If you've been following this blog for a while you can see that some things have changed. The original title of this blog (from 2004) is back, and I've added some new categories to make it easier for others to find old posts.
The image in the banner is of an ancient Babylonian clay tablet from around 1000 B.C. that illustrates a geometric proof. I thought this was a nice way to include triangles in a represention of knowledge, learning and education (KLE). Click on "About" to read a little more about my new (old) title, why I like triangles and the meaning of tryangulation.
I'm glad to have some teachers among my readers, and I'm very happy to share resources and ideas with them through this blog. I have changed the way some of my categories are arranged so that it should be easier for me now to post more resources more frequently, without them getting lost. So if I share something about science education here, I have a specific place to save it, and you'll have a specific place to look for it later (the "Categories" section on the right side of the screen).
