This book discusses PCRP II, an integrative framework for language and literacy which teachers and administrators can use to examine, and when appropriate, to improve school and classroom practice in language use across the curriculum. Chapter 1 offers an introduction and summary. Chapter 2, "Perspectives on Theory and Practice," presents four perspectives for looking at the curriculum: learning as meaning-centered, social, language-based, and human. Chapter 3, "The Five Critical Experiences," (reading, writing, extending reading and writing, investigating language, and learning to learn) defines each experience, elaborates its specific research and theory bases, and suggests classroom activities applicable across the grades and across the curriculum, as well as activities for different grade levels and content areas. The fourth chapter, "Constructing Curriculum," addresses the integration of the five critical experiences in daily, weekly and long-range instruction and curriculum planning, and deals with ways to use the PCRP II framework as a heuristic for critical reflection on current practice and for designing units and planned courses of study. Chapter 5, "Designing Congruent Evaluation," maintains that integrative models of curriculum and learning are more likely to be successful if the evaluation program reflects these models, and proposes six principles for designing the evaluation procedures. The sixth chapter, "Implementing PRCP II through Networking," discusses the rationale for PCRP II and for the statewide plan for implementing the framework, and provides a set of specific but adaptable suggestions for how this book may be used to effect change at the level of districts, schools and individual classrooms. Twenty notes are included and an 11-page bibliography is attached. An appendix contains the report of the Pennsylvania Department of Education conference on PCRP II. (SR)
