With the increasing complexity of software systems, it is becoming more and more relevant for students in software engineering education to learn how to elicitate requirements from customers or stakeholders and visualize them in a diagram. This continues to present different challenges to novice modellers. To counteract these, educators and researchers have developed support tools. These offer various functionalities to address different challenges. However, it is unclear what functionality needs to be provided to address all of these issues and not just individual ones. Therefore, this paper extracts such functional requirements and summarizes them. It also shows how they can be translated into activities during an exercise lesson.
