I think about this issue every day, about the pushing down of curriculum. I think about how my pre-K classroom for at-risk four-year-olds is what many people envision a Kindergarten classroom to be. I bend over backwards to keep our learning fun and hands-on and full of light-hearted exploration, but I'm still asking them to come meet me in what I have designed, and it normally involves numbers, letters, and concepts that they are expected to know before they get to Kindergarten in my school district. I jealously guard their precious self-directed time, but it's still not enough in a day of so much curriculum to get through. I think about how many middle-class peers of my low-income students, in their private preschools around town, are getting lots of richly resourced, free exploration time.
There are times when I'm proud of what my students are learning and all the fun they're having while they're learning, and then there are times (when I read this article for instance) and I think, yowza, my program is part of the problem.
I have a lot to think about.
