An Analysis of the Relationship Between Powerpoint Instruction and Students’ Retention Score in Computer Science (Database Management System) in Colleges of Education in Rivers State

Abstract

The study was conducted to investigate the effect of power point instruction on students’ retention in computer science DBMs in colleges of education in Rivers State South-South of Nigerian. Two hypotheses guided the study. Four research assistants were trained and used for the study. The research assistants did the teaching and administered tests. COSAT were used for data collection. The instruments were validated by three experts, two from computer science and one in measurement and education. The internal consistency index was 0.79. The design of the study was a quasi-experimental study of pre-test and post-test, non-equivalent control group. Pre-COSAT and post-COSAT were administered few days before treatment begins. Treatment lasted for six/6 weeks, after treatment, both tests were reshuffled and administered as post-test COSAT. The research questions were answered using mean and standard deviation while the null hypotheses were analyzed using analysis of covariance (ANCOVA). The results of the analysis revealed that the experimental group obtained a higher mean retention score than the control group in the post-COSAT. The difference was significant. The male students also had higher mean retention scores than the female counterparts.
