The study examined perception of open educational resources (OERs) by the distance learning students (DLS) of University of Ibadan. Survey research method was adopted for the study; 300 level and 400 level undergraduates‟ of the Distance Learning Centre of University of Ibadan were selected for the study. Questionnaire was the main instrument for data collection. Data collected were analysed using frequency and percentages. The results reveal that majority (37.8%) are matured adults with understanding of Open Educational Resources (OERs) and that without the management and adequate use of OERs by students and teachers for communication and knowledge sharing, achieving sustainable education will be difficult. Digitised projects (20.0%), learning modules (11.1%) and open access journals (11.1%) were the main resources being perceived to be OERs in the institution. The students feel happy using open education resources developed by other universities and institutions (mean=3.33), and also noted that they feel happy sharing OERs with others (mean=3.29). Electronic resources, digitised projects (7, 15.6%), and YouTube (6, 13.3%) were the main resources used to supplement lecture notes, course notes and research work among distance learning students. Challenging factors revealed are lack of institutional support and institutional technology. Training of education personnel in the proper use of technologies for learning and teaching is very germane, therefore, the provision of adequate funding and training of human capital, as well as capacity building, are recommended for the attainment of sustainable education in Nigeria. OERs are indispensable in the bid for sustainable education development hence periodic training and retraining of students and teachers in the use of OERs are also recommended, for enhancing the Nigerian educational system.
