Prof. Dr. Andreas Obersteiner


Mathematics Education

Academic Career and Research Areas

Prof. Obersteiner’s research focusses on understanding and supporting mathematical thinking and learning processes. His research is interdisciplinary and aims at connecting basic cognitive research with educational practice. To that end, he uses a variety of research methods, including traditional methods as well as measures of reaction times and eye movements.

Prof. Obersteiner studied mathematics and physical education at the University of Regensburg. After his state examinations for secondary school teaching, he completed his PhD and Habilitation in mathematics education. Two research stays, in Belgium and the United States, were supported by research foundations, including the Alexander von Humboldt-Foundation. In 2016, Prof. Obersteiner was appointed professor at the University of Education in Freiburg. Since 2021, he has been holding the Heinz Nixdorf-Chair for Mathematics Education at the TUM School of Social Sciences and Technology, Department Educational Sciences (former TUM School of Education).
