One of the biggest challenges my students seem to be facing is group work. Most seem to understand how to do the group work, but the problem is that there are some students who either aren't participating at all in their group or are only participating in a minimal capacity. This causes the students who are handling most of the work to become nervous about their grade and resentful toward the non-participating students. I know a lot of instructors base their grade on the group as a whole, but I don't feel that the hardworking students should lose points because some of their fellow group members are slacking off. However, that does add more difficulty to the grading process. Any thoughts?
