Using the multi-media approach to enhance teaching of biology at Techiman Senior High School

Abstract

The study focused on enhancing Senior High School students‟ performance in biology using the multi-media approach. The research was a quasi –experimental design involving Three General Science classes. The sample was one hundred and five (105) students of Techiman Senior High School in the Techiman municipality in the Brong-Ahafo Region of Ghana. Purposive sampling technique was adopted for selecting the sample for the study. The experimental group Form Two Science students composed of thirty five students were taken through the multi-media approach of teaching while Two Science students made up of thirty seven students, the control group continued with the traditional method of teaching. The students were taught for six weeks and were made to take a test composed of essay type questions before and after each lesson. The data of the study was collected by using the instructional packages, pretest and posttests. The lesson plans were used to observe and monitor the trend of conceptual understanding of biological concepts through written answers, practical skills and students‟ responses and explanation of phenomena. The findings of the study showed that the performance of students‟ exposed to multi-media approach of teaching were enhanced. The study recommends more and deeper research on multi-media approach of instruction in teaching abstract biological concepts in Techiman Senior High School.
