In January 2022 the Faculty of Technical Sciences (TECH) at Aarhus University (AU) appointed a working group to develop a didactic foundation for teaching at TECH. The background was a need to develop a joint platform for teaching, pedagogical competence development, and other educational activities at the faculty, after a recent history of organizational mergers and changes, and subsequent development of a new joint strategy. The working group was to identify important factors that should characterize future teaching at TECH and propose a commonly recommended foundation upon which TECH teachers can collectively build, reflect, and improve their teaching. This paper will justify and describe the work process, present and reflect upon the outcome, relate the outcome to the CDIO Standards and Syllabus, discuss lessons learnt, and provide advice for others engaging in similar work.
