In Brightspace you can create groups where students can enrol themselves this a great for student project groups as students can decide which group they want to join. You can also limit the number of groups and the number of students in each group.
To find out how to create self-enrolment groups watch the video below.
Now that you know about self-enrolment groups – have a go yourself!
Please note: All information is accurate at the time of posting but the Brightspace / Teams layout may have updated.
For more help or information on this tool, check out the iPark website for handy how-to guides; or Brightspace Bytes on Brightspace for helpful screencast tutorials.
You are able to add new groups to a group category, but you are not able to change the size maximum number of students in a group of the groups. Therefore you have to keep in mind how big the groups need to be when creating them. Note that this only concerns the standard group size Brightspace assigns to groups; you are able to add more students manually, even if maximum capacity has been reached.
