). Effect of the 5E Instructional Model on Physics Academic Achievement Based on Gender and Students’ Ability: A Case of Berekum Senior High Schools in Ghana

This study examined the effect of the 5E instructional model on Physics students’ academic achievement based on gender and students’ ability. The study employed a quasi-experimental design using the pre-test, post-test and delayed-post administered instruments to the experimental and control groups. The study involved two instructional strategies (5E instructional model and traditional teaching). Instruments known as Physics Students’ Academic Achievement Test (PSAAT) and Delayed Post Test (DPT) were used to gather data for the study. Mean scores, standard deviations and normalized gains were used to analyses data while ANCOVA and independent-sample t-test were used to test the hypothesis at the 0.05 level of significance. A significant difference was found between Physics students instructed with the 5E instructional model and those taught through the traditional classroom. Similarly, a significant difference was found between Physics high-ability student in the 5E instructional group and those in the traditional group. However, a non-significant difference was found between Physics low-ability students in the experimental and the control groups. Similarly, a non-significant different was found among gender concerning pre-test and post-test means scores. However, a significant difference was found among gender in favor for the male students. The study recommended that Physics teachers wanting to improve their students learning outcomes should adopt the 5E instructional model.
