Blogging in science class

    I read an article on techlearning about using blogs in
    science class (or any class for that matter).;jsessionid=1OOOFFADFYBQQQSNDBCCKH0CJUMEKJVN?articleID=164302317Has anyone used blogs in their classes? Do you have
    posted/published rules that the students follow regarding
    the content and format of their posts? Do you require
    students to post comments on the blog?

    I set up a test blog at

    I want to use it with my classes to solicit their opinions
    on science class activities, topics and content. I also
    want to support writing skills, technology skills and foster
    some critical thinking.
