Tomma Jetses

Tomma Jetses is a Researcher at the Institute for Mathematics Education within the Faculty of Mathematics at Bielefeld University, where they have been working since April 2024. Prior to this, Jetses served as a research associate at the Mathematics Didactics Group at the University of Osnabrück since 2018. Their academic background includes a Master of Education (Gym/Ges) in Mathematics and French from the University of Osnabrück (2015-2018) and a Bachelor of Arts in the same subjects (2012-2015).

Jetses' research focuses on mathematics education with particular emphasis on conceptual understanding of mathematical concepts, function concepts, derivation/calculus concepts, and the cognitive processes involved in learning mathematics. Their work often employs qualitative methodologies including interview studies to investigate how students develop mathematical understanding, especially during critical transitions such as from school to university mathematics.

Analysis of Jetses' publication record from 2019-2024 reveals a consistent focus on basic representation theory in mathematics education, with particular attention to conceptual difficulties students face with fundamental mathematical concepts like functions and derivatives. Their research often examines the transition challenges between school and university mathematics, identifying specific misconceptions and developing theoretical frameworks for understanding mathematical concept development.

Jetses frequently collaborates with Alexander Salle and other researchers in the mathematics education field, with multiple co-authored publications appearing in prominent German mathematics education journals and conference proceedings. Their work bridges theoretical frameworks like APOS theory with practical classroom applications, particularly in developing digital and enactive learning approaches for complex mathematical concepts.
