can school make you stupider?

At the conclusion of 6 hours of lecture, it grieves me that the only thought swimming through the ocean of my brain is, "Can poor instruction lead to learning disabilities?"
All these little people that we label as 'special' and 'gifted' and whatever other politically correct rhetoric we can think of, are probably just bored out of their little minds listening to egocentric teachers drone on and on and on about meaningless fluff.
What a waste of valuable time...time we could have used to bake cookies. Think of how fat and happy we'd be if we baked cookies instead of attending class (even just for a week!). We could work towards feeding the hungry and surprising our grandmas. What could go wrong in a world like that? (Don't answer that question.)
But alas...
