This looks like another great resource for educators. We crave tools and this site offers hundreds of them. http://improvencyclopedia.org/categories/index.html
"This is a collection of games/exercises/handles/techniques for improvisation theatre. It's basically organized in Categories , and each improv Game is classified in a number of these categories. We also provide a number of Glossary and References to people, sites and books where you can find similar information.
"This site does not aspire to:
- list as many improv troupes or people as possible. Check out New Improv Page instead
- list as many improv events as possible. See New Improv Page and YesAnd.com for events.
- build an Improv community or start discussions about improv. Go to YesAnd.com or Improvresourcecenter.com for discussion boards. More recently Facebook has seen the creation of several improv communities ( see Facebook ) for some links."
