Project-based learning in higher education becomes more relevant and job-field-related if it is done in real, or at least realistic, project settings, e.g. including specific team situations or case studies from companies. Such projects are specifically valuable if they are conducted by internationally mixed student teams, best case in interdisciplinary teams. Online participation can be both more realistic and helpful in case physical mobility is not possible. Therefore, we are conducting virtual projects with cross-border student teams. Selecting the right projects and matching the right students with the relevant company cases is very important for an effective and efficient competence delivery. The project selection based on the desired competence gain, the development of a meaningful sequence of projects in order to implement an individual competence development path, the estimation of the contribution of the projects to the desired competence profile of the student, and the implementation of the projects need to be supported by digital tools and a virtual environment. This allows access to projects and company cases from different countries and an international, cross-border learning experience -best case in realistic interdisciplinary teams. This paper describes the concepts and tools for this approach and their experimental analysis.
