We are seeing it too. We've had multiple group presentations that they work on via google docs. Luckily, DD has been able to pick her group and avoid having slackers on her team. I do see value in DD not always getting everything presented her way and having to compromise with co-workers.

That said, I would feel differently if DD got stuck with a bunch of kids who wouldn't contribute (a constant problem in elementary). In the past, DD would just take over the project so she wouldn't be penalized for being stuck with lazy kids. It infuriated her. DD mentioned another team had a kid who did not participate at all on a certain project because her family took off for a week to Disneyworld. I don't know how the teacher justified treating that kid the same way. Maybe she was supposed to contribute remotely while waiting in line for Space Mountain?!
