Descripción de la transformación de conceptos básicos en un curso de transición aritmética álgebra en un experimento de enseñanza

Abstract

This work arises within of a qualitative research guide by the teaching experiment methodology, where non-participant observation represent a tool for building data from the triangulation of three information: sources sound and video recordings, notes of the trainees (co-research interns) and notebooks of the group observed. Consist on describe in dense, careful and detailed way the resignificance of multiplication and division as unit change of a mathematics students group, to give an account of the consolidation of a learning environment with the recursive nature of the dimensions: (1) teaching experiment strategies; (2) problem solving; (3) community of practice; (4) mathematical object, and to consider the following description levels: level 1: empirical with the fragments of transcription (data); level 2: data theorizing; level 3: inferences with theorizing and the empirical, to verify the relation of the results obtained with the empirical information.
