We designed an interactive virtual reality (VR) application to provide a controlled and yet unpredictable environment for the development of classroom management skills. The simulated environment allows teachers in training to interact with virtual students in realistic and meaningful ways. The VR application allows rich verbal interaction by using artificial intelligence (AI). Initial findings suggest it is a successful proof of concept. In this paper, we focus on the technical implementation. Predictions on educational effectiveness and the educational challenges of pre-service teacher education are discussed. Future developments include rigorous testing and incorporating non-verbal communication based on a multi-dimensional interpersonal behavior model.
