From the information page of Ms. Mercer's Computer Lab Class blog: "This is blog is to support learning on the Internet at our school. You can find assignments for Ms. Mercer’s Computer Lab class, and links to activities and resources.
Goals of this blog are to help you explore the Internet and the themes and subjects you are studying in your classroom. A blog is different than Web pages, because you don’t just read what’s on the blog, but you get to add to the page, by writing comments."
The blog uses slideshare to go over the rules, what a blog is, and information about the Acceptable Use Policy.
