Addressing the many ways that literacy interacts with and supports learning, this book explores various aspects of middle and secondary school literacy instruction in subject area classrooms. The book presents a number of issues, instructional strategies, and classroom ideas for guiding students' literacy and language development in particular subject areas. Three features in the book are designed to guide readers' reflective thought and assist in transferring ideas from the text to the classroom: double entry journal activities at the beginning and end of each chapter; "how to do" features (step-by-step lists of things that need to be planned, prepared, or considered) occurring at irregular intervals in chapters focusing on instructional strategies; and "building tables" at the end of instructional strategy chapters that summarize critical information. Chapters in the book are: (1) Literacy in Middle and Secondary Schools; (2) Literacy Processes: Thinking, Reading, and Writing; (3) Comprehension Instruction in Content Areas; (4) Vocabulary Learning in Content Areas; (5) Reading across the Curriculum; (6) Writing across the Curriculum; (7) Assessment of Student Progress in Subject Area Reading and Writing; (8) Evaluating Instructional Materials; (9) Cooperative Learning, Literacy Instruction, and Content Learning; (10) Diversity in the Classroom: Meeting the Needs of All Students; (11) Developing Lifelong Readers and Writers; and (12) Making Connections in Middle and Secondary Schools. Three sample lesson plans and a list of professional organizations and journals are attached. (RS)
