Los problemas de estimación en contexto real pueden utilizarse como iniciación en la elaboración de modelos matemáticos. En este estudio se recogieron los planes de resolución individuales de estudiantes (N=224) del grado de Maestro/a en Educación Primaria que se enfrentaron a una secuencia de problemas de estimación contextualizados. Posteriormente, esos mismos estudiantes trabajando en grupos (N=63), resolvieron los mismos problemas realizando mediciones y estimaciones in situ. Así, el estudio se centra en los denominados factores de complejidad, referidos a los aspectos de la resolución con los que se pretende obtener una estimación más precisa. El objetivo es determinar qué factores de complejidad enriquecen los planes de resolución individuales y cuáles son los que enriquecen las resoluciones grupales. Además, se identifica qué características del contexto real promueven que los estudiantes incluyan determinados factores de complejidad, tanto en los planes de resolución individual como en las resoluciones grupales. Los resultados permiten identificar el impacto del trabajo de campo en el proceso de resolución de tareas de estimación formuladas en contextos reales cercanos; en relación al conocimiento del profesor en formación, los resultados permiten identificar carencias en el conocimiento de las tareas matemáticas para la enseñanza.
