Research interests and projects.
The central question is how digital mathematics textbooks should be designed to be interactive, effective, and accessible to all learners. In my dissertation, I empirically investigated the effectiveness of a digital textbook compared to printed materials in the field of conditional probability. As part of the DEM project, I was also involved in developing guidelines for the design and development of digital textbooks.
How do students use digital teaching and learning materials with integrated tools or AI features? What potentials and challenges arise from their use?
Construction of test instruments for empirical research, evaluation of items for the VERA-8 comparative tests, and design of accessible digital assessment formats.
An empirical study on the effectiveness of the digital textbook in the field of conditional probability (original title: „Digitales versus analoges Schulbuch“).
Doctorate (Dr. phil.) in mathematics education, Faculty 10 – Mathematics and Computer Science, University of Münster.
