¿Cómo se mueve la Luna en el cielo? Evaluación de una secuencia para la construcción de un modelo topocéntrico para la explicación de las fases lunares

Abstract

The aim of this article is to present and evaluate a teaching sequence for a topocentric explanatory model of the lunar phases at primary school level. The model is based on the movement of the moon in the sky as observed by students from school or from their homes, rather than from outer space. The sequence includes explanatory diagrams and was implemented on a virtual test basis with three final-year primary school students. To evaluate the model, information was collected through the analysis of each student’s outputs, the recording of synchronous classes, and individual interviews. The results show a favourable evolution of students’ knowledge about the phenomenon and the possibility of relating it with what they observe in their own celestial environment.
