Sonalysts' Closed-Loop Adaptive Training (CLAT) is an emerging concept that integrates object/objective-based adaptive interactive multimedia instruction (IMI) and simulation-based intelligent tutoring with a robust learner model. The result is an inherently learner-focused approach that manages mastery of knowledge and skill learning objectives dynamically. Students can learn new concepts, practice associated skills and be assessed on their mastery of the requisite knowledge and skills, all under the guidance of a synthetic tutor.
