Resumo: | The present work is part of a broader academic master’s research, whose objective is to analyze the emergence of zones of the conceptual profile of entropy and spontaneity in a didactic sequence applied to chemistry graduates. We justify the use of the theory of conceptual profiles for its importance in considering different ways of thinking scientific concepts, which have pragmatic value in certain contexts, as well as the need to present this plurality in situations of teaching and learning in the classroom. This study is a clipping with the specific objective of analyzing the emergence of the zones of the conceptual profile of entropy and spontaneity from the informal and scientific conceptions of the students. The research was carried out with twenty students enrolled in the Physics-chemistry I course of the Licentiate degree in Chemistry of the Campus Acadêmico do Agreste of the Universidade Federal de Pernambuco, using an instrument composed of a single broad question, elaborated according to the literature recommendations: "the What do you mean by entropy?" The analysis showed the emergence of the three zones of the conceptual profile of entropy and spontaneity in students' answers, namely: perceptive/intuitive zone, empirical zone and rationalist zone. We highlight the occurrence of responses mostly associated with the idea of entropy as a degree of disorder of a system, in direct association with the question of the spontaneity of the processes by increasing entropy, which corresponds to the empirical zone. |

Justificamos a utilização da teoria dos perfis conceituais por sua importância em se considerar diversos modos de pensar conceitos científicos, que possuem valor pragmático em determinados contextos, bem como a necessidade de apresentar essa pluralidade em situações de ensino e de aprendizagem em sala de aula. Este estudo é um recorte com o objetivo específico de analisar a emergência das zonas do perfil conceitual de entropia e espontaneidade a partir das concepções informais e científicas dos estudantes. A pesquisa ocorreu com vinte estudantes matriculados na disciplina Físico-química I do curso de Licenciatura em Química do Campus Acadêmico do Agreste da Universidade Federal de Pernambuco mediante aplicação de um instrumento constituído de uma única e ampla pergunta, elaborada segundo recomendações da literatura: “o que você entende por entropia?”. A análise evidenciou a emergência das três zonas do perfil conceitual de entropia e espontaneidade nas respostas dos estudantes, a saber: zona perceptiva/intuitiva, zona empírica e zona racionalista. Destacamos a ocorrência de respostas majoritariamente associadas a ideia de entropia como grau de desordem de um sistema, em associação direta à questão da espontaneidade dos processos mediante aumento da entropia, que corresponde a zona empírica.Universidade Tecnológica Federal do Paraná (UTFPR)Guimarães, Cleiça Rafaela de AlmeidaSilva, Flávia Cristiane Vieira daSimões Neto, Jose Euzebio2019-07-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos pares, Artigos Originais, Artigos de Revisãoapplication/pdftext/htmlhttps://periodicos.utfpr.edu.br/actio/article/view/883610.3895/actio.v4n2.8836ACTIO: Teaching in Sciences; v. 4, n. 2 (2019); 15-29ACTIO: Docência em Ciências; v. 4, n. 2 (2019); 15-292525-892310.3895/actio.v4n2reponame:Actio (Curitiba)instname:Universidade Tecnológica Federal do Paraná (UTFPR)instacron:UTFPRporhttps://periodicos.utfpr.edu.br/actio/article/view/8836/6351https://periodicos.utfpr.edu.br/actio/article/view/8836/6352Direitos autorais 2019 CC-BYhttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2022-10-18T23:53:55Zoai:periodicos.utfpr:article/8836Revistahttps://periodicos.utfpr.edu.br/actio/PUBhttps://periodicos.utfpr.edu.br/actio/oaimarcelolambach@utfpr.edu.br||actio-ct@utfpr.edu.br||periodicos@utfpr.edu.br2525-89232525-8923opendoar:2022-10-18T23:53:55Actio (Curitiba) - Universidade Tecnológica Federal do Paraná (UTFPR)false |
