Instructional Materials, Students’ Achievement and Retention in Physics in Abak Local Government Area, Akwa Ibom State, Nigeria
Keywords:

The study investigates the instructional materials and students’ achievement and retention in Physics in Abak Local Government Area, Akwa Ibom State, Nigeria. A quasi-experimental research design was adopted; the population for the study comprised all the Senior Secondary two Physics students for the 2025/2026 academic session in the 11 public co-educational Secondary Schools. A sample of 68 SSII students drawn from two schools in their intact classes through a purposive sampling technique was used for the study. The Physics Practical Test was used as an instrument for data collection. It was validated and subjected to reliability analysis with KR21 statistics. The result showed a reliability coefficient of 0.89 and was deemed appropriate for the main study. Mean and standard deviation were used in analysing the data, while ANCOVA was used in testing the hypotheses at 0.05 alpha level. The results showed that students taught using locally produced instructional materials showed significant achievement in their Physics scores compared to the standard instructional materials. Students taught using locally produced instructional materials showed significant retention in their Physics scores compared to the standard instructional materials. It was recommended that teachers should locally produce instructional materials to improve student achievement and retention in Physics.
