Although explicitly not intended for public circulation at the time, the fairy-story merits publication for its significance in the history of ...

With large student enrollment, MOOC instructors face the unique challenge in deciding when to intervene in forum discussions with their limited bandwidth. We study this problem of instructor intervention. Using a large sample of forum data culled from 61 courses, we design a binary classifier to predict whether an instructor should intervene in a discussion thread or not. By incorporating novel...

Conversation is central to human interaction. The usual way to conduct asynchronous “conversations” over the Internet is to post e-mail messages on an electronic bulletin board, with messages organized by topic. However, such environments do not allow us to exploit the richness of conversation theory for effective collaboration. This presentation will review key elements of conversation theory ...
