This volume gives readers insights on the use of technology in professional development programmes and content knowledge that can enrich teacher education. Every chapter of the book builds, through research, an analysis and discussion of CALL matters and professional development. The purpose of the EuroCALL Teacher Education SIG's edited volume, supported by the Language Centre of the Cyprus University of Technology, is to respond to the needs of language educators, teacher trainers and training course designers through relevant research studies that provide technological, pedagogical, and content knowledge. The book concentrates on professional development in CALL, the use of technology in primary, secondary, and tertiary education, e-learning facilitators, the integration of personal learning environments, the use of MALL, the applications of virtual reality, materials design, the use of ICT in task-based language teaching, and the integration of social media networks in language education.
