Like many professors, I use group projects in my classes. When my students work together on a project, I'm hoping they'll be able to accomplish complex instructional tasks and support each other's learning on the project and in the course. In my experience, I've found that many student groups function positively and productively, but there are always some groups that do not. In those groups infighting occurs, which negatively affects the students' work in addition to their learning, their connection to course content, and their overall impression of the class.
