The web page linked above uses a table to compare features of blogs, wikis, and Google Docs. Comparison topics include definitions, number of concurrent authors, and how each tool is used in collaborative activities. The author, who is unknown, outlines commonly known strengths and weaknesses of each tool. For example, one of the advantages of using a wiki is that a previous revision can be reverted to at any time. An example of a wiki disadvantage is that a user can accidentally override a fellow collaborator’s contribution if the wiki is used as a synchronous tool. Teachers can use this web page to help decide if one of these tools might be appropriate for a lesson that integrates technology. While all three tools can be used for reflection, blogs are probably most commonly associated with reflective activities. The table includes links to several blogs focused on reflective practice including David Warlick’s blog.
