In his introduction to this useful site, psychology professor Jon Mueller presents two arguments. First, he claims that our current educational system fails to teach the need for critical skills for success in the 21st century. Second, he posits that the reason for this is, at least partially, due to confusion about how to assess those skills. The website is an answer to that confusion. Here educators will find Mueller's program of Authentic Assessment. Readers may like to begin with the first three sections of the site, "What is it?," "Why do it?," and "How do you do it," before moving onto sections that explain such topics as Standards, Rubrics, and Tasks. Throughout the site, Mueller makes a genuine attempt to provide both a philosophical backdrop for his assessment techniques and the sorts of down-to-earth tools that educators can easily use in their classrooms.
