MASS. Marburg university auto ASess System

In computer science, in particular in early program-ming courses, students often do not fully solve an assignment on their first try. While teachers and tutors can provide individual feedback in such cases, they are only available to a limit. Auto-matic feedback tools can be available 24/7 but are limited in how individual their feedback is. The MASS system is an automatic feedback tool that can flexibly be configured by teachers on a per-assignment basis to provide individual feedback tailored to their courses and the current learning stage of students.
