Designing cognitive tutors and modeling behavior for ill-defined domains require innovative methods and techniques. We combine a top-down, theoretical approach with a bottom-up, empirical approach to develop a student model for the selection of aspect in French verbs. In performing this task, we design a new representation applicable to feature-driven ill-defined problem spaces and utilize tutoring scaffolds in order to elucidate the student thought process.

Each leverages modern 3D video game engine technology which allows high-fidelity simulation of new cultural settings, including representations of buildings, streets, art work, dress, voice, gestures, and more.

We now focus on the hypothesis that natural language dialogue is an even more effective way to support self-explanation. We have developed the Geometry Explanation Tutor, which helps students to state explanations of their problem-solving steps in their own words.

One relatively new use of games is to facilitate learning social or interpersonal skills such as conflict resolution by simulating human behavior with virtual characters. My work investigates students' social goals to understand how they help motivate students to acquire cultural understanding in BiLAT, one such system designed to teach cross-cultural negotiation skills.

The first edition of CATS took place in 2008 in conjunction with ITS2008, which was followed by a second edition, held in conjunction with AIED2009. As in the previous two years, the current workshop aims to continue the investigation of the way culture can be represented within the overarching goal of imparting knowledge via intelligent tutoring systems.

While cognitive tutoring has been successful in well-defined domains, much less work has been completed in cognitive tutoring in ill-defined domains. Skill assessment is one of the difficult challenges that that must be solved before cognitive tutoring can become a reality in these domains. Assessment formats commonly used by instructors in ill-defined domains do not always have a correct answer or follow a finite set of solution paths.

Our students have used it to analyze existing educational games and to create prototype educational games. The framework is built on existing components: a method for precisely specifying educational objectives, a framework for relating a game's mechanics, dynamics, and aesthetics, and principles for instructional design grounded in empirical research in the learning sciences.

We investigate how to support students in an on-line environment in acquiring cultural knowledge and intercultural competence by viewing clips from feature films from the target culture.

Technological solutions have been rare exactly because of the nonmainstream nature of their talk, and hence the difficulty in automatically recognizing their speech and responding to it with, for example, computer tutors.

We investigate how to support students in acquiring ill-defined skills of intercultural competence using an online environment that employs clips of feature films from a target culture. To test the effectiveness of a set of attention-focusing techniques (pause-predict-ponder) we created ICCAT, a simple tutor that enhances an existing classroom model for the development of intercultural competence.

This" cultural tutor", developed with the new Flash version of the Cognitive Tutor Authoring Tools system, assists students in reflecting more deeply and gaining greater cultural understanding through noticing and self-explanation.

Intercultural competence is a skill of growing importance, but it is difficult for students to acquire. A typical learning task in this domain is participation in discussion, but as many classes move online, students do not always get the discussion support available in a traditional classroom. We develop a simple model for good cultural discussion and use it to explore a method of assessing student contributions to an online forum and delivering feedback–a peer moderator from the class supported by adaptive assistance.

While intelligent tutoring systems have been successful at promoting learning, students may fail to benefit if they are not motivated or engaged. We added game elements to an intelligent tutoring system for teaching the distinctions between French past tense forms, creating a narrative game in which players edit articles in a virtual journalism office. In a study with 38 students, we compared the game version to a non-game version of the system and assessed motivational responses.

We visited three Latin American countries and observed use of the Middle School Mathematics Tutor in a school in each country.

Games are increasingly being used as educational tools, in part because they are presumed to enhance student motivation. We look at student motivation in games from the viewpoint of attribution theory, which predicts more learning by students who make attributions along certain dimensions, and thus may provide a way of examining this claim in more detail. We studied 13 students as they played a game designed to teach negotiation skills in a cultural context.

When considering instruction in interpersonal domains, such as intercultural negotiation, the development of an interpersonal relationship with one's pedagogical agent may play a significant role in learning. However, there is conflicting evidence in the literature both regarding the ability of agents to cultivate social relationships with humans, and their effect on learning.

Educational games may be particularly suited to teaching social learning skills with virtual humans. We investigate the importance of social goals and engaging social interactions in learning from such games. In one experiment, students played a cultural negotiation game with an explicit social goal or only negotiation task goals. While the group without the explicit social goal learned significantly more, students who reported having social goals in a manipulation check learned the most.
