Astronomy teaching and the Natural Sciences formative itineraries

In Brazil, Astronomy, due to its relevance and multidisciplinary character, has its concepts worked out throughout the stages that make up Basic Education, in the disciplines of Natural Sciences (NS), under the theme “Universe, Earth, and Life.” However, despite being present in the official documents that guide this stage of education, many studies point to a shallow approach in the classroom, mainly reflecting the teacher’s training and lack of quality teaching material. In this context, the changes introduced by the National Common Curricular Base (NCCB) brought as a novelty for High School the formative itineraries, whose objective is to provide students with content that allows for in-depth studies in a specific knowledge area. Thus, this research aimed to present a proposal for working on the teaching of Astronomy as an independent discipline in High School (HS), through an NS itinerary. Initially, the project was presented in the format of a pilot course that involved 33 High School students from a private school in São Paulo, lasting one school semester. In the end, the proposal was transformed into an Instructional Design (ID) resource for implementing the itinerary in a hybrid format. Based on the study carried out, it is hoped that the ID can provide subsidies to rescue the Astronomy teaching in HS, contributing to teachers having basic material to develop their activities in this significant knowledge area.
