The Handbook of Technology and Second Language Teaching and Learning presents a comprehensive exploration of the impact of technology on the field of second language learning. The rapidly evolving language-technology interface has propelled dramatic changes in, and increased opportunities for, second language teaching and learning.  Its influence has been felt no less keenly in the approaches and methods of assessing learners' language and researching language teaching and learning. Contributions from a team of international scholars make up the Handbook consisting of four parts: language teaching and learning through technology; the technology-pedagogy interface; technology for L2 assessment; and research and development of technology for language learning. It considers how technology assists in all areas of language development, the emergence of pedagogy at the intersection of language and technology, technology in language assessment, and major research issues in research and development of technologies for language learning. It covers all aspects of language including grammar, vocabulary, reading, writing, listening, speaking, pragmatics, and intercultural learning, as well as new pedagogical and assessment approaches, and new ways of conceiving and conducting research and development.  The Handbook of Technology and Second Language Teaching and Learning demonstrates the extensive, multifaceted implications of technology for language teachers, learners, materials-developers, and researchers.
