Chapter 5 discusses features of research involving children in applied linguistics. Based on a strategically selected ‘slice’ of the literature, namely, a survey of child L2 studies in five key applied linguistics journals between 2011 and 2021, a close analysis of children’s status and roles in research is undertaken. Observations are made about the type of studies (methodological solutions, tools, and approaches) dominating the field and about what is missing. Examples of studies in child second language education where children take up different types of passive roles are discussed and analysed. A handful of examples identified in the sample where the status and the roles of the children have been shifted away from entirely passive roles are also discussed. These examples are closely examined to identify the extent of active involvement that does not move beyond a ‘weak’ form of research ‘with’ children. The continuum of possibilities, research on-about-with-by children (Kellett, 2010a) is revisited here for further reflection.
