This study examines the role of\r\nproblem-solving heuristics among 73 sixth-grade students in a German secondary\r\nschool (Gesamtschule). Specifically, we focus on the empirical relationship between\r\nthe occurrence of heuristics, their suitability, and application, as well as their contribution\r\nto problem-solving success. To this end, we developed a heuristic training that\r\nintroduced strategy keys (heuristic aid cards) accompanied by explanatory videos. By\r\nleveraging variations in the successful application of the heuristics between students\r\nand across multiple sessions (73 students in 4 training situations and 3 problems\r\nin a final test), we discover from regression models with student and task-fixed effects\r\nthat a successful use of heuristics (i.e., an heuristic occurred, that heuristic had\r\na high suitability regarding the problem, and it was applied correctly) leads to more\r\nsuccessful mathematical problem solving. Regarding the underlying mechanism, we\r\nfind that all dimensions of heuristic use (occurrence, suitability, and application\r\nof heuristics) are positively related to problem-solving success. When comparing\r\nthe predictive capacity of all three aspects, we identified the correct application of\r\nheuristics as particularly conducive for better problem-solving success. In comparing\r\nthe group of students with high to those with low initial math competence, we find no significant differences in the relationship between heuristic use and problemsolving\r\nsuccess across achievement groups. Our results emphasize the crucial role\r\nof heuristic application in mathematical problem solving, which generally benefits\r\nstudents regardless of their overall math competence.","lang":"eng"}],"publication":"Journal für Mathematik-Didaktik","issue":"6","department":[{"_id":"97"}],"type":"journal_article","date_created":"2026-06-15T10:08:04Z","file":[{"creator":"rheroldb","date_created":"2026-06-15T10:03:48Z","file_name":"2026_JMD_Herold-Blasius et al_Dimensions of heuristic use.pdf","access_level":"closed","file_size":1766182,"relation":"main_file","date_updated":"2026-06-15T10:03:48Z","file_id":"65866","content_type":"application/pdf","success":1}]},{"doi":"https://hal.science/hal-05334687v1","main_file_link":[{"open_access":"1","url":"https://hal.science/hal-05334687v1"}],"language":[{"iso":"eng"}],"date_updated":"2026-06-24T07:01:42Z","title":"Intertwining theory and practice: Design of planning phases in PD training to support effective teacher planning processes","year":"2026","author":[{"full_name":"Knaudt, Katharina","last_name":"Knaudt","first_name":"Katharina"},{"id":"126182","full_name":"Herold-Blasius, Raja","first_name":"Raja","last_name":"Herold-Blasius"},{"full_name":"Selter, Christoph","last_name":"Selter","first_name":"Christoph"}],"type":"conference","file":[{"file_name":"2025_CERME_Knaudt-348.pdf","file_size":925117,"access_level":"open_access","relation":"main_file","date_updated":"2026-06-15T10:10:02Z","file_id":"65881","content_type":"application/pdf","creator":"rheroldb","date_created":"2026-06-15T10:10:02Z"}],"date_created":"2026-06-15T10:10:05Z","publication":"Proceedings of the Fourteenth Congress of the European Society for Research in Mathematics Education (CERME14","user_id":"126182","ddc":["510"],"page":"1–8","_id":"65880","has_accepted_license":"1","status":"public","oa":"1","quality_controlled":"1","file_date_updated":"2026-06-15T10:10:02Z","citation":{"chicago":"Knaudt, Katharina, Raja Herold-Blasius, and Christoph Selter. “Intertwining Theory and Practice: Design of Planning Phases in PD Training to Support Effective Teacher Planning Processes.” In <i>Proceedings of the Fourteenth Congress of the European Society for Research in Mathematics Education (CERME14</i>, 1–8, 2026. <a href=\"https://hal.science/hal-05334687v1\">https://hal.science/hal-05334687v1</a>.","short":"K.

Es wird daher gefordert, dass sich der Mathema-tikunterricht verstärkt einer verstehensorientierten Förderung arithmetischer Basis-kompetenzen widmen soll. Hierfür müssen Lehrkräfte allerdings sensibilisiert, weiter- und fortgebildet werden. In diesem Beitrag wird ein Professionalisierungs-konzept für den Mathematikunterricht der Primarstufe vorgestellt, welches im Rah-men des bundesweiten Projekts „Schule macht stark“ (kurz: SchuMaS) entstanden ist. Konzeptionell verzahnt es im Besonderen Theorie und Praxis: Es werden Fort-bildungen in Form von Fachnetzwerktreffen konzipiert und durch praxisnahe Kernbotschaften wird die Anbindung an die eigene Unterrichtspraxis ermöglicht. Darüber hinaus werden zu diesen Kernbotschaften passende Praxiserprobungen für die unterrichtliche Umsetzung bereitgestellt und so aufbereitet, dass sie auch für den Transfer ins Kollegium geeignet sind. Ferner werden zur vertiefenden Ausei-nandersetzung mit zentralen didaktischen Ideen onlinebasierte Selbstlernmodule zur Verfügung gestellt. Das Konzept wurde über drei Jahre (2021–2024) entwi-ckelt, erprobt und evaluiert. Die Evaluationsergebnisse zum Gesamtkonzept und den einzelnen Komponenten (Fachnetzwerktreffen, Praxiserprobung, onlineba-sierte Selbstlernmodule und Transfer ins Kollegium) werden abschließend darge-stellt und diskutiert.","lang":"ger"}],"issue":"1","publication":"HLZ – Herausforderung Lehrer*innenbildung","main_file_link":[{"open_access":"1","url":"https://doi.org/10.11576/hlz-7624"}],"language":[{"iso":"ger"}],"date_updated":"2026-06-24T06:45:30Z","intvolume":"         8","year":"2025","title":"Ein Professionalisierungskonzept zur Verzahnung von Theorie und Praxis für den Mathematikunterricht der Primarstufe","author":[{"id":"126182","first_name":"Raja","last_name":"Herold-Blasius","full_name":"Herold-Blasius, Raja"},{"first_name":"Brandt","last_name":"Johanna","full_name":"Johanna, Brandt"},{"first_name":"Katharina","last_name":"Herold","full_name":"Herold, Katharina"},{"first_name":"Stefanie","last_name":"Gatzka","full_name":"Gatzka, Stefanie"},{"full_name":"Götze, Daniela","first_name":"Daniela","last_name":"Götze"},{"last_name":"Krüger","first_name":"Uta","full_name":"Krüger, Uta"},{"full_name":"Selter, Christoph","first_name":"Christoph","last_name":"Selter"}],"oa":"1","quality_controlled":"1","file_date_updated":"2026-06-15T10:10:38Z","citation":{"apa":"Herold-Blasius, R., Johanna, B., Herold, K., Gatzka, S., Götze, D., Krüger, U., &#38; Selter, C.
