Multimedia usage in teaching the human digestive system and its effects on students’ academic performance

Abstract

This study investigates multimedia usage for instruction and academic performance of students on a selected topic on integrated science of Junior High School students in learning Digestion in Humans at Oshiyie M/A. Recognizing the challenges students face with traditional teaching approaches, the research employs a descriptive quasiexperimental design involving two intact classes, each comprising fifty Form 2 students. One group, designated as the experimental group, was taught using multimedia resources, while the control group received instruction through conventional lecture methods over three weeks. Pre-tests and post-tests were administered to evaluate student performance, supplemented by questionnaires to assess the perceived effectiveness of multimedia instruction. The results showed that the experimental group achieved significantly higher post-test scores compared to the control group (p < 0.05). Additionally, students taught with multimedia demonstrated greater engagement and interest in learning Digestion in Humans, reflected in their higher mean scores relative to those taught via traditional methods (p < 0.05). Based on these findings, it is recommended that educators incorporate multimedia teaching strategies
