Sažetak

This study examined the effect of hands-on nanoscience activities on senior secondary school students’ performance in chemistry, specifically on the concept of rate of reaction. A quasi-experimental, non-equivalent, pre-test–post-test control group design with a 2 × 2 × 3 factorial framework was employed. The sample comprised 127 SS II students from two co-educational schools in Ilorin, divided into experimental (n = 62) and control (n = 65) groups. Data were collected using a validated 50-item Rate of Reaction Performance Test (RRPT) and analysed with ANCOVA at the 0.05 significance level. Findings revealed a significant main effect of instructional strategy on students’ performance (F(1, 126) = 24.62, p < .05), indicating that students taught with hands-on nanoscience activities significantly outperformed those taught with conventional methods. Achievement level also showed a significant effect (F(2, 126) = 18.47, p < .05), with high achievers outperforming medium and low achievers, while medium achievers outperformed low achievers. However, gender and the interaction of gender and achievement level were not significant. These findings highlight the effectiveness of hands-on nanoscience activities in promoting students’ conceptual understanding, with implications for adopting innovative strategies that foster equitable and differentiated learning in chemistry classrooms.
