This document consists on a 6-week curriculum unit designed to allow secondary students to actively explore issues associated with freedom of belief and expression. Throughout the curriculum students systematically examine the ways in which the legal and constitutional framework of our society directly embodies the norms of freedom of speech and minority rights. Students analyze the legal protections that have been afforded unpopular groups at the national level and parallel principles at the international level. Case studies, role playing, simulations, and mock interviews are used throughout the curriculum to examine the historical, psychological, and sociological dimensions of tolerance and intolerance. Information from psychological studies helps students understand why some individuals are particularly intolerant of beliefs that differ from their own. Descriptions of the Holocaust, the Cultural Revolution, and the internment of Japanese Americans during World War II direct students' attention toward the short- and long-term consequences of intolerance for the victim, the perpetrator, and society. The curriculum includes eight lessons and their corresponding handouts. Each lesson is divided into eight parts: (1) objectives, (2) estimated time, (3) materials and equipment needed, (4) vocabulary, (5) optional films and videos, (6) set induction, (7) learning sequence, and (8) closure. The lessons cover victims of intolerance, the origins of intolerance, basic human rights, censorship, political tolerance and U.S. courts, international rights and responsibilities, beliefs and believers, and developing a class declaration of rights and responsibilities.
