This edited volume assembles a series of articles and essays that address the impact of input enhancement (formerly consciousness raising), on current second language acquisition (SLA) theory, research, and practice. It represents a cogent and timely assembly of the implications of input enhancement on the second language teaching profession composed by experts in the field. While serving as a pedagogical tool for language educators at all levels of instruction, it is also a practical resource for students and researchers in education and applied linguistics interested in the role of salience, attention, and awareness in language learning. A Topics for Discussion section allows this volume to serve also as a textbook for undergraduate and graduate courses in language education and applied linguistics.
