Tanja Dackermann

Dr. Tanja Dackermann is a Researcher at the Leibniz Institute for Science and Mathematics Education (IWM) in Tübingen, Germany, where she has served as a research assistant since August 2014 and was a member of the former Junior Research Group Neuro-cognitive Plasticity.

Her educational foundation includes a Diploma in Psychology from Justus Liebig University Gießen and the University of Tübingen. From 2011 to 2014, she completed her doctoral studies as a scholarship holder of the Cooperative Research Training Group funded by the Ministry of Science, Research and the Arts in Baden-Württemberg, investigating spatial representations of number magnitude and embodied numerical training approaches.

Dr. Dackermann's research centers on numerical cognition with emphasis on developmental trajectories of numerical skills in children. She pioneers embodied and media-supported training programs to enhance basic numerical competencies while developing diagnostic tools for identifying mathematical learning difficulties. Her work bridges cognitive psychology with practical educational applications, demonstrating how physical interaction and digital media transform mathematical learning processes through rigorous empirical investigation.

Analysis of her publication record reveals consistent innovation in number line estimation methodologies, exploring bounded versus unbounded task constraints, multimodal presentation formats, and embodied training effects across diverse learner populations. This research program demonstrates how spatial-numerical associations predict arithmetic development and informs targeted interventions for children with mathematical learning difficulties.

At the IWM, Dr. Dackermann contributes to the institute's research ecosystem through engagement with labs focused on multimodal interaction and knowledge construction, advancing the institute's mission to optimize digital learning environments through evidence-based cognitive science research.
