Abstract: Abstract: The study examined the effect of computer-assisted instruction (CAI) on pre-service teachers’ performance in reaction rate concepts. The research employed the quasi-experimental design of a one group pretest-posttest type. A sample of one hundred and fifty (150) pre-service teachers were selected from an accessible population of level hundred (L100) students from the St. Ambrose College of Education at Dormaa Akwamu in the Bono Region of Ghana. Reaction Rate Concept Test (RRCT) was used to gather data for the research. Percentages and Means were used to answer research questions. The results show that the CAI strategy has a positive effect on pre-service teachers’ performance on reaction rate concepts. The study again shows that the use of CAI can improve learners’ performance in science and can help learners in high- level cognitive performance. CAI strategy proved to be an effective conceptual change teaching strategy in science. Based on the results obtained, it is recommended that science teachers should adopt the CAI and other ICT related strategies in teaching for improved learning outcomes in Chemistry.
