This book presents an overview of seventeen forms of inquiry used in curriculum research in education. Conventional disciplinary forms of inquiry, such as philosophical, historical, and scientific, are described, as well as more recently acknowledged forms such as ethnographic, aesthetic, narrative, phenomenological, and hermeneutic. Interdisciplinary forms such as theoretical, normative, critical, deliberative, and action research are also included. These forms of inquiry are distinguished from one another in terms of purposes, types of research questions addressed, and the processes and logic of procedure employed in arriving at knowledge claims.
