Challenges for Students of Mechanical Engineering Using UML - Typical Questions and Faults

The digitalization of teaching due to the Covid-19 pandemic offers new challenges, yet also new opportunities. To assist and encourage students in their self-study of the unified modeling language (UML), modeling tasks were provided; then student solutions were analyzed and discussed in web meetings. This way, earlier and more in-depth insights into typical faults in the students' modeling solutions could be achieved. Two groups of students were considered, and it was examined whether students make fewer or different faults in modeling depending on their maturity and pre-knowledge.
