Our first group of Classroom Learning 2.0 explorers dwindled from 31 down to 15 or so, but those who persevered all seemed to enjoy it and found things they believe they will use. (In all fairness, those who were unable to finish had valid reasons.) Reading their blogs allowed me to get to know sides of them that I had not seen before and, in some cases, had not expected to see.
A new group has now begun the journey. We're running into some issues with posting comments but I have confidence that either we'll figure it out or it will turn out to be a Blogger problem and they'll fix it. I hope so, since interaction between the members of the group can be both helpful and just plain fun.
