This paper presents a novel theory-based teaching concept for bachelor students on the subject of 'digitalization'. The constant increase of changes driven by the surrounding context of digitalization affects all areas of industry and social life. Consequently, there is an urgent need to anchor the topic of digitalization in a holistic approach in engineering education. This paper contributes to the research discourse on suitable implementation methods in the teaching-learning module 'Summer School Technology 4.0: Digitalization'. The contribution aims to generate new insights for engineering education practice and research (1) by classifying the significance of 'digitalization' in the research landscape of engineering didactics, (2) by demonstrating the diversity-oriented and student-centered theoretical study approach of the teaching-learning concept and the embedding in the research of teaching-learning, (3) through the presentation of the methodological-didactic design of the course and its implementation in engineering education, and (4) by the introduction of the evaluation concept in mixed method design.
