Whereas Natural User Interface technological devices, such as tablets, are bringing physical interaction back into mathematics learning activities, existing educational theory is not geared to inform or interpret such learning. In particular, educational researchers investigating instructional interactions still need intellectual and…

This paper proposes a learning based method that can automatically determine how likely a student is to give a correct answer to a problem in an intelligent tutoring system. Only log files that record students' actions with the system are used to train the model, therefore the modeling process doesn't require expert knowledge for identifying…

This paper looks at the analysis leading to and design of a Web-based "hint system." The hints are designed to help middle-grade teachers participating in a mathematics professional development effort, called InterMath, achieve a high degree of success when working open-ended mathematical investigations. The model upon which InterMath is…

The integration of test-banks for computer-based testing, textbooks, and electronic lecture notes in first-year mathematics courses has changed the way mathematics is taught at Bennett College (Greensboro, North Carolina). Classes meet in two electronic classrooms each with 27 computers on a local area network and a projection system. An…

This paper describes a college math and computer science educator's experience integrating multimedia materials in classroom instruction. It serves as a "tutorial" for non-computer science educators considering adding multimedia presentations to their instruction. The paper covers: the time commitment for developing and integrating multimedia…
