Massively Open Online Courses (MOOCs) have gained attention recently because of their great potential to reach learners. Substantial empirical study has focused on student persistence and their interactions with the course materials. However, most MOOCs include a rich textual dialogue forum, and these textual interactions are largely unexplored. Automatically understanding the nature of discussion forum posts holds great promise for providing adaptive support to individual students and to collaborative groups. This paper presents a study that applies unsupervised student understanding models originally developed for synchronous tutorial dialogue to MOOC forums. We use a clustering approach to group similar posts, compare the clusters with manual annotations by MOOC researchers, and further investigate clusters qualitatively. This paper constitutes a step toward applying unsupervised models to asynchronous communication, which can enable massive-scale automated discourse analysis and mining to better support students' learning.
