Dr. Niels Seidel, Senior Researcher at CATALPA

At the CATALPA research center, we conduct highly data-driven research at the intersection of higher education, educational technology, and artificial intelligence. In this presentation, I would like to share experiences from several interdisciplinary research projects, focusing on the practical methods, processes, and tools for handling research data that drive our work forward. Following Marie Kondo's example, this year's focus is on discarding and tidying up research data.
