The purpose of this study was to examine the effect that the use of Computer Simulation-Based Instruction (CSBI) in teaching CRR in Physical Sciences, as one of the alternative strategies to traditional teaching, would have on the academic achievement of Grade 12 learners in this topic. The Cognitive Theory for Computer Simulation-Based Instruction was the theoretical framework guiding the study. The study employed a mixed method approach and a sequential explanatory design was used. The population was all Grade 12 Physical Sciences learners in Mopani District of Limpopo Province in South Africa. The sample consisted of one hundred and eighteen learners in two classes, from two secondary schools located in a rural area; one of which served as experimental and the other a control. The experimental group was taught CRR using CSBI and the control group using the traditional teaching approach. The null hypothesis tested was: There is no significant difference in academic achievement of learners taught using CSBI and those taught using traditional teaching approach. Data were collected using pre-test and post-test in the quantitative phase of the study. Test on Chemical Reaction Rate Concepts (TCRRC) and Attitudes Towards Chemistry Lessons Scale (ATCLS) were the research instruments used. The qualitative data were collected using semi-structured interviews with five purposively sampled learners from each of the two groups and analysed using the qualitative content analysis technique. The quantitative data were analysed through the independent t-test. There was a statistically significant difference in the scores of the experimental group and the control group in the post-test with a moderate effect size in favour of the experimental group. The findings were that CSBI improved learners’ conceptual understanding of CRR and was therefore a more effective teaching approach than the traditional method. The findings are expected to inform Chemistry educators, subject advisors and curriculum developers on strategies that can improve the academic achievement of learners, in CRR, in Chemistry.I online resource (xvii, 300 leaves : color illustrations, color maps)enUniversity of VendaTraditional InstructionUCTDConceptual UnderstandingCognitive Theory for Computer Simulation - Based InstructionComputer Simulation - Based InstructionLearner - Centred InstructionChemical Reaction RateAcademic AchievementThesisJere S.
