In elementary and secondary schools, as well as at university level, an increasing number of teachers are investigating their own professional practices. They undertake that because they feel the need of better understanding the nature of the problems that they face, in order to transform their practice and working conditions. This paper begins by briefly presenting the main characteristics of this activity as a research genre. Then, it describes the experience of a group of mathematics teachers and teacher educators, from several school levels, who are collectively carrying out an activity of reflecting about their investigations about their practices and presenting then to the professional community. And, finally, the article analyses what that work represented for the participants involved in this work.
