(Taken Spr. 2008) John Perryman teaches the biological aspects of human sexuality. You would think that this would be the dreary part of the course, but John makes it very interesting, mostly through the enthusiasm he himself has for the subject. He's been involved in the teaching of human sexuality at CCSF and other colleges for several decades, so this guy knows his stuff. John has a great sense of humor, and genuinely wants you to do well in the class. Every once in a long while, he would take a minute to remind us about the importance of attendance and doing the reading, but otherwise he is very approachable and will gladly answer questions. Pay attention to the practice test he hands out a few days before the quiz... those exact questions will most likely NOT be on the quiz itself, but they give you a good idea of what to study. Also, he will usually highlight the subjects he will quiz you on by saying something like "Hey folks, write this one down, cause it will DEFINITELY be on the quiz!!" The quizzes are scantron format, with about 50 bio questions. Bottom line: John is a great instructor, well-informed, and has a great sense of humor. If I had to, I would take another course with John without hesitation.
