Realizing a complex student project over several semesters

Project Based Learning (PBL) has become a popular method for lab courses to teach practical topics. Most of the student projects are tailored in their complexity and need a defined time for a student team within one semester. With this defined and often reduced complexity of the projects the practical relevance is doubtful. In this here shown approach for a PBL lab an industry project with the original complexity is used and structured into several parts. These are sequentially dependent and have to be solved in a defined order by student groups. Each group has to develop one component and has the responsibility for a working result at the end of their subproject. Each group interacts with other groups during the same semester to develop a working system. Student groups in the following semesters take the results from previous semesters and develop the entire project further on. With this type of PBL an own dynamic of the student work is evolving which is not possible with small complexity tailored projects.
