Ítem Constitución del objeto fractal en estudiantes de grado séptimo: un experimento de enseñanzaDiaz Barreto, Brianna Lorena; Casallas Hernández, Liceth Andrea; Narváez Ortiz, Deissy MilenaIn this work he describes the constitution of the fractal object in a teaching experiment in which 60 seventh grade students (11-13 years old) participated, from an educational institution in Bogotá, Colombia. We designed a sequence of teaching episodes based on a phenomenological proposal of the fractal object that includes five metal objects that make up the concept: Self-similarity, recursion, scale factor, infinity, and fractal dimension. In the results, we identify the importance of experimentation to generate action schemes in students; we also emphasize the categorization of these schemes through mathematization.Ítem Constitución del Objeto Fractal en un Grupo de Estudiantes del Curso Transición Aritmetica Álgebra en un Experimento de EnseñanzaDíaz Barreto, Brianna Lorena; Casallas Hernández, Liceth Andrea; Romero cruz, Jaime HumbertoThis paper aims to describe the results of research associates for a couple of students to teachers of mathematics on the establishment of the fractal object carried out by a group of students. The proposal was developed in learning training space algebra arithmetic transition, curricular project LEBEM, of the Francisco José de Caldas District University, in a learning environment designed taking into account the own didactic phenomenology of current teaching realistic mathematics education. The results are obtained by using research methodology teaching experiment.Ítem Reflexión sobre la implementación de políticas etnoeducativas en la formación de docentes de matemáticas de la UDFJC(Universidad Distrital Francisco José de Caldas) León Sánchez, Ángel David; Díaz Barreto, Brianna Lorena; Sánchez Rincón, Julián Daniel; Casallas Hernández, Liceth Andrea
