Hardware approach originated from physical science and engineering. This approach is a
byproduct of the scientific and technological developments of the 20th century. Hardware
approach is based on the concept of service. It is concerned with utilizing audio visual aid
materials like charts, models, slides, filmstrips, audio cassettes, audio CDs etc. The hardware
approach also makes use of sophisticated gadgets and instruments for educational purpose.
The technology used includes radio, television, gramophone, films, tape recorders, projectors,
video players and machines that aid in teaching, computers and mass media. All the teaching
mechanics used in a hardware approach makes teaching more effective in order to achieve
outstanding teaching objectives. This type of educational technology adopts a product-
oriented approach. This means that hardware technology utilizes the products of software
technology for its functioning. The products of software technology can be teaching
strategies, teaching learning materials etc. Thus it utilizes software technology for the
betterment of the process of teaching-learning. With greater ease and economy, the hardware
technology has the ability to hand over the educational benefits to the mass. It is thus the
application of physical science in education and teaching in education with which the
teaching process is being mechanized gradually so that maximum pupils may be educated in
minimum time at very low cost. Human knowledge has three aspects- preservation,
transmission and development. The history of preservation of knowledge is believed to exist
since the time of printing machines. At that time, the knowledge was preserved in the form of
books. The knowledge was also preserved through tape recorder and films. Another aspect of
human knowledge is its expansion and transmission. It is now supported by machines like
radio, television, mikes etc. Education technology has brought tremendous change in this
field. The correspondence courses and open Universities are the gifts of the hardware
approach. The third and the last aspect of human knowledge is its development. Provisions
are made for research in this aspect. This includes collection and analysis of data. For this
purpose, they use the computers and other electronic devices. So, it is clear that all the
aspects of human knowledge allow the use of machines. This mechanized way of teaching
process is the hardware approach of education technology. Hardware approach in educational
technology helps for knowledge explosion thus leading to an overall efficiency in the
educational system.

the users is not provided. Instead, it helps in production of various software materials which
are used for developing hardware appliances (which include teaching strategies, learning
material, evaluation tools, teaching models, programmed instructions etc.). Software
technology does not require any aid from the hardware technology for its delivery. It
becomes more useful and productive when assisted by the hardware technology. It does not
have a mass appeal and is costlier to run than hardware approach or hardware technology.
During World War II, instructional technology was used effectively. With the problems of
labor shortage, this method provided a methodology for training in a systematic and efficient
manner in United States. Followed by this, came the use of highly structured manuals,
instructional films and standardized tests. Behavior technology is a growing field of study
now, which uses technology as a means to solve educational challenges, both in the
classroom and in distance learning environments. The software approach or instructional
approach creates an active environment in which students not only inquire, but also define
problems of interest to them. Such an activity would integrate the subjects of technology,
social studies, mathematics, science, and language arts with the opportunity to create student-
centered activity. Multiple representations and enhanced visualization will improve their
skills and concepts empowering them. The benefits of software approach include increased
accuracy and speed in data collection and graphing, real-time visualization, the ability to
collect and analyze large volumes of data and collaboration of data collection and
interpretation and more varied presentation of results. Technology in general also engages
students in higher-order thinking, builds strong problem-solving skills and develops deep
understanding of concepts. All types of resources are used to make the learning easy.
Traditional teacher-centered approach in the classroom has been shifted from teaching to
learning. It is called student centered or resource-based approach, the student being the
resource. Learning through hearing alone proves to be the least effective means of learning.
Technology is a sum total of teaching, instruction, education, learning and engineering which
helps to shape the personality of the learner in a meaningful context. While hardware
approach means the use of machines in teaching, the software approach means the use of
teaching and learning principles.
· To determine the goals and formulate the objectives in the behavioral terms.
· To analyze the characteristics of learner.
· To organize the content in logical or psychological sequence.
· To media between content and resources of presentation.
· To evaluate the learners performance in term of achieving educational objectives.
· To provide the feedback among other component for the modification of learners.

The systems approach to course and curriculum design is no more than an attempt to use a
process of logical development and on-going monitoring and evaluation in order to allow
continuous evaluation of the course or curriculum to take place. In implementing the systems
approach, it is important to appreciate that, while the decisions taken at each stage are always
affected by earlier decisions, they may themselves necessitate some of these earlier decisions
being changed. It is also important to realize that the stages shown are not the only ones
possible, and that, once taken, a decision can always be reconsidered. The approach should
thus be dynamic and iterative, always allowing for second thoughts and the refinement of
ideas. For example, although you should certainly make a first attempt to define objectives
and learning outcomes very early in the planning, you will invariably need to come back to
re-define or add to them once you have worked through some of the later steps. The systems
approach can be used at any time when an episode of teaching/learning of any length is being
planned. It can be applied to long-term planning for a whole course lasting weeks, months or
years, through to daily lesson planning, or even to on-the-spot planning for a learning
experience of only a few seconds duration. It can be applied by a group of teachers designing
or adapting a complete course, as well as by an individual teacher preparing his or her
specific course input. The approach can also be used for analyzing a previous teaching or
learning experience. The systems approach does not prescribe or promote any particular
teaching methodology (for example, individualized study or group learning). Rather, it is a
vehicle that helps teachers to think more systematically and logically about the objectives
relevant to their students and the means of achieving and assessing these. On occasion,
analysis may suggest that 'chalk and talk' may be the most appropriate method for achieving
some objectives, but no one method will be appropriate for all objectives or for all students.

There are various stages in systems approach. They are the following:
SUMMARY
The chapter focuses on the three-tier approach of education technology. The three approaches
were first suggested by A.A. Lemsdein in the year 1964. The three categories of education
technology are- software approach, hardware approach and systems approach. Hardware
Approach is the application of physical science in education and teaching in education with
which the teaching process is being mechanized gradually so that maximum pupils may be
educated in minimum time at very low cost. Software approach use psychological principles
and learning theories in education. In software approach, the Psychology of Learning is
exploited for the production and utilization of software techniques and materials in terms of
learning materials, teaching-learning strategies, tools of evaluation and other devices to
soften the task of teaching and learning. Systems approach involves accurate identification of

the requirement of problem. System Approach is the setting of objectives after identifying
their needs in performance-oriented terms. Educational Administration and Management can
be made more effective and less costly by using in educational system. The systems approach
to the design and analysis of teaching or learning situations is the basis of the great majority
of modern educational technology-related developments.

GLOSSARY
Physical science: Physical science is a term to refer to branches of natural science and
science that study non-living systems, in contrast to the life sciences. Physical science is
ordinarily thought of as consisting of four broad areas: astronomy, physics, chemistry, and
the Earth sciences. Each of these is in turn divided into fields and subfields.
Audio visual aid: Audio visual aids are defined as any device used to aid in the
communication of an idea. This includes flash-cards, charts, diagrams, maps, brochures,
handouts, pictures, masks, film strips, motion pictures, slide presentation etc.
Behavioral Sciences: The term behavioral science encompasses all the disciplines that
explore the activities of and interactions among organisms in the natural world. It involves
the systematic analysis and investigation of human and animal behavior through controlled
and naturalistic observation. Behavioral sciences include two broad categories: neural -
decision sciences and social - communication sciences. Decision sciences involves those
disciplines primarily dealing with the decision processes and individual functioning used in
the survival of organism in a social environment. Communication sciences include those
fields which study the communication strategies used by organisms and its dynamics between
organisms in an environment.
