This curriculum unit contains 10 modules, to be used in 10 driver education class sessions, on driving under the influence of alcohol and/or other drugs (DUI). The unit aims to combat the Oregon DUI problem, especially among 15- to 24-year-olds, with values clarification, awareness of risk factors and personal boundaries, refusal skills, social responsibility, decision making, and group bonding. It also explores chemical effects on brain and body function. Each module is a complete lesson plan for a 50-minute period, with an optional 2-hour final session to be used just before graduation. Time frames are suggested for each activity within each module, and activity sheets for duplication follow each module. Supplementary materials (resource lists, suggested references) and unit tests are provided. Three 2-hour reinforcement sessions and a parent module also are included. (KC)
