Like other audio-visual aids to teaching, television has some of the following limitations

Like other audio-visual aids to teaching, television has some of the following limitations:

1. One-way Communication.

One way communication is the major limitation of educational television. Earl C. Kelley has remarked, “TV is a real and present menaced to the freedom of teacher and learner. It cannot provide for two-way communication.” The teacher on the television can never enjoy the rapport with the student and he cannot share their understanding or confusion. The students cannot ‘talk back’.

2. Adjustment with School Hours Difficult.

Listening to and viewing a particular TV programme in school hours would very often require the teacher to re-arrange the school schedule. To do that is generally out of the question, you cannot do so without creating some confusion.

3. Telecasts not related to School Curriculum.

There is the further difficulty that the subject-matter of even the most educationally profitable telecasts may have little relation to the school curriculum, or the part of it that is currently being taught. Classes cannot be made to work on identical timings. Some will be completing a study that others have just begun. It is impossible to have schools and teachers so regimented that scores of classes are turning the same page of the same book at a given instant.

4. Financial Difficulty.

There is its financial aspect. Not all schools can afford to have a television set. Only the schools rich in finances can go in for television sets.

3. Educational Use of Films

Classroom use of films or sound motion pictures has brought about a revolution in the field of education. In fact, communicating through sound and sight simultaneously, the motion picture blends words, pictures, “objects, motions and even colour to make lasting impression on the children’s minds.

Broadly speaking, the educational use of motion pictures may be summed up as follows:

1. Motion pictures enrich the learning process and lead to greater all round achievement.

2. Motion pictures directly modify beliefs in desirable directions and cause students seek additional information about subject studied.

3. Motion pictures help in the improvement of educational achievement by different subjects.
