I teach some of the begining courses, and as a result some of the material in my class is fairly basic. Some of the students have passed a basic test to work in the industry, yet i have to cover this material as a starting point. They get VERY bored and disruptive. I've tried the reasoning approach, by letting them know if they have some industry experience that they should take this opportunity to affirm their knowledge. Some do this, others become disruptive and rude.
Then what? They know the info, I'm not teaching them anything...I'd be bored too.
