Abstract
This study investigated the influence of instructional materials on academic performance of students in biology in senior secondary schools in Abi local Government Area of Cross River State. The study was guided by a null hypothesis which was tested at .05 level of significance. Literature review was done based on the variables of the study. Ex-post facto design was adopted for the study. A sample of 200 respondents was randomly selected from ten (10) selected senior secondary schools. The selection was done through the application of stratified random sampling technique. The questionnaire was the main instrument adopted for data collection. The data collected were coded, scored and analyzed using independent t-test analysis. The results of the analysis indicate that the values of instructional materials in teaching significantly influence students’ academic performance in biology. Based on the findings, it was recommended that adequate instructional material should be provided and appropriate supervision should be carried out by the school authority and the ministry of education to enhance students’ academic performance in biology.
