Asynchronous communication by means of discussion forums plays an essential role in supporting collaborative learning. Online forums allow learners to ask questions, express their thoughts, share resources, and justify their opinions beyond the four walls of the classroom. Proponents of collaborative learning claim that this type of learning can lead to enhanced educational outcomes for students. This article examines data from an online discussion forum involving a group of students from Malaysia and the Middle East, who are working toward master's degrees at a tertiary institution in Malaysia. The purpose of the study is to understand how the students interact and collaborate in the process of learning topics that had previously been discussed in a face-to-face mode. The findings identify collaborative learning behavior among the students, including contributing, exploring, providing information, and giving feedback. Additional findings indicate that even with minimal intervention from the lecturer, the students participated actively in the online forum. (Contains 1 figure and 6 tables.)
