The purpose of this publication is to provide educators with useful information on and examples of how teachers and students can better communicate and learn in today's culturally diverse classrooms. Educators are offered background information and resources for increasing sensitivity and responsiveness to the needs of students of different cultures and enriching their students' curriculum by infusing it with a multicultural perspective. The publication is divided into five sections. Section 1 provides an overview of cultural diversity and the impact it has on U.S. schools. It also addresses the critical role teachers play in facilitating effective learning within culturally diverse classrooms. Suggestions are offered for becoming more sensitive to culturally diverse student and community populations. Section 2 features "Dynamite Ideas"--programs and projects that teachers have used successfully in addressing the needs of culturally diverse school populations. Section 3 presents a compilation of structured strategies for developing cross-cultural awareness and sensitivity and a wealth of thematic activities and related resources that can be used in the classroom. Section 4 provides annotated listing of state-level initiatives, resource centers and organizations, publications, curriculum guides, and training programs. The five appendices offer additional resources and information: "Helpful Hints for Working with New Limited English Proficiency (LEP) Students"; "74 Instant Ideas for Classroom Teachers with ESL Students"; "Sample 'Culturgram'"; "Chronological Reference of Key Historical Events Related to U.S. Ethnic Groups"; and "Myths and Facts about the 'Discovery' of America and Native Americans."
