This book makes a fresh contribution to the field of research ethics by considering research issues through relatable autobiographical narratives. The book’s core offers narratives by novice second language education researchers who are completing PhD degrees using data from international research participants. These narratives expose challenges regarding the ethical identity of researchers working across diverse value and belief systems. The narrative chapters are followed by four chapters of commentaries from a line-up of international scholars with various academic, linguistic, and cultural backgrounds. The case study approach reports the experiences and reflections of research students before, during, and after the data collection phase of their projects, and offers insights into the recruitment of participants; acquiring and maintaining access; interpretations of the notion of informed consent; incentivising participants; the implications of ensuring anonymity and confidentiality; the right to withdraw participation and data; the positioning of the researcher as insider or outsider; potential conflicts of interest; the potential harm to participants and researcher; and the dissemination of findings. This practical and relatable book is aimed at research students and their supervisors in fields such as applied linguistics and education, as well as those following methods courses, to help illustrate the ethical challenges faced by researchers in the process of collecting qualitative data.
