Effects of Instructional Methods and Ability on Polytechnics Students’ Academic Achievement in Workshop Practice in Delta and Edo States

Abstract

The study examined the effects of Instructional methods and ability on polytechnic students’ academic achievement in workshop practice in Delta and Edo States. Three research questions were raised and answered and three corresponding hypotheses were tested. A non-equivalent pre-test, post-test, quasi-experimental research design using a 3×3 factorial design was adopted for the study. The population of this study comprised a total of 235 National Diploma Year II workshop practice students in three government-owned polytechnics in Delta and Edo States for the 2022/2023 session. The research questions were answered using mean scores and standard deviation while the hypotheses were tested with one-way ANOVA. The findings of the study showed that there was no significant difference in the mean academic achievement scores among low, medium and high ability polytechnic students taught workshop practice using demonstration and project-based instructional methods while there was a significant difference in the mean academic achievement scores among low, medium and high ability polytechnic students taught workshop practice using lecture instructional method in Delta and Edo States. It was therefore concluded that students who went through demonstration and project-based instructional methods in workshop practice significantly improved in their academic achievement irrespective of their initial ability levels.
