Sixty-two students participated in the study and were either in their first year to learn about computer science or were more experienced computer science students. In terms of learning performance, only the first-year students benefited from our guided DBL approach. In contrast, the experienced students were highly motivated to learn computer science not only immediately after the intervention, but also in the long term. For first-year students, this effect was only evident directly after the intervention. Overall, the guided DBL design proved to be effective for both motivation and learning, especially for younger students. For older learners, a better balance between guidance and autonomy is recommended. 4950 https://doi.org/10.3390/mti5080041$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:hbz:465-20220519-150952-6$xR$3Volltext$534 4961 https://duepublico2.uni-due.de/receive/duepublico_mods_00074723 5051 370 5550 augmented reality 5550 computer science education 5550 design-based learning 5550 learner-generated content 5550 motivation
