This paper sets out to challenge thinking and practice amongst researchers in the field of inclusive education. It does this based on an analysis of published articles in the "International Journal of Inclusive Education" between 2005 and 2015, which identified topics and methodologies used in studies of inclusive education. The analysis highlights the fact that most of the studies are only concerned with certain groups of learners and that a limited number make use of collaborative, transformative approaches. It is argued that focusing only on some students, rather than on all, is contrary to the principles of inclusive education. At the same time, given the emphasis of inclusion on enabling the participation for all students, it is argued that more research needs to adopt collaborative approaches that set out to change thinking and practice in the field. Illustrative examples from articles that used such approaches are discussed to highlight their potential benefits.
