Effectiveness of Audio-Visuals in Enhancing Understanding of Circulatory System

The objective for this study was to determine the effectiveness of audio-visual method of teaching over traditionally designed instruction on second year students of Awe Senior High Technical School in circulatory system. Two (2) research questions and two (2) null hypotheses were formulated to serve as guide for this study. Samples of two intact technical classes were placed into experimental and control groups. The study made use of a standardized achievement test items and a structured questionnaire as the instruments for data collection, the scores obtained were analysed using the t-test statistical method. Quasi-experimental non-randomised design involving the pre-test and post-test was employed for the purpose of this study. The result obtained in this study showed that out of the null hypotheses formulated and tested at 95% level of significance, one was rejected while the other was accepted. The rejection was attributed to the use of audio-visuals. The findings revealed that the use of audio-visuals in teaching was most effective way of improving student’s performance in the teaching and learning of circulatory system in Integrated Science.
