The study investigated effect of Spaced Learning Strategy (SLM) on students? achievement and retention in trigonometry concepts of mathematics in Minna metropolis. The design of the study was quasi-experimental. The target population of study was 4,707 SSII students out of which a sample of 255tudents was selected using simple random sampling. Two research questions were asked to guide the study while two hypotheses were formulated and tested at 0.05 level of significance. Two research instruments: Trigonometry Performance Test (TPT) and Trigonometry Achievement Test (TAT) were developed and validated by two experts. The instruments yielded reliability coefficients of 0.70 and 0.81 respectively using split half reliability method to ensure internal consistency of the instruments. Data collected were analyzed using t-test. Findings from the study revealed that there was a significant difference in the achievement scores of students taught using SLS than those taught with CTS. There was significant difference in the retention ability of students taught by SLS has those taught by CTS. Based on the findings, it was recommended among others that the use of spaced learning strategy should be adopted by mathematics teachers and they should be exposed to SLS through seminars, conference and workshops. Keywords: Conventional teaching strategy, Spaced learning strategy, Academic achievement, Retention ability, Trigonometry.
