text: Instead of forcing students to do community service, I think you would be more successful if you gave the students some sort of reward. If they had an incentive or reason to be doing what they're are doing, they will work harder and more people will sign up. Although, there are the students who want to help out the community and they probably will regardless of if there is a reward or not. You might want to acknowledge them for their kindness and generosity. Maybe people will see that and think they could be and do something great too.
