POTENTIALLY SIGNIFICANT TEACHING SEQUENCE FOR TEACHING SPECTROSCOPY MEDIATED BY A VIRTUAL LEARNING ENVIRONMENT IN HIGH SCHOOL AT THE MILITAR COLLEGE OF SALVADOR-BA

Abstract

This research is based on the recognition that teaching Physics at the secondary level faces challenges, especially in the study of the interaction between light and matter, such as in spectroscopy. The use of technological resources can streamline the process and promote meaningful learning, as proposed by Ausubel and colleagues. The overall objective is to develop a teaching sequence for teaching spectroscopy in a virtual learning environment (VLE), with the following specific objectives: promoting meaningful learning, reviewing the literature on spectroscopy teaching and its fundamental concepts, and applying techniques that enhance understanding of these concepts. The methodology adopted was a hybrid, structured in two stages. The first stage involved a documentary, historical, and qualitative bibliographic review on spectroscopy, Ausubel's theory, and teaching in VLEs. In the second phase, a teaching sequence was developed for high school classes using the Brazilian Military College System's online learning environment (VLE). The results include a state-of-the-art assessment of the topics covered and the development of a teaching sequence in four stages: contextualization, presentation of basic concepts, problem-solving of experimental interpretation, and evaluation. In the latter phase, students developed comparative tables of experimental measurements, produced simplified reports, and recorded videos describing the experience. Student motivation and interest were observed, evidenced by active participation in forums and increased classroom engagement.
