I'm currently analyzing a past MOOC that we ran on EdX.org. In this MOOC, we had manually specified cohorts (we uploaded CSV files with student IDs), and a number of forum discussions (linked to lecture content) that were segmented by cohort. Currently, we are looking at doing some analysis comparing the participation and discussion characteristics of different cohorts. I have been looking at the data in the forum mongo dump, which has DiscussionThreads and Comments, however I cannot find any metadata about which cohort a given comment belongs to? I guess I could extract all the comments, and lookup which cohort a student was in, and segment manually, but it seems strange to me that this data wouldn't be captured somewhere? Surely the system is not going through a long thread, and looking up the cohort-status of every single member who has posted there, to determine what to show every time a user pulls up a thread?
I even tried browsing through the code, and there seemed to be something about cohorts and group_id, however there is no group_id in the mongo data, and anyway I got quite lost in all the code.
