The last teaching-learning stage in the education system is the doctoral programmes, which turn graduatestudents into researchers. This evolution involves writing a dissertation, but also being able to discuss research.However, training on spoken genres has not received much attention, and the interest has been mainly onmonologic prepared speeches. This paper focuses on a genre of interactive speech, the discussion session (DS)that follows the paper presentation, which is particularly challenging for novice researchers. We present alearner-led pedagogy for the teaching-learning of this genre that fosters thinking-based learning and multimodal awareness. It was implemented in a course of academic discourse for doctoral students in order to prove its effectiveness. We propose a process of active and collaborative deconstruction and construction of DSs to identify verbal and non-verbal resources and their interpersonal functions, so that novel researchers reflect on and integrate them in their repertoire.
