Abstract

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.

Highlights

It is very clear that the world that we live in is constantly being moved by the progress being made in science and technology especially in the developed countries of the world
Is there any difference in post-test scores between the experimental group students who learnt with audio-visuals and control group students who learnt with the traditional method of teaching?
The results and discussion were presented in the order of the research questions and the null hypothesis

Summary

Introduction

It is very clear that the world that we live in is constantly being moved by the progress being made in science and technology especially in the developed countries of the world. Nation states that have developed have utilised the opportunities offered by the current phenomenal increase in science and technology especially information and communication technology, biochemistry and material science. Such nations have scaled the poverty barrier and moved into the club of rich countries. Some of these countries including Singapore, South Korea and Malaysia, which in the 60s were at the same developmental level as Ghana have witnessed improvement in their economies through the development and application of science and technology (Anamuah-Mensah, 2004). Since Ghana want to develop rapidly there is the need for science, mathematics and technology to become the pivot of their education starting from the early childhood
