Potencialidades dos recursos mediacionais propostos em um curso de astronomia para professores

Abstract

This research addresses the inclusion of Astronomy in formal education, following the National Common Curricular Base (BNCC) and focusing on teacher training. Although the BNCC suggests an introduction to astronomy, this results in knowledge deficits for the majority of students. Elementary School teachers, mostly trained in different areas, often lack the necessary training to teach Astronomy. The objective is to contribute to reflection on the need to transform training processes into continuing training courses for Astronomy teachers in basic education. The focus is on teachers' interactions with mediating objects, culminating in the construction of an Astronomy mini-course aimed at training these professionals. The analysis is based on the properties of the mediated action, highlighting the irreducible tension between the agent and the mediating environment during this action. The mini-course, following proposed teaching phases, incorporates physical and virtual mediational resources. The analyzes emphasize the interactions between teachers and mediating objects throughout the course and the constructions of meaning resulting from these interactions. The flexibility of the course allows teachers to choose teaching sequences according to their needs, adapting to the specific context of each group. The potential of mediational resources aims, at the end of the mini-course, to provide teachers with the confidence to use these resources in the classroom, promoting richer and more engaging learning for students. The proposal highlights the relevance of astronomy not only as an expansion of scientific knowledge, but also for understanding the role of the Earth in the cosmic context, strengthening its integration into the school curriculum according to the BNCC. In summary, the mini-course seeks not only to transmit specific knowledge, but also to instigate reflection, active participation and the construction of meanings by teachers. It is expected that, in the end, teachers will feel able to approach astronomical topics in a dynamic and contextualized way in their pedagogical practices, contributing to a richer and more stimulating education.
