The discussion log of chapter 17 of Learning Analytics Methods and
Tutorials (Saqr, 2024), one row per post in the Digital Learning
Transition MOOC, April to June 2013. A post names the participant who
wrote it and the participant it answers, so a tie runs from sender to
receiver; discussion is the thread the post belongs to, which is what
makes the log threaded in the sense dynet() means by thread =.
Format
A data frame with 2529 rows and 4 columns:
- sender
Character. The participant who wrote the post.
- receiver
Character. The participant the post answers.
- timestamp
POSIXct (UTC). When the post was made, from 2013-04-04 16:32 to 2013-06-16 17:12.
- discussion
Character. Thread title; 338 distinct threads.
