Filed:

Jun 19, 2001

Appl. No.:

09/884743

Inventors:

Kenneth R. Koedinger - Pittsburgh PA

Assignee:

Carnegie Mellon University - Pittsburgh PA

International Classification:

G09B 700

US Classification:

434322, 704270, 704255

Abstract:

Methods and systems are provided for tutoring a student in solving a problem described in the form of a dialog with a student involving questions posed to the student and analysis of student responses. The method employs a student model for receiving and diagnosing student input and a tutorial model for deciding what new questions to plan to ask the student. The method comprises the following steps: receiving the diagnosis in a tutorial processing module; generating an agenda including at least one question; applying at least one tutorial strategy to the diagnosis; and, providing feedback to the student based on application of the tutorial strategy given the current context as indicated by the agenda data structure. In certain aspects of the method, at least one knowledge remediation dialog and/or at least one knowledge construction dialog can be applied to generate dialog between the tutor and the student. System embodiments are also provided that incorporate the functions of the methods for tutoring a student.

G09B 7/00

Abstract:

The present invention relates generally to a system and method that bring together the advantages of computer games and the physical world to increase engagement, collaboration and learning. The system and method can be used with a myriad of physical setups and can be used for many different content areas in education. In one embodiment, a mixed reality interaction is facilitated with an EarthShake™ game presented on a display. The game is synchronized with a tangible interface comprising a physical object and a sensor capable of detecting a change in the condition of the physical object. The system and method help kids discover scientific and other learning principles while experimenting with real objects in a physical environment supported with audio and visual feedback. Students interactively make predictions, see results, grapple with disconfirming evidence and formulate explanations in forms of general principles.

Abstract:

A computer-implemented method includes, in one aspect, obtaining data specifying one or more expressions for a problem to be solved and an action that changes a state of the problem when applied to the one or more expressions, identifying one or more features of the one or more expressions, identifying a precondition for applying the action that changes the state of the problem, identifying a sequence of operator functions, and generating a production rule based on the identified one or more features, the identified precondition, and the identified operator function.
