Wayang Outpost: Intelligent Tutoring for High Stakes Achievement Tests

چکیده
We describe Wayang Outpost, a web-based ITS for the Math section of the Scholastic Aptitude Test (SAT). Wayang Outpost has several distinctive features: a large breadth of problems with multimedia animations and sound in the help, problems embedded in narrative and fantasy contexts, alternative teaching strategies for students of different mental rotation abilities and memory retrieval speed. We present evaluations of the tutor that lead to conclusions of effectiveness, which depend on the interaction of teaching strategies and cognitive abilities. A student model built from student interactions with the tutor is described.
