| الملخص (بالإنجليزية): |
The focus of this research is the concept of median, which has received scarce interest in previous research. We analyse the open responses given by 518 Mexican students from Educación Secundaria (Junior) and Bachillerato (Senior) Secondary Education to a problem involving the computation of median. Using some ideas from the ontosemiotic approach, we classify the responses, taking into account the central tendency measure used, and describe the students' semiotic conflicts. We use the chi-square test to study possible dependence between responses and students' group. We observe better results in computation in Educación Secundaria students but better competence to select the best representative value in Bachillerato students. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): |
El foco de este trabajo es el concepto de mediana, sobre el que la investigación previa es escasa. Analizamos las respuestas abiertas de 518 estudiantes mexicanos de Educación Secundaria y Bachillerato a un problema abierto de cálculo de la mediana. Utilizando las ideas del enfoque onto-semiótico, clasificamos las respuestas según la medida de tendencia central utilizada y describimos los conflictos semióticos detectados. Mediante el test chi-cuadrado estudiamos la relación entre el tipo de respuesta y el grupo de estudiantes. Observamos mejores resultados entre los alumnos de Secundaria en el cálculo y mayor capacidad para elegir la medida de tendencia central más representativa en los alumnos de Bachillerato.
