Making Lab Sessions Mandatory -- On Student Work Distribution in a Gamified Project Course on Market-Driven Software Engineering

Unfair work distribution in student teams is a common issue in project-based learning. One contributing factor is that students are differently skilled developers. In a course with group work intertwining engineering and business aspects, we designed an intervention to help novice programmers, i.e., we introduced mandatory programming lab sessions. However, the intervention did not affect the work distribution, showing that more is needed to balance the workload. Contrary to our goal, the intervention was very well received among experienced students, but unpopular with students weak at programming.
