I just visited Edublogs.org to look for an introductory video for my learners on how to blog. Then I found this list on using the blog for teaching your students:
1. Post materials and resources
2. Host online discussions
3. Create a class publication
4. Replace your newsletter
5. Get your students blogging
6. Share your lesson plans
7. Integrate multimedia of all descriptions
8. Organise, organise, organise
9. Get feedback
10. Create a fully functional website
May I lift this whole section from the posting, as I find it speaks a lot of truth:
One of the great things about Edublogs are that they are much, much more than just blogging tools. In fact, you can use your edublog to create a multi-layered, in-depth, multimedia rich website – that hardly looks like a blog at all. So, if you’d rather create a set of static content, archive of important information or even index for your library – you can bend an Edublog to suit your needs.
These are good tips for teachers; especially those that are new to blogging.
