One of today’s central challenges is the digital transformation of the workplace, as the rapid development of digital technologies is leading to changes in professions. Consequently, innovative educational concepts are needed to prepare students for the required competence profile and to ensure that they can enter the workplace with a digital-technological basic education. The Danish-German DiASper project (Digital Working World from School Perspective) therefore aims to implement aspects of digital technologies of the digital workplace in regular STEM school lessons. Taking the digital and technological processes of 3D printing as the starting point, the project has identified learning contents that address both the curricular contents of mathematics and the digital technologies of the workplace. Technological processes of 3D printing, namely modeling, triangulation, slicing and printing, can be used as a learning context to teach mathematical content in both geometry and calculus. For instance, the use of a CAD-software enables students of different grades to analyze composite figures by spinning the object virtually, thus providing the possibility to enhance students’ spatial visualization ability. The project follows the design-based research approach to adapt the teaching concepts for the possibility of an optimized use in mathematics teaching. This paper gives an insight into the conceptual framework of the DiASper project as well as the project goals.
