This research work investigated the influence of instructional materials (teaching aids) on
students’ academic performance in senior secondary school Chemistry in Cross River State. A two
group pre-test post test quasi-experimental design was adopted for the study. One research question
and one hypothesis were formulated to guide the study. A total of 100 senior secondary one (SS1)
Chemistry students were selected from five (5) Schools in Yakuur Local Government Area of Cross
River State through simple random sampling and stratified random sampling techniques. Fifty SSI
students (Experimental group) were taught with instructional materials and another forty (Control group)
were taught without instructional materials. A validated Chemistry Achievement Test (CAT) was used to
gather data for the study and a split-half was carried out using the Pearson product moment correlation
to obtain a reliability coefficient of 0.67.Independent t-test was used to test the hypothesis at 0.05
significant level while the Pearson product moment correlation coefficient at that level was used to
analyse the research questions. The study revealed that students taught with instructional materials
performed significantly better than those taught without instructional materials and also that the use of
instructional materials generally improved students’ understanding of concepts and led to high
academic achievements . Recommendations were made on how to improve academic performance of
chemistry students by encouraging the use of instructional materials in teaching-learning chemistry.
