A1 Peña-Trapero, Noemí A1 Vasquez Suárez, Kena A1 Rodríguez Rivera, José Antonio A1 Becerra Mena, Ana Fátima A1 García de Paz, Sergio K1 Estudio - Métodos AB With the aim of helping to enrich teacher training processes, using an approach based on Practical Knowledge and Practical Thinking (Schön's knowledge-in-action), the present paper strives to explore and understand the relationships between espoused theories and theories-in-use (action theories by Argyris) of a group of seven pre-school teachers involved in a process of in-service training based on Lesson Study, a powerfulmethodological tool to identify, contrast and review such theories both autonomously and cooperatively. The conclusion reached is that this training strategy is a rich proposal for the questioning of teaching theory and practice, and, in consequence, for the reconstruction of more unconscious Practical Knowledge, albeit with some circumstantial and personal nuances.
