Resumen:	Esta ponencia comenta los resultados obtenidos a través de la aplicación de un cuestionario sobre energía a estudiantes universitarios de carreras no físicas, con el fin de relevar sus concepciones antes de la enseñanza del tema en el contexto de una experiencia educativa innovadora. Las respuestas dadas por los alumnos fueron volcadas en una base de datos que permitió su tratamiento cuanti y cualitativo, elaborándose para el caso de las preguntas abiertas, categorías emergentes de las propias expresiones de los estudiantes. Los resultados al definir el concepto evidenciaron los aprendizajes realizados por los alumnos en instancias previas de su formación, pero en la resolución de situaciones problemáticas, particularmente en la justificación de las opciones cerradas, mostraron la utilización de nociones de sentido común.
