Effects of Constructed Model of Human Urinary System on Secondary School Biology Students' Academic Achievement and Retention in Minna, Niger State, Nigeria

Abstract

This study investigated the effect of Constructed Model of Human Urinary System on Secondary School Biology Students’ academic achievement and retention in Biology in Minna Metropolis. A pre-test post-test control quasi experimental design was adopted for the study. Four research hypotheses were formulated and tested at 0.05 level of significance. Simple random sampling was used to select three secondary schools in Minna Metropolis which were randomly assigned to experimental and control group. A total of 95 senior secondary school II students were used for the study. Pre-test was given to the two groups before the treatment to know their entry behavior. Post-test was given to the two groups after being taught Mechanism of Urine Formation for four consecutive periods to test for their academic achievement. A week after the post posttest was given to test for their Retention on the concept being taught, the results shows that the group taught with Constructed Model (experimental group) performed better and had good retention than students taught with Conventional Lecture Method which is the control group. Government schools’ management and teachers should realize that teaching with constructed models enhance learning. Education sector should endeavor to organized seminars, conferences and workshop on how to produce constructed models or inexpensive instructional materials for use in schools so as to enhance students’ academic performance and retention.
