In engineering design education several studies had been made to understand the differences between how novice and experienced designers approach design tasks. As a central finding it is described that novice designers tend to use a particular pattern of trial and error whereas experienced designers use particular design strategies. One essential part of these design strategies are visual analysing strategies. The identification of such strategies is a challenging research task and conventional research methods like interviews, document analysis and protocol studies are currently reaching their limits regarding the accurateness and validity of measuring data. At this point eye tracking analysis provides the opportunity to decisively improve the research of expertsâ strategies and thus allows a more sophisticated support of novice designer in engineering design education. This paper presents first results of eye tracking experiments that are presently conducted with novice and experienced mechanical engineers to gain additional insights in their visual strategies when analysing design representations (e.g. technical drawings). Based on the results it finally is discussed how identified visual strategies can be trained in design education in order to support the studentsâ understanding of design representations.
