Engaging tutor learning experience


Learning with educational software such as Intelligent Tutoring Systems can be boring (despite their demonstrated effectiveness). This project aims to address this issue by designing and evaluating a novel form of interaction for solving middle-school algebra problems. Working with two design and development interns, John Britti (Georgia Tech) and Xiran Wang (CMU), we have designed the drag-and-drop equation solving ITS and have tested the effectiveness of the software on student learning of algebra concepts, equation solving skills, and student engagement/motivation. We have been using data and teachers’ feedback to further re-design the interface and the model used.
