Virtual reality offers an immersive, remote alternative to in-person teaching. We teach a Lean masterclass entirely in real-time virtual reality. By summer 2021, we had taught five masterclasses for 117 senior-level managers from more than 50 leading organisations. In these courses, participants located all over the world can interact with each other almost as in a physical seminar setting. Drawing on formal course evaluation surveys and personal experience, we discuss the appropriateness of real-time virtual reality as a teaching platform and the benefits and challenges of this approach. Based on our experiences, and taking into account the rapid ongoing technological development, we imagine that this form of teaching and learning will accelerate in importance and application.
