Comparación de la enseñanza de la geometría en los sistemas escolares chileno y francés

Este reporte trata de una investigación cooperativa cuyo tema es la comparación de la enseñanza de la geometría en Chile y en Francia (proyecto ECOS-CONYCIT). Después de definir nuestra metodología por zooms sucesivos, presentamos las mayores diferencias que encontramos entre los dos países. Estas diferencias conciernen a los ámbitos siguientes: la concepción de la geometría, los aspectos de la actividad matemática puestos en evidencia, la organización del aprendizaje, la extensión de los programas, la importancia dada a las aplicaciones de matemáticas y a la modelación. Los trabajos de C.Houdement y A.Kuzniak sobre los paradigmas geométricos nos permiten analizar las concepciones de la geometría.

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.
