Before we jump into any conclusion, I have to say that I'm not too happy to share the results in this post. But I'm glad that someone took the time and effort to create this interactive tool.
Created by Ben Schmidt, a history professor at Northeastern University, the 'Gendered Language in Teaching Evaluation' interactive lets you explore the words used to describe male and female teachers in about 14 million reviews from RateMyProfessor.com It allows you enter specific words to see how they correspond with the professor's gender and teaching discipline.
After playing around a bit myself, the data suggests that students tend to think more highly of male professors than females. Schmidt explains further about the interactive here and seems to be quite engaged through comments to discuss further.
