Abstract: A computerized method for providing a meaningful response in an intelligent tutor. The method includes the steps of receiving an input from a user solving a problem and determining if the input violates at least one consistency rule. The consistency rules are rules implemented to allow a constraint of the input to be evaluated and compared to a fundamental rule set for the problem. The fundamental rule set includes a plurality of principles that impose the constraints on a resulting solution. A student's mistake is applied to the consistency rules to allow the artificial intelligence program to respond to the answer by either providing a necessary principle overlooked by the student, or allows the program to, at a minimum, generate feedback to say something educationally useful to the student. This can be done even when buggy rules have failed to match and provide a rationale for the mistake.

Abstract: In a given environment where a user may work, play, or otherwise interact, such as the environment provided by a system comprising computer hardware and software, the present invention provides a method, computer program product, and system for teaching reinforcing concepts, principals, and other learned information without requiring user initiation of a learning sequence. Learning or reinforcement occurs by presenting “learning frames” in the environment automatically without requiring user initiation of the learning sequence. The user of the environment receives these intrusive or non-intrusive opportunities for learning while doing other tasks within the environment and may be interrupted from the task at hand and be required to respond to the presented learning frame or may simply have the opportunity for learning without requiring interruption of the task at hand according to the implementation of the present invention.

Abstract: Providing methods and systems for a computer-aided group-learning environment, where a number of users can interact and work on a subject together. The system and method can monitor and analyze users' inputs. The analysis process can identify a user's performance on the subject, and can understand some of the user's traits, such as confidence level and learning attitude. The system can include an interaction controller, which sets a duration of time for the users to communicate in a dialogue environment. Working on the subject in a group and working alone can be intertwined. For example, the users first work on the materials generated individually, and then solve the problem together in a dialogue environment. During the dialogue session, the interaction controller can provide hints to the users. The system can also include a user registry, which restricts the users who can use the embodiment to work on the subject.
