Abstract: The study investigated the effect of 2 programmed instructional strategies on students’ performance in chemistry. The study focused specifically on the effect of Computer Assisted Instruction (CAI) and video-tape Mediated Instruction (VMI) (over the conventional methods) on the teaching of chemistry in Nigerian Secondary Schools. A quasi-experimental design using a pre-test, post-test 3 groups was employed for the study. The sample consisted of 60 Chemistry students randomly selected from public secondary schools in Lagos State, Nigeria. Two Null hypotheses were raised for the study and tested using One-way ANOVA. The study revealed the homogeneity of the three groups through pre-test performance prior to treatment. The study also showed that both the Computer Assisted Instruction (CAI) and Video-tape Mediated Instruction (VMI) have positive effect on students performance than the conventional method of teaching which was employed as control. The use of CAI and VMI was recommended for teaching chemistry in Nigeria secondary schools.
