How to make group work work? Occasionally I have some material to cover that is best presented in the form of take-home group projects.

Some student groups manage to find a way to coordinate their work well and to complete the projects successfully, with every team member benefiting from the collaboration. Other groups do not do so well:


Some groups evenly divide the work, but still work in isolation, losing the benefits of working with peers.
Some groups push the work to one or two students, while the remaining students merely contribute their name.


I wonder if there are strategies or tools instructors use that can encourage more groups to operate successfully while they are working outside of class?
I think first it may be worthwhile to accept that in any group work situation there is the possibility that people will worked siloed (or isolated from one another) or one or two people will push the work forward while others are relegated or chose to remain in a passive state.

There are some good reasons for this. I recall being a student with a pretty solid GPA, group projects were a horror for me. If the project grade is based on the overall project and does not take into account individual contributions this meant that students who were less focused on their GPA would be willing to turn in something that was not up to my standards. This led both to situations where other students refused to do work on the project (knowing that the stronger students would carry them in order to avoid dings to their GPA) and to situations where stronger students would freeze out other students (ie the stronger students would choose to take all the work and not let other be involved) in order to maintain control over the project.

Group projects are often used as an analogy for working in the 'real world' where working in groups is the norm. The fundamental difference is that in most cases if a peer is completely slacking or sending in subpar work there is a concrete structure to monitor and handle that issue (which doesn't always work of course but there's almost always more accountability than in academic group projects). You can mimic this behavior in an academic setting by splitting up the grades for the project. Don't give one 'group grade' to everyone, instead have students report on who did what (this is particularly effective if you can have them set this early in the project instead of during turn-in) and correlate the students grade to both their work and their work in the context of the project. Having this set up early can be a great way of preventing aggressive or strong students from freezing out what are perceived as the 'weak links'.

Additionally consider regular checkpoints on the project. This will let you get a feel for the interactions in the group and the content being produced while also minimizing the opportunity for a student to jeopardize the group by waiting until the last minute to work on their part (this will still happen to some extent).

In short - add more structure to the group project. This increases the workload on your end but it mitigates the most common issues you'll see in groups during group projects.
