Abstract: This study examined the use of diagrams and models in biology instruction and their influence on learners’ academic performance in selected secondary schools in Kitwe, Zambia. The research focused on how these visual tools support comprehension of complex biological structures and abstract processes. Guided by its main objective, the study assessed the frequency and manner in which teachers integrate diagrams and models, investigated learners’ attitudes toward them, and evaluated their impact on academic outcomes. Using a descriptive research design, data were collected through questionnaires and interviews with biology teachers and learners. The findings revealed that although diagrams and models are widely recognized as valuable instructional tools, their actual use varies considerably among teachers due to differences in resource availability, pedagogical training, and classroom conditions. Learners expressed highly positive attitudes, noting that these aids simplify complex topics, enhance memory retention, and increase engagement. Analysis of performance data showed notable academic improvement when lessons incorporated well-designed diagrams and models. The study concludes that diagrams and models play a critical role in strengthening learners’ understanding of biological concepts and improving academic performance. Strengthening teachers’ capacity to integrate visual materials, expanding access to teaching resources, and promoting learner-centered strategies could further enhance biology education in Kitwe District. These findings offer valuable insights for educators, curriculum developers, and policymakers seeking to improve science education through effective pedagogical approaches.
