Rutas cognitivas de futuros maestros ante una situación comparativa de razones desiguales

Javier Monje Parrilla, Bernardo Gómez Alfonso

Resumen

En esta investigación se analizan las rutas cognitivas que subyacen a las resoluciones de un grupo de futuros maestros ante una tarea de comparación de razones desiguales en el contexto de las ofertas comerciales. La revisión de la literatura y el análisis en profundidad de las componentes críticas de la tarea nos han permitido definir las dimensiones de análisis de las resoluciones. A partir de ellas hemos realizado un análisis cualitativo de corte interpretativo del cual se desprende que los participantes poseen un escaso desarrollo del pensamiento relativo. Un número importante de ellos presenta dificultades con la comparación de las cantidades relativas desiguales cuando estas se les presentan normalizadas de forma diferente y con distinto referente.

Palabras clave
