Instructional Materials, Academic Performance, Junior Secondary School Students, Teaching Resources, Student Learning,

This study was carried out to study the instructional material and student academic performance in public junior secondary school in Egor local government area of Edo state. To therefore achieve the objectives of the study three (3) research questions were raised. A descriptive survey research design was used for the study. The study population comprises all students of public junior secondary schools in Egor Local Government Area of Edo State. The total number of students in public junior secondary schools in Egor Local Government Area is 12,000 students, based on the statistics provided by the State Universal Basic Education Board (SUBEB). The sample of this study comprised 100 junior secondary school students, selected from 10 secondary schools out of the 12 public juniour secondary schools in Egor Local Government Area, Edo State. The instrument used for data collection in this study was the “Instructional Materials and Students’ Academic Performance Questionnaire” (IMSAPQ). The validity of the questionnaire was established by the researcher’s supervisor and two other experts in the Department of Educational Management. The observations, opinions, suggestions, and corrections made by these experts were incorporated into the final version of the instrument, ensuring that it accurately measures the intended constructs. To determine the reliability of the instrument, the test-retest procedure was adopted. Thereafter, their responses on the two occasions was collated and correlated to determine its correlation coefficient using Pearson product movement correlation statistics the instruments yielded a coefficient value of 0.72 which shows that the instrument was reliable. Based on the findings, it can be concluded that instructional materials significantly enhance the academic performance of students in public junior secondary schools in the Egor Local Government Area of Edo State. While overall academic performance is high, there is a notable gap in English performance in certain schools, which points to an area requiring focused improvement. The use of varied instructional materials, including visual, digital, and audio-visual resources, is linked to improved student engagement, understanding, and retention. However, the discrepancies in performance across schools highlight the need for targeted interventions, particularly in schools where English language performance lags behind. Based on the findings, it is recommended that: Government and Educational Authorities should invest in providing schools with a more consistent supply of instructional materials, including digital and visual resources, to ensure all students have access to high-quality learning tools. Teachers should receive regular professional development opportunities to enhance their proficiency in using instructional materials effectively, with a focus on integrating digital and multimedia tools into their teaching strategies
