Overview
This website includes:

an elaboration of my theoretical orientations towards the field of mathematics education research itself: what constitutes the (im)possible, the (non)sensical, and the (im)proper.

an introduction to citation network research methods, a discussion of the quantitative methods used in this citation network analysis (forcedirected layout algorithms and Louvain modularity).

a detailed discussion of my research process from data sourcing to data processing and importing to map generation and bubble naming.

a list of possible uses of the maps for mathematics education researchers, graduate students, and professors.

the maps (citation networks) of the bubbles and foams (1970s2010s JRME, 2000s flm, 2000s ESM) which together constitute an atlas of mathematics education research as it has been and how it has evolved from the 1970s to today. These maps include both bubbles (microperspective of research foci) and foam (macroperspective of what the bubbles together constitute during each decade).

a virtual gallery that is a fullyinteractive art gallery presentation of the theories, maps, and comparisons made in the gallery. This was used in lieu of a powerpoint presentation at my dissertation defense.

The field of mathematics education does not exist per se, but rather is the product of many people writing around some (disparate) ideas that have congealed into the semblance of a thing that looks solid, that looks fixed, but really is a foam: a volatile substance made from many bubbles (foci) emerging, popping, merging, and splitting. Following in the genealogical tradition of Michel Foucault, I look back at the emergence of this field called mathematics education research to trace the emergence of foci of study. From the focus on teaching and learning and achievement differences in the 1970s to issues of inclusion, racial equity, and critical research methods in the 2010s, the foci of the field have not been fixed. This shift, the fluid nature of an evolving field gives me hope. What mathematics education research is is not a natural inevitability, but the product of human action, the collision of incident, orthogonal, and/or opposite forces, and its trajectory is tied to its origins yet not deterministically.
What has been done in the name of mathematics education research is not its natural inevitability but the product of these collisions of forces; this popping, merging, and splitting of bubbles, and certain foci have merely gained dominance, imbuing them with a state of presumed inevitability. Since there is no natural start/origin, there is no naturally inevitable conclusion/destination and the field can grow in new/different/unexpected ways. By looking at those articles published between 1970 and 2019 in the Journal for Research in Mathematics Education (JRME), as well as those published since 2010 in for the learning of mathematics (flm) and Educational Studies in Mathematics (ESM), I provide a tracing of a field called mathematics education research. By mapping the citation relationships of these articles and their references in their entirety, I will identify the bubbles of research in each decade of interest (5 from the JRME and 1 from each of flm and ESM). In addition, I will identify the bubbles that together constitute the foam of the field: the bubbles correspond to the different foci that, put together, share borders.
Borrowing an aesthetic sensibility from Jacques Rancière, I believe that the field, as it has been, limits what we can say is mathematics education research, what we can see as counting as mathematics education research, what we can think as mathematics education, and what we can do in the name of mathematics education research. These limits on what can be seen, said, thought, and done in the name of mathematics education research, what is (non)sensical, constitute a distribution of the sensible. The dissertation that accompanies this website serves as a perturbation of those sensible limits. Drawing on the genealogic process of Foucault, I celebrate the fact that what has been, and what currently is, is neither natural nor inevitable. Therefore, what can be in mathematics education research is limited only by our imaginations as a field.
