Resumo: Mathematical modelling needs to be taught in realistic contexts. In this paper, we examine the potential of outdoor tasks that are solved by means of the digital tool MathCityMap to learn mathematical modelling stepwise. From a theoretical perspective, it can be assumed that the tasks have the potential to force the “Simplifying/Structuring” and “Mathematizing” steps to occur in an authentic way. In addition, MathCityMap supports the modelling process through hints and an answer validation. In a case study, we compare outdoor tasks with identical indoor tasks to examine in how far these theoretical considerations can be confirmed while using of the system. The results show that the outdoor tasks strongly force the simplifying/structuring step to occur and claim to work as precisely as possible while choosing a model and compensating for inaccuracies. Additionally, the MathCityMap system can support the choice of an exact but still simplified model by means of hints, and triggers an answer validation that might have the potential to make learners rethink the steps of the modelling cycle.

Neste artigo, examinamos o potencial das tarefas que são resolvidas em espaços exteriores, usando a ferramenta digital MathCityMap, para aprender o processo de modelação matemática passo a passo. Do ponto de vista teórico, pode supor-se que estas tarefas têm potencial para impulsionar as etapas “Simplificar/Estruturar” e “Matematizar” de uma forma autêntica. Além disso, presume-se que a ferramenta MathCityMap apoia o processo de modelação por meio de pistas e favorece a validação da solução. Num estudo de caso, comparamos tarefas resolvidas em espaços exteriores com as mesmas tarefas, mas resolvidas na sala de aula, para averiguar até que ponto essas considerações teóricas podem ser confirmadas na prática com o uso do sistema. Os resultados mostram que as tarefas resolvidas em espaços exteriores provocam fortemente a ocorrência da etapa de Simplificar/Estruturar e aumentam a exigência de trabalhar, com a maior precisão possível, na escolha de um modelo e no controlo de erros. Adicionalmente, o sistema MathCityMap permite apoiar, através de pistas, a escolha de um modelo exato, ainda que simplificado, além de fomentar a validação da resposta, mostrando ter potencial para levar os alunos a rever os passos do ciclo de modelação. APM - Associação de Professores de Matemática2021-12-31info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.48489/quadrante.23604eng2183-28380872-3915Ludwig, MatthiasJablonski, Simoneinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-05-09T20:47:45Zoai:ojs.revistas.rcaap.pt:article/23604Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-09T20:47:45Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
