Effects of over-head projector on senior secondary school students’ achievement and retention in geography in Bosso Local Government Area of Niger State

Abstract

The study investigated the effects of overhead projector on senior secondary school students' achievement and retention in geography in Bosso Local Government Area, Niger State. Pretest-posttest experimental-control group design was adopted for the study. The population of the study made up of six hundred and fifty (650) senior secondary school (SSI) students in public senior secondary schools within Bosso Local Government Area. The sample size for the study is eighty- eight (88). Two research questions and two hypotheses guided the study Two public senior secondary schools were purposively chosen for the study while two intact classes from these schools were randomly assigned to experimental and control group. Geography Achievement Test (GAT) and Geography Retention Test (GRT) was used as instrument for data collection. The instruments were validated by two experts from Educational Technology Department and two experts from Geography Department, Federal University of Technology Minna. The instruments for data collection (GAT) was trial tested using test-retest method at an interval of two weeks, the reliability of the GAT was determined using Pearson-Product Moment Correlation (PPMC) Coefficient statistics. The result obtained was 0.78. Mean, standard deviation and t-test statistics were used to analyze the data collected. The result of the study revealed that the utilization of overhead projector did not enhance students’ academic achievement hence control group had mean (13.07) while experimental group that was taught with over-head projector had mean(9.5 2). Gender also revealed that female students retained higher than male students when taught using overhead projector. Based on these findings, it was recommended that secondary school teachers should be trained in appropriate and effective utilization of overhead projector and encouraged to incorporate its use in teaching and learning of geography in Senior Secondary Schools in Niger State.
