I've found that adult students really crave that personal attention from an instructor who really wants to help them succeed. Succeeding to an adult student is typically not an abstract concept like it may be to a traditional college student, adult learners want to know how the material will directly impact what they'll be doing in the work place. An instructor who ties real world scenarios to the concepts being taught in class is much more valuable to the adult learner. The bottom line is knowing the needs of your customer and then delivering on those needs, they're paying a lot of money to take the classes so making the learning practical is typically what they want.
