A general education psychology class has a section on human sexuality and students are required to demonstrate knowledge of human anatomy and sexual response. The instructor explains that a sexually explicit educational DVD will be shown to the class. Selma approaches the instructor and tells him that her personal values prohibit her from participating and so she will not attend the designated class session. Since students are awarded “participation points” for class attendance, she expresses concern that she will be penalized. What should the instructor do?
