Research training is challenging, and the attrition rate of doctoral students has been increasing in Canada, the UK, the USA and Australia. In their book, Chen and Le examine the reasons for these students becoming demotivated, particularly in the context of TESOL. There has been much investigation into research training issues in multiple contexts and multiple disciplines. Yet, the research training process in TESOL for international students has not been explored sufficiently, and their voices have not been heard. This book gives voice to the research trainees, allowing their experiences to be reflected and the implications discussed in order to help create more effective supervision models. By employing the qualitative approach and adopting critical incident as a new technique for data collection, Chen and Le attempt to gain insights into the research training process to reveal different research stages of research trainees-those undertaking Ph D degrees-and to put forward a model of supervision to improve the innovation and quality of research. This book tackles the complex nature of research training. It is hoped that findings of this study can provide research supervisors and trainees with theoretical insights and practical references.
