Abstract(s)
Este estudo insere-se no âmbito da Geometria e pretende compreender a influência dos
recursos didáticos utilizados no reconhecimento de propriedades e relações geométricas em figuras
planas.
De acordo com o objetivo do estudo formulamos duas questões orientadoras que se articulam
entre si.
- Que fragilidades apresentam os alunos, no reconhecimento de propriedades geométricas em
figuras planas?
- Que contributos resultam da utilização de materiais manipuláveis, na visualização espacial e
investigação de propriedades geométricas?
Com este estudo pretendemos reunir informação que contribua para aprofundar o
conhecimento sobre o raciocínio geométrico dos alunos.
Em termos metodológicos segue um método de investigação misto, com recolha de
informação qualitativa de natureza interpretativa e quantitativa, na modalidade de estudo de caso. A
recolha de dados foi realizada numa turma de 4.º ano do ensino básico onde foi desenvolvida a
experiência didática.
A informação recolhida resultou da observação direta e as fontes dos dados foram as produções
dos alunos, as notas de campo, registos fotográficos, vídeo e áudio.
A docente assumiu o papel de investigadora e orientadora das tarefas propostas aos alunos
tendo estes desempenhado um papel ativo na construção do seu próprio conhecimento.
Os resultados obtidos permitem evidenciar as fragilidades dos alunos no reconhecimento de
propriedades geométricas de figuras planas em diferentes posições. Destacam ainda os contributos
da utilização da Mira e do Tangram, no estudo da simetria e no desenvolvimento da visualização
espacial para a concretização de aprendizagens concretas, motivadoras e significativas.
This study falls within the scope of geometry and intends to understand the influence of using teaching resources in the identification of geometrical properties and relationships in plane shapes. According to the aim of the study, we formulate two guiding questions that articulate together: - What are the students' weaknesses in the identification of geometrical properties of plane shapes? - What are the contributions resulting from using manipulatives in spatial visualization and in the study of geometrical properties? With this study we intend to gather information that contributes to deepening knowledge about the geometrical reasoning of the students. In terms of methodology it follows a joint research method with the collection of qualitative information with interpretative nature in conjunction with quantitative information, in a case study mode. The data collection was carried out in a 4th grade primary school class where the learning experience has been developed. The information gathered resulted from direct observation and the data sources were comprised by the students’ productions, field scores as well as photographic, video and audio records. The teacher took both the roles of researcher and adviser for the tasks proposed to the students, having them played an active role in the building of their own knowledge. The obtained results allow to evidence the students' weaknesses in identifying geometrical properties of plane shapes placed in different positions. They also highlight the contributions of using the Sight and the Tangram in the study of symmetry and in the development of the spatial visualization, to achieve concrete, motivating and meaningful learnings.
