Subclaims¶

q2 i? In the authors' own data, four seemingly different wrong answers to a loop-output prediction task reduce to three distinct mental models plus one combination of two of them, showing the taxonomy's definitional clarity aids error categorization. → Dimitri Eckert and Christian Kautz 2026

Dimitri Eckert and Christian Kautz. (2026). How Students (Mis)understand Conditionals and Loops – A Taxonomy. arXiv preprint. https://arxiv.org/abs/2605.26966 doi:10.48550/arxiv.2605.26966

q2 · i? · design · r2

In the usage example, students predicted the output of a given loop program; common wrong answers were traced to the misconception Iteration-(3)-(b)-(ii)-(A) (update before body) alone or combined with Iteration-(3)-(a)-(ii). The authors conclude "four seemingly different errors actually consist of three mental models".

"Here four seemingly different errors actually consist of three mental models and one combination of two of them."
