This study investigated the effect of Collaborative Concept Mapping Instructional Strategy (CCMIS) on secondary school students’ achievement in light waves. A sample of 105 students from a population of 1,828 SS2 physics students in Abuja Municipal Area Council was used for the study. Quasi-experimental research design, consisting of pre-test, post-test and retention test was employed for the study. The design involved two groups: experimental group that was taught using CCMIS and control group that was exposed to conventional method. Two research questions raised for the study were answered using mean and standard deviation while the two hypotheses formulated were tested using ANCOVA at 0.05 level of significant. The instrument used for data collection was Light Waves Achievement Test (LWAT). A validity index of 0.85 and a reliability coefficient of 0.76 were respectively obtained for LWAT. Students in both groups were given pre-test before instruction. During the instruction, the concept of light waves was taught in the two groups for a period of five weeks and thereafter a post-achievement test was administered. The findings of the study revealed among others, that the group taught using CCMIS significantly scored higher in the post-test than the group exposed to conventional method. This is evidence in H01, F(1,102) = 86.766 and P = 0.000 < ∝ = 0.05. The results also showed that gender has no significant influence on mean achievement of students taught light waves using CCMIS as revealed in H02, F(1,49) = 0.676 and p = 0.415 > ∝ = 0.05. The findings imply that CCMIS is superior to the conventional method in enhancing students’ achievement in light waves and gender has no significant influence on students’ achievement in light waves when exposed to CCMIS. The recommendation made, among others was that CCMIS should be adopted in the teaching and learning of light waves in secondary schools in Abuja, Nigeria.
