This practice paper describes the implementation of a problem- based learning approach that deals with the multifaceted problems of the textile industry. Therefore, an interdisciplinary module was implemented that deals with the topics of the textile value chain, sustainability and production simulation. The students develop solutions to increase sustainability in the textile industry and use simulation software to test their ideas. To ensure successful student outcomes and to respond to the individual programming questions of the students, constructive feedback and dialogue were key elements of the seminar. The seminar is developed using the design-based research approach. Within the scope of this paper, the first implementation of the designed learning approach is described and reviewed based on student and teacher feedback.
