This precisely describes teaching theory as presented in schools of education today. We're living it; I'm not recommending a different method, but a different direction.
As for unintended consequences...that is a given. If I were generous (*and unskeptical) I would say we're currently drowning in unintended consequences.
It would be more accurate, I think, to say that we're not here by accident (unintentionally.) Any person who has followed education for the last 30 years would conclude we're here by design.
To cut through the cr@p, I'll propose that we both agree that the current system doesn't well serve students. Where we seem to disagree is whether effort is best used in trying to reform the current system or providing an alternative to it.
You note (correctly, I think) that human nature resists change. Combine that with the fact that the pressure groups currently control not just the system, but the terms of debate...and I say you have a better chance of sprouting wings and flying, than changing the direction of public schools.
Thoughts?
