It focuses on approval processes and criteria set by the 16 federal states, arguing that these have the potential to influence the development of DCR. Using qualitative content analysis, the study explores three research questions: which DCR require official approval, the criteria applied for approval, and the extent to which these criteria are mathematics-specific. Findings indicate that 10 federal states maintain official approval systems, covering digital equivalents of printed textbooks and selected supplemental materials. However, most DCR fall outside these regulated processes, leaving their evaluation largely to individual schools and teachers. The study identifies 17 categories of quality criteria, but reveals a lack of detailed, mathematics-specific requirements. Instead, many criteria are broad references to didactical principles and educational goals, leaving the interpretation and application of these quality standards open-ended. Subject-specific criteria are included but remain limited in specificity. The study underscores the need for research-informed, mathematics-specific quality standards to guide DCR development and approval, emphasizing their importance amidst challenges like artificial intelligence. Policymakers are urged to adopt clearer criteria to ensure high-quality DCR to be used in schools.}}, author = {{Rezat, Sebastian}}, issn = {{1863-9690}}, journal = {{ZDM – Mathematics Education}}, keywords = {{governance, digital curriculum resources, digital textbooks, digital curriculum materials, quality}}, pages = {{ 891–904}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{The quality of digital curriculum resources for mathematics in German educational policy}}}, doi = {{10.1007/s11858-025-01708-w}}, volume = {{57}}, year = {{2025}}, } @article{52584, author = {{Rezat, Sebastian}}, journal = {{ZDM – Mathematics Education}}, publisher = {{Springer}}, title = {{{Research on curriculum resources in mathematics education: a survey of the field}}}, doi = {{10.1007/s11858-024-01559-x}}, year = {{2024}}, } @inproceedings{55191, author = {{Rezat, Sebastian and Visnovska, Jana and Yan, Guorui and Leshota, Moneoang and Sabra, Hussein}}, booktitle = {{Proceedings of the 14th International Congress on Mathematical Education}}, keywords = {{Mathematics, Mathematik, Textbook, Curriculum Resources, Schulbuch}}, pages = {{537–545}}, publisher = {{World Scientific}}, title = {{{Topic Study Group 41: Research and development on textbooks and resources for learning and teaching mathematics}}}, doi = {{10.1142/9789811287152_0065}}, volume = {{1}}, year = {{2024}}, } @inbook{57390, author = {{Rezat, Sebastian and Westbury, Ian}}, booktitle = {{Fourth International Handbook of Mathematics Education}}, editor = {{Clements, M.A. (Ken) and Kaur, Berinderjeet and Lowrie, Thomas and Mesa, Vilma and Prytz, Johan}}, isbn = {{9783031514739}}, issn = {{2197-1951}}, publisher = {{Springer Nature Switzerland}}, title = {{{Textbooks and curriculum from a governance perspective}}}, doi = {{10.1007/978-3-031-51474-6_24}}, year = {{2024}}, } @inproceedings{57613, author = {{Rezat, Sebastian}}, booktitle = {{Proceedings of FAME 1 – Feedback & Assessment in Mathematics Education (ETC 14), 5-7 June 2024, Utrecht (The Netherlands)}}, editor = {{Iannone, Paola and Moons, Filip and Drüke-Noe, Christina and Geraniou, Eirini and Morselli, Francesca and Klingbeil, Katrin and Veldhuis, Michiel and Olsher, Shai}}, pages = {{262–269}}, publisher = {{Utrecht University and ERME}}, title = {{{Students' instrumentalizations of hints and automated feedback in their task solution process when learning mathematics with a digital curriculum resource}}}, doi = {{10.5281/zenodo.14231455}}, year = {{2024}}, } @inproceedings{58851, author = {{Stallmeister, Lea and Rezat, Sebastian}}, booktitle = {{Beiträge zum Mathematikunterricht 2024 - 57.
