This is a really cool free site that’d be great to use in the classroom.
You pick a topic from wikipedia and it creates an interactive mind map of the content. Click on the pluses and topics expand. You can even change the “center” topic of the map on the fly. Lots of cool stuff you could do with this and it’d be a great way to get to those visual learners that don’t respond well to outlines or even static mind maps.
Too bad you can’t point it at any mediawiki site. That’d really open up some interesting options in the classroom.
You CAN point it to other mediawiki sites. Just hack the URL.
Here is an example:
http://www.wikimindmap.org/viewmap.php?wiki=en.wikibooks.org&topic=astronomy
