Why aren’t effective teaching tools widely adopted?
The fate of highly productive educational methods in public instruction is a national shame. No highly effective educational method or program has ever been widely adopted in North America. I didn’t understand and accept this until 1983, when I read the results of Project Follow Through and how they had been ignored and covered up (Car-nine, 1983; Engelmann & Carnine, 1982). Here, the clear-cut results of the most extensive and most expensive educational research ever conducted were being ignored. You couldn’t even get the reports out of Washington. These were the results of investing public funds, and they had run out of reports! They couldn’t find them! “Call back next Monday!”
