PUBLIC SECONDARY SCHOOLS

The availability and use of instructional materials are essential for improving the teaching and learning of Biology in secondary schools. This study investigated the availability and use of instructional materials in teaching Biology in public secondary schools in Oredo Local Government Area of Edo State. The research examined the extent to which instructional materials are available, the types of instructional materials that are available, the challenges affecting their effective use and how it affects students' academic performance. A descriptive survey design was adopted, and data were collected from forty (40) Biology teachers using a structured questionnaire. The data obtained were analyzed using frequency counts and percentages. The results revealed that although some instructional materials such as charts, models, and specimens were available, many vital materials including laboratory equipment and audiovisual aids were inadequate. Findings also showed that teachers use available instructional materials moderately due to factors such as lack of funds, poor maintenance, lack of trained teachers and overcrowded classrooms. The study concludes that instructional materials greatly enhance effective teaching and learning of Biology, but their inadequate availability and inconsistent use limit students’ understanding of biological concepts. It recommends that the government and school administrators should provide adequate instructional materials, train teachers on their effective use, and ensure regular supervision to promote improved Biology teaching and learning outcomes
