Anyone who serves teenagers today knows that more and more young people are eager to make a difference in the world. When students participate in short-term missions, service, and justice causes, parents and youth leaders hope these experiences will lead to real transformation. But research shows that our efforts don't always stick. If we truly want short-term work to translate into long-term change, leaders and students must spend more time before, during, and after service projects preparing for and processing their experiences. The sessions in this leader's guide will help you create experiences that stick--both for the students you take and the communities you serve. This guidebook offers a host of practical and field-tested exercises for each phase of your experience, whether it's a half-day local service project or a two-week trip overseas. Participants will engage in hands-on experiences to gain new insights about themselves, their relationship with God, their teammates, and the world we're called to love and serve. Each of these steps is a catalyst in helping students apply what they have learned in the field to their own lives back at home. Also included are ideas to help get parents and the whole church engaged in service together. A companion student journal is also available to boost the potential for personal application throughout the journey.
