I would have to say the Bill Gates comment is the best for me, as I see the teacher as being the most important. I say this because you still here the teacher plays a secondary role, but I see this as starting the proess of faciltator, and yes, in this case the teacher is trying not to be the main priority, and et learning be.
I see it like this, you need to have a mature, intelligent, and creative enough teacher to be able to loose the reins of their class and be willing to learn off the students as well. Many teachers take this as a put-down, but truly the teacher with his/her attitude has the ability to stand back and let students take more control, serve as observer, as well as take those reins back again whenit is necessary.
The teacher certainly is the most important aspect as he/she can impact the memories you will, do, or won't have about your educational experience!
