Tres enfoques de la investigación sobre concepciones alternativas

In the last years the researchers on Science Education have given preferent attention to student's conceptions. Studies have been carried out and their interest is still growing. Our purpose in this paper is to give an approach to three ways of focusing the question; the «alternative conceptions», the «ways of reasoning» and the «causal mental models» approaches. Our goal is to compare them and show, without being exhaustive, some of their findings and future spectatives.
