AlexM,
This is not an answer to your question, but it may help you some.
Try PRing the teacher. Yes, you read correctly, PhotoRead the teacher. He/She is showing all kinds of talent and knowledge in front of the class. Be sure to state your purpose exactly, "I want this certain knowledge and understanding of things from my teacher". If you don't state your purpose exactly enough, you will get also the behaviour of your teacher.... you may not want it...
The information you get will most certainly be activated automatically.
I'm not in school anymore, so I've not done it with any school teacher, but I've done this with my Qi Gong teacher. Works wonders! -purjo
