Impact of Phet Simulation Instructional Strategy on Students’ Interest and Achievement in Biology in Senior Secondary Schools in the FCT, Abuja, Nigeria
Abstract
This study investigated the impact of Physics Education Technology simulation instructional strategy on senior secondary school students’ interest and achievement in Biology in the Federal Capital Territory , Abuja, Nigeria. The study adopted a quasi-experimental research design and was guided by four research questions and four null hypotheses. The population comprised 14,891 Biology students in public senior secondary schools in the FCT. A sample of 123 Senior Secondary School II students drawn from two intact classes participated in the study. The experimental group consisted of 65 students, while the control group comprised 58 students. Data were collected using the Biology Interest Assessment Scale and Biology Achievement Test . The instruments yielded reliability coefficients of 0.79 and 0.83 respectively. The experimental group was taught selected Biology concepts using PhET simulations, while the control group received instruction through the conventional teaching method for six weeks. Mean and standard deviation were used to answer the research questions, while independent-samples t-test was used to test the hypotheses at the 0.05 level of significance. Results showed that students taught using PhET simulations recorded higher interest (M = 46.98, SD = 4.84) than the control group (M = 35.57, SD = 5.19), and higher achievement (M = 75.71, SD = 3.13) than the control group (M = 58.71, SD = 4.25). The differences were statistically significant. However, no significant gender differences were found in interest or achievement among students exposed to PhET simulations. The study concluded that PhET simulation is an effective and gender-inclusive instructional strategy for improving students’ interest and achievement in Biology. It was recommended that PhET simulations be integrated into Biology instruction and that teachers be provided with appropriate training and technological resources.
