Many pedagogical counsellors (PCs) are destabilised by the resistance, in various forms, that novice teachers display during their counselling sessions. It is in this context that we propose TGRIS, a peer-training method, with a virtual reality interview simulator, designed to help PCs become aware of their own emotions, and deal with them, when confronted to a resistant novice teacher. The novice teacher is simulated by an embodied conversational agent (ECA) that is piloted by other, more experienced PCs. They can trigger the sentences, gestures and the emotional state of the virtual novice teacher. This tool has the particularity of using sentences that were collected from real-life problematic interviews. The PCs themselves transcribed and analysed their own counselling sessions in order to synthesise them. Three experimentations lead with 12, 17 and 3 PCs that showed the potential of the TGRIS technology-enhanced training sessions.
