This curriculum guide for high school students sensitively and expertly addresses the escalating social problem of suicide. This guide is part of a series designed to provide educators with the curricular tools necessary to challenge students to take personal responsibility for their health. With seven structured lessons, this teaching unit focuses on suicide as a process that involves a series of steps and stages at which intervention can take place. This guide also stresses the importance of involving parents, students, school personnel, and the community in a comprehensive suicide prevention plan. Specific steps for implementing a plan are provided in the appendices. This guide for suicide prevention provides the facts, structure, and guidance that teachers and students need for informed intervention; positively influences students' mental health by giving them information and skills to deal with depression and increase awareness to suicide; examines the causes of depression and common facts and myths about suicide; and encourages students to identify personal and community resources for helping. Each lesson includes information on the lesson objective; class time required; a brief overview of the topic; instructional strategies; teacher materials and preparation; procedures; key points; and evaluation materials. A separately bound student workbook contains identical exercises and activities for students as those found in the teacher's guide. (ABL)
