I am in total agreement with Carolyn. Students need to be reminded every now and then "What is in it for them". Remind them now and remind them again after a few days. It is like giving a tune up for our car. After a tune up the car will run smoothly for a while. It starts slowing down after a few months. Well, it is time for another tune up. We need to stay on it. Majority of students will get the message and they will stay focused.
