Alternative conceptions, metacognition and didactic integration of augmented reality in learning astronomy.
14:15 - 14:30
The Astronomy Diagnostic Test (Hufnagel et al. 2000) is an excellent tool to identify students' alternative conceptions about astronomy (although it has been used extensively as a pre and post test in subjects related to astronomy). However, in the ADT there are no questions that allow identifying conceptions about the distances and relative sizes of the sun and the planets of the solar system. Therefore, an instrument was developed to identify these alternative conceptions, and to support the metacognitive process of the students, by integrating it into a didactic sequence. Augmented reality resources on relative sizes and distances in the solar system were developed to facilitate learning using 3D digital models.
The didactic sequence was implemented during three semesters (2019 to 2021) in the 2nd year Physics of the Universe course with pre-service science teachers, achieving a high evaluation by the students, and significantly improving learning on this topic.
