the positions of items as well.
Computerized Adaptive Testing (CAT)
is especially beneficial in the following assessment situations:
ü Classrooms
or programs with exceptionally large enrolments.
ü Practice
tests for any high-stakes test such as the GRE, SAT, or state proficiency
examinations.
ü Proficiency
protests, for use in placement. CAT tests are often used at the college level
to determine in what course level to place a student.
Figural
Response Item Testing
This testing is a form of assessment
used in the field of science, in which computers are used to administer a
graphics-oriented assessment.
Example: In science, students
might be asked to assemble a plant cell from a menu of cell components or
transform isomers of molecules using on-screen computer tools. The scores on this test help in assessing the
comprehension of basic concepts of the unit. Testing scores on such tests have
shown a positive correlation to student’s verbal and figural aptitudes.
There are programmes like Tenth
Planet’s geometry programme, which allow students to recognize patterns and
manipulate figures and shapes to show their understanding of them; Thinking
Reader software for students reading below grade level, which helps them learn
to summarize, reflect, question, and predict; quizzes in the software test
recall, inference, and vocabulary as well as tracking student performance; it
can print six different kinds of reports to monitor improvement.
ICT
FOR EVALUATION
Types
of Evaluation
While teaching, teachers may have
the choice of three major kinds of evaluation – diagnostic, formative and
summative in order to help them for taking wise decisions at the three stages
of the teaching-learning process.
Diagnostic
Evaluation
Such evaluation task if performed
prior to teaching may help in providing information what the students know
about a certain topic, contents of area of learning which is going to be taught
to them. In this way it may help the
teacher to plan his instructional programme suiting the needs, interest and
abilities of the students.
Formative
Evaluation
This type of evaluation is conducted
well during the teaching-learning process.
It helps by providing useful information to both teacher and students
about the strengths and weaknesses of their teaching and learning. In the light of this information, they may
plan and engage for the mid-course corrections in pace or content and
methodology of instruction.
Summative
Evaluation
It represents a final test or measure
of the student’s progress or gains made by him as a result of a course of
learning. The results of such evaluation
may be safely used for making comparison among students, placing them in order
of merit or taking decisions about their promotion and awarding degree or
diploma.

With the advent of science and
technology, human life has become highly complex and multidimensional. These
software packages provide a large spreadsheet consisting of several rows and
columns in which the data can be entered. It looks like a student’s report
card. Excel can perform simple and complex mathematical operations like
addition, subtraction, multiplication and division.
Uses

data to create a worksheet.
Ø Entering
data in cells, rows and columns.
Ø Processing
like sorting, subtotal etc., of data.
Ø Operating
with formulae and function.
Ø If
we want to calculate the total marks of the each candidate we have to enter the
appropriate formula into the worksheet.
Ø Preparation
of different types of charts.
Microsoft
Power Point
It
is also one of the software packages available in MS Office. It is very useful
for classroom teaching for the presentation of information in a colourful and
attractive manner.
Uses
