Resumo: This article presents an analysis of the content of geometric transformations in three collections of mathematics textbooks for high school selected by the last Programa Nacional do Livro Didático (PNLD). In this analysis, we sought to identify how the geometric transformations of translation, reflection, rotation and homotetia are presented, what are the tasks proposed on the content and the assignments for teachers who use these books. The analyzes were constituted from literature review of task, including problem situation, and exercise. It was found that there was a lack of deepening in some units of the analyzed books, the absence of a significant number of problems instead of exercises and the scarcity of suggestions for a more significant teacher’s performance at High School.

Nesta análise, buscou-se identificar de que maneira as transformações geométricas de translação, reflexão, rotação e homotetia são apresentadas, como são as tarefas propostas sobre o conteúdo e as atribuições destinadas aos professores que utilizam esses livros. As análises foram constituídas a partir das noções teóricas de tarefa, incluindo exercício e problema. Constatou-se a falta de aprofundamento em algumas unidades dos livros analisadas, a ausência de um número expressivo de problemas, em vez de exercícios, e a escassez de sugestões para uma atuação mais significativa do conteúdo pelos professores no Ensino Médio.Editora Unimontes2020-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.periodicos.unimontes.br/index.php/emd/article/view/287110.46551/emd.e202055Educação Matemática Debate; v. 4 n. 10 (2020): jan./dez.; 1-192526-6136reponame:Educação Matemática Debateinstname:Universidade Estadual de Montes Claros (UNIMONTES)instacron:UNIMONTESporhttps://www.periodicos.unimontes.br/index.php/emd/article/view/2871/4363https://www.periodicos.unimontes.br/index.php/emd/article/view/2871/3346https://creativecommons.org/licenses/by-nc-sa/4.0/deed.pt_BRinfo:eu-repo/semantics/openAccessNakamura, Paulo Henrique Souza Pazuch, Vinícius2021-06-30T17:36:20Zoai:ojs2.periodicos.unimontes.br:article/2871Revistahttps://www.periodicos.unimontes.br/index.php/emdPUBhttps://www.periodicos.unimontes.br/index.php/emdrevista.emd@unimontes.br||2526-61362526-6136opendoar:2021-06-30T17:36:20Educação Matemática Debate - Universidade Estadual de Montes Claros (UNIMONTES)false
