Recently, hybrid classroom-ITS approaches have arisen, creating
blended classrooms and distance learning environments in
which instruction and example problems are shown in online
videos, PowerPoint presentations, and online ITS [22]. While
new monikers, including “e-Learning 2.0,” “Adaptive Educational
Hypermedia Systems,” and “Learning Management
Systems” have arisen to describe the current state of the art in
online classroom environments, such systems are still in the
experimental stage, offering limited capabilities for content
authoring and course administration [26].
