Diseño y evaluación de una secuencia topocéntrica para la enseñanza de las fases lunares en nivel secundario

Abstract

The design and evaluation process of a teaching-learning sequence about the lunar phases phenomenon is described based from the implementation of a Design-based research (DBR). The proposal was designed using the topocentric reference system in order to favor the construction of an explanatory model based on the observation of the Moon´s motion across the sky. The sequence was implemented in a second year of high school, being evaluated through the analysis of students' productions, class registration, and individual interviews. The results obtained show a favorable evolution of students' knowledge, including the possibility of relating the phenomenon with what they can observe daily in the local sky. Conclusions about the sequence and contributions to the teaching of astronomy at the secondary level are presented.
