Revitalizing the way we assess, is essential for the quality of interdisciplinary education within academia. Society today asks for a new generation of academics who can direct and reflect on their own learning process and development. It asks for assessment designs that continuously drives student learning. This workshop gives you - as university teacher - a kick-start when you want to change your assessment practice by presenting building blocks for meaningful assessment: assessment with the right purpose in mind, powerful feedback, alignment with pedagogical beliefs, alignment with learning outcomes and authentic assessment tasks. Furthermore, we demonstrate inspiring assessment practices that cover some of the most important skills that foster interdisciplinary understanding such as integration, collaboration, critical thinking and reflection. In the second part of this workshop, we will discuss opportunities to assess these skills in your own teaching practice. We will specifically focus on how to make your assessment practice more authentic, how to provide your students with powerful feedback and how to let students take the lead in their own learning process. This workshop will serve as a foothold to empower students to be independent self-assessors not just during their academic education but as long-life learners.
