Impact of Instructional Materials on Students’ Academic Performance in Quantitative Economics in North-West State Colleges of Education, Nigeria

The process of lecturing/teaching especially in tertiary institution in Nigeria demand good instructional material to expand communication gap between the lecturers and the students for effective understanding, but revised is the case. It on these bases the researchers embarked on impact of instructional materials on students’ academic performance in quantitative economics in North-West State Colleges of Education (COE), Nigeria. Four research questions and one hypothesis guided the study. The study adopted an exploratory cross-sectional survey research design. The population of the study consisted of all 8 accredited State COE in North-West Nigeria with 12,320 lecturers and NCE 1 students who registered for quantitative Economics 2019/2020 academic season. The sampled size for the investigation consisted of 1,085 lecturers and students of economics selected from 7 accredited State COE in North -West Nigeria through multi-stage stratified random sampling technique, 35 lecturers and 1,050 students. The researchers developed an instrument for data collection entitled ‘‘Impact of Instructional Materials on Students’ Academic Performance in Quantitative Economics Questionnaire” (IIMSAPQEQ) contained 9 items used for data collection. IIMSAPQEQ was anchored on the 2-point scale from agree and disagree was validated by expert which yielded 0.87 validity index and 0.82 reliability index. Frequency count and percentage were used to answered research questions while parametric statistics was used to test the null hypotheses at 0.05level of significance using SPSS version 23 and the findings revealed that majority of respondents agreed that they don’t always use any instructional materials during lecture period, no supplied of instructional materials available in their school and there is a significant impact of instructional materials on academic performance of students. It was recommended that appropriate measures should be taken by concerned stakeholders of colleges of education to compel all lecturers to use instructional material during lecturing and learning process and supply of instructional material to all colleges of education in Nigeria to minimize students’ poor performance in the subject.
