Este es un estudio exploratorio con enfoque metodológico, centrado en la caracterización de las funciones lineales inversas, como funciones biunívocas e invertibles. El objetivo propuesto consistió en identificar algún tipo de dificultad estructural en estudiantes de primer ingreso universitario al trabajar con propiedades de una función lineal inv...

In this exploratory research we analyze the structure sense evidenced by 33 secondary students (16-18 years old) in tasks requiring to reproduce the structure of given algebraic expressions. The expressions used were algebraic fractions related to algebraic identities. There were big differences between the students performance which allowed differ...

Resumen A raíz de las dificultades que presentan estudiantes de Educación Secundaria y Bachillerato cuando tienen que operar con igualdades notables, nos propusimos indagar sobre el sentido estructural que manifiestan un grupo de estudiantes de 1º de bachillerato al trabajar con expresiones algebraicas que involucran este tipo de igualdades. Con es...
