Classroom blogs

If you're wanting to setup a classroom blog, here are a few mistakes many teachers make when creating one (this list is according to Richard Byrne's blog, Free Technology for Teachers):

1. Making it optional -- few students will do it if it's optional and parents won't buy in
2. Inconsistency -- start small, like one post a week, and be consistent with the expectations
3. Lack of purpose -- have a reasons for your students to blog (example: weekly learning reflections)
4. Running before walking -- set realistic blogging goals for your students like once a week
5. Creating too many blogs too soon
