I really liked the comment that adult learners want to "start on time, finish on time, and not have their time wasted." I have experienced this with adult learners who frequently ask, "How am I going to use this?" They want to know why they are learning the skill I'm teaching, and they do not want me to "waste" time on things like "teambuilding" or infrequently used grammar rules. Sometimes that's difficult to work with, but frequently I appreciate their drive.
