This study investigated the Effect of Computer-simulation on Students’ Performance and Retention in Chemical Reaction concepts among Secondary School students’ in Katsina State, Nigeria. The study was guided by two objectives, two research questions and two hypotheses, some of the objectives of the study include; Determine the scores of students when taught chemical reaction concepts of chemistry using computer simulation instructional strategy and those taught using conventional teaching method in Katsina State; Quasi-experimental research design using pretest, posttest and retention test non-randomized groups were used. The Population of the study comprised 4,505 SS2 students from the twelve public secondary schools in Katsina metropolis. Purposive sampling techniques was used to select 128 students’ from two intact classes of two public secondary schools. The instruments, chemical reaction performance test was used for data collection. The instruments was validated by 3 experts. Reliability coefficient of the instruments was established at r=0.78. Mean and standard deviation were used to analyze the research questions. All the hypotheses were analyzed using paired sample t-test at 0.05 Alpha level of significance. The Findings of the study revealed that; significant differences existed between academic performance of students taught chemical reaction concept of chemistry using Computer-simulation instructional strategy and conventional teaching method in favour of Computer-simulation instructional strategy (t = 4.345, p-value = 0.00, df = 127. Since the p-value of 0.00 less than alpha value = 0.05,); significant difference existed between the retention ability of the students taught chemical reaction using computer simulation and those taught same concept using conventional method (t = 3.103 p-value = 0.002 df = 127. Since the p-value of 0.00 less than alpha value of 0.05). Based on the findings the, study recommended that; Chemistry teachers’ should encourage performance and retention rate of students by using Computer-simulation for teaching chemical reaction concepts. Government should encourage teaching using Computer-simulation instructional strategy by providing necessary facilities needed for its effective implementation and organizing seminars, conferences and workshops on teaching using computer simulation.
