Hello Joseph,
What a challenge--lazy students. I have been teaching business courses for over 19 years. I do not do all the talking even in lecture courses. I always get my students involved. The students that are lazy pick up on my teaching style very quickly, and they realize I must always be alert because I never know when I am going to be called on. I too call on the slacker alot more than other students so that he or she realizes, I must get my self together.
