Neural imaging to track mental states while using an intelligent tutoring system.
Hemodynamic measures of brain activity can be used to interpret a student's mental state when they are interacting with an intelligent tutoring system. Functional magnetic resonance imaging (fMRI) data were collected while students worked with a tutoring system that taught an algebra isomorph. A cognitive model predicted the distribution of solution times from measures of problem complexity. Se...
متن کاملUsing Neural Imaging and Cognitive Modeling to Infer Mental States while Using an Intelligent Tutoring System
Functional magnetic resonance imaging (fMRI) data were collected while students worked with a tutoring system that taught an algebra isomorph. A cognitive model predicted the distribution of solution times from measures of problem complexity. Separately, a linear discriminant analysis used fMRI data to predict whether or not students were engaged in problem solving. A hidden Markov algorithm me...
متن کاملCasual Collaborations while Learning Mathematics with an Intelligent Tutoring System
We have started exploring and facilitating natural collaborations between students sitting in contiguous computers. We implemented a mechanism to facilitate this kind of social interactions, instead of struggling against it. By allowing students to "force" specific problems they want, one student can pull up the math activity that another student is going through in their computer, thus capital...
متن کاملUse of Unsupervised Clustering to Characterize Learner Behaviors and Affective States while Using an Intelligent Tutoring System
This paper presents results from a preliminary analysis of interaction and human observation data gathered from students using an Aplusix, an intelligent tutoring system for algebra. Towards the development of automatic detectors of behavior and affect, this study tried to determine whether it was possible to identify distinct groups of students based on interaction logs alone. Using unsupervis...
متن کاملAn Intelligent Tutoring System
As students learn about logic circuit design, they come across understanding concepts of Boolean Algebra. For some students, dealing with complex logical expressions could be a frustrating experience that may obstruct understanding as well as the development of the required design skills. Intelligent Tutoring Systems (ITS) could provide an excellent one-on-one support to improve conceptual and ...
