Sottilare1, Arthur C. Graesser2, Xiangen Hu2, and Heather Holden1, Eds. U.S. Army Research Laboratory - Human Research and Engineering Directorate1 University of Memphis Institute for Intelligent Systems2 i Design Recommendations for Intelligent Tutoring Systems - Volume 1: Learner Modeling This book is the first in a planned series of books that examine key topics (e.g., learner modeling, instructional strategies, authoring, domain modeling, learning effect, and team tutoring) in intelligent tutoring system (ITS) design through the lens of the Generalized Intelligent Framework for Tutoring (GIFT; Sottilare, Brawner, Goldberg, and Holden, 2012), a modular, service-oriented architecture created to develop standards for authoring, managing instruction, and analyzing the effect of ITS technologies. This preface introduces tutoring functions, provides learner modeling examples, and examines the motivation for standards for the design, authoring, instruction, and analysis functions within ITSs. Next, we introduce GIFT design principles, and finally, we discuss how readers might use this book as a design tool. We begin by examining the concept of learner modeling. Learner modeling (also known as student modeling or user modeling) is one of the major components of ITS. Learner modeling is a key to the computer-based tutor’s understanding of the learner. Comprehensive, real-time modeling of the learner is a critical element in the design and development of truly adaptive tutoring systems that can tailor tutoring experiences to the needs of the individual learner and teams of learners. It is generally accepted that an ITS has four major components (Elson-Cook, 1993; Nkambou, Mizoguchi & Bourdeau, 2010; Graesser, Conley & Olney, 2012; Psotka & Mutter, 2008; Sleeman & Brown, 1982; VanLehn, 2006; Woolf, 2009): The domain model, the student model, the tutoring model, and the user- interface model. GIFT similarly adopts this four-part distinction, but with slightly different corresponding labels (domain module, learner module, pedagogical module, and tutor-user interface) and the addition of the sensor module, which can be viewed as an expansion of the user interface. (1) The domain model contains the set of skills, knowledge, and strategies of the topic being tutored. It normally contains the ideal expert knowledge and also the bugs, mal-rules, and misconceptions that students periodically exhibit. (2) The learner model consists of the cognitive,
