Over 400 promising practices used in Pennsylvania elementary and secondary schools are catalogued. Material is divided into 23 chapters. The first 12 chapters arrange program abstracts according to objectives of the Pennsylvania Goals of Quality Education: communications, mathematics, self-esteem, analytical thinking, understanding others, citizenship, arts and humanities, science and technology, work, family living, health, and environment. Chapters 13 through 23 list programs not specifically related to state mandated goals: administration and management, programs for advanced students, programs for special needs students, curriculum, early childhood education, guidance and support services, parent and community involvement, and professional evaluation and staff development. Within each chapter, the program abstracts are arranged in one of two ways. Where grade level is a relevant criterion, program abstracts are grouped alphabetically by program title within the categories of elementary, middle school/junior high school, senior high school, and K-12. Otherwise, programs are arranged alphabetically by title. Included in each entry are names and addresses of districts, the year program began, and sources of additional information. An index concludes the catalog. (LP)
