[Rafaeli]'s book is an example of how wikis could change classrooms from the ground up, a topic at the Wikimania conference this weekend at Harvard Law School, where Rafaeli's work will be presented to wiki enthusiasts and academics from around the world.
A wiki the word means "fast" in Hawaiian is a technology developed in the mid-1990s that lets readers edit and rewrite Web pages. There are private wikis, open to certain readers and editors, and public wikis. Then there are wikis in between, viewable by everyone but rewriteable only by a select few.
[Vicki Davis] grades her students' wikis like essays, focusing on accuracy, critical thinking, and participation. She said it isn't harder than grading a classroom's worth of papers because she gets e- mail updates on the wiki and tallies student edits on a chart. Rafaeli grades solely on whether students make the required number of updates.
