This study investigated the “Effects of Video Clip Instructional Strategy on Students’ Interest and Achievement in Ecology in Abuja, Nigeria.” The study adopted quasi-experimental research of pre-test, post-test, non-equivalent, non-randomized, control group design. The population for the study consists of 35,155 (15,767 males and females) SS students. Purposive and simple random sampling techniques was used in the three stages to sample 145 students, (80 males and 65 females); students were selected for the study. Two instruments, namely Ecology Achievement Test (EAT) and Ecology Retention Test (ERT), were was validated and found reliable for study. Four research questions were raised, and four null hypotheses were formulated for the study. Descriptive statistics of mean and standard deviation were used to answer research questions, while inferential statistics of ANCOVA was used to test the null hypotheses at 0.05 level of significant. The findings revealed that there is significant difference between the achievement and retention of students exposed to Video Clip Instructional strategy and their counterpart exposed to the conventional method in favor of the experimental group. Also, the findings revealed that there is no significant difference between male and female students’ achievement and retention in ecology using the video clip instructional strategy. Hence the researcher recommended that the use of Video clip instructional strategy should be adopted for teaching of Ecology concepts in the secondary schools and in-service training program for Biology Teachers, in the form of workshops, seminars and conferences, should be organized to focus more on how to use video clip instructional strategy in teaching ecology concepts, among others.
