| The ClassSync Modeling Language (CML) addresses the problem of creating a controlling overlay to classroom learning activities, or e-leaming workflows. Our aim is to allow authors and teachers to generate a mapping from activity design to its implementation in a wirelessly networked classroom with ubiquitous use of handheld computers for information exchange. CML models e-learning workflows with three major components: actors, data objects, and interaction networks. Actors are the diverse perfonners of actions. data objects are the semantically typed information units that are made available for exchange. Interaction networks are virtual networks constructed on top of whatever network ClassSync is running on. and dictate how information may flow through the ClassSync system (from actor to actor). Activities are the processes performed via these three components, in which actors create and consume data objects and exchange them over an interaction network. The benefits of this approach for students, curriculum designers, teachers, publishers and learning sciences researchers are highlighted. |
