In an increasingly global and mobile society, language learning has become critical. The authors of this book present new research in the study of language learning, including CALL technology for literacy and second language learning; the effect of biliteracy instruction on English reading achievement in bilingual South African children; vocabulary knowledge and reading ability in second language learning; multilingual learning; language learning through SMS and podcasts and the linguistic specialisations of perceptual narrowing of speech and functional asymmetries.
