This course provides an overview of sociocultural approaches to second language (L2) learning and teaching by introducing foundational and emergent theories and concepts that have shaped and guided research and teaching practice in this area. It will build on your knowledge of second language acquisition and encourage you to consider how sociocultural approaches can inform work in this area. Topics covered will include, but are not limited to, the quality of interaction desired for L2 learning and development, the role of the first language (L1) in L2 learning, task vs. activity, and the roles of teachers and peers as socializing agents. The course will also examine the implications that sociocultural theories have for the teaching of English as a second/foreign language (TESL/TEFL). You will be encouraged to use the concepts and insights provided by this course to reflect on and analyze activities that transpire in your own classrooms. Thus, the major goal of this seminar is to help you deepen your understanding of L2 learning and teaching by means of sociocultural theories. More specifically, the course aims to help you develop a solid understanding of sociocultural concepts and principles and make practical applications of this knowledge in your own situations, and thereby to facilitate your learning and development as EFL/ESL teachers.
