Ensinando dilatação dos sólidos por investigação utilizando experimentação

Abstract

The teaching of phisicshas been and withn the methodologies it is possible to simulate students and make teaching more challenging. The investigative teaching can, through experiments be extremely attractive to students. Thus, an approach will be madecorrelating the teaching of solid expansion friom na investigative perspective in two teaching modalites: the remote the face-to-face. Within the teaching modalities and the flexibility of physics, an experiment developed in a low-cost prototype is worked on, which through heating this wire is possible to achieve a result demonstrating the dilation in practice. Due to the great flexibility of adapting the experiment, it is possible to analyze the remote application that took place in times of social isolation due to COVID-19, in 2021, and compare it with an application that took place in person in 2022. Executed according to na investigativeteaching sequence about solid expansion in the 2nd grade of high school in a public school in the state of Minas Gerais. Thus, a bibliographic research was carried out, and after these surveys, a field research was carried out, which ainmed to cultivate the autonomy of the individuals that integrate the presente study. The research was carried out from na analysis of the modalities of remote teaching and faceto-faceteaching. Both applications happened with the same didactic and investigative seuqence, distinguished in some diferences and similarities presente in the two categories. Given this analysis, among the participating students, the results were similar and the capacity of undertanding between them for teaching the solid expansion was satisfactory. In the classes small, because the students do not have the means to communicate with the teacher and /or with their classmates.
