Can we better understand the technology in engineering education with virtual 3D models?

  • This study examines the effects of using different types of visualization for task in- structions within engineering studies. Participant observation and guided group interviews were used to determine both the learning difficulties of students and their expectations towards the educational use of 3D models.Comparing between three different modes of representation of the same model (2D drawings, per-spective 3D models and stereoscopicobject representations), the performance of task execution, the speed for task handling and the perceived cognitive workload of one taskwere measured. 183 students take part in the study. It was found, that the participants that used stereoscopic object-representations per-ceived task less complex than the groups using perspective 3D or paper based 2D-representations.
