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. Three (3) 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 randomized design
involving the pre-test and post-test was employed for the purpose of this study. The
result obtained at pretest for both groups had a p-value of 0.13955 at 0.05 significance
level therefore failed to reject the null hypothesis which stated that there was no
significant difference between the two groups at pretest. Results obtained at posttest
10−4 which is less than 0.05 therefore, the null hypothesis which stated that there
was no significant difference between experimental and control groups at posttest was
rejected. The rejection was attributed to the use of audio-visuals on the experimental
group. The findings revealed that the use of audio-visuals in teaching was most
effective way of improving students’ performance in the teaching and learning of
circulatory system in Integrated Science.
