Whle I agree that students can disengage due to a predetermination that the course will be of no value - a waste of their time, there are a LOT of reasons why working adult students disengage. There are priorities that do not apply to the full time graduate student or even the college student. I'm not talking about football games or fraternity/sorority events - my students are typically a generation behind me - not 3. Jobs, kids, grandkids, homes - life. It's not all about boredom.
