Metalinguistic Awareness and Second Language Acquisition is the first book to present an in-depth overview of metalinguistic awareness as it relates to SLA. In this volume, Roehr-Brackin discusses metalinguistic awareness in the context of both child and adult language learning, and outlines the various methods that can be used to measure metalinguistic awareness. The author presents different approaches to metalinguistic awareness, including a cognitive-developmental perspective that explains how the concept relates to literacy, and an applied linguistics perspective that understands metalinguistic awareness as explicit or conscious knowledge about language. Roehr-Brackin explores the role of metalinguistic awareness in language education aimed at young learners, as well as in instructed adult SLA. This book is an excellent resource for those researching or taking courses in second language acquisition, bi- and multilingualism, and language teaching.
