ABSTRACT
This chapter describes the relationship between second language acquisition (SLA) research and the field of applied linguistics across “applied” and “applicable” orientations. It focuses on applied studies designed to address practical questions and concerns and on applicable studies designed to address theoretical questions, but also relevant to applied questions and concerns. Three questions are addressed: Is there an optimal age to begin formal classroom second language (L2) study? Are there effective ways to integrate a yet to be acquired L2 with subject matter content? What are the contributions of a first language (L1) to classroom teaching and learning?
