We have a question that has attracted a few close votes. I don't know all the voters' reasons for that, but one comment suggests one possibility:
Nothing about your question seems specific to CS. Could you rewrite it?
I think we have a chance here to choose where we draw the line. The subject of this site is two-fold: Computer Science, and Educators. An issue that relates to the classroom may not be purely a Computer Science problem. Likewise a Computer Science problem may not purely an Educators' issue. I'm thinking that if it impacts the classroom of a CS instructor, it's probably on-topic here, whether or not it could also apply to other classrooms. How to assign and grade group projects applies to a Creative Writing class where there is a group assignment, or to a Biology class where there are group lab experiments. How to deal with the problem might be different in a CS class than a Biology class, however.
For the question at hand, solutions can utilize CS-style objectives that are not available to other disciplines. Not that they have to use such tools, just that they can.
My view is that this question should be kept, and that other questions that are not restricted to CS issues, but that can be experienced in the CS classroom, should be kept.
Too broad is still an option, although I don't feel that it applies to this question.
