This brochure presents an introduction to the Choices for the 21st Century Education Project. The project seeks to promote discussion of current issues in the high school classroom. Of particular focus are topics pertaining to international relations. Central to the Choices approach are analyzing issues, articulating viewpoints, respecting the views of others, and making informed judgments. The project offers a series of documents that draw on current research, educator recommendations, and classroom testing to develop curricular units appropriate for high school social studies instruction. Units present students the opportunity to step back from contemporary headlines to consider current events within the U.S. political and philosophical heritage. Materials are self-contained and ready for the teacher to use. At the core of each unit is a range of contrasting policy alternatives to consider. Each unit provides background readings, lesson plans, and student activities. In addition, there are materials for teachers, including primary documents, a suggested reading list, and ideas on examining related topics. Most units contain a 1-week lesson plan. (SG)
