This volume examines the uses of technologies in language test design and validation. Following Cyril Weir's socio-cognitive framework, it reports a series of research studies to shed light on the efficacy and challenges of using technologies in key areas of language test validation. Technology has become an important resource for refining methods of assessment and research. This volume focuses on the uses of cutting-edge technologies in language test design and validation. Using Professor Cyril J Weir's socio-cognitive framework as a basis, diverse contributors explore the potential and limitations of applying innovations in data collection to language assessment research, and address the validity issues arising from the use of artificial intelligence such as automated scoring and feedback. In addition, the volume reflects on how fit-for-purpose the socio-cognitive framework is for language assessment research and practice in light of technological advances.
