In this paper I analyze interactions within a chat with mathematics teachers. The analysis was focused on the roles of the trainer to interact in this kind of environment. A case study is done and the chat is considered the unit of analysis. Learning is understood as an immersive way of interaction and participation in the constituted virtual environment. The research underscores the importance of the discursive dimension on the constitution of the trainer functions. These functions can be: creativity to elaborate activities; initiative to motivate continuously the individuals; asking for examples, engagements and collective reflections, analyses and contrasts; ratification and relativity of ideas and discoveries; asking for information from practice and promoting self-reflective processes.
