Physic Teacher

I watched the class for a popular physic teacher. Economist try to be physicist with the various laws (such as Law of Demand etc.) that sound similar to various Laws in physic. So I decided to see how she makes physic interesting and maybe I can steal some of her ideas. She uses a method called "Peer Instruction". She starts out with putting up her learning objective for the day. She starts what seems like a standard lecture except that after every learning objective she puts up a difficult multiple choice question on the screen. She has the class divided into four sections. Each section correspond to a choice on the screen. The students will have to decide on the correct answer and move to the corresponding section. The students are given 5-10 minutes to discuss , come up with the correct answer and move to the correct section of the room for the question.
This was very fun but I noticed a problem with this technique is that prepared students build a reputation and quickly get a following. Unprepared students just wait and follow the well prepared students.
