BECOMING A WEB STAR with online lectures:

Walter H. G. Lewin, 71, a physics professor, has long had a cult following at M.I.T. And he has now emerged as an international Internet guru, thanks to the global classroom the institute created to spread knowledge through cyberspace.

Professor Lewin’s videotaped physics lectures, free online on the OpenCourseWare of the Massachusetts Institute of Technology, have won him devotees across the country and beyond who stuff his e-mail in-box with praise.

Traditionally, teaching has played second-fiddle to scholarship at many institutions because it can’t get external plaudits. I wonder if online course will change that.
