A construção conceitual é uma preocupação recorrente na pesquisa em educação científica e matemática. Este texto aborda uma discussão sobre a formação de conceitos no âmbito da ciência cognitiva e da cognição corporificada. Ilustra-se uma situação de ensino pautada nos conceitos de retas concorrentes, retas paralelas e retas transversais. A análise volta-se ao uso de metáforas em um ambiente de aprendizagem que potencializa a reflexão conceitual e o uso de smartphone em atividades de geometria. A implementação da atividade e a análise da escrita como forma de verbalizar cada conceito sugerem que em uma aula de matemática são possíveis novas formas de desenvolvimento conceitual, sobretudo por considerar que o pensamento dos sujeitos está cada vez mais impregnado pelas linguagens favorecidas pelas tecnologias digitais móveis. Os smartphones, em particular, reconfiguram o cenário e possibilitam o enriquecimento das interações e do campo imagético-metafórico no desenvolvimento de um conceito.
Background: Visualisation is a crucial skill for several everyday life activities and conceptual construction and development. Objectives: As it represents a substantial part of Euclidean geometry, this article addresses: the study and analysis of the relationships between angles formed from two parallel lines intersected by a transversal and the role of visualisation in the construction and development of geometric concepts imbricated in the mathematical relationships underlying the theme. Design: The methodological approach adopted was Design Experiments. Settings and participants: A teaching situation is presented, in which students from the 8th grade of elementary school at a state public school in Rio de Janeiro, Brazil, performed manipulations on the smartphone screen while carrying out an activity. Data collection and analysis: To analyse this activity, we selected events from a video obtained from the smartphone used by the students. Results: Through interactions and handlings, students visualised, analysed, and built the concepts of corresponding angles and collateral angles by studying a geometric object on the smartphone screen through the GeoGebra application. Conclusions: The geometric work mediated by mobile devices with touch screens enables the curricular reorganisation of Geometry and the articulation and the breaking of the hierarchy of concepts.
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.
