Effect of constructed model of human Ductless gland on academic achievement and retention of students of Biology in Minna metropolis. Implications for dwindling economy in Nigeria

Abstract

This study investigated the effects of constructed model of Human Ductless Gland on Academic Achievement and Retention of students of Biology in Minna Metropolis: Implications for a dwindling economy in Nigeria. The research design adopted for this study was pretest-posttest randomized control group design. Senior Secondary two (SSII) students in public secondary schools in Minna Metropolis were used for the study. Sixty students (60) participated in the study captured from two selected schools. The instrument used for data collection was a teacher made Biology Achievement Test (BAT). The questions were subjected to expert's assessment for face and content validity. To find out the reliability coefficient, test-retest method was used with an interval of two weeks and the scores collated and analyzed using PPMC and coefficient of r=0.85 was obtained. Four null hypotheses were formulated and tested at 0.05 level of significance. One of the findings of this study was that the use of constructed model facilitated student's achievement and retention in Biology. Based on the findings it was recommended that the government should organize seminars, workshops and conferences for teachers on the construction of models to enhance academic achievement and retention of students and also saving the monies spent on the importation of foreign models for teaching in Nigeria especially in this current dwindling economy.
