O estudo da 1ª. lei da termodinâmica no contexto da máquina a vapor: uma proposta de sequência didática no enfoque Ciência-Tecnologia-Sociedade (CTS)

Abstract

Starting from the analysis of educational products from seven master’s thesis in the teaching of Physics, the following paperwork discussed the relationship between Science, Technology and Society (STS) from the perspective of the study of the first law of Thermodynamics (FLT). Noticing a gap in educational products that proposed a discussion about the FLT focusing on the STS, a Didactic Sequence (DS) was developed, assembling the educational product, which considered the interrelationships between the STS spheres putting more emphasis on the dyad Society-Technology (ST). Among other resources, the DS presents a case to be studied on the topic of public transportation - focusing on the city bus mode, involving views on technology, whose detailing was done using the aspects of technological practice. The validation of the DS was done in accordance with the process of Elaboration - Application - Re-elaboration (EAR). In this context, the application was run using the pair validation method, it was carried out through interviews with four professors of the Thermodynamics and Statistical Physics class of the National Professional Master's Degree in Physics Teaching in the Hub 24 of the Federal University of Juiz de Fora/Federal Institute of the Southeast of Minas Gerais, Juiz de Fora campus, semester 2021/2. The re-elaboration of the DS was carried out following the results from interviews which were analyzed using the method Content Analysis and stemmed in the rewriting of one of the proposals presented in the case to be studied, which is centered on the dyad Society-Technology.
