For more than seven years, opinionated college students from 6,000 schools around the world have spoken out about teachers they love and loathe at Ratemyprofessors.com. Recently some Boston University professors have gotten into the game, calling out comments they thought were unduly harsh — and leaving some students questioning their professors’ professionalism.

“The way I understand it, [the interview] was just for fun,” College of Arts and Sciences CORE lecturer Sassan Tabatabai said. “If [the site] was something I took seriously maybe things would have been different.”

Earlier this month, on the heels of mtvU’s recent acquisition of the popular Web site, Tabatabai was given the opportunity to react to student-generated comments in an mtvU.com segment called “Professors Strike Back,” in which he choose some less-than-delicate words.

In the interview, Tabatabai called the negative-commenters “shit heads.” One anonymous student poster wrote that Tabatabai was “worthless as a professor” and, to this, Tabatabai told mtvU this student was probably “worthless as a student.”
