The study investigated learners’ perception on quality of instructional materials and preferences for various formats at the National Open University of Nigeria. It also examined the extent of availability and affordability of the instructional materials. The research design adopted for the study was a descriptive research of the survey type. The population of the study consisted of all learners in the National Open University of Nigeria. Purposive, stratified and simple random sampling technique was used in selecting the sample for this study. A self-designed questionnaire tagged “students’ Feedback on Instructional Material Questionnaire” served as the research instrument. Split half test was used to test the reliability and the reliability coefficient of 0.8 obtained was considered good enough to be used for the study. Six research questions were generated while one hypothesis was tested. The result of data analysis indicated learners’ acceptance of physical appearance of the instructional materials except in the area of structure. The study also revealed learners’ preference for print mode while instructional materials were found unaffordable and not readily available to the learners. Based on the findings of this study, it was recommended that instructional materials must be revised to make it more interactive and made readily available and affordable to learners.
