Abstract:
Purpose: 1. To find out high school pupils interest in different fields of science supplementary instructional materials. 2. To find out how much high school pupils utilized science supplementary instructional materials. 3. To find out the source of science supplementary instructional materials, and then how they are selected and utilized by high school pupils. 4. To use the pupils interest to produce and provide high school science supplementary instructional materials. Procedure: Questionnaires were sent to389 high school science pupils to determine their interest in science supplementary instructional materials and to sixty eight science teachers, ten librarians and eight audio-visual librarians to determine the general status of science supplementary instructional materials in their schools. The returned questionnaires were analyzed by percentage and mean. Major Finding: Both in quantity and utilization, it was found that there were more printed material than non-printed materials. There were no video-tapes, magnetic boards, electric boards and sand tables in the school. Science teachers had accepted instructional materials as their teaching-aids, Of all the teaching aids, books and black boards were most widely used, followed by experiments, real objects, demonstrations and hand books. Most instructional materials were provided by the school budgets. Few instructional materials were hand-made, received from other instructional sources, or exchanged with other schools. Most high school pupils were interested in chemistry and biology supplementary instructional materials. Printed materials with pictures, exercises and experiments were attractive to them. Books, handbooks, newspapers, spicemens and experiments were moderately used, while video-tapes, transparencies, flannel boards and electric boards were used less often. The materials used most often were borrowed from the schools libraries to used in classes and at homes. The reasons most pupils used science supplementary instructional materials were because of their interest in science, the recommendations of their teachers and their acceptance that science was very important for their future education. The result of using instructional materials was that pupils understood the lesson better, could explain or answer the questions related to the lesson, obtained more knowledge and better marks. Recommandations: 1. The schools should provide instructional materials in line with the pupils interest. 2. The schools should provide documentaries and instructional handbooks on how to use these materials. 3. The schools should give the pupils chance to use such materials. 4. The schools should arrange more science activities for the pupils such as clubs, exhibitions and contests.
