Intelligent Tutoring Systems (ITS) review actions taken by the user and provide dynamic feedback to teach subject matter to an individual. ITSs have proven successful at teaching math, physics, and programming.  An Intelligent Team Tutoring System (ITTS) assesses the performance of a team's individuals, their overall performance as a team, and the interactions of that team to provide dynamic feedback. While extensive research has been conducted regarding single person ITSs, work regarding ITTSs is limited.  An ITTS is difficult to design, as the tutor must account for the actions of multiple individuals and their team interactions. The tutor must teach task skills for completing the objective, and team skills for how a team works together to meet the objective. This talk will describe three of the first ITTSs created: a 2-person surveillance task, a 3-person surveillance task, and a 3-person shopping task, each implemented in an virtual environment. The talk will describe the system architecture required to support team tutoring, some of the metrics for team performance, and the triggers for team and individual feedback.
