Kécia Gomes de Moura, KéciaAna Emilia de Melo Queiroz, Ana Emilia2026-10-162026-10-162011-07-30https://repositorio.univasf.edu.br/handle/123456789/1559This paper describes the project and development of an educational interface in order to teaching additive and multiplicative structures. This teaching is accomplished through the manipulation (mediated by software) of Gerard Vergnaud diagrams, developer of The Theory of Conceptual Fields (MARGINA et al., 2000). Using the notation of diagrams proposed by Vergnaud allows to differentiate the various types of additive and multiplicative problems. This interface was developed in JAVA language, satisfying the requirements captured by paper prototyping and modeled using diagrams of UML (Unified Modeling Language).porhttps://creativecommons.org/licenses/by-nc/4.0/Engenharia de SoftwareSoftware EducativoTeoria dos Campos ConceituaisRaciocínio MatemáticoTrabalho de Conclusão de CursoCIENCIAS EXATAS E DA TERRA
