This document presents an analysis of the interlaces used in the configuration of nine straw hat styles produced by the Colón - Génova community, Nariño, Colombia. These hats are known under the names of Común, Pintao, Gallineto-Granizo, Fino, Cuadros, Calado or Huecos, Costeño or Vueltiao, Bandera and Bird’s-Eye. The interpretation of the geometric thought employed in the design of these hats had like reference, between other authors, the methodologies proposed by Gerdes (1999) and Aroca (2009), that have been applied in the African continent and in South America.Besides, the existence of a logic of the construction became established, based in count strategies and organization that become evident in the crossed of the iracas or chullas. The evolution techniques were evidenced, which imply modifications in the basic fabric bearing to changes in the logic of the construction, resulting in the generation of new designs that search to fulfill to the needs of the present-day society. Craftsmen discuss the symmetry in their designs applying complex processes of estimate and count, which are tried to show. The symmetric figures correspond to triangles, quadrilateral and hexagons organized in stripes that fulfill properties of congruence, similarity and parallelism, being this a language of the researchers interpretation validated upon showing the results to academic communities.

Una aritmética existe por necesidad de una actividad huma-na y solo tiene sentido en el intercambio de los productos que genera o moviliza. El objetivo de esta investigación fue analizar las aritméticas en un sector del municipio de la Paz, departamento del Cesar, Colombia. Se identificaron, a la vez, los procesos y los algoritmos que emplean personas adultas, al hacer cálculos en algunos oficios y se determinó el grado de participación de los niños en estas actividades. He aquí justamente lo problemático, a que se hace referencia, cuan-do se dice que la matemática tiene sentido si se vincula con la realidad. La metodología empleada fue básicamente cua-litativa de tipo etnográfica, cuyas estrategias de recolección de datos consistió en 17 entrevistas informales de periodos cortos, observaciones no participantes de actividades y el empleo del google earth, como herramienta de localización de la actividad, dentro de un mapa. Los resultados muestran que es posible determinar cuándo el niño o niña se vincula, de manera concreta, a las actividades de su entorno socio-cultural próximo, en el sentido de comprender los procesos y los algoritmos de los cálculos empleados en ellas.

It is the arhuaca knapsack a fertile pre-colombian object in beauty and development of ancestral geometric thought. Due to its wealth, three are the perspectives of analysis presented in this article, in the presence of the designs complexity that provides them configuration and beauty: 1. Reference is made about the development of the geometric-symbolic thought when elaborating the knapsack. 2. A detailed analysis of the ethno-mathematic processes which are incorporated when knitting the traditional figures of the lateral part of the knapsack is presented, next an analysis of the gauzes is made and, finally, an examination is realized of the designs shown in the bottoms of the knapsacks, divided into three categories: bottoms that define spirals, those that define concentric rings and those that combine concentric rings and traditional figures. 3. Some reflections on the educational contributions of the ethno-mathematic developed by the arhuacas women in the backpacks are presented; these have to do, among others, with the importance of the color when developing geometric thought, and with the inaccuracy that exists in the measures and their similar consequences towards the development of similar scholar geometric concepts.

Aroca Araújo, Armando | 2008-01

This paper presents the synthesis of a methodological proposal in ethnomathematics as a result of three years of research, whose primary objective was to develop a plan for teaching geometry to the Arhuacos indians of the Sierra Nevada de Santa Marta, Colombia, taking into account the mathematical thinking which is included in the weaving of their “mochilas” and the relationship with their culture and history. The title of the research work is “A proposal for teaching geometry from a cultural perspective. Case Study: Indigenous Arhuaca Community. Sierra Nevada of Santa Marta, Colombia”. This methodology provides some guidelines to take into account when choosing the literature and the objective of ethnomathematic studies, and a way to determine the social and cultural meanings of such an object (basic inquiry of ethnomathematics). It also shows a way of how such an object could be mathematically analyzed and a general form of transposing didactically these research findings in different cultural contexts. Accordingly, this research is a new alternative for undergraduate and graduate students and researchers who are interested in ethnomathematics.
