Editor's Notes

  1. Learning Object Context as is a kind of LO metadata (we also call it context-awareness metadata) that captures all the information that characterizes the specific situations (contexts) in which certain LO has been used. A (specific) learning situation is determined by the learning activity, the learning content, and the learner(s) involved. Aimed at capturing diverse kinds of learning situations typical for modern e-Learning environments In a nutshell, context, as defined here, is about a student (or a group of students) interacting with a learning content by performing certain activity with a particular purpose in mind.

  3. implemented as an extension of the well-known open-source Reload Content Packaging Editor this design decision ensured that instructors effectively use the same tool for creating LOs, receiving and viewing automatically generated feedback about their use, and modifying the LOs accordingly. The main goal was to enable easier and wider acceptance of LOCO-Analyst.
