Teacher and class blogs are very useful tools for several reasons. Teachers can post not only assignments and homework, but also discussion questions. Students can respond by posting comments to the teacher's post. There are at least two pedagogical advantages to this type of discussion. One is that students are writing, not just speaking. The second is that everyone can participate.
Too often, class discussions are dominated by a handful of students who do all the talking while others never speak up at all. Using a blog discussion forum enables every student to contribute. Furthermore, they can respond to each other, which leads to many possibilities for constructive peer criticism.
Blogs are quick and easy. Comment moderation requires little time on your part, and is a 100% effective way of keeping inappropriate comments off your blog.
Furthermore, you can easily add links to many useful resources specific to your subject. You can add files, pictures, and media to your blogs.
