Lernen trotz Corona

Die PH Niederösterreich bietet in einem kurzfristig initiierten Projekt Hilfestellungen, damit auch in der Zeit von Schutzmaßnahmen das Lernen gelingt. Es geht um die Prozesse beim Lernen zu Hause und das Kontakthalten der Lehrenden mit den Kindern – und untereinander. Organisatorische Hilfestellungen und didaktische Empfehlungen sind schnell in den Fokus gerückt, Informationen zur technischen Umsetzung des Distance Learnings wurden dabei aber nicht außer Acht gelassen. Die beachtliche Resonanz, die Vielzahl der Rückfragen, -meldungen und die hohe Anzahl an Seitenaufrufen während der Zeit der Schulschließungen bestätigen den Bedarf. Mit der Phase der Teilöffnung der Schulen stellt sich nunmehr die Frage, was von der Umsetzung von Distance Learnings nachhaltig im System Schule erhalten bleibt. In diesem Artikel wollen wir die Gründe, die Ziele und die Entstehungsgeschichte des Projektes Lernen trotz Corona beschreiben.In a project initiated at short notice, the University College of Teacher Education of Lower Austria offers assistance to ensure that learning is also successful during the period of protective measures. It is about the processes of learning at home and keeping the teachers in contact with the children - and each other. Organisational support and didactic recommendations quickly came into focus, but information on the technical implementation of distance learning was not neglected. The considerable response, the large number of queries and messages and the high number of page views during the school closures confirm the need. With the phase of partial opening of the schools, the question now arises as to what will be retained in the system school in the long term by the implementation of distance learning. In this article we want to describe the reasons, the goals and the history of the project Lernen trotz Corona

Lernen trotz Corona. Chancen und Herausforderungen des distance learning an österreichischen Schulen: Chancen und Herausforderungen des Distance Learnings an österreichischen Schulen

Ein aktuell laufendes Forschungsprojekt der Pädagogischen Hochschule Niederösterreich widmet sich der Frage, wie Eltern, Lehrkräfte und die Schulleitung die Phase des Distance Learnings erlebt haben und welche Schlussfolgerungen daraus für den regulären Unterricht gezogen werden können. Nach einer Beschreibung der Ausgangssituation und der Darstellung anderer, ähnlicher Studien sollen in diesem Artikel erste Ergebnisse dieses Forschungsprojekts präsentiert werden.A current research project of the University College of Teacher Education Training of Lower Austria examines the experiences of parents, teachers and school management during the distance learning phase and what conclusions can be drawn from it for regular teaching. After a detailed description of the initial situation and the presentation of other similar studies this article will present first results of this research project. &nbsp

Multipotent progenitors instruct ontogeny of the superior colliculus

The superior colliculus (SC) in the mammalian midbrain is essential for multisensory integration, attention, and complex behavior (Basso and May, 2017; Cang et al., 2018). The mature SC cytoarchitecture is organized into distinct laminae and composed of a rich variety of neuronal and glial cell types (Ayupe et al., 2023; Edwards et al., 1986; May, 2006; Xie et al., 2021; Zeisel et al., 2018). Precise execution of the developmental programs regulating the generation of SC cell-type diversity is essential, because deficits due to genetic mutations have been associated with neurodevelopmental diseases and SC dysfunction (Jure, 2018; McFadyen et al., 2020). However, the fundamentals directing the ontogeny of the SC are not well understood. Here we pursued systematic lineage tracing at the single progenitor cell level in order to decipher the principles instructing the generation of cell-type diversity in the SC. We combined in silico lineage reconstruction with a novel genetic MADM (Mosaic Analysis with Double Markers)-CloneSeq approach. MADM-CloneSeq enables the unequivocal delineation of cell lineages in situ, and cell identity based on global transcriptome, of individual clonally-related cells. Our systematic reconstructions of cell lineages revealed that all neuronal cell types in SC emerge from local progenitors without any extrinsic source. Strikingly, individual SC progenitors are exceptionally multipotent with the capacity to produce all known excitatory and inhibitory neuron types of the prospective mature SC, with individual clonal units showing no pre-defined composition. At the molecular level we identified an essential role for PTEN signaling in establishing appropriate proportions of specific inhibitory and excitatory neuron types. Collectively, our findings demonstrate that individual multipotent progenitors generate the full spectrum of excitatory and inhibitory neuron types in the developing SC, providing a novel framework for the emergence of cell-type diversity and thus the ontogeny of the mammalian SC
