We pursue an evidence-based, integrated research approach with a focus on international exchange. We believe that the quality of educational processes and policies needs to be validated empirically. In all our studies, we utilize the most reliable and valid statistical methods in educational research and regularly present our findings to the international community at conferences and in journals leading the fields of education and psychology. Furthermore, we aim to expand our engagement in the international research community through collaboration and partnership using an interdisciplinary approach. Therefore, we collaborate with researchers and colleagues from the fields of psychology and educational sciences as well as mathematics, linguistics, statistics, economics and sports sciences.
