Imagine learning to ride a bicycle, and maybe I give you a lecture ahead of time, and I give you that bicycle for two weeks. And then I come back after two weeks, and I say, "Well let's see. You're having trouble taking left turns. You can't quite stop. You're an 80 percent bicyclist." So I put a big C stamp on your forehead and then I say, "Here's a unicycle." But as ridiculous as that sounds, that's exactly what's happening in our classrooms right now.
How else would people learn to ride a bicycle if you didn't give them a lecture about it ahead of time?
