Imagine your third grade class is ready to begin a unit on persuasive writing.  You have your students get with their partner and sign onto the Internet.  Directing them to a particular website, they begin a WebQuest about... BUGS!  Each child becomes a type of bug (figuratively, of course).  Before long the kids are involved in small groups using the Internet, working on designing posters, and writing letters to plead with Terminex to spare their lives, citing all of the arguments for and against their existence.  Your role is that of facilitator.  You will be free to move from one group of students to another as they follow the guidelines and use the tools and information provided to them via the Internet.  This is an example of how a WebQuest can be used in the classroom.
