ABSTRACT

The research aimed to explore the impact of improvised instructional materials on the academic performance of secondary school students in Basic Science and Technology within Ekiti State, Nigeria. The study employed a quasi-experimental pre-test, post-test, non-equivalent design. The target population comprised all junior secondary school two (JSS2) Basic Science and Technology students in Ekiti State. A sample of 120 students was selected through a multi-stage sampling technique, and data were collected using a self-constructed instrument titled Basic Science and Technology Achievement Test (BASATAT). The instrument's face and content validity were ensured, and its reliability was established through the test-retest method, resulting in a reliability coefficient of 0.75. Two research questions were formulated, leading to two corresponding hypotheses tested at a 0.05 significance level. Research questions were addressed using statistical measures such as mean and standard deviation, while hypotheses were analyzed using t-test and ANCOVA. The findings indicated that students exposed to Basic Science and Technology instruction with improvised materials exhibited significantly higher academic achievement compared to their counterparts in the conventional group. The study recommends that Basic Science and Technology educators enhance their creativity by incorporating locally available instructional materials from their immediate environment when standard materials are unavailable. This approach is suggested to positively impact students' achievement in Basic Science and Technology.
