VanLehn, Ohlsson, and Nason (1994) conjectured that simulated students have a great potential for teachers (better prepare for training), students (through collaborative learning with synthetic peers), and instructional developers (curriculum evaluation). Now, 20 years after their seminal work, we have built SimStudent, a computational model of learning that is beneficial to teachers, students, and researchers. In this talk, I demonstrate SimStudent’s ability for four tasks: (1) intelligent authoring, (2) student modeling, (3) data-driven model improvement for cognitive tutors, and (4) learning by teaching. I will also discuss future directions of SimStudent (broader applications and research opportunities) and simulated learners in general.
