"With the advent of the World Wide Web and the huge amount of information that is contained there, students need to be able to critically evaluate a Web page for authenticity, applicability, authorship, bias, and usability. The ability to critically evaluate information is an important skill in this information age. To help you get started with this process with your students, I have designed a series of evaluation surveys, one each at the elementary, middle, and secondary school levels. The elementary, middle, and secondary surveys have been re-designed and updated in February of 2009. The virtual tour, blog, podcast, and teacher site evaluations have been added since 2005 and updated in 2009."
