Impact assessment of the integration of e-Learning engrade system on the learning of physics in selected secondary schools in Ile-Ife
The study developed an e-learning engrade system for teaching Physics in selected secondary schools in Ile-Ife. It assessed the effectiveness of the system on the performance and retention of the students in Physics and also determined the impact of the system on students’ attitude towards Physics in the selected secondary schools. These were with a view to improving students’ learning outcomes in Physics in senior secondary schools in Ile-Ife. The study adopted the pretest, posttest, control group design. The population comprised all students that registered for Physics in all the senior secondary schools in Ile-Ife, from where a sample of 60 students was selected from two schools using purposive sampling technique based on availability of facilities like Information and Communication Technology, internet and supply of electricity. The 60 students were assigned into experimental and control groups containing 30 students each. Three research instruments were used for data collection. They were: Physics Achievement Test (PAT); Perceived Impact of the E-Learning Engrade System on Student Attitude towards Physics (PIESAP) and Student Attitude towards Physics (SAP). The stimulus material used was the e-learning engrade system, a web-based package with template for lesson delivery. It treated the following topics heat energy and linear momentum. The experimental group used the package independently for learning the selected topics by login in to www.engrade.com with their individual access code given to them by the researcher. The study lasted eight weeks. Data collected were analysed using mean, standard deviation and t-test. The e-learning engrade system was developed using the Microsoft Power Point with text and pictorial features. It contained user-friendly platforms such as flashcards, animations and quizzes which accelerate learning achievement by enabling teachers to connect learning resources to the students at the right time. The results showed that students that were exposed to e-learning engrade system performed significantly better than those taught using the conventional method (t = 17.52, p < 0.05). The results also showed that there was a significant difference in the retention abilities of the students that were exposed to e-learning engrade system and those taught using the conventional method (t = 15.77, p < 0.05). Furthermore, the results showed that there was a significant improvement in the attitude of students towards Physics after they had been exposed to the e-learning engrade system (t = 4.84, p < 0.05). The study concluded that the e-learning engrade system was a creative tool for improving students’ learning outcomes in Physics in secondary schools.
