In MATH342 and MATH440, for which homeworks don't carry CA credit, Toby Hall allowed students to submit homework in groups of any size of their choice. This seemed to encourage students to work together and discuss the module contents, and it also reduced the marking burden. Around half of students who submitted work did so in groups, with group sizes mostly between 2 and 4 students.
Toby made colour photocopies of each piece of marked work so that each student in the group would get the same feedback. This was much less time-consuming than marking individual submissions.
