Abstract: This article focuses on the role of teaching experiment in the mathematics
teacher education practice and the research on teacher’s learning. First, the theoretical
ideas supporting the integration of the professional tasks’ resolution and the specific
activity system in the design of learning environments in mathematics teacher education
programs are presented. Secondly, findings of the research allow identifying some
features on what and how pre-service mathematics teacher learn in these learning environments.
Finally, we try to show the dependence between different roles of mathematics
teacher educator (practitioner, designer and researcher).
Keywords: teacher learning, teaching experiment, building of knowledge, interaction.
