Comprehension instruction is widely recognized as an essential component of developing students' pleasure and profit from reading. Yet despite significant recent gains in knowledge about how comprehension develops and how it can be taught effectively, classroom practice still lags behind research in this crucial area. This volume brings together the field's leading scholars to summarize current research and provide best-practice guidelines for teachers and teacher educators. Each coherently structured chapter presents key findings on a particular aspect of comprehension, discusses instructional practices supported by the research, and addresses what still needs to be known in order to provide the best possible comprehension instruction for every student. Topics covered include assessment, curriculum, methods, and comprehension difficulties, from the preschool level through high school.
