Tools to Support the Design, Execution and Visualization of Instructional Designs

Describing CSCL scenarios can be performed in a standard way. To do so, Instructional Design or so called Learning Design (LD) can be used for describing CSCL scenarios by mean of a de facto specification known as IMS Learning Design (IMS-LD). A typical teaching/learning scenario based on this specification implies the use of several tools which must interact all together. This paper will show a set of tools that enriches the learning scenarios based on IMS-LD. The tools we are developing allow graphical editing of instructional design, a generic engine and a customizable player.
