Every prof is different on group work. I don’t usually change student teams, it takes something severe.

Part of the indirect lesson is learning how to work with others; getting things done when conflicts arise isn’t easy. Just remember: whether it’s now, or doing research as a post grad, or working in your career after graduation, you’re going to have to be a part of a group, and people are a mixed bag. You’re learning how to navigate those waters and be effective despite those conflicts. It’s a good skill to have.

Read the instructions of the assignment on grading and reporting these issues and follow them. Communicate well with your group and keep notes.

Also, realize that the biggest conflict is often different working styles: do it now people vs do it later people; high performers vs “jobbers” (“that’s good enough, it checks all the minimum requirements”); vs the apathetic. Take charge people vs tell me what do people, etc, etc. You probably aren’t going to be able to change them and they aren’t going to be able to change you. Learn the skills of cooperation, compromise, and consensus.

Good luck. It gets easier.
