ESTUDIO COMPARATIVO DE LA ESTIMACIÓN DE CANTIDADES CONTINUAS QUE HACEN LOS ESTUDIANTES DE SECUNDARIA Y FUTUROS MAESTROS.

In this paper we analyze the results and processes used by third-year secondary students and prospective elementary teachers in estimation tasks of continuous quantities of length, surface, capacity and mass. The results show no differences between both groups of students. Both are good estimators of length and surface but underestimate capacity and mass. No big differences are detected in the processes and strategies used, except a higher and more effective use of formulas in the case of prospective teachers. [ABSTRACT FROM AUTHOR]
