  1. The role of language in ethnomathematics Does the language make it ethnomathematics?

  2. Tamsin Meaney University of Otago • Uenuku Fairhall Te Kura o Te Koutu • Tony Trinick University of Auckland

  3. Ethnomathematics • Borba (1990) suggested that ethnomathematics is ‘[m]athematical knowledge expressed in the language code of a given sociocultural group’.

  4. Language and culture • Levi-Strauss (1963, p296) stated that ‘a society consists of individuals and groups which communicate with one another.’ • Geertz (1975) suggested that when an experience is described in language, meaning is added. In analysing an experience in order to describe it, an individual is constrained by their linguistic repertoire.

  5. In te reo Mäori, runga can mean ‘up’ but in different situations can also mean ‘above’, ‘top’ and ‘south’ and are linked to ‘life’, ‘standing’ and ‘Sky Father’ (Salmond, 1976).

  6. Changing the language which is used to describe the experience, whether it is a change in natural language or a change in register within a language will have an impact on how that experience is described and therefore what is valued within this experience.

  7. The mathematics register is the words and grammatical expressions which are used consistently to describe mathematical ideas • It is only when the mathematical ideas within an ethnomathematical activity are valued by discussants that the mathematics register will be deployed.

  8. Ethnomathematics in kura kaupapa • In kura kaupapa Mäori, ‘the pedagogy of these schools is based on, but not exclusively, Mäori preferred teaching and learning methods’ (Smith, 1990 p147-148).

  9. Children may only speak te reo Mäori at kura • Most of their outside kura experiences would be similar to their Pakeha peers

  10. Teachers at the kura value students outside kura experiences such as using money but also felt that traditional practices such as: Tukutuku, whakairo, ranga harakeke and naviagational skills could be used.

  11. Land Division • Land belongs to extended family groups • Share is dependent on the number of generations since title was recognised.

  12. At a family night in 2004, parents came as students to attend various classes and the children were assistant teachers. Describing land division using the language of fractions meant that for the first time many parents understood how their land share came about and understood how fractions operated.

  13. It relates to students’ backgrounds • It shows that mathematical concepts were incorporated into traditional activities • It makes the concept of fractions more than just a set of abstract ideas, • Discussing the activity using the mathematics register in te reo Mäori added another dimension which had not been apparent to the parents previously.

  14. Newness of te reo Tätaitai • Only developed since the 1980s • Few teachers use it with upper secondary students • Most teachers weren’t taught in te reo • Teachers in the earlier grades don’t know the te reo terms for some mathematical ideas

  15. If the class and its teacher were confident in discussing mathematics and had a sophisticated understanding of the mathematics then more culturally appropriate terms would develop.

  16. Like Terms in algebra • The term used in the new dictionary of mathematical terms, Te Reo Pängarau, is röpü meaning ‘grouping’. • Students in Uenuku’s senior classes coined the term, whakawhänau, meaning ‘making families’.

  17. It was through discussion of what was happening when ‘like terms’ were gathered together that the students felt that whakawhänau was more appropriate. This is because the connotations which this term invoked more readily fitted their understanding of what was happening.

  18. Discussion of Western mathematics in te reo tätaitai needs to be done in a way which makes use of the cultural connotations of the Mäori words.

  19. Conclusion • In discussing ethnomathematical activities thought needs to be given to the language used to discuss them. • The language will situate the activity within a set of cultural connotations. • The language should contribute to adding meaning rather than detracting from the meaning in the activity if described using another language or register.

  20. And does language make it ethnomathematics?
