The aim of this paper is to show that the AVA possible the appropriation of concepts in geometry, spatial reasoning stronger and therefore offer a promising field for these tools to be a resource that promotes teaching emerged around the teaching / learning mathematics. RESUMO El presente artículo muestra una breve descripción de la metodología utilizada para el estudio de los cambios de actitud hacia las matemáticas en estudiantes de ciclo V, generadas bajo dos condiciones experimentales: La primera, El estudio, implementación y evaluación de un ambient...

In the development of research used a 2 x 4 factorial design of two variables: learning styles versus knowledge representation systems. The subject groups were obtained by applying the test of classifying them according to Kolb learning styles: assimilating, accommodating, diverging and converging. Through the development of tests determined the incidence ECAES with the knowledge representation systems (concept maps, graphs, frames networks and mentefactos). The working hypothesis was to determine whether significant differences in conceptual transfer between subjects according to their learning styles due to knowledge repr...

The main outcome was to determine the impact of the knowledge representation systems in a virtual learning environment using ECAES examinations as strengthening resources and reviewing of the knowledge. The learning styles were taking into account to process the information related to the results from the questionnaire based on ECAES examinations which were designed and assessed by the ICFES (Instituto Colombiano para el Fomento de la Educación Superior).During this research was implemented a 2 x 4 factorial design of two variables; learning styles and knowledge representation systems. The participants were classified by applying The Kolb learning style inventory; according to learning styles they were classified in Assimilators, accommodators, Divergers and Convergers. The knowledge representation systems used during the research were concept maps, conceptual graphs, conceptual mentefactos and frames. The objective of the research was to determine if there are significant differences in the conceptual transfer between students according to their learning styles and their knowledge representation systems used in the study of basic medical skills.The study revealed that 53% of the students were divergers (Reflective observation). The knowledge representation systems that allow students got the best findings were frames and conceptual mentefactos , although the results were not significant. The converger students got the best findings in this type of test, which is in line with KOLB’s approaches.Investigación llevada a cabo con estudiantes de medicina internistas en una institución de educación superior. Investigación de tipo cualitativo, con un diseño factorial 2 x 4 de dos variables, los estilos de aprendizaje y los sistemas de representación del conocimiento. Los participantes fueron clasificados mediante la aplicación de el inventario de estilos de aprendizjae de Kolb, de acuerdo con los estilos de aprendizaje se clasificaon en Asimiladores, Acomodadores, Divergentes y Convergentes. Los sistemas de representación del conocimiento utilizados durante la investigación fueron los mapas conceptuales, gráficos conceptuales, mentefactos conceptuales y marcos. El objetio de la investigaciónfue determinar si existían diferencias significativas en la transferencia conceptual entre los estudiantes de acuerdo a sus estilos de aprendizaje y sus sistemas de representación de conocimiento utilizados en el aprendizaje de las habilidades médicas básicas utilizando exámenes EAES como fuente de creación. El estudio reveló que el 53% de los estudiantes eran Divergentes (observación reflexiva). Los sistemas de representación del conocimiento que permiten alos esatudiantes los mejores resultados fueron marcos y mentefactos conceptuales, aunque los resultado no fueron significativos si existe una correlación
