Here is an example of expectations that I had in my classroom as I taught as it specifically pertains to learners blogging.
Keep your details private
No personal information should be included anywhere in the blog. As you post, please use your first initial followed by your last name as a username (ex..hcato). If you are in my Discoveries class, use your assigned screen name.
Conduct
All users should remain respectful. You may not post anything that is rude.
Content
Stay on topic of the discussion and keep your comments school appropriate. This educational blog is not a place to socialize.
All users should be careful and conscious about what they write because blogs are a public place. This means that all writing should be respectful as well as grammatically correct. (Because this is an English related blog, please refrain from using text lingo.)
No plagiarism! Please be sure to give credit where credit is due.
Monitoring
Blog editors have the right to delete any comments posted that are inappropriate or off task. Anyone finding something questionable on the website, please notify the blog editors immediately.
