Using (post) qualitative methodology located within a critical postmodern theoretical frame, I will examine the intersection(s) and borders of the field of mathematics education and the posts (post-structural, new materialist, post-humanist, post-qualitative). The “field” in this research will be considered a fluid space that shifts and responds as “new” research is brought into it. The research questions that guide this study are: 1. What are the taken for granted, expectations and norms of these spaces? 2. How are post theories being used/taken up within mathematics education? 3. How are the borders and boundaries of the field of mathematics education shifting in response to these theories and methodologies?
