I’m so pleased to be back in Denmark for this year’s European Council of Independent Schools conference and look forward to meeting and sharing with lots of colleagues. This year’s theme is one particularly close to my heart. Today working with some local school principals, I presented my idea about “learning ecosystems,” and one of the principals astutely observed that no ecosystem can survive without the input of energy. When we look at the natural world around us, that energy comes from the sun — plants transform that solar energy into sugars and fibers, and herbivores, carnivores, and scavengers continue that transformation. “What,” he said, “is the energy that drives and transforms learning ecosystems?” His answer — and mine: curiosity. Everything else we do is driven by its energizing force. If you’re around Copenhagen tomorrow, I’d love to see you. You can find out more about the conference here.
