This article reports on an evaluation of the results of a development program for secondary school mathematics teachers. Twenty classroom sessions with students in the second year of secondary school were prepared and videotaped. During the sessions, crucial topics on the curriculum were addressed and the students were given a series of non-routine problem situations to solve. Their solutions required elementary mathematics and creativity, rather than advanced knowledge. Subsequently, ten sessions with teachers were organized and filmed. After solving the same problems as the students, the teachers watched the videos of the student sessions. The teachers then discussed prepared questions to guide their reflections on their practice, based on the problem-solving they and the students had done. The analysis suggests that relevant changes occurred in the teachers' conceptions of teaching and learning mathematics, along with improvement in their knowledge of mathematics.
