Science literacy maps

One of the better teaching development methods to come out of the standards movement has been literacy maps, graphs showing how strands of concepts can be taught over K-12 to build a framework of understanding we call literacy in a concept.

For an example see the energy concept strand kept online at the National Science Digital Library: http://strandmaps.nsdl.org/?id=SMS-MAP-2246

In 2005 I attended a workshop for developing such maps led by Curriculum Topic Study. I and several other science teachers practiced building such maps.
