1.1 INTRODUCTION
Globalization and technological change processes that have
accelerated in tandem over the past years have created a new
global economy -Powered by technology, fueled by information and
driven by knowledge.?Nature of Educational Technology
So far no one is universally agreed upon the definition of the
term "educational technology." For most people the term brings to
mind such electronic gadgetry as film projectors, tape recorders,
television sets and micro-computers used as teaching tools. Other
people add such nonelectrical instructional materials as books,
photographs and charts. Still others subscribe to a definition that
includes not only items used in teaching but also equipments used
in educational administration--keeping students' records on the
micro film, communicating between schools by radio, correcting
entrance examination papers with the aid of a computer and the
like. In effect, educational technology can mean different things to
different people. Even those who have specialised in this field have
failed to arrive at a proper definition. However, in an attempt to
satisfy everyone, the Association for Educational Communications
and Technology in the United States have come to the following
definition: "Educational technology is a complex integrated process
involving people, procedures, ideas, devices and organisation for
analysing problems and devising, implementing, evaluating and
managing solutions to those problems involved in all aspects of
learning."In fact, there are two meanings attached to the definition of
the term o'educational technology." One meaning refers to the
detailed application of psychology of learning to practical teaching
problems. The second meaning refers to the application of
engineering principles in the development of electro-mechanical
equipments of such devices--pictures, tape-recorders, computers
etc. These two meanings of educational technology interact in
the design and use of equipment to provide control over the
learning situation, a rich array of stimulus materials (e.g., films) and
interaction between responses of the learner and the presentation
of instructional material.However, the correct meaning of the term "educational
technology" has been differentiated by Lumsdaine by using two
different symbols: ET-1, ET-2.The new term "educational technology" suggests itself
and it may be used to refer to a little beyond the use of equipments
and techniques that are associated with equipments. On the other
route, starting from programmed instruction, a wider conception of
educational technology tends to be reached. It is difficult to keep
programmed instruction within narrow bounds. Programmed
instruction begins to look as though it is a part of something larger
and this is educational or instructional technology. Programmed
instruction emphasises that the aims of teaching should be
analysed, the methods of accomplishing them made explicit and the
effects assessed as precisely as possible. These basic ideas are
applicable to the systems of instruction that do not necessarily
include the use of teaching machines. The term "technology", as Ofiesh (1964) observes, implies
the application of science to art.according to futurist Alvin Toffler, -Will not be those who can not
read and write, but those who can not learn, Unlearn & relearn?,
Concerns over educational relevance and quality co-exist with the
imperative of expending educational oppertunities to those made
most vulnerable by globalization - developing countries in general,
low income groups, girls and women and low skilled workers in
particulars.- Darnton and GiacolettFrom the above discussion we can conclude that information
technology refers to the information processing of the software
application on operating systems or hardware applications that
includes computers, videos, telephones and related equipments of
telecommunications, tapes, CDs etc.But it
seems a little awkward to observe that whereas the contribution of
some kind of technology is visibly felt in respect of the operation of
our hospitals, factories, farms and offices, our classrooms have
remained a unique example of backwardness by remaining
insensitive to the technological inputs and their influences.However, the effective integration of ICTS into the
educational system is a complex, om ultifaceted process that
involves not just technology, indeed, given enough initial capital,
getting the technology is the easiest part - but also curriculum and
pedagogy, Institutional readiness, teacher competencies and
longterm financing, among others.and more sophisticated
modern hardware like electronic computers, space satellites,
language laboratories etc.Programmed Learning and Educational Technology:
Educational technology can be regarded, as the application
of systematic knowledge about learning and instruction to teaching
and training with the aim of improving their quality and efficiency.When used appropriately,
different ICTS are said to help expand access to education,
Strengthen the relevance of education to the increasingly digital
workplace, and raise educational quality by, among others, helping
make teaching and learning into an engaging, active process
connected to reallife.In addition, teachers who have
traditionally perceived themselves as classroom's chief performers
-- lecturing, conducting recitations, leading class discussion -- can
feel demoted to a less prestigious educational role when they are
asked to have reading materials, radio, television or computers to
deliver the content of lessons.For solving the varied problems of education
successfully, educational technology consisting of various media of
mass communication, suitable child learning processes, and
modern testing and evaluation techniques are essential.Information technology (IT) is the acquisition, processing,
storage and dissemination of vocal, pictorial, textual and numerical
information by a micro-electronics - based combination of
computing and telecommunication.refers to -any communication or
representation of knowledge such as facts, data or opinions in any
medium or for, including textual, numerical, graphic Cartographic,
narrative or audiovisual forms.?Instructional Technology is neithers technology in education
nor technology of education but both and all pervasive which
pervades the whole teaching learning or engineering put it should
be taken as a sum total of all such aspects, which go a long way in
shaping the personality of the learner in a meaningful context.The point is that it is not merely a system of presentation, a
particular technique or a set of principles; it is a methodology for
discovering an efficient means of organising learning situatiens to
attain specified objectives.The factors
causing ihe progress of educational technology are:
(1) Student flood due to population explosion;
(2) Acute resource scarcities;
(3) Rising costs;
(4) Unsuilability of output.It spans a wide variety of areas that include but are not
limited to things such as processes, computer software, computer
hardware, Programming Languages and data constructs.Definition of Information Technology:
-Information Technology is a scientific, technological and
engineerning discipline and management technique used in

economical and cultural matters.?Programmed learning, though wide in scope, is only a part of
the broader concept of educational technology which must include
many areas such as the problem of innovation, resources of
learning, standardisation and compatibility of system components,
the training of personnel, educational productivity and the design of
educational plant.Altering
old leaching habits in order to master new ones entails not only theexpenditure of energy but also the risk of a teacher looking foolish
by committing embarrassing errors when attempting new
techniques in the classroom.* Easy availability of updated data
* Connecting Geographically dispersed regions
* Wider range of communication media.1.2.1 Concept of Communication Technology
Communication Technology is also comprised of two words
like -Communication & Technology?.The interaction of physical sciences with education provides
us with traditional aids, tools and hardwares such as paper, ink,
books, radios, lin-guaphones, films, etc.It should, however, be emphasised that techniques
such as critical path analysis, curriculum development methods and
task analysis are essential components as well as the hardware
system.Earlier educators used to advocate the use of audio-visual
aids in the process of teaching in addition to supplementary aids
such as pictures, charts, maps, models and various audio-aids.In this connection, Information and communication
technologies (ICTS) which include radio and television, and the
Internet - have been touted as potentially and powerful enabling
tools for educational change and reform.The term in its modern sense
first appeared in a 1958 article published in the Harvard Bussiness
Review, in which authors Leavitt and whisler commented that -the
new technology does not yet have a single established name.In short,
anything that renders data, information or perceived knowledge in
any visual format whatsoever, via any multimedia distribution
mechanism, is considered part of the domains space known as
Information Technology.It is processing of information interms of accessing
information, decoding information and sending it via a medium and
changer to the receivers.Definition of Instructional Technology :
Instructional technology is just what it sounds lie, using
computers, CD Roms, interactive media, modems, satellites,
teleconferencing and other technological means to support
learning.According to the Association fo Educational Communications
and Technoogy (AECT)
-Instructional Technology is often reffered to as a part of
educational technology but the use of these terms has changed
over the years.While instructional Technology covers the
processes and systems of learning and instruction, educational
techology includes other systems used in the process of developing
human capabilities?ET-2 means the application of scientific principles to instruction and
hence the emphasis is on objectives and performances.Our teacher and via him/her the
processes of educational resource generation have not properly
assimilated or understood the importance and relevance of
technology for the classroom.It modifies the learner's environment through
the various techniques of presentation, arrangement of learning
activities and organisation of physical surroundings.But both these meanings make the scope limited because
educational technology is also concerned with the management
and organisation of man and material both, so that they achieve the
specific objectives of planning and implementation.It modifies the learner's environment through
the varied techniques of presentation, arrangement of learning
activities and organisation of social and physical surroundings.Technology includes:
(1) Preparing pupils for learning experience;
(2) Reinforcing their values while pupils are sharing the ex-
perience;
(3) Relating the experience with the lesson and thus stimulating
further learning.We will also dicuss the need & significance of ICTS in
Education with specific reference to historical perspective and
emerging trends.Instructional
technology, today is widely accepted as the application of systems
approach in the systemic design of a learning system and as a
method or approach combined with the appropriate and necessary
media and material to bring about improvement in teaching -
learning - evaluation process.It developes new concepts like programmed learning,
microteching, Simulated teaching, video tape, projector and
computer etc.Analysis of contents in depth is carried out in this technology.1.3 CONCEPT OF EDUCATIONAL TECHNOLOGY
Meaning of "Educational Technology"
Words are of little interest in themselves but they do indicate
changes in thinking. Once the climate of opinion is right, one may
arrive at the word "Educational Technology" by different routes.Hence the heading has to
become audio-visual aids and programmed instruction, an odd
pairing since some forms of programmed instructions use only the
printed page.Frequently, teachers avoid attempting a new
instructional technique because it requires too much from them'in
energy, time, patience or skill to become adept in its Use.Gradually, the emphasis shifted to the employment of costly
gadgets such as video and computers and now the multi-media
approach.This requires modernisation in
educational management, modernisation of teachers, of learning
processes, strengthening of educational finance and emphasis on
non-formal education.As you know the half life of information continues to
shrink and access to information continues to grow exponentially,
schools can not remain mere venues for the transmission of a
prescribed set of information from teacher to student over a fixed
period of time.- UNSECO

styles to designing instruction
the selection of materials and tools to design and implement
a design.In modern education, we can
witness the impact of two forces; one, of physical sciences and
electronics and the other, of behavioural sciences, operating on theprocess of instruction.In fact, as long as programmed learning co-ordinates these
techniques, it is woven into the fabric of educational technology.This is because some
technologies are not accepted or only partly accepted because they
require too many adjustments of traditional methods of instruction
or administration.Thus the amount of change required in the existing habits
and the fear of failure or of decreased prestige can affect the
teachers' willingness to accept a new technology.To utilise educational
television (ETV), many teachers think that much training equipment
and general reevaluation of teaching goals and activities would be
required.Scope of Educational Technology
By taking into consideration the usefulness of educational
technology in all branches of education, one dare not deny thevastness of its scope.It is concerned with
achieving the goals--of maintaining internal discipline, adapting to
its environment etc.Especially
in developing countries like India, it has to be mastered and utilised
by educationists if they are to keep pace with each other and catch
up with the developed nations.As such both quantitative expansion
and qualitative improvement of education can be facilitated and
accelerated with the help of educational technology.The uniqueness of educational technology is characterised as:
(1) Use of a broad range of resources fo: learning;
(2) Emphasis on individualised learning; and
(3) Use of systems approach.The effectiveness of educational
technology depends on:
(1) Ability to achieve goals;
(2) To maintain itself internally; and

1.1 INTRODUCTION
Globalization and technological change processes that have
accelerated in tandem over the past years have created a new
global economy ―Powered by technology, fueled by information and
driven by knowledge.‖ The emergence of this new global economy
has serious implications for the nature and purpose of educationalinstitutions. As you know the half life of information continues to
shrink and access to information continues to grow exponentially,
schools can not remain mere venues for the transmission of a
prescribed set of information from teacher to student over a fixed
period of time. Rather Schools must promote ―Learning to Lear‖ i.e.
the acquisiton of knowledge and skills that make possible continous
learning over the lifetime. ―The illiterate of the 21st century‖
according to futurist Alvin Toffler, ―Will not be those who can not
read and write, but those who can not learn, Unlearn & relearn‖,
Concerns over educational relevance and quality co-exist with the
imperative of expending educational oppertunities to those made
most vulnerable by globalization - developing countries in general,
low income groups, girls and women and low skilled workers in
particulars. Global changes also put pressure on all groups to
constantly acquire and apply new skills. The international Labour
organization defines the requirements for education and training in
the new global economy simply as a ―Basic education for all,‖ ―Core
work skills for all‖ and ―Lifelong learning for all.‖
In this connection, Information and communication
technologies (ICTS) which include radio and television, and the
Internet - have been touted as potentially and powerful enabling
tools for educational change and reform. When used appropriately,
different ICTS are said to help expand access to education,
Strengthen the relevance of education to the increasingly digital
workplace, and raise educational quality by, among others, helping
make teaching and learning into an engaging, active process
connected to reallife.
However, the effective integration of ICTS into the
educational system is a complex, om ultifaceted process that
involves not just technology, indeed, given enough initial capital,
getting the technology is the easiest part - but also curriculum and
pedagogy, Institutional readiness, teacher competencies and
longterm financing, among others.
In this module we will get an overal idea about the concept of
ICTS. We will also dicuss the need & significance of ICTS in
Education with specific reference to historical perspective and
emerging trends.
1.2 CONCEPT OF INFORMATION TECHNOLOGY :
Today‘s world is a world of information explosion. This
information explosion is taking place in such a fast speed that even
a literate person is feeling as if he or she is illiterate being not able
to cope up with such an information explosion. Here the question
arises how is one to cope up with it? The answer is, information
technology (IT) that can help in coping with the informationexplosion. So, we can say that ―Information Technology is nothing
but coping up with explosion of Information.‖
Information technology (IT) is the acquisition, processing,
storage and dissemination of vocal, pictorial, textual and numerical
information by a micro-electronics - based combination of
computing and telecommunication. The term in its modern sense
first appeared in a 1958 article published in the Harvard Bussiness
Review, in which authors Leavitt and whisler commented that ―the
new technology does not yet have a single established name. we
shall call it information technology.‖
It spans a wide variety of areas that include but are not
limited to things such as processes, computer software, computer
hardware, Programming Languages and data constructs. In short,
anything that renders data, information or perceived knowledge in
any visual format whatsoever, via any multimedia distribution
mechanism, is considered part of the domains space known as
Information Technology.
Meaning of Information Techology (IT) :
Information Technology consists of two words Information
and Technology. If you know the two words you can understand the
word information technology together.
The term ―Information‖ refers to ―any communication or
representation of knowledge such as facts, data or opinions in any
medium or for, including textual, numerical, graphic Cartographic,
narrative or audiovisual forms.‖
―Technology is the practical form of scientific knowledge or
the science of application of knowledge to practical.‖
―Information Technology is any equipment or interconnected
system or sub system of equipments that is used in the acquistion,
storage manipulation, management transmission or reception of
data or information.‖
Definition of Information Technology:
―Information Technology is a scientific, technological and
engineerning discipline and management technique used in
handing the information, it‘s application and association with social,
economical and cultural matters.‖

    processing, communication and application of information‖

  • Darnton and GiacolettFrom the above discussion we can conclude that information
    technology refers to the information processing of the software
    application on operating systems or hardware applications that
    includes computers, videos, telephones and related equipments of
    telecommunications, tapes, CDs etc.
    Characteristics of Information Technology :
    Information Technology has the following Characteristics :



  • Acquistion, Storage, manipulation, management, transmission or
    reception of data or information.

  • Real time access to information.

  • Easy availability of updated data

  • Connecting Geographically dispersed regions

  • Wider range of communication media.1.2.1 Concept of Communication Technology
    Communication Technology is also comprised of two words
    like ―Communication & Technology‖. We have already discussed
    that technology is the science of the application of knowledge to
    practical purposes. You also know that information means any
    communication or representation of knowledge in any form. Now
    we will know what communication is?
    ―Communication‖ is an integral part of human existence. It is
    communication that decides the very identity of human beings
    Modern society is turning into an information society and
    communication is the exchange of information. It is the process &
    transfering information form a Sender to a receiver with the use of a
    medium in which the communication information is understood by
    both sender and receiver.
    ―Communication Technology‖ implies the knowledge, skills
    and understanding needed to exchange information verbally or nonverbally. It is processing of information interms of accessing
    information, decoding information and sending it via a medium and
    changer to the receivers. Medium or channel can be written or oral
    or gesture form of information through speech, action or any
    electronic machine.
    ―Communication Technology is the electronic systems used
    for communication between indeividuals or groups. It faciliates
    communication between individuals or groups. Who are not
    physically present at the same location. Systems such as
    telephone, telex, Fax, radio, T.V. and Video are included, as well as
    more recent computer based technologies, including electronic data
    interchange and e-mail.‖
    In short, communication technolgoy is the activity of
    designing and constructing and maintaining communication
    systems.
    1.2.2 Concept of Instructional Technology
    J. K. Galbriath in his book a the new Industrial state has given two
    main characteristics of every technology.
    They are:
    Systematic application of scientific knowledge to the practical
    tasks and
    the division of the practical tasks into sections and Subsections.
    Any Subject who meets these two norms of the
    characteristics is called instructional Technology. Instructional
    technology, today is widely accepted as the application of systems
    approach in the systemic design of a learning system and as a
    method or approach combined with the appropriate and necessary
    media and material to bring about improvement in teaching -
    learning - evaluation process.
    Instructional Technology is neithers technology in education
    nor technology of education but both and all pervasive which
    pervades the whole teaching learning or engineering put it should
    be taken as a sum total of all such aspects, which go a long way in
    shaping the personality of the learner in a meaningful context.
    Definition of Instructional Technology :
    Instructional technology is just what it sounds lie, using
    computers, CD Roms, interactive media, modems, satellites,
    teleconferencing and other technological means to support
    learning.
    Instructional technology has several different aspects. It
    includes the following.the process of designig instruction.
    the application of learning theories and
    styles to designing instruction
    the selection of materials and tools to design and implement
    a design.
    the evaluation of designs.
    the effective use of team work and
    the use of technology in support of the development and
    delivey of instruction.
    According to the Association fo Educational Communications
    and Technoogy (AECT)
    ―Instructional Technology is often reffered to as a part of
    educational technology but the use of these terms has changed
    over the years. While instructional Technology covers the
    processes and systems of learning and instruction, educational
    techology includes other systems used in the process of developing
    human capabilities‖
    Nature of Instructional Techonology :
    It‘s basis is science
    It studies the effect of science and technology upon education.
    It is a contiuous, dynamic, progressive & effect producing
    method.
    It developes new concepts like programmed learning,
    microteching, Simulated teaching, video tape, projector and
    computer etc.
    It accepts school as a system.
    It can not solve each an every problem of education. It can be
    used succesfully in teaching and instructional system only.
    It can not replace the teacher
    Characteristics of Instructional Technology :
    It is helpful in achieving cognitive objectives.
    It can meet the shortage of effective teachers
    With it‘s help, the purose can learn according to his needs
    and speed.
    It can control the individual differences.
    Analysis of contents in depth is carried out in this technology.1.3 CONCEPT OF EDUCATIONAL TECHNOLOGY
    Meaning of "Educational Technology"
    Words are of little interest in themselves but they do indicate
    changes in thinking. Once the climate of opinion is right, one may
    arrive at the word "Educational Technology" by different routes.
    One route starts from audio-visual aids! At first sight, it would
    appear that teaching machines could go under this heading; but
    those who work with teaching machines emphasise the importance
    of programmes rather than machinery. Hence the heading has to
    become audio-visual aids and programmed instruction, an odd
    pairing since some forms of programmed instructions use only the
    printed page. The new term "educational technology" suggests itself
    and it may be used to refer to a little beyond the use of equipments
    and techniques that are associated with equipments. On the other
    route, starting from programmed instruction, a wider conception of
    educational technology tends to be reached. It is difficult to keep
    programmed instruction within narrow bounds. Programmed
    instruction begins to look as though it is a part of something larger
    and this is educational or instructional technology. Programmed
    instruction emphasises that the aims of teaching should be
    analysed, the methods of accomplishing them made explicit and the
    effects assessed as precisely as possible. These basic ideas are
    applicable to the systems of instruction that do not necessarily
    include the use of teaching machines.
    The term "technology", as Ofiesh (1964) observes, implies
    the application of science to art. When we apply the science of
    learning and communication to teaching, we evolve a technology,
    i.e., the technology of instruction. In modern education, we can
    witness the impact of two forces; one, of physical sciences and
    electronics and the other, of behavioural sciences, operating on theprocess of instruction. Both these forces have contributed to the
    evolution and growth of educational technology. Fig. 1.2 makes the
    concept clear.
    The interaction of physical sciences with education provides
    us with traditional aids, tools and hardwares such as paper, ink,
    books, radios, lin-guaphones, films, etc. and more sophisticated
    modern hardware like electronic computers, space satellites,
    language laboratories etc.Programmed Learning and Educational Technology:
    Educational technology can be regarded, as the application
    of systematic knowledge about learning and instruction to teaching
    and training with the aim of improving their quality and efficiency.
    For this reason, a wide range of presentation, control and feedback
    devices may be employed such as teaching machines, stimulators
    and computers. It should, however, be emphasised that techniques
    such as critical path analysis, curriculum development methods and
    task analysis are essential components as well as the hardware
    system. In fact, as long as programmed learning co-ordinates these
    techniques, it is woven into the fabric of educational technology.
    The point is that it is not merely a system of presentation, a
    particular technique or a set of principles; it is a methodology for
    discovering an efficient means of organising learning situatiens to
    attain specified objectives.
    Looked at from another point of view, the job of the
    programmer can be regarded as that of providing appropriate
    opportunities for the pupils to learn. It is his task to discover what
    these may be and to arrange the environment of learning, as far as
    he is able to optimise these opportunities. He will, for example,
    have to determine in some cases whether simulation is as useful as
    the real thing in some learning situations.
    Programmed learning, though wide in scope, is only a part of
    the broader concept of educational technology which must include
    many areas such as the problem of innovation, resources of
    learning, standardisation and compatibility of system components,
    the training of personnel, educational productivity and the design of
    educational plant.
    If educational technology possesses any value at all, it is
    vital that the teachers in training shall be introduced to its
    philosophy and techniques.
    In fact, there are two meanings attached to the definition of
    the term •'educational technology." One meaning refers to the
    detailed application of psychology of learning to practical teaching
    problems. The second meaning refers to the application of
    engineering principles in the development of electro-mechanical
    equipments of such devices—pictures, tape-recorders, computers
    etc.
    These two meanings of educational technology interact in
    the design and use of equipment to provide control over the
    learning situation, a rich array of stimulus materials (e.g., films) and
    interaction between responses of the learner and the presentation
    of instructional material.However, the correct meaning of the term "educational
    technology" has been differentiated by Lumsdaine by using two
    different symbols: ET-1, ET-2. 'ET-1' refers to the application of
    technology to instrumentation useful to the process of teaching.
    This meaning in its essence is a hardware approach. It stresses the
    need to develop and use audio-visual aids for teaching. Due to this
    concept, the process of leaching is mechanised through production
    and use of teaching aids.
    ET-2 means the application of scientific principles to instruction and
    hence the emphasis is on objectives and performances. It is the
    software aspect. All programmed learning materials and teaching
    machines come under this.
    Educational technology is thus the application of scientific
    knowledge about learning and conditions of learning to improve the
    effectiveness of teaching and learning.
    Nature of Educational Technology
    So far no one is universally agreed upon the definition of the
    term "educational technology." For most people the term brings to
    mind such electronic gadgetry as film projectors, tape recorders,
    television sets and micro-computers used as teaching tools. Other
    people add such nonelectrical instructional materials as books,
    photographs and charts. Still others subscribe to a definition that
    includes not only items used in teaching but also equipments used
    in educational administration—keeping students' records on the
    micro film, communicating between schools by radio, correcting
    entrance examination papers with the aid of a computer and the
    like.
    In effect, educational technology can mean different things to
    different people. Even those who have specialised in this field have
    failed to arrive at a proper definition. However, in an attempt to
    satisfy everyone, the Association for Educational Communications
    and Technology in the United States have come to the following
    definition: "Educational technology is a complex integrated process
    involving people, procedures, ideas, devices and organisation for
    analysing problems and devising, implementing, evaluating and
    managing solutions to those problems involved in all aspects of
    learning."
    Extensive use of educational technology requires a left of
    change on the part of the teacher. This is because some
    technologies are not accepted or only partly accepted because they
    require too many adjustments of traditional methods of instruction
    or administration. Frequently, teachers avoid attempting a new
    instructional technique because it requires too much from them'in
    energy, time, patience or skill to become adept in its Use. Altering
    old leaching habits in order to master new ones entails not only theexpenditure of energy but also the risk of a teacher looking foolish
    by committing embarrassing errors when attempting new
    techniques in the classroom. In addition, teachers who have
    traditionally perceived themselves as classroom's chief performers
    — lecturing, conducting recitations, leading class discussion — can
    feel demoted to a less prestigious educational role when they are
    asked to have reading materials, radio, television or computers to
    deliver the content of lessons.
    Thus the amount of change required in the existing habits
    and the fear of failure or of decreased prestige can affect the
    teachers' willingness to accept a new technology. Electronic
    equipment may frighten teachers with its apparent complexity. At
    least a part of this fear comes from the expectation that something
    may go wrong during the lesson, making the teacher appear inept
    or unable to control the teaching situation. To utilise educational
    television (ETV), many teachers think that much training equipment
    and general reevaluation of teaching goals and activities would be
    required. However, such fears are baseless.
    The evolution of technology has in fact ushered in a kind of
    revolution in our occupational, social and educational world. But it
    seems a little awkward to observe that whereas the contribution of
    some kind of technology is visibly felt in respect of the operation of
    our hospitals, factories, farms and offices, our classrooms have
    remained a unique example of backwardness by remaining
    insensitive to the technological inputs and their influences. The
    reasons for this are not far to seek. Our teacher and via him/her the
    processes of educational resource generation have not properly
    assimilated or understood the importance and relevance of
    technology for the classroom. Also the overall ecology of the formal
    educational system is responsible to a considerable extent for this
    state of affairs.
    Earlier educators used to advocate the use of audio-visual
    aids in the process of teaching in addition to supplementary aids
    such as pictures, charts, maps, models and various audio-aids.
    Gradually, the emphasis shifted to the employment of costly
    gadgets such as video and computers and now the multi-media
    approach.
    In brief, it may then be said that the entire principle of educational
    technology lies in the :
    (1) Useof a broad range of resources;
    (2) Emphasis on individualised learning; and
    (3) Emphasis on systems approach to education.
    Scope of Educational Technology
    By taking into consideration the usefulness of educational
    technology in all branches of education, one dare not deny thevastness of its scope. It modifies the learner's environment through
    the various techniques of presentation, arrangement of learning
    activities and organisation of physical surroundings.
    The very purpose of educational technology is to facilitate
    and improve the quality of human learning. It is concerned with
    achieving the goals—of maintaining internal discipline, adapting to
    its environment etc. For solving the varied problems of education
    successfully, educational technology consisting of various media of
    mass communication, suitable child learning processes, and
    modern testing and evaluation techniques are essential. Especially
    in developing countries like India, it has to be mastered and utilised
    by educationists if they are to keep pace with each other and catch
    up with the developed nations. As such both quantitative expansion
    and qualitative improvement of education can be facilitated and
    accelerated with the help of educational technology.
    Today, technology of education is being developed with the
    aim not only of making education more widely available, but also of
    improving the quality of education which is already available.
    Educational technology is conceptualised audio-visual aids.
    What can it achieve most? Only to improve the quality of message
    and if it is taken in the form of problem-oriented technique, then its
    main concern will be the production of teaching-learning material.
    But both these meanings make the scope limited because
    educational technology is also concerned with the management
    and organisation of man and material both, so that they achieve the
    specific objectives of planning and implementation.
    Educational technology is concerned with providing
    appropriately designed learning situations, which hold in view the
    objectives of teaching. It modifies the learner's environment through
    the varied techniques of presentation, arrangement of learning
    activities and organisation of social and physical surroundings. The
    purpose of educational technology is to improve the quality of
    human learning.
    The uniqueness of educational technology is characterised as:
    (1) Use of a broad range of resources fo: learning;
    (2) Emphasis on individualised learning; and
    (3) Use of systems approach. The effectiveness of educational
    technology depends on:
    (1) Ability to achieve goals;
    (2) To maintain itself internally; and
    (3) To adapt to its environment.
    Educational technology is concerned with the disciplined and
    systematic approach to education and training. It is a sort ofinvestment in national development. Employment structures can be
    neatly geared to make the best need of development. The entire
    educational system is educational technology adapting itself to the
    changing environmental conditions. Thus ihe scope of educational
    technology has become very vast.
    Technology includes:
    (1) Preparing pupils for learning experience;
    (2) Reinforcing their values while pupils are sharing the ex-
    perience;
    (3) Relating the experience with the lesson and thus stimulating
    further learning.
    However, the factors responsible for the progress of
    educational technology also cannot be overlooked. The factors
    causing ihe progress of educational technology are:
    (1) Student flood due to population explosion;
    (2) Acute resource scarcities;
    (3) Rising costs;
    (4) Unsuilability of output.
    Hence there must be a focus on relationships of things
    between the various levels and internal working parts between the
    educational system and the environment.
    There is a heavy stress on innovation to achieve the needed
    improvements and adjustments. This requires modernisation in
    educational management, modernisation of teachers, of learning
    processes, strengthening of educational finance and emphasis on
    non-formal education.
    If educational technology will not cater to individualised
    learning, then there will be no individual development and social
    progress.
    1.4 INFORMATION AND COMMUNICATION
    TECHNOLOGY IN EDUCATION
    "Globalization and technological changes have created a new
    global economy powered by technology, fueled by information and
    driven by knowledge."
    The emergence of this new global economy has serious
    implications for the nature and purpose of educational institutions.
    As the access to information continues to grow rapidly, schools
    cannot be contented with the limited knowledge to be transmitted in
    a fixed period of time. They have to become compatible to the ever
    expanding knowledge and also be equipped with the technology to
    deal with this knowledge.Information and communication technologies (ICTs) — which
    include radio and television, as well as newer digital technologies
    such as computers and the Internet — have been proven as
    potentially powerful tools for educational change and reform. When
    used appropriately, different ICTs can help expand access to
    education, strengthen the relevance of education to the increasingly
    digital workplace, and raise educational quality by helping make
    teaching and learning into an active process connected to real life.
    DEFINITIONS
    "ICT stand for information and communication technologies
    and is defined, as a "diverse set of technological tools and
    resources used to communicate, and to create, disseminate, store,
    and manage information."
    "ICT implies the technology which consists of electronic
    devices and associated human interactive materials that enable the
    user to employ them for a wide range of teaching - learning
    processes in addition to personal use."

    USES IN EDUCATION
    ICT is being utilized in every part of life. Due to the
    increasing importance of the computer, students-the future citizens
    cannot afford to keep themselves aloof from this potential medium.
    In education, use of ICT has become imperative to improve the
    efficiency and effectiveness at all levels and in both formal and non-
    formal settings. Education even at school stage has to provide
    computer instruction. Profound technical knowledge and positive
    attitude towards this technology are the essential prerequisites for
    the successful citizens of the coming decades.
    It can be used for the following purposes :
    • To broadcast material, online facility or CD-ROM can be used as
    sources of information in different subjects;
    • To facilitate communication for pupils with special needsTo use electronic toys to develop spatial awareness and psycho-
    motor control;

    learning with E-leaming learning systems
    • To process administrative and assessment data.
    • To exchange and share ideas -among teachers for the
    professional growth.
    • To carry out internet-based research to enhance , educational
    process
    ADVANTAGES OF THE USE OF ICT IN EDUCATION:
    ICT encompasses all those gadgets that deal with the
    processing of information for better and effective communication. In
    education, communication process takes place between teachers,
    students, management and administrative personnel which requires
    plenty of data to be stored for retrieval as and when required, to be
    disseminated or transmitted in the desired format. The hardware
    and software like OHP, Television, Radio, Computers and related
    software are used in the educational process. However ICT today is
    mostly focused on the use of Computer technology for processing
    the data. In this context, advantages of ICT in education can be
    listed down as follows :
    • Quick access to information :
    Information can be accessed in seconds by connecting to
    the internet and surfing through Web pages.
    • Easy availability of updated data:
    Sitting at home or at any comfortable place the desired
    information can be accessed easily. This helps the students to learn
    the updated content. Teachers too can keep themselves abreast of
    the latest teaching learning strategies and related technologies.
    • Connecting Geographically dispersed regions:
    With the advancement of ICT, education does not remain
    restricted within four walls of the educational institutions. Students
    from different parts of the world can learn together by using online,
    offline resources. This would result in the enriching learning
    experience. Such collaborative learning can result in developing...
    • divergent thinking ability in students,
    • Global perspectives
    • respect for varied nature of human life and acculturation.
    • Facilitation of learningICT has contributed in shifting the focus on learning than
    teaching. ICT helps students to explore knowledge to learn the
    content through self study. Teacher can help the students by
    ensuring the right direction towards effective learning. Situational
    learning, Programmed learning, many Online learning courses are
    some of the example of self learning strategies that are being
    utilized with the help of ICT.
    • Catering to the Individual differences:
    ICT can contribute in catering to individual needs of the
    students as per their capabilities and interest. Crowded class rooms
    have always been a challenge for the teacher to consider the needs
    of every student in the class.
    • Wider range of communication media:
    With the advent of ICT, different means of communication
    are being introduced in the teaching learning process. Offline
    learning, on line learning, blended learning are some of the
    resources that can be used in educational institutions. Collaborative
    learning, individualized learning strategies can enhance the quality
    of group as well as individual learning. with the real society. This
    can ensure the applicability of knowledge.
    • Wider learning opportunities for pupils
    Application of latest ICT in education has provided many
    options to the learners to opt for the course of their choices. Many
    Online courses are available for them to select any as per their
    aptitude and interest. Students can evaluate their own progress
    through different quizzes, ready to use Online tests. This can
    ensure fulfillment of the employment required in the job market thus
    minimizing the problem of unemployment. It can also provide more
    efficient and effective citizens to the society as per the changing
    needs.
