A Nobel Prize winner's experiment suggests that how you teach is more important than who does the teaching — especially when it involves a large college physics class.

The study was led by 2001 Nobel laureate and physicist Carl Wieman who is now a science adviser to President Barack Obama. He found that students learned a lot more from grad student-instructors using interactive tools than they did from a highly-rated veteran professor giving a traditional lecture.

The study was done at the University of British Columbia and appears online Thursday in the journal Science.
