You're absolutely right on this. I can't tell you how many "silver bullets" I've seen in my 24 years now. The amount of money spent on these various programs is probably mind blowing. I say probably because they never really tell us how much they've spent on things. At this point in my career, I follow their requirements as little as I can get away with and just teach as much as I can.
I remember the first time I saw “thinking maps” and found out our district had paid a consulting company something like $50,000 to give them a list of graphic organizers that we were going to be forced to shoehorn into every lesson.
