“This anthology is a timely source for innovative practices of language-teacher education, dovetailing them with work based upon Complex Dynamic System Theory (CDST) and Positive Psychology (PosPsy). ... a more holistic view of the professional development and the well-being of language teachers is adopted throughout. ... As it caters to different scholarly and practical needs, the volume is recommended to a readership that will include FL/SL researchers, language-teacher educators, and both pre-service and in-service teachers.” (Chengchen Li, Journal of Multilingual and Multicultural Development, April, 2018)
