Effectiveness of Multimedia in Algebra Instruction on Junior High School Learners

Abstract

The study determines the effectiveness of using multimedia resources to enhance the teaching and learning of algebra for Junior High School (JHS) 2 learners at Nii Ogle Basic 1 Model School, Bediako. Algebra is a fundamental mathematical concept, but many students struggle to comprehend its abstract nature. Multimedia resources, such as videos, animations, and interactive software, offer a promising solution to this challenge. This research investigates how multimedia can be used to improve students' understanding and retention of algebraic concepts, increase their motivation and engagement, and develop their problem-solving skills. A quantitative research approach was employed for the study. A pretest and a post-test control design were used.  PowerPoint presentation with videos was used as an intervention to teach algebra. The sample size for the study was 30 JHS at Nii Oglie Model 1 Basic School, Bediako of which 22 were males representing 73 per cent and 8 females representing 27 per cent and the majority of the learners were between the ages of 13 and 15. The researcher employed purposive and convenient sampling techniques for the selection of the learners and the school respectively. Significant improvements in knowledge gain (p<0.01) and student engagement (p<0.05) were observed in the multimedia group compared to the traditional group. The results show that the use of multimedia resources significantly improved students' performance and attitude towards algebra. The study recommends the integration of multimedia resources into instruction for JHS 2 learners to enhance teaching and learning outcomes.
