First results of the iterative STEAM design process in 3D modelling and printing with pre-service teachers

While we examined mathematical modelling of architectures with CAD software during the last years, we intended in our higher education courses in pre-service elementary school teachers' initial training to expand the complexity of the modelling tasks. In addition, our previous research results indicated a high difference between the quality and functionality of designs by students. Therefore, we investigated the design process in 3D modelling and printing. Based on the industrial iterative design process (e.g., design of a pen), we became aware of the importance of iterative process milestones, quality controls, discussions and peer evaluations. Therefore, we created a remote teaching course for pre-service teachers to design complex objects (e.g., functionality) and create learning settings and tasks based on an iterative design process concept. We will present the first results and reflections at this conference.
