Este estudo intenta analisar as práticas de pesquisa com alunos referente à área e perímetro na Educação Básica, quanto aos seus objetivos, metodologias de ensino e de pesquisa e suas inferências. Para tanto, analisamos três bases de dados: (a) Biblioteca Digital brasileira de Teses e Dissertações (BDTD); (2) Catálogo de Teses e Dissertações da Capes (CTD) e últimos dez anos do Encontro Nacional de Educação Matemática - ENEM. Perante essa investigação, evidenciamos que os estudos estão concentrados na região Sudeste do país; em sua maioria, são dissertações; e que não há elementos para suscitar um crescimento ou decrescimento das pesquisas nos últimos anos. Elencamos, ainda, a forte ênfase nas compreensões e manifestações dos alunos quanto aos conceitos de área e perímetro, bem como o foco em tarefas e atividades na configuração de metodologias de ensino e de pesquisa. Além disso, apontamos que muitos avanços são descritos de forma genérica, o que inviabiliza nossas considerações e produções na temática. Por fim, consideramos que este mapeamento pode contribuir para pesquisadores e docentes que ensejam adentrar na temática área e perímetro na Educação Básica, potencializando que diferentes formas de pensar tais conceitos possam vir à tona em pesquisas futuras.
Context: Although the use of video has been consolidated as a growing proposal in the classroom, there is no evidence of studies emphasising video production to construct mathematical knowledge of area and perimeter in basic education.. Objective: Analysing the contributions of the creation of videos by Powtoon in addressing areas and perimeters to the education of Grade 7 students at an elementary school in the countryside of São Borja, RS, Brazil. Design: An action research proposal is developed. Setting and participants: Six Grade 7 students from a rural school in São Borja/RS, Brazil. Collection and analysis: The research steps were 1) Application of a questionnaire; 2) Creation of the videos in four moments: a) Conversation with the students and presentation of the proposal, b) Research on the topic, c) Creation and finalisation of the videos, and d) Dissemination of videos; 3) Individual conversation about the answers in the beginning survey. Data analysis was based on content analysis. Results: The following are listed: 1) Visualising the understanding and development of students in relation to the concepts of area and perimeters; and 2) Technology, video and mathematics education, discussion of how students relate to technology and video in the classroom. Conclusion: Students employed effort in creating the videos and elaborated more deepened comprehensions on areas and perimeters. However, it should be noted that the students’ video production is associated with the traditional class model, leading us to question how the classes have been organised in basic education.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
