Recent research and program development in the areas of metacognition and related teaching and learning strategies is the subject of this issue of the newsletter. The lead article reviews reasons for the current interest in cognition and metacognition, clarifies the concepts of cognitive and metacognitive strategy instruction, and describes key elements of effective strategy instruction as suggested by recent research. Applications of strategy instruction in such content areas as reading comprehension, written language, social skills, and mathematics are described, and possibilities for future program development are discussed. Additional sections of the newsletter highlight two instructional materials packages, summarize current articles and research on metacognition, and describe a videocassette program which illustrates critical teaching behaviors in each of eight identified steps for learning strategy instruction.
