Many colleges and universities allow older people to audit courses tuition-free. But–perhaps because the arrangement does not generate tuition–most institutions do not actively promote this option or encourage people to take advantage of it; the number of older people who actually enroll in such courses tends to be fairly low. Suppose that your college began taking aggressive and effective measures to encourage elderly people to enroll in courses, with the eventual result that around half of the students in most classes were 65 or older. Write a paper discussing two issues. First, how should instructors modify their teaching and their evaluation and testing procedures in response to this change in the student population, given the material in the text describing older adults’ cognitive performance and abilities? Second, how would classes be enriched by an increase in the proportion of older students, and how would classes suffer through such an increase?
