The ECOSSE Control HyperCourse is a course in process control availabl
e on the World Wide Web. It is used by undergraduates as a supplement
to lectures, tutorials and experiments. It is also intended as a refre
sher or extension course for process engineers in industry. In this pa
per we describe some features of this novel approach to control teachi
ng. In particular we show how the teaching material is presented in a
variety of ways from simple lecture notes through to interactive simul
ations of laboratory control experiments.
