Distributed Learning Interoperability with Embedded Training and Intelligent Tutors

Training benefits have been widely documented for Intelligent Tutoring System (ITS) approaches integrated with virtual trainers, especially for embedded settings where human instructors are less available. Yet these forms of training are generally not available in distributed learning curricula with models such as SCORM (Sharable Content Object Reference Model), due to the limitations of browser based delivery methods. However, emerging concepts in the distributed learning community provide mechanisms that can be used to construct interoperability with such trainers. Notionally, a SCORM course could incorporate training events on a variety of available platforms, such as an embedded training system or an immersive virtual system at a training facility, which can exercise equivalent learning objectives. This paper describes findings from a prototype effort for the Joint Advanced Distributed Learning Co-Lab, to construct a mechanism for SCORM interoperability with an existing embedded training testbed, the Command and Control Vehicle (C2V) ITS at Army RDECOM. The C2V testbed exercises unmanned vehicle control concepts and skills, in a physical configuration mirroring the embedded training setting onboard an actual C2V. As a standalone trainer, this testbed cannot be integrated with a browser based learning environment in the traditional manner. Therefore the interoperable architecture includes a mechanism to configure and launch training events based on the instructional sequencing inputs from a SCORM course, while aiming to provide
