Hi Carl: It is obvious you've used these helpful activities before. Students do interact in a social way that's different from the classroom, and these can't be duplicated in the classroom or skills lab either. The cool thing is often a good experience will inspire and provide an inner motivation that begins to burn like a desire to really excell in some students to the degree they begin to perform better in class. The thought of of a better (potential) future is a hard motivation to overcome. I'll take that any day. Regards, Barry
