  1. Utilidad de los modelos de viscoelasticidad en el aprendizaje de la ingeniería de materiales poliméricos

    Fombuena Borrás, Vicent; Boronat Vitoria, Teodomiro; Sánchez Nacher, Lourdes; García Sanoguera, David; Balart Gimeno, Rafael Antonio
    [EN] The present article makes a brief description about the simplest mathematical models of viscoelasticity:Maxwell Model and Kelvin-Voigt Model. However, these basic models have a number of limitations becauseit has considerable di erences from reality. Thus, the Burgers model is studied due to is an appropriatemodel to study the viscoelasticity in polymers. By solving a practical case, the usefulness for studentsof mathematical models related with process such as creep or relaxation and their understanding andprediction of the mechanical behaviour has been revealed

  6. Matemáticas Dialógicas. ‘Yo soy de mates’

    Díez-Palomar, Javier
    [EN] In this article I introduce the dialogic mathematics approach, drawing on three successful educationalactions (SEAs): interactive groups, family involvement in mathematics, and dialogic mathematics gathe-rings. The main aim is to illustrate through these examples how SEAs, which previous studies have provedthat contribute to improve mathematics learning, work. I conclude that looking at interactions may openthe oor to better understand how we learn mathematics, while the creation of dialogic spaces based onsuch contributions may also be an opportunity to improve students' mathematics achievement.

  7. Los videojuegos como objeto de investigación incipiente en Educación Matemática

    Albarracín, Lluís; Hernández-Sabaté, Aura; Gorgorió, Núria

In particular the methodological basis that was used to build a consensus teaching model, in-cluding environmental and human factors that determine the dynamics of coastal sediments, is included.The development of the consensus model had the collaboration of experts in coastal sedimentology andecosystems as well as teachers of di erent educational levels (from Primary to University), which helpedselect the ages to which the modelling could be applied, helping also in developing the graphical model thatwould be the base for a future educational intervention

  19. Atando cabos entre contexto, competencias y modelización ¿Es posible enseñar ciencias a todas las personas?

    Izquierdo Aymerich, Mercè
    [EN] The recommendation to teach science in context, through Models, to acquire competences, applies toall teaching without di erentiating between the basic and the non-compulsory levels. But the purpose oflearning science in the stage of compulsory education (for what and why teach) is very di erent from thatof the non-compulsory stage, when science students have chosen this subject among others. Therefore, toteach science to all, the curriculum of the basic cycle must be designed with more freedom, so that theschool sciences provide resources to understand the functioning of the world in which we live, to be ableto speak of it...
