espanolEl presente articulo forma parte de un proyecto mas amplio que se intereso en senalar los procesos de ensenanza y de aprendizaje de estocasticos en la educacion especial. Aqui se presenta, de manera cualitativa, lo concerniente a la docencia de este nivel educativo. La perspectiva teorica considero tres ejes rectores: epistemologico, cognitivo y social. De las tres fases de la investigacion, en parte de la segunda enfocamos la introduccion de la nocion de distribucion de probabilidad para cuatro docentes en un escenario denominado estudio dirigido, con la instrumentacion de guiones de ensenanza y de bitacora; los datos se registraron con videograbacion y escritura en papel. Ademas, se aplico el organo operativo y la celula de analisis de la ensenanza. Los resultados conciernen a la adquisicion, de manera gradual por parte de las docentes, de las ideas de espacio muestra, medida de probabilidad, variable aleatoria (frecuencias relativas) y distribucion y simetria. EnglishThis article is part of a more extensive project aimed at analyzing stochastics teaching and learning processes in special education. The teaching of this educational level is presented here using a qualitative approach. From a theoretical perspective, three guiding axes were considered: the epistemological, cognitive and social axes. The larger study was divided into three phases. This paper will be focused partly on the second phase, particularly on the introduction of the probability distribution for four teachers in a guided study scenario, using teaching scripts and logbooks as instruments. Data was recorded in video and in writing. In addition, operational body and teaching analysis unit were applied. Results include the teachers’ gradual acquisition of the ideas of sample space, probability measure, random variable (relative frequencies), distribution, and symmetry.
