Hans-Stefan Siller

Prof. Dr. Hans-Stefan Siller is Chair of Mathematics V (Mathematics Education) at the Institute of Mathematics, University of Würzburg. He has held this position since 2017, after serving as Professor of Mathematics Education at the University of Koblenz-Landau (2012-2017). His office is located in Building 30 (Mathematics West), Room 01.010, at Emil-Fischer-Straße 30 in Würzburg, with contact information including phone +49 931 31-89867 and email hans-stefan.siller@mathematik.uni-wuerzburg.de.

Prof. Siller's research centers on mathematical modeling and its connections to reality, digital tools and media in mathematics education, assessment methodologies, teaching-learning laboratories (microteaching), and STEM perspectives in mathematics. His work emphasizes practical applications of mathematical concepts in educational settings, particularly through the development of effective teaching strategies and resources. His educational background includes a Dr. rer. nat. from Paris-Lodron-Universität Salzburg (2006) and habilitation at the University of Vienna (2012), with prior experience as a high school teacher for mathematics, physics, and computer science in Salzburg.

His recent publications reveal a strong focus on mathematical modeling competence in teacher education contexts, with increasing attention to how teachers develop adaptive intervention skills during mathematical modeling processes. There's a clear trend toward examining digital tools integration in mathematics instruction and exploring fundamental mental models for calculus concepts. His research also investigates historical dimensions of mathematics education and practical classroom applications for teacher training.

Prof. Siller leads the Mathematics Education department at the University of Würzburg, where he oversees the "LEED-Lehr-Lern-Labore" project focused on enactive, experimental, and digital learning environments. He serves as editor for journals including "Der Mathematikunterricht" and "Praxis der Mathematik in der Schule," and has co-edited multiple books through the ISTRON group. He maintains strong connections with schools through various projects that bridge university research and classroom practice, particularly in developing frameworks for evaluating teacher competence in mathematical modeling instruction.
