3D modelling; STEAM; education

3D printers appear at all types of schools more and more frequently. To exploit them effectively, educators must become familiar with their appropriate application in courses. The authors participate in an international ERASMUS+ project that intends to assist future (pre-service) teachers in planning and carrying out their future teaching activities with 3D modelling through a STEAM-based transdisciplinary approach. The main aim of our project is to design, develop, and implement appropriate teaching and learning practices using 3D modelling. In order to follow contemporary trends in education, we prefer and promote the learning-tolearn approach based on "learning to do" tasks. They address 3D modelling in order to enhance learners' creativity. To enhance our students' motivation, we invite them to design and develop subjects for their needs. A MOOC is a part of the project to support both teacher training and school-based STEAM learning. It aims to facilitate instant and worldwide access to STEAM learning. In particular, we pay attention to and respect the specifics of partner countries' curricula and teacher training. The tasks and activities address both in-class and online courses for future teachers. Our paper contains selected examples. As our long-term aim is to concentrate on transdisciplinary education, we develop not only these activities. Moreover, we create a repository of high-quality teaching and learning resources as well as their evaluation criteria. The dissemination of project results is also premeditated.
