• Part visualization, which refers to read and understand any technical drawing, is a fundamental skill in engineering. However, engineering students show certain learning difficulties and a high failure rate in subjects such as Engineering Graphics. The main aim of this study is to introduce a new teaching strategy for part visualization. A problem-solving model for visualization has first to be designed. Teaching strategies may then be applied, by drawing up a programme of specific tasks which takes into account the theoretical contents and procedures involved in part visualization and students' main difficulties and deficiencies when solving this kind of problem. After testing the method in the classroom, the results which were obtained from test and control groups were contrasted, showing an important improvement.
