Outlining an integrated language perspective on teaching and learning in the elementary school, this book provides both the theory on which the perspective is based and many examples of how it may be translated into practice. The book illustrates and explains eight thematic units (called "prototypes"), and includes webs, examples, activities, illustrations, tables, summaries, marginal comments and references that help the reader apply theory to classroom practice. Chapters in the book are: (1) The Theory of the Integrated Language Perspective; (2) Children and Teachers in an Integrated Language Classroom; (3) Planning Thematic Units; (4) Prototypes for Integrated Language Classrooms; (5) More Ideas to Integrate the Curriculum; (6) Learning more about Written Language; (7) More How-To: Ideas for Implementation in Integrated Language Classrooms; (8) Learning Kid-Watching Procedures and Techniques; (9) Evaluation and Accountability; and (10) Effecting Change through an Integrated Language Perspective.
