Courses that exceed regular class sizes represent a challenge for teachers. With an increasing number of students, it is not only difficult to assess students’ academic performance but also their social integration. A teacher who is not able to determine which students are isolated may not be able to intervene if they choose to cut their studies short. In this research paper we demonstrate how teachers are able to assess their students’ social integration by leaving it up to the students to self-select their group work partners and solve tasks together. The introduction of a newly created artifact helps to automate this process and gather the necessary data to discover companionless students even in larger learning environments.
