Resumo: In the present study we propose a new look at rescuing the condition of radioactivity as a natural and present phenomenon in our lives going beyond the accidents and calculations present in the teaching of radioactivity. This notion was object of a formative proposal in a course of Degree in Chemistry in a public institution of Pernambuco in action research form as strategic. We aimed to analyze the conceptions of licensees about Radioactivity Environmental through the use of conceptual maps produced before, at end and three months after the end of the training proposal. In general, we noticed that there was a gradual evolution of radioactivity concepts, especially regarding corrections of the mistakes identified, as well as the consolidation of some information referring to the environmental perspective. Through these results, we believe in contributing to new teaching practices based on radioactivity concepts of future chemistry teachers.

Tal noção foi objeto de uma proposta formativa num curso de Licenciatura em Química numa instituição pública de Pernambuco na forma de pesquisa-ação como estratégia. Tivemos como objetivo analisar as concepções dos licenciandos através do uso de mapas conceituais acerca da Radioatividade antes, ao final e três meses após o término da proposta formativa sobre a temática Radioatividade Ambiental. De modo geral, notamos que houve uma gradual evolução especialmente quanto às correções dos equívocos identificados, bem como a consolidação de algumas informações alusivas à perspectiva ambiental. Por meio desses resultados, acreditamos estar contribuindo para o desenvolvimento de novas práticas de ensino com base nos conceitos de radioatividade para futuros professores de química.Universidade Federal de Santa Catarina2019-05-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/alexandria/article/view/1982-5153.2019v12n1p5510.5007/1982-5153.2019v12n1p55Alexandria: Revista de Educação em Ciência e Tecnologia; v. 12 n. 1 (2019); 55-841982-5153reponame:Alexandria (Florianópolis)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/alexandria/article/view/1982-5153.2019v12n1p55/40021Copyright (c) 2019 Alexandria: Revista de Educação em Ciência e Tecnologiainfo:eu-repo/semantics/openAccessda Silva, Roberta MariaAquino, Kátia Aparecida da Silvada Silva, Suely Alves2019-05-27T19:13:40Zoai:periodicos.ufsc.br:article/53727Revistahttps://periodicos.ufsc.br/index.php/alexandria/oai1982-51531982-5153opendoar:2019-05-27T19:13:40Alexandria (Florianópolis) - Universidade Federal de Santa Catarina (UFSC)false
