The Power of Explicit Instruction to Help Teachers Succeed at Higher Levels

If we provide students with no instruction, they will struggle at the level of the most basic questions. It's an interesting parallel that I think it's in our power as a system to help teachers to struggle at a higher level. Teachers who have been working 20, 30-plus years say to us again and again, why do I have to reinvent the wheel? Surely this has been done somewhere else?"
