The main feature of B-4 is the “black box” with curtains and theatrical lighting, making the space ideal for performative language teaching and learning. This classroom provides modular furniture such as movable chairs to support flexible configurations so that students can engage in small and large group interactions. The room can be configured so that the class faces a side monitor and two glass boards, or faces forward, auditorium-style. Instructors can project from their own device or the installed laptop to either the monitor or the large-screen projector. Room capacity is 49.
