E; Alabi, EThe study investigated the effects of the investigative laboratory approach and the expository method on science process skills acquisition by chemistry students. The design of the study was a pre-test post-test control group quasi-experimental design. The sample consisted of one hundred and twenty students from senior secondary schools in OndoState, Nigeria. Two research hypotheses guided the study. Treatment consisted of teaching selected chemistry concepts to the experimental group using investigative laboratory approach while the other group was taught using the expository method. Test of science process skill acquisition (TOSPSA) and chemistry achievement test (CAT) were the instruments used for data collection. Mean and standard deviation and also T-test were used to test the hypotheses at 0.05 level of significance. Results revealed that students taught using the investigative laboratory approach performed significantly better than those taught using the expository method. Base on the findings of this study, the use of investigative laboratory approach to enhance science process skills acquisition in chemistry students was recommended
