Abstract
En este artículo se propone una nueva forma de enseñanza de los problemas propios de la llamada “regla de tres” con dos o más magnitudes, actualmente basada en dos hipótesis físicas. Se analizan los distintos métodos de resolución enseñados de la regla de tres compuesta, sistemas sin fundamento basados en la intuición en contra de la deducción que caracteriza a la ciencia matemática. El nuevo método propuesto de resolución se apoya en la “Primera álgebra de magnitudes”, el cual se explica y fundamenta. Se realiza un estudio estadístico de la eficacia didáctica de todos los métodos con una muestra de 97 estudiantes y se exponen los resultados.
This article proposes a new way of teaching the problems of the so-called «rule of three with magnitudes», currently based on two physical hypotheses. The different methods of resolution taught from the compound «rule of three with magnitudes» are analyzed, systems based on intuition against deduction that characterizes mathematical science. The new proposed method of resolution is based on the “First algebra of magnitudes”, which is explained and logic reasoned. A statistical study of the didactic effectiveness of all the methods of rule of three with magnitudes is carried out and the results are presented.
