    Comparative study of van-Hiele model and theory of Pirie and Kieren. Two alternatives for understanding mathematical concepts
    (POLICIA NAC COLOMBIA, 2017-10-01) Londono Cano, Rene Alejandro; Jaramillo Lopez, Carlos Mario; Esteban Duarte, Pedro Vicente; Londono Cano, Rene Alejandro; Jaramillo Lopez, Carlos Mario; Esteban Duarte, Pedro Vicente; Universidad EAFIT.

    This paper is a result of theoretical character, derived from a doctoral study in the frame of Mathematics Education, and its proposal is to describe important similarities and differences between the model of van-Hiele and Pirie and Kieren theory, and which have been theoretical frameworks of some educational experiences for understanding mathematical concepts. Initially, some backgrounds are considered in context itself, and after to be compared through descriptions and the respective nomenclature that each postulated level exhibits and so for characterizing them in order to achieve the respective conclusions. So, it is about to highlight some elements to argue the relevance of some theoretical framework or another one, according to any research purposes considered within the framework of the understanding of mathematical concepts.

    A Curricular Guide to Understand Some Geometrical Concepts on the Context of the Coffee
    (FUNDACION UNIV CATOLICA NORTE, 2016-04-19) Gonzalez Molina, Juan David; Santa Ramirez, Zaida Margot; Londono Cano, Rene Alejandro; Gonzalez Molina, Juan David; Santa Ramirez, Zaida Margot; Londono Cano, Rene Alejandro; Universidad EAFIT.

    In this article a curricular guide to progress in the levels of understanding is presented, a summary of the characterization of the understanding performed for each of the participants and the evolution of the evaluation rubric called Descriptors of Category by Level, which objective was to help three students of rural zones of a municipality of Antioquia (Colombia), in the analysis of the understanding of the geometrical concepts of perimeter and area and the independence of their measures within the context of the agriculture of coffee. In order to present this situation the theoretical framework, the subject background and the methodology are showed. Finally, some fragments of the analysis of the understanding of the participants and the final version of the rubric are published, which is preceded by a short summary of the moments occurred before making it.

    Distance-Virtual Education: Development and Characteristics in Mathematics Courses
    (FUNDACION UNIV CATOLICA NORTE, 2016-05-01) Sucerquia Vega, Edison Alberto; Londono Cano, Rene Alejandro; Jaramillo Lopez, Carlos Mario; de Carvalho Borba, Marcelo; Sucerquia Vega, Edison Alberto; Londono Cano, Rene Alejandro; Jaramillo Lopez, Carlos Mario; de Carvalho Borba, Marcelo; Universidad EAFIT.

    The distance-virtual learning is a field that permanently transforms itself and allows the creation of new educational programs in different fields of knowledge and educational levels. In this sense currently is conducted a research called ``Interaction Processes for Producing Mathematical Knowledge in a Student Group with Media in Virtual Distance Learning'', aimed at educating a PhD student and contributing to this field with theoretical and methodological perspectives in Mathematical Education in the context of the program of virtual education called Ude@,through a study of qualitative-approach cases. This article deals with some analysis, reflections and significant characteristics of the teaching-learning processes of mathematics in this type of virtual environments, through the proposal of strategies that identify those interaction processes that allow producing mathematical knowledge in virtual-distance-education courses.
