  8. Análise semiótico-psicanalítica de uma representação visual da burrice no ensino-aprendizagem de matemática

    Passos Lopes, José
    Abstract: This article aims to analyze a picture as a visual representation or sign of stupidity in teaching and learning mathematics, which was carried out with 23 pedagogy students with disturbing memories that can cause flaws in their reality tests. Two forms were analyzed, one with free associations of the figure and one with dissertations from the students, making up the semiotic-psychoanalytic reading of the data. The references used were the theory of signs, with Santaella's study of the matrices of languages and thought (visual and verbal); Pierce's theories of interpretants and perception; and psychoanalytic concepts. The results showed a...

  11. Obtención de fracciones de diseños factoriales a dos niveles con 32 observaciones

    García García, Javier
    Una de las aplicaciones fundamentales de la Estadística es el diseño de experimentos. En un diseño experimental se manipulan deliberadamente una o más variables (factores), para medir el efecto que tienen en otra variable de interés (variable respuesta). En un diseño factorial, es necesario medir la variable respuesta para dos o más valores de cada factor. En los estudios exploratorios una estrategia habitual es considerar solo dos niveles o valores en cada uno de los factores. A estos diseños experimentales se le denomina diseños factoriales a dos niveles. El número de observaciones que requiere cada diseño es una potencia de...

    Masoliver i Marcos, Guillem; Pérez-Sánchez, Modesto; López Jiménez, Petra Amparo
    [EN] The construction process of a viscometer, developed in collaboration with a nal project student, is he-re presented. It is intended to be used by rst year's students to know the viscosity as a uid property,for both Newtonian and non-Newtonian ows. Viscosity determination is crucial for the uids behaviorknowledge related to their reologic and physical properties. These have great implications in engineeringaspects such as friction or lubrication. With the present experimental model device three di erent uidsare analyzed (water, k etchup and a mixture with cornstarch and water). Tangential stress is measuredversus velocity in order to characterize all the uids...

  15. 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.

    Cárcamo, Andrea
    [EN] The aim of this paper is to present a proposal for teaching linear algebra based on heuristicof emergent models and mathematical modelling. This proposal begins with a problematicsituation related to the creation and use of secure passwords, which leads rst-year stu-dents of engineering toward the construction of the concepts of spanning set and span.The proposal is designed from the results of the two cycles of experimentation teaching,design-based research, which give evidence that allows students to progress from a situa-tion in a real context to the concepts of linear algebra. This proposal, previously adapted,could have similar results when applied to...

  19. Complex saddle points in the Gross-Witten-Wadia matrix model

    Álvarez Galindo, Gabriel; Martínez Alonso, Luis; Medina, Elena
    We give an exhaustive characterization of the complex saddle point configurations of the Gross-WittenWadia matrix model in the large-N limit. In particular, we characterize the cases in which the saddles accumulate in one, two, or three arcs, in terms of the values of the coupling constant and of the fraction of the total unit density that is supported in one of the arcs, and derive an explicit condition for gap closing associated with nonvacuum saddles. By applying the idea of large-N instanton we also give direct analytic derivations of the weak- coupling and strong-coupling instanton actions.

  20. Las sustancias expresivas y sus interrelaciones en la articulación de los significados del texto fílmico

    Jiménez Arias, Pedro Ismael
    Todo proceso de comunicación presupone la existencia de un código que establece correspondencias entre las señales que realizan los significantes y los significados que transmiten, así como las relaciones entre las entidades sígnicas así creadas. La comunicación audiovisual no cuenta con un código previo, sin embargo el cine o la televisión producen textos compresibles por sus espectadores. El discurso audiovisual se encuentra registrado en la imagen técnica que produce y reproduce distintos códigos cuya interrelación da lugar a los mensajes que pretende transmitir. La principal intención de este trabajo es construir un modelo de análisis que dé cuenta de la...
