I'm experimenting with using a blog to encourage independent learning with my KS5 students. I post an article each week. As a homework task, the students have to comment on the article with their own view. They also have the opportunity to comment on each others' views. The depth of argument that develops is excellent. If anyone else here has used a blog to help teach, I would love to hear how you use it, how effective it has been, etc. Also, before anybody starts worrying about the abuse of online media, the blog is monitored, comments must be approved by me before they appear and there is no feature allowing any secretive messaging, etc.
