As of right now when implementing the standard group feature into an assignment a group has to consist of at least two members. This problem could arise with an uneven number of students in the class or a student joining the class later in the semester and they have to choose one group which have a specific topic. The solution to this problem is fairly simple: Make groups within assignments in Canvas be able to consist of only one member if desired.

We would use the one-man group to do projects, bachelor thesis or master thesis, assignments you have to do at home, for DOI with scientific studies or just for one person presentation where every student gets his own topic. In all this examples we would use the self sign-up option.
