The purpose of this module is to provide a sequence of readings and learning experiences that will introduce a broad range of theories that inform and underpin second language teaching and learning in the classroom. A critical review and practical applications of these theories will assist you in designing classroom learning experiences, developing a classroom learning community, and assessing progress towards the expected student learning outcomes. We will cover the primary theories and perspectives related to second language learning including behavioral, developmental, cognitive, social cognitive, sociocultural, and constructivist learning theories. In addition, we will examine how different theories conceptualize language learning and address students’ motivation and self-regulation as well as classroom management.
