The Efficacy of 7E-Learning Instructional Strategy on Students' Achievement in Physics Practical in Lagos State

This study examined the efficacy of the 7E-Learning instructional strategy on students' achievement in practical physics, as well as the moderating role of mathematical ability. Using a quasi-experimental pretest- posttest design, the study included two experimental and two control groups, with each group taught using a different instructional method. A purposive sample of 169 senior secondary (SS2) physics students participated. The study utilized two validated instruments: the 7E instructional strategy and the WAEC Physics Practical Achievement Test (WPPAT), with reliability coefficients of 0.73 (using the score pie method) and 0.97 (using the test- retest method). Data were analyzed using both descriptive and inferential statistics. Findings revealed that students in the experimental group outperformed those in the control group. Additionally, mathematical ability did not significantly influence students' achievement in practical physics.
