What You Check is What You Get: Authoring with jEditOQMath

jEditOQMath is an authoring tool for the intelligent learning environment Active Math. Its editing interface is a simple source editor. However the wealth and power of the authoring tool lies elsewhere, namely in its integration into the learning platform, so that authors design a great learning experience and not simply a great content editing view. In this paper, we describe the tool and propose to name its paradigm WYCIWYG: What you Check is What You Get. The instrumental approach of human computer interaction is applied to analyze the practice and to explain how the edited source becomes the instrument to communicate with the learning environment.
