5.1.3 Reading: The Visualization of Discussion Interactions in this Course

Since more discussion threads are yet to be contributed in this course, and a few course participants provided replies to peer thread, instead of examining discussion interaction among course participants, we built a two-mode or bipartite network diagram to examine the links between discussion topics and participants.

  • The grey squares represent four discussion topics: CE = Content Engagement, CD = Content Design, DP = Discussion Participation, QS = Quiz Submissions
  • Each blue icon represents a participant who posted at least one thread to a discussion topic.
In some cases, a static network diagram can present mass interaction better than what a dynamic interactive graph does. Therefore, we also include a two-mode static network graph that was built in R using igraph Links to an external site. package.
  • The blue squares represent four discussion topics: CE = Content Engagement, CD = Content Design, DP = Discussion Participation, QS = Quiz Submissions
  • Each orange circle represents a student who posted at least one thread to a discussion topic.
  • The width of a line indicates the length of a discussion thread posted by a student to a discussion topic.
