The North American chapter of the International Group for the Psychology of Mathematics Education (PME-NA) is a 501(c)(3) organization. The major goals of PME-NA are to promote the international exchange of scientific information in the psychology of mathematics education; to stimulate interdisciplinary research in this field with the cooperation of psychologists, mathematicians, and mathematics teachers; and to further a deeper and better understanding of the psychological aspects of teaching and learning mathematics and the implications thereof. Each year, the annual conference features talks by highly esteemed plenary speakers, presentations of current research from within the PME-NA community, and numerous opportunities to collaborate with mathematics education colleagues.
