<p>I think I would contact the student and ask if everything is okay. The first thing I would want to do is clarify her actions so that I can make a informed decision of how to handle her actions or any similar actions in the future. You might want to create some dialect with the students in how they feel about groups. My daughter is constantly complaining about the people and how they work within the group and how the teachers are unwilling to listen to concerns or complaints. I would set some rules after having the conversation with the group and have scheduled appointment to see how the participation is panning out.</p>
