Institutional and instructional decolonizing mathematics education

In this theoretical essay, we respond to recent scholarship on decolonizing mathematics that asserts that so-called "Western" mathematics is inherently colonialist - that is, in service of the economic and political control of European or wealthy nations over countries of the Global South. Although generally sympathetic with that literature, we argue against some of its presumptions, in part, by distinguishing "Western" or academic mathematics from its recontextualization for schools. First, we argue that, although colonialist messages and values can be disseminated as part of that recontextualization, it is not clear that academic mathematics is inherently colonialist. Then, we offer a suggestive insight into what it might mean to decolonize school mathematics through a pedagogical approach based on research on native language learning, called the "subordination of teaching to learning." The approach uses tasks that invite learners to use their indigenous mental powers (or brilliance) through engaging in dialogic interactions with themselves and others about objects and relations among them. To illustrate the subordination of teaching to learning, we present an example of how learners use their learning powers to educate their awareness and build mathematical ideas and reasoning; thereby experiencing the joy of their intellectual efforts.
