A descriptive analysis was used to analyze the obtained data, which were then presented in frequencies and percentages in tables. Findings indicate that the sampled lecturers from the higher learning institutions are moderately aware of the OERs. Regarding the feelings of lecturers over the use of OER, the collected data have revealed that a majority of the lecturers believed in OERs, are happy for those who adopt their OERs, and that they feel that OERs enhance the reputation of their institutions. In terms of lecturers' attitudes toward OERs, a majority of the lecturers strongly agreed that OERs are more beneficial to the academic and research communities.
