Qualitative research, especially studies in educational contexts, often brings up questions of ethics because the study design involves human subjects, some of whom are under age (e.g. data collected in primary education classrooms). It is not always easy for young researchers to anticipate where ethical issues might emerge while designing their research project. To help the young researcher, the authors include the research ethic statement drawn by the Grup de Recerca en Ensenyament i Interacció Plurilingües (GRIEP) research group as a guideline for setting up and carrying out qualitative research. They also provide an example of a signed consent form that can be adapted to the individual needs of each study. Websites with resources mentioned and consent forms for downloading (GRIEP model) are provided. [A Spanish version of this chapter is also included in the book. For the complete volume, "Qualitative Approaches to Research on Plurilingual Education," see ED573580.]
