This article is part of a project that seeks to explain the conditions of teaching and learning mathematics in multigrade elementary schools. Based on studies of teaching mathematics and the contributions of ethnographic research, the article analyzes the process of managing six classes in which a teacher, experienced in one-room schools, mobilizes...

This paper points out the difficulties in adults with little or no schooling when teaching mathematics. Our objective is to contribute to the spread of didactic alternatives for adults regarding the conventional written representation of natural numbers by recovering their former mathematical knowledge from their daily lives. This kind of knowledge...

Article
In this paper, we analyze the arguments that secondary teachers made about the presence or absence of proportionality in several written problems and, through these, we explore the explicit knowledge of the teachers about the properties that define proportionality. For the study we designed and administered a questionnaire to 63 practicing mathemat...
Article
A partir de una experiencia de formación en didáctica de las matemáticas dirigida a maestros-formadores, se estudian las condiciones bajo las cuales la observación y el análisis de prácticas de enseñanza pueden adquirir un valor formativo. El curso se impartió en una modalidad semipresencial y se centró en el estudio de cuatro temas de matemáticas...
Chapter
El porcentaje es una noción matemática de frecuente uso social que, sin embargo, es difícil de comprender para los estudiantes; este hecho puede atribuirse a las nociones que le subyacen, la de razón, la de fracción y la de operador multiplicativo decimal, de las cuales hereda dificultades tales como la de comprender la relación entre medidas, dist...
Conference Paper

Se presenta un análisis de las condiciones bajo las cuales la observación y el análisis de prácticas de enseñanza de maestros de primaria y de secundaria pueden adquirir un valor formativo en sus procesos de actualización. Se destaca la dificultad para centrar la mirada en cuestiones relacionadas con el conocimiento en juego y se revisan algunos fa...
Article
Se analiza el uso que estudiantes de secundaria hacen de las razones, las fracciones y los decimales para resolver situaciones de porcentaje. Se destaca la necesidad de buscar formas en las que los estudiantes podrían acceder a una mayor articulación entre dichas nociones y, en particular, se pone de manifi esto la importancia de la noción de razón...

The role of the notion of ratio in the primary school mathematics, especially that of its link with the notion of fraction, are not clearly defined in the curriculum, at least in Mexican's one, nor in classroom teaching. We share the point of view that attributes these difficulties mostly to the genesis of these notions, as well as to that of its t...

Article
A didactical sequence for the learning of some aspects of the ratio notion is justified and the results of its application in a third grade class of elementary school are presented. The benefits of relating the study of multiplication of natural numbers with the study of ratio are emphasized. Finally, some elements for the analysis of the links bet...
