I've been trying---more or less in vain this year---to get a class blog going for my APers. The major frustration and roadblock has been that the district filter doesn't allow blogs to pass through. That makes it pretty hard to get student involvement.
The Chicago Tribune recently published a piece on the growth of blogs in the classroom. It highlights some of the positive results students and teachers are experiencing...and shows off some of the potential for using this as a classroom tool.
The article doesn't focus much on some of the potential dangers in using blogs with students, such as the possibility of on-line predators. I don't know that there will ever be a foolproof sort of system, which is what my district is after. I wish we could provide students and parents with guarantees that their kids will never be in any harm's way, but Life just doesn't work like that. We just have to do the best we can to protect students and then educate them about protecting themselves.
I wish that I had had different results this year. Maybe I just need to focus on the bigger picture instead. By starting this in my district, I've opened the door to possibility for others. The future may hold lots of blogs for students and teachers. I am looking forward to that.
