• Both teachers and the students are convinced about the important contributions educational technology can offer. If properly selected and used, instructional materials can do the following:

• 1.) Arouse and sustain the interest and attention of the pupils/students to learn.

• 2.) Concretize abstract concepts/ideas to promote meaningful learning.

• 3.) Makes learning more permanent because of the rich experiences that they provide.

• 4.) Provide self-activities for independent learning.

• 5.) Increae vocabulary by eliminating verbalism.

• 6.) Develop continuity of thought.

• 7.) Increase the quality of learning while decreasing the time spent.

• 8.) Check pupils preparedness.

• 9.) Make learning more interactive, hence learning is improved.

FUNCTIONS OF EDUCATIONAL TECHNOLOGY

1. Improvement of Teaching:

Educational Technology analyses the process of teaching thoroughly. It tries to find out the different variables of teaching, their interlinks, effects upon each other, relationships, theories of teaching, phases of teaching principles of teaching, maxims of teaching etc. By developing the theories of teaching, it helps in improving the quality of education.

2. Analysis of the Teaching-Learning Process:

Educational Technology aims at analyzing the process of teaching-learning thoroughly. It tries to find out the different variables of teaching their interlinks effects upon each other, relationship etc.

It is also concerned with various phases of teaching. The principles of teaching and the maxims of teaching are also analyzed by it. Over all, it tries to establish better and better relationship between teaching and learning.

3. Improvement of Learning:

Educational Technology analyses the process of learning and the related theories. It facilitates more and more of learning in less time. It takes the help of various empirically established generalizations from psychology, sociology, physical sciences, engineering etc.

4. Fixing up Goals of Education:

The objectives of education are being reviewed and revised with the passage of time. Educational technology helps in finding out the right objectives. Everything in this universe is undergoing tremendous changes and with a very fast speed.

The needs and requirements of the people and hence education need be revised from moment to moment. Educational Technology helps in fixing up the right objectives in the light of the changed circumstances and changed environment.

5. Training to Teachers:

The changed type of environment with new curriculum and new materials is to be handled by the teachers. The teachers equipped with old strategies and methodologies of teaching will remain misfits.

Right type of training to the teachers is the need of the hour. Educational Technology can render its valuable help in the training of teachers also. The use of video tapes and close circuit T.V. will help the teachers to remodel and reshape their teaching behaviors suitably.

6. Development of Curriculum:

Keeping in view the objectives of education which have been finalized by education technology thereafter comes the question of developing right type of curriculum. Only a suitable type of curriculum will help in the attainment of goals.

Curriculum is the total teaching-learning environment which has to be modified and remodeled in the light of latest thoughts. Only educational technology can do this job of developing a suitable curriculum appropriately.

7. Development of Teaching-Learning Materials:

Teaching- learning materials are also as important as anything else in the teaching-learning process. They have to be in accordance with the environment of the learners. In this age of science and technology, the materials of teaching cannot be unscientific.

Everything of the society including values of life need be reflected in the materials. Only right type of materials will able to modify the behavior of the learner suitably making him a fit person for the society. Only educational technology can develop the required and the desired type of teaching-learning materials.

8. Teaching-Learning Strategies:

A strategy plays an important role in the hands of a teacher in every teaching-learning situation.

The strategy has to be the right one which should be according to the materials and is able to bring about effective teaching-learning. The different strategies are being evolved by educational technology. The knowledge of those strategies is a must for every teacher. Then only the teachers will be able to do justice to their jobs.

9. Development of Audio-Visual Aids:

Audio-Visual aids have always played an important role in the teaching-learning process. They need be used according to the times. The software aids, the hardware aids, the computer and other such appliances, equipment etc., have “to be used in the present type of teaching-learning environment.

10. Help in Overall Improvement:

Educational technology helps in locating the problems in the different areas of education. It also helps in remedying the draw-backs.

Evaluation of the teaching- learning process is also made better because through feedback, things are improved thoroughly and there is better control over the process of education. Thus, educational technology can revolutionize the whole process of teaching-learning.

11. Identification of Needs of the Community:

Educational Technology identifies the needs of the community. It helps in providing equal education opportunities to backward people, disadvantaged students and deprived sections of the society. It helps education to reach the remotest corner of the country.

12. Identification of the Needs of Class-Room Behaviors.

Educational Technology identifies the needs of class-room behavior. As the mass education has reduced the standard of education, the use of educational technology can maintain and improve the standard by the use of teaching aids and programmed instruction material. Educational Technology can inspire the students in the class-rooms for self-learning.

Technology serve as a teacher.

Technology makes the

world a new place.

SLIDE PROJECTOR

A SLIDE PROJECTOR is an opto-mechanical device for sowing photographic slides.

• 35 mm slide projectors, direct descendants of the larger-format magic lantern, first came into widespread use during the 1950s as a form of occasional home entertainment; family members and friends would gather to view slide shows, which typically consisted of slides snapped during vacations and at family events. Slide projectors were also widely used in educational and other institutional settings.

• Photographic film slides and projectors have mostly been replaced by image files on digital storage media shown on a projection screen by using a video projector or simply displayed on a large-screen video monitor.

COMPONENTS A projector has four main elements:

• electric incandescent light bulb or other light source (usually fan-cooled)

• reflector and "condensing" lens to direct the light to the slide• slide holder• focusing lens A flat piece of heat-absorbing glass is often placed in the light path between the condensing lens and the slide, to avoid damaging the latter. This glass transmits visible wavelengths but absorbs infrared. Light passes through the transparent slide and lens, and the resulting image is enlarged and projected onto a perpendicular flat screen so the audience can view its reflection. Alternatively, the image may be projected onto a translucent "rear projection" screen, often used for continuous automatic display for close viewing. This form of projection also avoids the audience interrupting the light stream by casting their shadows on the projection or by bumping into the projector.

HOW TO USE SLIDE

PROJECTOR ?

• Gather the slides you are going to use. Most slide projectors have a carousel that can hold approximately 80 slides. If you have more than 80 slides, you will have to split them into groups.

• Place each slide into the carousel one by one. Some slide projectors have a clamping system in which you have to release a clamp before you can load the slides.

• Press the power button, which is usually red and located somewhere along the top panel of the projector.

• Focus the first slide. Depending on your slide projector, the focusing will either be done automatically, or you will have to adjust it using the focus buttons.

• Move through the slides using the advance and reverse buttons. Pressing the advance button will make the projector progress to the next slide. Pressing the reverse button will make the projector backup to the previous slide.

• Press the power button when you are finished. Remove the slides if you are not going to view them again soon. You should also unplug the slide projector and store it in a safe place.
