The study investigated the effect of Jigsaw-based Learning Strategy on Junior Secondary School student’s achievement in Basic Science in Gwagwalada Area Council of the Federal Capital Territory (FCT). The research design for the study was the quasi-experimental design. The study made use of two groups- experimental and control groups. The experimental group was taught with Jigsaw Learning Strategy while the control group was taught with conventional teaching strategy. The reliability index of the instrument was 0.89 using kuder- Richardson formula 21. The experimental groups comprised 65 male and female and the control group comprised 55 male and female students, making a total of 120 students. The instrument used to collect data in the study was Basic Science Achievement Test (BASAT). The t-test statistic was used to test the hypotheses, while means and standard deviations were used to answer the research questions. The study revealed that Jigsaw Learning Strategy was more effective in teaching Basic Science than conventional strategy. Thus, it was recommended, among others, that Jigsaw Learning Strategy should be used in teaching Basic Science at junior secondary level of the education system. Conferences and seminars on Jigsaw Learning Strategy should be organized for teachers in Federal Capital Territory schools.
