Uso de um protótipo de uma célula solar como ferramenta pedagógica

Abstract

This study uses a solar cell prototype as an experimental teaching strategy to teach concepts related to the composition and functioning of a photovoltaic cell for generating electricity. The proposed approach seeks to overcome teachers' difficulties in explaining abstract concepts by using hands-on activities as a pedagogical tool, facilitating the understanding of the physical and chemical concepts involved. Furthermore, the research aims to raise students' awareness of this technology as an anchor for sustainability. The research was conducted at a public school in Fortaleza, Ceará, with second-year high school students. The process was developed in two stages: the first consisted of a brief contextualized lesson to elucidate the basic knowledge necessary to understand the topic, and the second involved experimentation with low-cost materials, complemented by questions that provided a connection between the two stages through meaningful learning, aligned with the principles of the BNCC. The results obtained were based on the parameters of a qualitative-quantitative study that included photographic records, observations of experimental activities, and data collection through questionnaires. These findings indicated greater student engagement and productivity in constructing their own knowledge. This process contributed to the students' conceptual understanding of the mechanisms involved in a solar cell
