Students-Teach-Students is a program that trains teams of high school students to present a smoking education program and role-model to fifth graders, helping them to overcome peer pressure to smoke cigarettes and marijuana. Surveys show that a significant percentage of students first begin to experiment with smoking cigarettes and marijuana during the fifth grade. The most frequently cited reason to experiment with smoking is peer pressure. The Students-Teach-Students program trains high school students who can communicate easily with the younger students. The high school students through role-modeling give the younger students the answers they need when faced with peer pressure. Immediately prior to the high school students' presentation, fifth grade teachers are given a complete 5-day curriculum that outlines smoking prevention activities for the children each day. The high school students reinforce what has just been taught by the fifth grade teachers. In 1990 the American Lung Association affiliate in the Gulf Coast region of Florida, trained 764 high school students reaching 7,314 elementary school children. It was evident by pre- and post-test statistical comparisons that the program was a huge success. This program is geared toward secondary and elementary school counselors and teachers. (Author)
