Featuring a mock trial tested in the District of Columbia, the objective of this manual is to help students learn more about the constitutional guarantee of trial by jury. Prepared as five separate lessons, the manual examines one alternative to the jury system--trial by ordeal; traces the development of the guarantee of trial by jury; explores the jury selection process; describes and explains the characteristics of a trial and the role of juries; and provides information and materials for a mock trial, Vickers v. Hearst. Each lesson contains objectives, background information for teachers, activities and handouts for students, and an annotated bibliography. Appendices direct those interested in law-related education programs to additional sources of information. (TSV)
