I'm behind on my link love, but I'm trying to catch up. Here are a few of my favorites:
Childhood 101 has several really great posts lately :: 10 Tips for Creating Great Play Spaces, Playing Creatively, and Developing Brains: Laying the Pathways to Learning are all worth a read
Ecology of Education :: Creating the Optimal Learning Environment, What Makes a Master Teacher?
Education Revolution :: Democratic Education With Young Children (a talk given by Elizabeth Baker of the Patchwork School at the Voyagers' Conference, very good!)
