I too, am an undercover direct instruction teacher. I just smile and nod and act like I agree with all the Discover Learning evangelists who come to our school and do professional development. Then I go into my room, shut my door and do what I know is right.
No one can argue with my scores though. I was asked by our principal to take three sections of 10th graders who are on the "bubble" this year because our school did not meet AYP last year based on 10th grade math scores. He's not really sure what I am doing with my classes, but he's smart enough to know it works!
