The Assistment Builder: A Rapid Development Tool for ITS
Intelligent Tutoring Systems are notoriously costly to construct [1], and require PhD level experience in cognitive science and rule based programming. The goal of this research was to ease the development process for building pseudo-tutors [4], which are ITS constructs that mimic cognitive tutors but are limited in that they only work for a single problem. The Assistment Builder is a system de...
متن کاملThe ASSISTment Builder: Towards an Analysis of Cost Effectiveness of ITS Creation
Intelligent Tutoring Systems, while effective at producing student learning [2,7], are notoriously costly to construct [1,9], and require PhD level experience in cognitive science and rule based programming. The literature suggests [1,9] that it takes at least 200 hours of work to build 1 hour on ITS content. We have been engaged in building tools to reduce the development time, by allowing aut...
متن کاملRule-Based Cognitive Modeling for Intelligent Tutoring Systems
Rule-based cognitive models serve many roles in intelligent tutoring systems (ITS) development. They help understand student thinking and problem solving, help guide many aspects of the design of a tutor, and can function as the “smarts” of a system. Cognitive Tutors using rule-based cognitive models have been proven to be successful in improving student learning in a range of learning domain. ...
متن کاملTowards Enabling Collaboration in Intelligent Tutoring Systems
Intelligent Tutoring Systems have historically been shown [Koedinger, Anderson, Hadley & Mark, 1997; Morgan & Ritter, 2002] to be an effective means of educating an audience. While there is great benefit from such systems they are generally very costly to build and maintain. Currently it is estimated that 200 hours of time is required to produce one hour of Intelligent Tutoring Systems content ...
متن کاملCognitive Tutors: Lessons Learned
This article reviews the 10-year history of tutor development based on the advanced computer tutoring (ACT) theory (J. R. Anderson, 1983, 1993). We developed production system models in ACT of how students solved problems in LISP, geometry, and algebra. Computer tutors were developed around these cognitive models. Construction of these tutors was guided by a set of eight principles loosely base...
