Example of a class/school blog

A blog-shorthand for "Web log"-is an online collection of personal commentary and links. Blogs can be viewed as online journals to which others can respond that are as simple to use as e-mail. The simplicity of creating and maintaining blogs means they can rapidly lead to open discussions. Faculty are using blogs to express their opinions, promote dialogue in their disciplines, and support teaching and learning; students increasingly use blogs for personal expression and as course requirements.

Structured exercises and clear goals are further enhancing the educational value of blogs. Put into practice with an understanding of their benefits and limitations, blogs are an increasingly accepted instructional technology tool.
