Effect of Powerpoint Instruction on Students’ Academic Achievement in Computer Science (Database Management System) in Colleges of Education in Rivers State

Abstract

The study investigated the ‘Effect of PowerPoint Instruction on Students’ academic achievement in Computer Science’. Microsoft Office PowerPoint Instruction Strategy (MOSPPIS) was used as the experimental variable while Lecture Method was the control. Two research questions and two null hypotheses guided the study. The study which adopted a quasi-experimental, pre-test, post-test, non-equivalent control group was carried out in the College of Education, River State. Sample of 346 two hundred level computer science student were used for the study. Two intact classes from each College of Education were used; the intact classes were taught meaning of database management using MOPPIS and LM groups. The instrument Computer Science Achievement Test (COSAT) was developed by the researcher and validated by three experts before using it for data collection. The instrument was administered as pretest and reshuffled as posttest. The research questions were answered using mean and standard deviation scores. The hypotheses were tested at 0.05 level of significance using analysis of Covariance (ANCOVA). The results showed that the experimental group taught with Microsoft PowerPoint Instruction Strategy (MSPPIS) obtained a higher mean achievement score than the control group in the post COSAT. The difference was however, not significant. The male students had higher mean achievement scores than their female counterparts. It was recommended among others that MOSPPIS should be given more emphasis in the training and re-training programmes of colleges of education computer science lecturers.
