The International Study Group on
Ethnomathematics was founded in 1985 by math educators Gloria Gilmer, Ubiratan
D'Ambrosio, Gil Cuevas, and Rick Scott. Since that time it has sponsored programs
and business meetings at the annual conferences of the National Council of Teachers
of Mathematics (U.S.A.) and at the International Congress of Mathematics Education.
In 1990 ISGEm became an affiliate of the U.S. National Council of Teachers of
Mathematics.
What is ethnomathematics?
The term was coined by Ubiratan
D'Ambrosio to describe the mathematical practices of identifiable cultural
groups. It is sometimes used specifically for small-scale indigenous societies,
but in its broadest sense the "ethno" prefix can refer to any group --
national societies, labor communities, religious traditions, professional
classes, and so on. Mathematical practices include symbolic systems, spatial
designs, practical construction techniques, calculation methods, measurement
in time and space, specific ways of reasoning and inferring, and other
cognitive and material activities which can be translated to formal mathematical
representation. The ISGEm strives to increase our understanding of the
cultural diversity of mathematical practices, and to apply this knowledge
to education and development.
