The study investigated the effect of teachers’ instructional techniques on students’ achievement and retention in Chemistry in senior secondary schools in Ondo State, Nigeria. The study also determined the effects of the instructional technique on gender achievement in Chemistry. A quasi-experimental design was adopted for the study. The sample for the study consisted of 240 Senior Secondary School Two (SSS II) Chemistry students selected in stages using simple random sampling techniques. Six science intact classes from six senior secondary schools were selected from three senatorial districts in Ondo State. Four formed the experimental class while two formed the control group. The students in the experimental group were exposed to Computer Assisted Instruction (CAI) while the control groups were taught with the conventional teaching method. Chemistry Achievement Test (CAT) was used to collect relevant data for this study. The experimental group was treated using CAI package while the control group was treated using conventional classroom teaching. t-test, ANCOVA (Analysis of Co-Variance) and Multiple Classification Analysis (MCA) were used to test the research hypotheses at a 0.05 level of significance. The result from the study showed that the achievement of students in the experimental group was better than those of their counterparts in the control group, students in the experimental group also retain better than their counterparts in the control group and that gender did not have a significant effect on the retention ability of the experimental group. Based on the findings of the study, it was recommended that the potential of CAI should be utilised to enhance better achievement and retention of students in Chemistry. There should be regular training and re-training of Chemistry teachers on the use of computers so as to improve the method of teaching the subject and the government should establish a CAI promotion department to plan, organise and coordinate efforts to develop and utilise CAI softwares.
