Life is a jumble.
Long before brain researchers foun out that we each store information differently Dewey, Holt and other pedagogs recognize the power of concentrating on one student at a time. The current school system makes that impossible. But by creating learning communities, collaborative homeschooling, and other tools, a future learning sytem could be devised that recognizes what science tells us. I don't think we have to search far to find the edge of chaos. Most school rooms have already reached it.
