Blogs are a great venue for sharing information and creating a venue for an ongoing dialog. I'd love to see teachers using blogs in this way (the way we do in this "class") with their students. In fact, studies are starting to show that the real power of blogging in the classroom is when a teacher regularly posts questions or content for students to respond to--much like I do here for you.
If I were using a blog with students like this, I'd regularly require participants to go back and revisit earlier thinking as well as comment on the thinking of their peers. I love how this format allows us (and students) to contribute to each others' learning without needing to be in the same room. Of course, teaching students good online communication through commenting on blogs is an added plus. Here's how one teacher does it: Notes from McTeach: Learning to Blog Using Paper. If you're interested in exploring the potential of starting a teacher blog for your students to respond to, let me know--I'd be happy to come by and help you get set up.
Your Assignment
Your job is to go back and revisit at least two previous posts (you'll find links to older posts along the right hand side of this blog), see what folks said, and reply to someone's comment. Or, perhaps you have an update to something you previously posted--now would be a good time to add that to the conversation. When you're done, come back here and post a comment regarding your thoughts about blogging (like this) in the classroom.
