As an extension of the former SimStudent project, we have further developed SimStudent as a simulation of human student's learning. Now, we can use SimStudent to conduct various controlled studies to explore cognitive theories of effective learning and teaching. SimStudent can be used as a teachable agent that can be embedded into a learning environment where students learn by teaching SimStudent.

Model tracing tutors are known to be very effective, but only at a cost of developing an underlying well-designed cognitive model. Hence a naïve question: can we build such a cognitive model much easily? The goal of this project is to build a machine-learning agent (called SimStudent) that can learn cognitive skills (a cognitive model of the target task) by observing model solutions demonstrated by an author. Integrated into CTAT, we have built an intelligent authoring tool for building Cognitive Tutor. Also affiliated with the Pittsburgh Science of Learning Center (PSLC) |

How to teach geometry theorem proving with construction? Here, by "construction," we mean adding points and segments into a problem figure by compasses and a straightedge as a part of a proof. Two major findings from this project:
