I would perfer to think if a student signed up for a class they would be interested enough to complete the class on their own. Would I encourage some one that was having a difficult time to seek out some one else in the class for help or tutoring ? absolutely I generally take people at their word. Maybe this is a flaw in my way of thinking. I would rather see what I can do to help a student than try and catch some one cheating. I think what I want to say is I must have not taught some thing very well or I must not have made myself as available as I should have. If a student has to cheat to pass I going to take some of that responcibilty.
