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.

Assessment Literacy Among Secondary School Biology Teachers in Enugu State: A Mixed-Methods Study

Obinna Anyanwu, Amina Bello

Classroom assessment shapes what students ultimately learn, yet teacher assessment literacy remains under-examined in Nigerian secondary education. This mixed-methods study surveyed 178 biology teachers and conducted follow-up interviews with 22 of them. While teachers reported confidence in constructing objective tests, analysis of their instruments revealed heavy reliance on recall-level items and limited use of formative feedback. The paper proposes a school-based professional development model targeted at assessment design.

Competency-Based Curriculum Reform in Nigerian Secondary Science: Policy Intent and Classroom Reality

Ifeoma Ugwu

Nigeria's shift toward competency-based curricula promises learner-centred science instruction, but implementation depends on what teachers actually do. Drawing on classroom observation in 30 schools and document analysis of curriculum guides, this study finds a persistent gap between stated competency outcomes and examination-driven classroom practice. The paper identifies assessment reform as the binding constraint on curriculum change.

Gender Participation in STEM Enrolment Across South-East Nigeria: A Five-Year Trend Analysis

Amina Bello, Ifeoma Ugwu

Using enrolment records from 2019 to 2024 across five south-eastern states, this study traces gender participation patterns in senior secondary science streams. Female enrolment in biology consistently exceeded male enrolment, while physics and further mathematics remained strongly male-dominated. The analysis links subject-level disparities to career guidance practice rather than measured ability differences.
