El objetivo de este estudio es analizar la conceptualizacion que tienen tres alumnos acerca del perimetro, area y volumen para determinar en que estadio del desarrollo de la comprension del proceso de medida, segun Piaget, se encuentra cada uno de estos estudiantes. Se aplico un cuestionario, en el primer semestre academico del 2007, a un grupo de alumnos de segundo semestre de Diseno Industrial. Los tres alumnos se seleccionaron porque presentaron dificultades en la comprension de los temas tratados en la asignatura de Calculo. Se encontro que los sujetos estudiados no se encuentran en el estadio superior de desarrollo de comprension de la medida; esto es un obstaculo para la solucion de problemas de calculo, relacionados con perimetro, area y volumen. This article shows the results of a study aiming at analyzing the conceptualization about perimeter, area and volume constructed by three university students in order to determine the development stage of comprehension of the process of measure of them, according to Piaget’s theory. A questionnaire was applied to a group of students of the second semester of Industrial Design, in the first academic semester of 2007. Three students were selected because they presented difficulties in the comprehension of the topics treated in Calculation subject. Results show that the target subjects are not in the high stage of development of comprehension of measure. This is an obstacle for solving calculation problems, in relation to perimeter, area and volume topics.
