The majority of students at all universities are female, hmmm. There might be other issues than bias or sexism. The biggest problem with contract Instructors and Professors from family experience is the inibility of some Instructors to speak and write english. Perhaps this is a reason for some bad reviews. Some Instructors are so poor at communicating verbally and in writing that it is a waste of time going to lectures. In fact, I'm told that it is less confusing to study independentley than to attend a lecture and become completely confused by an incoherent lecturer. I have seen some of these lectures online and between poor language skills, echos and other noises it is tiring to listen to and tedious to watch. I am told that being present at the lecture is no better. Maybe department heads should attend lectures or set up cameras where they can monitor them on their computer. Perhaps capture some of the teaching gold for Performance Reviews, and don't dump the responsibility on kids.
