If you do that, if you change the state of the brain for advanced learning, the human brain -- indeed probably most animal brains -- adapt in one very predictable manner. They become excellent learners in the new state, and stop learning entirely in the old state.
Which means you'll learn great in the classroom, and you'll learn absolutely nothing from normal experiences -- when you're off the juice.
Which is crazy dangerous, since it'll basically erase the expertise part of experience.
Again, and as usual, this is a great idea for immediate safety-related stuff. Teach CPR this way, train soldiers this way. But normal learning is a different animal. Slower learning isn't usually a lack of learning skill -- it's often a stubborness to stick with existing knowledge, and that is most often a very good thing. You don't want to lose that in general.
Do you have any evidence to support said claim that "normal" experiences somehow differ in learning than "classroom" learning? While "street smarts" and "book smarts" are accepted differences, they refer to knowledge, rather than learning.
