Now in its second edition, Introduction to Instructed Second Language Acquisition continues to present a cohesive view of the different theoretical and pedagogical perspectives that comprise instructed second language acquisition (ISLA). Loewen provides comprehensive discussions of the theoretical, empirical, and pedagogical aspects of a range of key issues in ISLA, and has added to this edition a comprehensive exploration of the relationship between ISLA research and second language pedagogy. Also new is the addition of supporting features including new end-of-chapter activities, points for reflection, and discussion questions, as well as thoroughly revised content to reflect the most recent research in ISLA. This is an essential resource for students new to ISLA, or working in second language acquisition more generally.
