Kevin W. H. Tai, PhD in Applied Linguistics at UCL (London) and current editor of journals such as the International Journal of Bilingual Education and Bilingualism (Routledge), presents his book Multimodal Conversational Analysis and Interpretative Phenomenological Analysis: A methodological framework for researching translanguaging in multilingual classrooms in early 2023. In it, Tai discusses both the combination of two types of analysis (multimodal conversational and interpretative phenomenological), as well as more theoretical aspects of his study, such as the differentiation between translingualism and code-switching or the different definitions that translingualism has received in the last two decades. In order to defend the joint use of these two analyses, Tai presents part of his doctoral research. In addition, he responds to the criticisms of invalidity that the interpretative phenomenological method has received. In this review, I will present the structure of the book, the division of chapters, Tai's bibliographical summary, and Tai's exposition of theories and criticisms.
