While research on the impact of a Eurocentric curriculum has often focused on marginalized populations in developing nations, it is paramount that scholars also examine the impact of this curriculum on students in the Global North. To this end, this paper begins by first defining and then critiquing what is often referred to as the "Eurocentric curriculum", and how standard Eurocentric content, such as Eurocentric mathematics and its pedagogical practices may alienate learners from their families, societies, and cultures. It will then suggest an alternative approach, "Ethno-mathematics" introduced by D'Ambrosio (1985), and will apply this concept to educational outcomes in both South Africa and the USA. The paper concludes with a brief discussion of how these cultural imbalances within a school's curriculum, if not corrected, may negatively impact the academic success of all students, particularly the marginalized.
