This issue of New Directions for Teaching and Learning elaborates three theoretical perspectives through which teaching can be viewed and explores their implications for the practice of teaching. These theoretical perspectives are the cognitive, which deals primarily with strategies by which information is processes; the motivational, which deals primarily with how learning is initiated and sustained; and the social, which examines the interpersonal context of teaching and learning. This volume also discusses personal, implicit theories and how instructors can weave multiple perspectives together to solve instructional problems. This is the 45th issue of the quarterly journal New Directions for Teaching and Learning. For more information on the series, please see the Journals and Periodicals page. Read Less
