At the centre of this book is the exploration of how logic-in-use both leads to a particular understanding of the phenomena of interest (such as opportunities for learning specific processes) and shapes a particular view of what evidence counts in constructing claims. The contributions brought together here invite readers to explore the processes involved in developing and studying educational innovations, and to undercover the interdependent conceptual and epistemological actions, processes and practices of instructors, programme developers and students.Taken together, the book brings forward an argument related to the reflexive turn – the understanding that researchers in the social sciences construct, rather than find, phenomena of interest. Therefore, this book creates the potential to examine not only the logic-in-use developed by different researchers, but also to examine the complex nature of particular phenomena of interest to the researcher themselves. This book was originally published as a special issue of Pedagogies: An Educational Journal.
