Ways that a Blog can be used are:
~~ To post up-to-date News
~~ As a Reflection during a particular project
~~ To Share Content with individuals/students in a group
~~ As a Virtual Journal
...a place to gather, share, and learn.
Does that Mean All the Time?
Does that mean that I have to communicate with students at all hours of the day and night?
No, you should let students know WHEN you will post answers, comments, or suggestions; but they will be able to post to the blog 24/7. So, remember if you want something done you will have to specify not only the date but the time also.
