Chemistry has long been regarded as one of the cornerstone sciences upon which industrial growth, medicine, agriculture, and modern technology rest (Shamsuddin, Arome, Aminu, Isah, & Adamu, 2017). Yet in many Nigerian classrooms, learners continue to record disappointing achievement in the subject, a pattern that researchers have persistently linked to an over-reliance on teacher-centred, expository instruction rather than activity-based approaches (Ekpo & Mfam, 2025). This paper adopts a conceptual, library-based approach to examine seven commonly used chemistry teaching methods — lecture, demonstration, laboratory/practical, problem-based learning, inquiry/discovery, cooperative learning, and computer/ICT-assisted instruction — with a view to determining which offers the greatest yield for technological advancement. Anchored on constructivist and experiential learning theories (Piaget, 1970; Vygotsky, 1978; Bruner, 1961; Dewey, 1938; Ausubel, 1968), the paper argues that no single method is sufficient in isolation. Rather, an integrated, activity-based approach that combines structured laboratory practice with cooperative grouping and computer-assisted simulation, periodically anchored in authentic problems, consistently produces superior achievement, stronger retention, and deeper problem solving competence than the conventional lecture method. It is this integrated approach, rather than any single strategy applied alone, that is best positioned to produce the critical thinkers, innovators, and technically skilled manpower that Nigeria requires for technological advancement. The paper recommends sustained funding and equipping of school laboratories, regular in-service training of chemistry teachers in activity-based pedagogy, and the deliberate integration of information and communication technology into the chemistry curriculum.
