Efficient Use of Audio-Visual Equipment in Teaching and Learning: It’s Implication to School Supervision

Abstract

This paper aimed at determining the possible effectiveness of the use of audio-visual equipment in English, Math and Science subjects to the academic performance of grade 8 learners in Talangan Integrated National High School. Three sections of grade 8 and their teachers in English, Math and Science became part of this action research. At the end of the study, implication to school supervision was lined-up to improve teaching strategy among teachers. The three sections of Grade 8 (Courteous, Caring and Charity), with a total number of 102 became part of the population for this study. This paper is a qualitative, experimental research which took note on the performance of the learners in three subjects – English, Science and Mathematics. Three quizzes were given on all subjects after each session without the use of audio-visual material. After that, audio-visual materials are used and another three quizzes were given after each session. Without the use of audio-visual material, the mean level of learners are 5.48, 6.91 and 4.27 in English, Mathematics and Science, respectively, in quizzes which are out of 10. On the other hand, the mean level of learners in a quiz with 10 items and using audio-visual material are 9.00, 8.48 and 4.45 in the said three subjects, respectively. Using t-test for paired sample mean, it was found out (with the assurance of the p-values 0.01, 0.00 and 0.22 for English, Science and Mathematics, respectively) that the use of audio-visual materials significantly improved learners performance only in English and Science. Recommendations to teachers, school heads, district and division officials, and to future researchers were given at the end of the study. Implications to school supervision, especially on classroom observation, are also mentioned to guide school heads and master teachers in improving teaching strategy among teachers.
