Gender in the Classroom

This semester, I have 4 Communication classes, and one Journalism class. All of my professors happened to be women. In my whole 'college career', I have only had a handful of male professors. Until now, I hadn't realized that most of my professors have been women. In class on Thursday we did a debate on single-sex education. While doing research for the debate, I came across the fact that most elementary to high school teachers are female. It never crossed my mind that same may go for colleges as well. As far as the gender ratio for students goes, I feel like most of my classes until now have been about 50/50. Now that I am into all of my Communication classes, I notice there are mostly girls. That's not to say there aren't any guys who are Communication majors, I just notice more girls in my classes. It may have to do with the fact that, as our book states, for feminine people, talk is the essence of relationships.
Another point that came up during the debate was the fact that teachers tend to focus more on boys in Science and Math and focus more on the girls in classes like Reading. Looking back at my elementary and high school years, I may have to agree with that. However, I have not noticed that to be true in my college classes. I feel all of my professors have treated and talked to each student the same way, they are not gender biased. This has been true for my English and Communication classes, as well as my Math and Science classes.
I am curious to read other students blogs and see if they have noticed the same things I have or if their observations are completely different.
