Análisis de las actuaciones de los alumnos de 3· de BUP en la resolución de problemas que comparan áreas de figuras geométricas

Resumen

This paper is a case study which intends to analyze and compare the performance of two pairs of 3rd BUP students when solving two mathematics problems in which the areas of geometric figures are related. The analysis and comparison of the performance of both pairs has been conducted from a two-fold perspective, the knowledge that students use during the problem-solving process, and the control they show over this process. For this, the protocol analysis technique has been used, by means of video recordings of the problem-solving processes.
