Instructed Second Language Acquisition

Abstract

Instructed second language acquisition (ISLA) is a subfield of second language acquisition (SLA) that investigates any type of second language (L2) learning or acquisition that occurs as a result of the manipulation of the L2 learning context or processes. Learners' self‐study of the target language is also considered part of ISLA; however, ISLA research has generally focused more on traditional, face‐to‐face classrooms, as well as online instruction. The defining feature of L2 instruction is that there is an attempt, either by teachers or instructional materials, to guide, facilitate, and manipulate the process of L2 acquisition.
