Improvised Laboratory Materials and Practical Skill Acquisition in Under-Resourced Secondary Schools

Samuel O. Adeyemi, Ngozi A. Eze

Chronic equipment shortages limit practical science across much of sub-Saharan Africa. This study evaluated a structured improvisation programme in which teachers built laboratory apparatus from locally available materials. Across twelve schools, students in improvisation classrooms demonstrated practical skill gains statistically indistinguishable from those in fully equipped comparison schools, at a fraction of the cost. The study argues that improvisation should be treated as a legitimate pedagogical competence rather than a stopgap.

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.

Rethinking Practical Work in African Science Classrooms

Chidiebere Nwachukwu

This editorial introduces the special issue on laboratory practice in under-resourced schools and argues that the field has too often imported assumptions about practical work from well-equipped Northern contexts without examining their fit.
