Dificultades para Codificar, Relacionar y Categorizar Problemas Verbales Algebraicos: dos estudios con estudiantes de secundaria y profesores en formación

Solving verbal problems by transfer implies the activation of other, previously solved problems by means of the analogies perceived between these and the ‘target problems’. Two related studies are conducted to analyse what features students focus on to codify problems and to build analogies among them when sorting tasks are proposed. Quantitative and qualitative techniques were used in the analysis. First, we analysed how different science problem characteristics influence secondary students’ task performance. A high proportion of participants were not able to perceive suitable analogies...
