I have been asked in the past to provide key questions that a district and teachers could use to vet a website. While all websites designated for class use should be previewed by the teacher, it is especially important that Web 2.0 sites go through a vetting process. While everyone may have a different definition of Web 2.0, I promote the idea that a Web 2.0 site is a site that allows for interactivity. In this interactivity, a user may be able communicate and interact with others, leave a digital footprint, store digital information, and be open to various outside sources. For this reason it is important to vet a Web 2.0 site before providing access to students.
