espanolEl objetivo de esta investigacion es estudiar la forma en la que estudiantes de Educacion Primaria resuelven problemas de generalizacion de patrones. Para ello se ha analizado el nivel de exito, las estrategias utilizadas y la progresion de 106 alumnos de 3o, 4o, 5o y 6o de Educacion Primaria resolviendo un problema de generalizacion de patrones. Los resultados obtenidos muestran que los estudiantes con mayor exito comienzan con estrategias aditivas y despues cambian a estrategias funcionales, que invertir el proceso presenta una mayor demanda cognitiva y que muy pocos estudiantes son capaces de expresar la regla general algebraicamente. El analisis de la progresion de los estudiantes nos ha permitido definir descriptores de una trayectoria de aprendizaje que ayuda a diagnosticar la comprension de los estudiantes y a describir su progreso en terminos de crecimiento a traves de diez niveles de desarrollo. EnglishThe objective of this research is to study the way in which students of Primary Education solve problems of generalization of patterns. For this we analyzed the level of success, the strategies used and progression of 106 students in 3rd, 4th, 5th and 6th degree of Primary Education solving one problem of generalization of patterns. The results obtained show that the most successful students begin with additive strategies and then change to functional strategies, that reverse the process has a higher cognitive demand and very few students are able to express the general rule algebraically. The analysis of students’ progression has allowed us to define a descriptors of learning trajectory that help to recognize the students’ understanding and to describe their progress in terms of growth through ten levels of development.
