From 3 to 7 March 2025, Ayline Heursen presented the team’s work at the 58th Annual Conference of the Gesellschaft für Didaktik der Mathematik (GDM) in Saarbrücken, marking the society’s 50th anniversary. The presentation, “Entwicklung von Eye-Tracking Vignetten zu systematischen Fehlern bei der Interpretation statistischer Graphen” (“Developing Eye-Tracking Vignettes on Systematic Errors in Interpreting Statistical Graphs”), was co-authored with Markus Vogel, Saskia Schreiter, Frank Reinhold, Martin Abt, Lonneke Boels, Vuslat Şeker, and Wim Van Dooren.

The talk introduced how the project’s eye-tracking vignettes are designed to help mathematics teachers recognise systematic errors in students’ interpretation of dotplots, histograms, boxplots, and case-value plots, and sparked discussion with the wider German-speaking mathematics education research community gathered in Saarbrücken.
