What value would it be to know that you were going to be training a class of persons between the ages of 20 and 35? Would it influence the approach you would take? How? Suggestions you would make to instructor or trainer?
I would try to tie the coursework into the business world. Also, seeing as they are choosing to take the class I would spend less time trying to motivate the students to learn. I would suggest to the instructor that the students should be capable of substantial independent work outside the classroom.
