@article{45562, abstract = {{AbstractBased on a literature review of studies on teachers’ professional competence and related assessment tools, this paper introduces a model of teacher education assessment. It is influenced by Miller’s (1990) framework of assessment in medical education and includes, among other aspects, performance assessments. This model is used to understand the potential effects of transferring assessment tools into a digital format with assessment feedback. Five examples for such a transfer will be discussed: three methods for various aspects of communication, a test for pedagogical content knowledge, and a test for content knowledge. All five are established instruments well-described in terms of validity. All five have recently been transferred into a digital format. The analysis of this transfer also reveals a potentially harmful effect of digital assessment. The closer an assessment instrument is to assessing action-related parts of professional competence, the more authenticity is required; however, digitisation tends to decrease this authenticity. This suggests that an increasing number of digital assessment tools in teacher education might result in an even more dominant focus on knowledge tests, ignoring other parts of professional competence. This article highlights the role of authenticity in validity and discusses the most suitable assessment format to address various parts of professional competence. It ends by highlighting the lessons learned from the transfer of assessment instruments into a digital format that other academic disciplines might find interesting.}}, author = {{Kulgemeyer, Christoph and Riese, Josef and Vogelsang, Christoph and Buschhüter, David and Borowski, Andreas and Weißbach, Anna and Jordans, Melanie and Reinhold, Peter and Schecker, Horst}}, issn = {{1434-663X}}, journal = {{Zeitschrift für Erziehungswissenschaft}}, keywords = {{Education}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{How authenticity impacts validity: Developing a model of teacher education assessment and exploring the effects of the digitisation of assessment methods Über Validität und Authentizität: Effekte des Transfers von Testinstrumenten in ein digitales Format auf die erhobenen Aspekte der professionellen Handlungskompetenz}}}, doi = {{10.1007/s11618-023-01154-y}}, year = {{2023}}, } @inproceedings{45563, author = {{Große-Heilmann, Rike Isabel and Burde, Jan-Philipp and Riese, Josef and Schubatzky, Thomas and Weiler, David}}, booktitle = {{Lernen, Lehren und Forschen in einer digital geprägten Welt Gesellschaft für Didaktik der Chemie und Physik Jahrestagung in Aachen 2022}}, editor = {{van Vorst, Helena}}, pages = {{107--110}}, title = {{{Erwerb und Messung fachdidaktischen Wissens zum Einsatz digitaler Medien}}}, year = {{2023}}, } @inproceedings{45566, author = {{Jordans, Melanie and Riese, Josef}}, booktitle = {{Lernen, Lehren und Forschen in einer digital geprägten Welt Gesellschaft für Didaktik der Chemie und Physik Jahrestagung in Aachen 2022}}, editor = {{van Vorst, Helena}}, pages = {{794--797}}, title = {{{Unterrichtsplanung mit sinnvoller Einbettung digitaler Medien im PU}}}, year = {{2023}}, } @inproceedings{45565, author = {{Zeller, Jannis and Riese, Josef}}, booktitle = {{Lernen, Lehren und Forschen in einer digital geprägten Welt Gesellschaft für Didaktik der Chemie und Physik Jahrestagung in Aachen 2022}}, editor = {{van Vorst, Helena}}, pages = {{786--789}}, title = {{{Datenbasierte Fähigkeitsprofile im Physikdidaktischen Wissen}}}, year = {{2023}}, } @phdthesis{45580, author = {{Castenow, Jannik}}, title = {{{Local Protocols for Contracting and Expanding Robot Formation Problems}}}, doi = {{10.17619/UNIPB/1-1750}}, year = {{2023}}, } @phdthesis{45579, author = {{Knollmann, Till}}, title = {{{Online Algorithms for Allocating Heterogeneous Resources}}}, doi = {{10.17619/UNIPB/1-1751}}, year = {{2023}}, } @article{45596, abstract = {{Dielectric metasurfaces provide a unique platform for efficient harmonic generation and optical wavefront manipulation at the nanoscale.

Here, we propose a simple yet effective approach combining a sampling method with a Monte Carlo approach to design the third-harmonic wavefront generated by all-dielectric metasurfaces composed of elliptical silicon nanodisks. Using this approach, we theoretically demonstrate the full nonlinear 2π phase control with a uniform and highest possible amplitude in the considered parameter space, allowing us to design metasurfaces operating as third harmonic beam deflectors capable of steering light into a desired direction with high emission efficiency. The TH beam deflection with a record calculated average conversion efficiency of 1.2 × 10–1 W–2 is achieved.

Quantum light involves more degrees of freedom than classical light as e.g., its photon statistics and quantum correlations, which is a promising resource for quantum devices, such as quantum memories. The light-matter interaction is treated with a Jaynes-Cummings type model and the quantum field is given by a single mode since the quantum dots are embedded in a microcavity. We present numerical simulations of the four-wave-mixing response of a homogeneous system for pulse sequences and find a significant dependence of the result on the photon statistics of the incident pulses.

Our results show that the proposed $\rm{DFT+U_p}$ methodology is computationally efficient, but still accurate. It can be applied to well-ordered TiO$\rm{_2}$ polymorphs as well as to amorphous TiO$\rm{_2}$ and will allow for the calculations of complex titania-based structures.}}, author = {{Badalov, Sabuhi and Bocchini, Adriana and Wilhelm, Rene and Kozub, A.

Life Cycle Engineering (LCE) based on Life Cycle Assessment (LCA) supports this by providing holistic information and improvement potentials regarding eco-efficient products. Key factors influencing LCAs of automotive components, such as material production, will change in the future. First approaches for integrating future scenarios for these key factors into LCE already exist, but they only consider a limited number of parameters and scenarios. This work aims to develop a method that can be practically applied in the industry for integrating prospective LCAs (pLCA) into the LCE of automotive components, considering relevant parameters and consistent scenarios. Therefore, pLCA methods are further developed to investigate the influence of future scenarios on the GHG emissions of automotive components. The practical application is demonstrated for a vehicle component with different design options. This paper shows that different development paths of the foreground and background system can shift the ecological optimum of design alternatives. Therefore, future pathways of relevant parameters must be considered comprehensively to reduce GHG emissions of future vehicles. This work contributes to the methodological and practical integration of pLCA into automotive development processes and provides quantitative results.}}, author = {{Grenz, Julian and Ostermann, Moritz and Käsewieter, Karoline and Cerdas, Felipe and Marten, Thorsten and Herrmann, Christoph and Tröster, Thomas}}, issn = {{2071-1050}}, journal = {{Sustainability}}, keywords = {{prospective LCA, life cycle engineering (LCE), lightweight design, automotive components, body parts, circular economy, steel, aluminum, hybrid materials, fiber metal laminates}}, number = {{13}}, publisher = {{MDPI AG}}, title = {{{Integrating Prospective LCA in the Development of Automotive Components}}}, doi = {{10.3390/su151310041}}, volume = {{15}}, year = {{2023}}, }
