Predictive power of two selection examination scores on Senior School Certificate Examination result of pre-degree science students of Benue State University, Makurdi, Nigeria

Abstract

This study examined the predictive power of two selection examination scores on Senior School Certificate Examination (SSCE) result of pre-degree science students of Benue State University Makurdi-Nigeria with a view to seeking alternative to multiple selection examinations. Out of 1240 candidates that came in for Preliminary Science programme for 2007/2008 session, only 380 passed (that is, a minimum of C grade in the five subjects- English, Mathematics, Biology, Chemistry and Physics). Of this number, 220 had records for Mathematics and Physics in SSCE and therefore form the sample for the study and total of 38 entered for UME Mathematics. Three standard examination results in Mathematics and Physics were used for analysis in this study with SSCE as dependent (criterion) variable and Prelim and UME scores as independent (predictor) variables. Scores from the three examinations were collated and used for analyses. The examinations were considered reliable and valid based on the fact that they were set by experts, subjected to necessary test conditions and had consistent records of good standard. Using Multiple Regression for analysis, it was found that Prelim and UME Mathematics did not significantly predict SSCE Mathematics, F2, 38 = 1.278, p > 0.05. While Prelim Physics and UME Physics significantly predicted SSCE Physics (F2, 209 = 3.789, p 0.05). It was recommended among others that the current selection examinations be improved upon through strict supervision especially UME to guarantee their public acceptance and credibility. Key words: Selection examination, predictive power, preliminary science, examination malpractice, standard.
