First year University undergraduates are not only faced with challenges to cope with the complexities of University systems but of geographical separation between them and teachers which characterized by distance education. Therefore, the need for learner support services with modern day technology innovations. This study examined first year undergraduates’ experience in the use of OER while interacting on the learning management system (LMS) platform in selected Physics courses. Questionnaire with a reliability coefficient of 0.85 using Cronbach’s Alpha was used for data collection and analysed using diffusion theory of innovation. A total number of 71 University undergraduates participated in the study while facilitators introduce them to the use of OER. The results showed that OER was able to improve undergraduate’s perception and attitude towards learning Physics and its use in other subjects should be encouraged. // Paper ID 424
