Una experiencia de capacitación en etnomatemática

El presente trabajo describe las experiencias de capacitación, llevadas a cabo en la ciudad de Pdcia R. Sáenz Peña, provincia del Chaco (Rep. Argentina), en el marco del Programa de Actualización y Perfeccionamiento 2008 en servicio a los docentes de la provincia en el nivel medio y superior. Mediante la documentación narrativa se pretende compartir tiempos, espacios y recursos para que los colegas puedan compartir con las autoras lo que pasa y pasó en ellos cuando tuvieron un primer acercamiento académico con la etnomatemática. La propuesta apunta amalgamar enseñanza con investigación, aproximándose hasta el punto de delinear un modelo de enseñanza cuya base fundamental es la investigación, que nutre a la acción y ayuda a los profesores a teorizar acerca de su enseñanza.

Symmetrical freedom quilts: the ethnomathematics of ways of communication, liberation, and art

Symmetrical Freedom Quilts may be considered as links between mathematics, history, ethnomathematics, and the art of quilting. A quilt theme is a pedagogical way to integrate mathematics, art, and history in an interdisciplinary approach. This article combines an ethnomathematical-historical perspective by elaborating a history project related to the Underground Railroad. This work will allow teachers to develop classroom projects that help students to better understand geometry, especially concepts of symmetry and transformations. One of the objectives of this project is to stimulate student’s creativity and interest, because quilts may be considered as cultural and mathematical expressions of student’s daily life.

An investigation of the mathematical elements of the Dai culture south-west Yunnan province, China

Dai ethnic mathematical culture is an important part of Dai ethnic culture. Mathematical elements show in their daily life. Through a research project of the Yunnan Dehong Dai people in southwest China, We collected the first-hand information, tried to do a small investigative study, and collected mathematics teaching resources that is useful to primary and secondary schools students on mathematics learning  in this minority areas. Keyword: Dai ethnic; Mathematical culture; Primary and secondary schools; Teaching resources.

El problema social y cultural de la población sorda en el aprendizaje de las matemáticas se minimiza con la intervención del profesor

Este artículo tiene como objeto de investigación el aprendizaje y como objeto matemático el concepto de función con estudiantes sordos de educación básica y media, con el propósito de mostrar cómo el problema social y cultural que tiene esta población para el aprendizaje de las matemáticas puede ser minimizado mediante la intervención del profesor, a partir de secuencias didácticas de enseñanza y la asistencia de un entorno informático. Para ello, se ha utilizado como marco teórico las situaciones didácticas de Brousseau y los registros de representación semiótica de Duval, y como metodología la Ingeniería didáctica.

Ethnomathematical research and drama in education techniques: developing a dialogue in a geometry class of 10th grade students

Ethnomathematical research, together with digital technologies (WebQuest) and Drama-in- Education (DiE) techniques, can create a fruitful learning environment in a mathematics classroom—a hybrid/third space—enabling increased student participation and higher levels of cognitive engagement. This article examines how ethnomathematical ideas processed within the experiential environment established by the Drama-in-Education techniques challenged students‘ conceptions of the nature of mathematics, the ways in which students engaged with mathematics learning using mind and body, and the ̳dialogue‘ that was developed between the Discourse situated in a particular practice and the classroom Discourse of mathematics teaching. The analysis focuses on an interdisciplinary project based on an ethnomathematical study of a designing tradition carried out by the researchers themselves, involving a search for informal mathematics and the connections with context and culture; 10th grade students in a public school in Athens were introduced to the mathematics content via an original WebQuest based on this previous ethnomathematical study; Geometry content was further introduced and mediated using the Drama-in-Education (DiE) techniques. Students contributed in an unfolding dialogue between formal and informal knowledge, renegotiating both mathematical concepts and their perception of mathematics as a discipline.
