Effects of Inquiry-Based Laboratory Instruction on Senior Secondary Students' Achievement in Chemistry
Ngozi A. Eze, Chidiebere Nwachukwu
This quasi-experimental study examined the effect of inquiry-based laboratory instruction on the academic achievement of senior secondary school students in chemistry. A sample of 214 SS2 students drawn from six secondary schools in Enugu State was assigned to experimental and control groups. Students taught using the inquiry-based approach achieved significantly higher post-test scores than those taught by conventional demonstration methods, and the effect was more pronounced among female students. The findings support wider adoption of guided inquiry in Nigerian chemistry laboratories, even where equipment is limited.
