If you liked Inspiration/Kidspiration....

...you might like Webspiration.

It's from the people who make Inspiration and Kidspiration.

"Use Webspiration to map out ideas, organize with outlines, and collaborate online with teams or colleagues. Create concept maps, mind maps, idea webs and other powerful visual thinking models in Webspiration's Diagram View.  Build organized outlines, plans and reports with Webspiration's Outline View. Webspiration unleashes your creativity, strengthens organizational skills, and transforms your ideas and information into knowledge."

And check out this list of 50 ways to use Inspiration/Kidspiration (pdf) from University of Wisconsin at Stout.

There are dozens of online concept-mapping tools.  In addition to Mindmeister, two of my favorites are bubbl.us and Mindomo. You can read more about bubbl.us from a classroom teacher who uses it and you can see some Mindomo maps on my wiki page about choosing the right tool.

I also like Text2MindMap.   You just type in your text and it makes the web from your outline.  Magic.

Mindmaps or concept maps are examples of graphic organizers.  If you haven't explored some of the templates in your subject area/grade level available from Inspiration, do it!  You'll get lots of ideas for lessons that help students visualize their learning.  And here's a presentation that appeared in my RSS reader this morning:

I'm beginning to see a number of graphic organizing tools available for the ipad, ipod touch, iphone and android phones, too.
