Mathtutor is a free website designed to help 6th, 7th and 8th grade students learn math by doing. Supported by a 3-year grant from the US Department of Education, Mathtutor was developed at Carnegie Mellon University to provide remedial instruction to middle-school students through intelligent tutoring systems built with CTAT. The project includes a large number of problem sets (sequnces of problems revolving around similar problem-solving interfaces) and a full learner management system that enables teachers to create class lists, assign work to an entire class or an individual student, and view reports of student progress. Visit Mathtutor to learn more.
Carnegie Mellon University researchers Bruce McLaren, Dave Yaron, and Kenneth Koedinger utilized CTAT Flash tutors to investigate whether learning could be improved by personalized, informal language and worked examples in intelligent tutoring. For the first time, CTAT was used in a large-scale, web-based Pittsburgh Science of Learning Center (PSLC) study.
Researchers created a series of example-tracing tutors that help students design and optimize thermodynamic cycles, such as the Rankine cycle used in power plants.
