All adult students have one challenge or another at some point during the time you have them in your course. Financial, personal, medical and family problems can rear its ugly head at any point. I try and see how each student is acting in class on a daily bases. Any change in their attitude or demeanor that lasted more than a couple days, I would meet with them to talk about the problem. Letting the student know that they are not alone sometimes helps. I try not to become their therapist but tell them they can vent to me. This approach along with telling them to try and leave their problems at the door .
