This article aims to analyze the development of didactical knowledge of teachers attending an in-service course focusing on statistical representations and investigations, two fundamental aspects of statistics education. This is a statistics course in a specialization program for middle school mathematics teachers, including 13 participants. The data collected was obtained from sessions by a logbook, audio recordings, and document collection and by interviews. The course was structured to articulate didactic knowledge from activities directed to teaching practice. The results show that the teachers deepened their knowledge of statistical representations and how to teach them. About statistical investigations, the teachers emphasize the importance of valuing these activities for the development of citizens who are critical and capable of dealing with information.
