Abstract
Within the CoLoS project a new method has been implemented to overcome the obstacle of complex interfaces, which all too frequently form a barrier between the content to be studied and the support, expected to be presented by the computer.
The new method is based on the ICCCM mechanism. It permits control of the simulation through active links within an html-document. It allows any teacher or author to decide the level of interaction accessible to the learner and to define the most appropriate balance between freedom to explore and guidance provided by the software.
The applied mechanism supports distributed use of teaching material from a central depository over the Internet.
