This paper describes what is meant by modelling at Sunderland and how System Dynamics fits into this ethos. The teaching and the examples covered in this System dynamics module are different the usual course and the paper deals with our experience in these areas. The reaction of Eastern European ( Bulgarian ) students to this type of teaching is discussed. Students must complete a project in a work placement to obtain a masters qualification. The reaction of companies to the use of System Dynamics ( a new experience for most ) is discussed and examples of the type of projects that have been completed are given. The paper concludes with a description of a Hypercard project which extends the use of System dynamics to Engineering students.
