espanolA traves de la presente investigacion se logro disenar e implementar una estrategia de aula, por medio de la cual los estudiantes enfrentados a situaciones abiertas fueron capaces de abordarlas, utilizando de modo satisfactorio el nuevo modelo de resolucion de problemas. Es asi como la estrategia propuesta, que estructuro las clases de Fisica en torno a la tematica movimiento armonico simple, permitio secuenciar coherentemente los contenidos de la tematica, oriento y presento un modelo para solucionar problemas, destacando la argumentacion como eje metodologico que posibilito a traves de la fisiologia del texto elaborado por los estudiantes, la interrelacion de los conceptos, la produccion de razones y la elaboracion de conclusiones validas. A partir de los resultados obtenidos, se construyo la propuesta de los elementos que debe contener un modelo de resolucion de problemas a traves de la argumentacion como aporte a la didactica de la ensenanza de las ciencias. EnglishThrough the present investigation it was managed to design and to implement a classroom strategy by means of which the students who faced open situations were able to approach them by using the new model of problem resolution in a satisfactory way. So the strategy proposed that structured the Physics classes emphasized on the following thematic: Simple Harmonic Movement, which allowed to sequence the contents of the thematic coherently. Besides, it oriented and represented a model to solve problem emphasizing the argumentation like the methodological axis that made possible the interrelation of the concepts, the production of reasons and the elaboration of valued conclusions through the physiology of the text elaborated by the students. By means of the final results obtained, the proposal of the elements was constructed. This proposal must contain a model of problem resolution through the argumentation as contribution to the Didactics of the education of Sciences.
