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":[{"url":"https://doi.org/10.11576/hlz-7624","open_access":"1"}],"language":[{"iso":"ger"}],"date_updated":"2026-06-24T06:45:30Z","intvolume":"         8","title":"Ein Professionalisierungskonzept zur Verzahnung von Theorie und Praxis für den Mathematikunterricht der Primarstufe","year":"2025","author":[{"id":"126182","full_name":"Herold-Blasius, Raja","first_name":"Raja","last_name":"Herold-Blasius"},{"full_name":"Johanna, Brandt","first_name":"Brandt","last_name":"Johanna"},{"last_name":"Herold","first_name":"Katharina","full_name":"Herold, Katharina"},{"full_name":"Gatzka, Stefanie","last_name":"Gatzka","first_name":"Stefanie"},{"last_name":"Götze","first_name":"Daniela","full_name":"Götze, Daniela"},{"full_name":"Krüger, Uta","first_name":"Uta","last_name":"Krüger"},{"full_name":"Selter, Christoph","first_name":"Christoph","last_name":"Selter"}],"oa":"1","quality_controlled":"1","file_date_updated":"2026-06-15T10:10:38Z","citation":{"short":"R.

In this article we discuss two candidates for what could be the tropicalization of $G$.\r\n  Our first suggestion is the extended affine building associated to $G$. This perspective makes makes use of Berkovich's embedding of the extended affine building into the Berkovich analytic space $G^{\\textrm{an}}$ and expands on work of Mumford by associating a toroidal bordification of $G$ to the choice of stacky fan in the building. We show that the natural retraction onto the building is compatible with the tropicalization map associated to a toroidal bordification.\r\n  Our second suggestion is a Weyl chamber of $G$, a special instance of spherical tropicalization, where we think of $G$ as a spherical $G\\times G$-variety with respect to left-right-multiplication. We show that the spherical tropicalization map may be identified with the toroidal tropicalization map associated to a wonderful compactification of $G$. This map also has a moduli-theoretic interpretation expanding on the compactifications of $G$ as moduli spaces of framed $\\mathbb{G}_m$-equivariant principal bundles on chains of projective lines introduced by Martens and Thaddeus.","lang":"eng"}],"_id":"66304","language":[{"iso":"eng"}],"user_id":"82981","author":[{"full_name":"Coles, Desmond","last_name":"Coles","first_name":"Desmond"},{"id":"114697","first_name":"Martin","last_name":"Ulirsch","full_name":"Ulirsch, Martin"}],"title":"Towards the tropicalization of reductive groups","status":"public","year":"2025","date_updated":"2026-07-08T06:19:31Z"},{"language":[{"iso":"eng"}],"_id":"66303","user_id":"82981","status":"public","year":"2025","title":"Tropical reductive groups and principal bundles on metric graphs","author":[{"full_name":"Gross, Andreas","first_name":"Andreas","last_name":"Gross"},{"full_name":"Kuhrs, Arne","first_name":"Arne","last_name":"Kuhrs"},{"full_name":"Ulirsch, Martin","last_name":"Ulirsch","first_name":"Martin","id":"114697"},{"full_name":"Zakharov, Dmitry","first_name":"Dmitry","last_name":"Zakharov"}],"date_updated":"2026-07-08T06:19:02Z","external_id":{"arxiv":["2511.05422"]},"date_created":"2026-07-08T06:18:46Z","type":"preprint","publication":"arXiv:2511.05422","citation":{"apa":"Gross, A., Kuhrs, A., Ulirsch, M., &#38; Zakharov, D.
