I love this recent blog post about group work and gifted kids:

Unfortunately, I think that in the average classroom, the gifted kiddos are often split up among groups, and are forced into what becomes a very frustrating experience. Teachers need to have a better understanding of how this impacts a gifted student, their "group experience," and their behavior within the group (I have received little sense that they do, or that they consider this, although I distinctly recall HATING group projects in elementary, for the very same reasons listed in the blog post). Some kiddos are more willing to, um, hide their true feelings and/or frustrations about the group experience than others (my DD has NOT always hidden her frustration)...
