In this work, we design, implement and analyze a didactic sequence for the teaching of the basic topics of special relativity theory in high school. The sequence proposes a series of situations, specially designed to allow the emergence of the central aspects of special relativity. The conceptualization process is investigated from the point of view of the theory of conceptual fields of Vergnaud. By means of a careful analysis of classroom student productions we detect the key theorems-in-action they use, evidencing that most of conceptual errors are of pre-relativistic nature. This leads us to a reformulation of the sequence, which promotes the conceptualization of Galilean relativity and the principles of the special relativity. This previous step aims at bringing to students a firm basis to address the more complex aspects of the subject.
En este trabajo se trata de relacionar los orígenes del Enfoque Basado en Competencias (EBC), la construcción del concepto de competencias, el sustento que brinda este enfoque a los cambios propiciados por el CONFEDI, y la relación entre competencias y resultados de aprendizaje. Se discuten los cambios observados en los procesos de enseñanza y de aprendizaje en experiencias realizadas en el Departamento de Ciencias Básicas de FRLP, UTN.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
