Insertion of Contemporary and Modern Physics in classroom: a teaching learning sequence on radioactivity

Abstract

After more than two decades of justifications on the insertion of Modern and Contemporary Physics in the high school Education, the current challenge regards to how this content can be inserted in the classroom in an interesting and innovative way. Recent research reveals that despite a significant accumulation of recent academic research, whose purpose is to assist teachers pedagogically, few are grounded and proposed theoretically seeking to investigate how this integration happens. In this sense, we present a teaching-learning sequence on the topic of radioactivity, forged in the theoretical and methodological assumptions of Design-Based Research and a Teaching-Learning Sequence that, when implemented in public schools in the south of Bahia, produced the relevant knowledge to be shared with the community on teaching physics. Forged in our assumptions, the proposal allows teachers and researchers to understand questions about how, when and why, in fact, the inclusion of Modern and Contemporary Physics can occur in a non-traditional way. Therefore, the importance of this proposal is revealed to the high school of physics as it translates its ability to transform the theoretical demands on the curriculum and methodological innovation in the practical interventions in the classroom. We add that the availability of the necessary sources to find lesson plans, quizzes, texts, videos of teaching-learning sequence, shows the contribution of this work for teachers and researchers, in particular, to improve the scientific learning of students in the Basic Education.
