The Bechdel Test is a simple way to gauge the active presence of female characters in Hollywood films and just how well rounded and complete those roles are. It was created by Allison Bechdel in her comic strip Dykes to Watch Out For in 1985. It is astonishing the number of popular movies that can't pass this simple test. It demonstrates how little women's complex and interesting lives are underrepresented or non existent…

rallain | May 20, 2010Grades are all over the place, but what are they? Well, I guess there are a few questions. What is a grade? What is the grade supposed to be? Why do we give grades?
I think the grade is supposed to be a measure of a students' understanding of the material. Probably everyone would agree with that description. But, it is still a bit tricky.

It is left up to the expert evaluations of faculty…
