Enseñanza-aprendizaje del concepto del color con alumnos de escuela primaria

This research addresses the operational invariables used by children when they are forming up colors throughout a set of activities with the projection of colored lights on white surfaces. The research was carried out with a group of fourth grade Portuguese children from a public school. The activities were carried out once a week, for three consecutive weeks, in order to find explanatory models built in action by the children.The research relies on the theory of conceptual methods as a frame of reference to interpret children’s written and oral productions for all perceived explanation for each experience. The results are meant to contribute to improve the knowledge of children’s basic notions about the elements of the physical world and, thus, point out to teachers different ways of didactic approaches through experimental interventions.
