To provide information to educators and curriculum developers on strengths, weaknesses, and needs of ethnic studies programs in Pennsylvania, the report offers an overview of the nature and extent of ethnic studies programs operated by Pennsylvania's postsecondary institutions, public school systems, and nonpublic schools. Information is based on data gathered in a survey of treatment by Pennsylvania's schools of racial, religious, and ethnic groups in courses, curricula, or programs. Data were analyzed from the perspective of democratic pluralism and were based upon the 294 Pennsylvania schools which reported having ethnic studies. The book is presented in five chapters. Chapter I introduces the study. Chapters II, III, and IV offer data for postsecondary schools, public schools (K-12) and nonpublic schools (K-12). The final chapter offers conclusions including that ethnic studies is a relatively new enterprise within the educational system and is increasing in importance in Pennsylvania schools. Recommendations made on the basis of this growth trend include that ethnic studies should be interdisciplinary, offered at all grade levels, a focus of teacher education programs, and an impetus to school/community communication. A survey questionnaire is presented in the appendix. (DB)
