In January 2011, the US Army Training and Doctrine Command (TRADOC) published the "Army Learning Concept for 2015 (ALC 2015),"  describing sweeping changes in the way Soldiers will be trained in the future. Noting that digital age learners are comfortable with technology, ALC 2015, now known as the Army Learning Model (ALM), describes how current and future technology can be leveraged to "make learning content more operationally relevant, engaging, individually tailored, and accessible." The concept moves away from instructor-led training using hundreds of presentation slides to 1) small group, collaborative problem-solving environments; 2) learning tailored to the individual's experience level; and, 3) a blended learning environment, using live, virtual, and constructive simulations and games. The Army Research Lab's Simulation and Training Technology Center and the Army Research Institute are conducting research into the development of advanced technology-enabled training methodologies. They are developing an integrated learning environment and prototype instructional materials, and assessing their effectiveness as tools to develop, deliver, and track training and education. Consistent with ALC 2015 concepts, the Soldier-Centered Army Learning Environment (SCALE) provides a prototype data-driven architecture to support training and education across multiple hardware platforms (personal computer and mobile devices), using mobile applications, virtual classrooms, and virtual worlds. This paper provides an overview of the initial SCALE prototype and a sample training application, based on land navigation. In addition, we will discuss our preliminary results of using data-driven concepts in a learning environment, including the use of an ontology engine to organize training content and the methods used to provide this training content and data to client applications.
