BACKGROUND OF THE STUDY
One present concern about the quality of instructional materials arises not because our school have performed quality of education be simple improved in schools today emphasizes is learn on both qualitative and quantities curriculum content method and techniques and qualified teachers. With the increase in the number of schools as well as in student’s enrolment, there arise the problems of shortage of qualified teachers, physical facilities and instructional materials. This is the general desire and pursuit of quality education shown by the public because of the apparent falling standard in the performance of our educational instructions.
This is an era when school enrolment is on the increase tremendously and quality of the teachers leaves much to be designed educational technology can not be ruled out as an instructional innovation. According to Brown and Thornton (2001) the gradual shift towards the use of instructional material in education has been encouraged by increased availability of effective, appropriate and convenient materials, devices machine and classroom facilities designed for improving instructions, instructional materials are only equipment which are employed with the sense particularly that sight the use of audio-visual aid therefore become a necessity to supplement the available instructional resources and qualified teachers. The current stations of audio-visual material in Nigerian school is very cruel and unsatisfactory. The development occurred in stages 1960s, there were audio-visual aids or instructional materials in the form of education, television and radio broadcasting unit at both federal and state ministries of education in all subjects.
Before the official support for instructional material started coming from the university in 1960s, the pioneering audio-visual instructional effort was already carried used in teaching are the 16mm film strips, 8mm film maps slides, radio programmes and television programme, cassette, tapes and real objects.
The use of audio visual material is not without justification, as they are considered relevant to curriculum improvement and general learning teaching processes. The use of instructional material cannot be overemphasized.
