Objectives To develop a general concept for flexible computer-based instructions for distance learning in the field of Control Engineering - To develop a multimedia based instruction in 'Simulation and Experimental Modelling' Description A CD-ROM based interactive multimedia instruction in 'Simulation and Experimental Modelling' is developed. It consists of hyper media material with questions and examples. The authoring program Medi8or is used. Part of the content is based on a new sensitivity approach for direct estimation of physical parameters. The presentation is inspired by Solomans inventory of learning styles. To enhance active learning and motivation of real life problems, use of the simulation tool Matlab is integrated in the instruction. The project stems from a demand for upgrading Danish Engineering School teachers in advanced control engineering, and the course id developed in cooperation with a group of these teachers.
