Abstract

Over the years, Chemistry students’ results in secondary schools in Volumetric analysis have not been encouraging. This could be attributed to many factors among which ineffective teaching methods is part, hence this study on Effect of Improvised Materials on Chemistry Students’ Achievement in Volumetric Analyses in Ondo North, Nigeria. A pre-test – post-test Quasi-experimental design was adopted involving total enumeration of 150 (65 male and 85 female) SS2 Chemistry students from two co-educational schools purposively selected and grouped as experimental group and control group. Guided by two hypotheses, data collection was done using validated and VAAT (KR-20=0.78), which were analysed using Analysis of Covariance. The result revealed a significant effect of treatment on students’ VAAT post-test score (F(1; 147) = 165.80, p < 0.001); and a significant effect of gender was observed in favour of female students (F(1;147) = 180.22, p < 0.001). The study concluded that improvised laboratory instructional materials were effective on female students over the male students. It was recommended that teachers should adopt improvised laboratory materials in teaching volumetric analysis at the senior secondary school and all students irrespective of their gender should be considered in the selection of instructional materials in teaching volumetric analysis in Ondo North Senatorial District, Nigeria.
