Versioning electronic learning objects

摘要

An electronic learning system includes a master repository which stores existing versions of learning objects, a local repository which stores alternate versions of the learning objects stored in the master repository, and a processor that executes instructions to display content that is based on at least some of the alternate versions of the learning objects and at least some of the existing versions of the learning objects. The processor detects a conflict associated with an alternate version of a learning object stored in the local repository, and resolves the conflict.
