Gerald Wittmann

Gerald Wittmann is a Professor of Mathematics and Mathematics Didactics at the University of Education Freiburg since 2010. He previously held the same position at the University of Education Schwäbisch Gmünd until 2010.

His research focuses on mathematics education, particularly conceptual and procedural knowledge in fraction learning, language-sensitive teaching, and textbook analysis. Recent work explores individual differences in mathematical cognition and adaptive teaching strategies.

The 15 most recent publications analyze fraction knowledge, textbook design, language-responsive learning, and contextual mathematics instruction. Key trends include empirical assessments of procedural and conceptual understanding and the role of visualizations in pedagogy.

Projects include roles as deputy leader in initiatives like HELPS and VISDEM II, funded by institutions such as the German Center for Mathematics Teacher Education (DZLM) and the Federal Ministry of Education and Research (BMBF).
