Construcción de la Función Integral y Razonamiento Covariacional: dos Estudios de Casos

Abstract The aim of this paper is to characterize how high school students build the integral function concept in the context of a teaching experiment using applets, and designed according to a hypothetical learning trajectory. Five out of fifteen students were chosen, which have participated in the teaching experiment and shown different moments of reflective abstraction process, to carry out a study of cases. Our results indicated three characteristics for building the integral function concept: (i) not identifying the relationship between a bound of an interval and the value of the area und...
