Based on a framework developed for investigating learners’ interaction with online content in Wawasan Open University, data from the LMS log and activity database was extracted. The data is then analyzed based on the pattern and behavior of learners’ interaction with the online content of the courses. Further analysis is done by transcribing the discussions and exchanges of teacher and learners within the online forums, specifically investigating the dimension, depth and category of exchanges that occurred. Based on the findings, several recommendations are made to enhance the design and delivery of web-based content, aiming at maximizing the efficacy of the online learning environment of undergraduate and postgraduate courses in open distance learning (ODL).
