En este artículo se presenta una investigación cuyo objetivo es caracterizar el proceso que sigue un grupo de alumnos universitarios para construir una serie numérica y determinar su convergencia. Para ello se analiza la actividad de dichos alumnos cuando resuelven una tarea en el aula habitual siguiendo el modelo propuesto por Pirie y Kieren. Esto ha permitido describir su progresión a través de los diferentes niveles de comprensión y comprobar la necesidad, en determinadas ocasiones, de realizar una vuelta a niveles inferiores mediante el mecanismo “folding back”. Se han encontrado manifestaciones del folding back de diferente naturaleza.
