To explore how relations between these specific skills change over the course of a field experience controlling for influences of professional knowledge, we conduct a pre-post field study with N = 95 preservice physics teachers in a one-semester field experience. Content knowledge (CK) and pedagogical content knowledge (PCK) (paper-and-pencil tests), and reflection and planning skills (standardized performance assessments) were assessed before and after the field experience. Path analyses revealed almost no influence of reflection skills on planning skills. Reflections skills did not contribute to preservice teachers planning skills beyond knowledge, indicating both constructs might represent rather independent abilities. The results show the need for further development of models describing the development of teachers’ professional knowledge and skills in academic teacher education and for the development of concepts for a better integration of reflection and lesson planning in field experiences.</jats:p>"}],"date_created":"2023-01-09T15:25:28Z","publisher":"MDPI AG","title":"Learning to Plan by Learning to Reflect?—Exploring Relations between Professional Knowledge, Reflection Skills, and Planning Skills of Preservice Physics Teachers in a One-Semester Field Experience","issue":"7","year":"2022","department":[{"_id":"299"},{"_id":"33"}],"user_id":"4245","_id":"35522","article_number":"479","type":"journal_article","status":"public","volume":12,"author":[{"first_name":"Christoph","last_name":"Vogelsang","id":"4245","full_name":"Vogelsang, Christoph"},{"full_name":"Kulgemeyer, Christoph","last_name":"Kulgemeyer","first_name":"Christoph"},{"full_name":"Riese, Josef","last_name":"Riese","first_name":"Josef"}],"date_updated":"2023-01-09T15:27:20Z","doi":"10.3390/educsci12070479","publication_identifier":{"issn":["2227-7102"]},"publication_status":"published","intvolume":"        12","citation":{"ieee":"C.

In dieser Arbeit wird den übergeordneten Fragestellungen nachgegangen, inwiefern es Lehramtsstudierenden durch Reflexionsgelegenheiten im Studium gelingt, ihr theoretisches Wissen mit praktischen Erfahrungen in Beziehung zu setzen und in welchem Zusammenhang die Reflexionskompetenz zu bestimmten Fördermaßnahmen (Portfolioarbeit) und Settings (Microteaching) sowie zu anderen Facetten professioneller Handlungskompetenz (Professionswissen, Einstellungen, Motivation) steht. Auf Basis einer kompetenztheoretischen Modellierung von Reflexion wurde hierzu die Reflexionsperformanz von Lehramtsstudierenden erfasst, um Rückschlüsse auf reflexionsbezogene Denkprozesse ziehen zu können. Die Auswertungen erfolgten qualitativ inhaltsanalytisch und wurden an teilweise quantifiziert, um statistische Analysen durchführen zu können. Insgesamt zeigen die Befunde der drei Teilstudien, dass die Reflexionsperformanz insbesondere dann von höherer Qualität ist, wenn theoretische Inhalte explizit mit praktischen Erfahrungen relationiert werden. Positive Einstellungen gegenüber Reflexion unterstützen die Reflexionsperformanz.

In this study, the overarching questions are investigated to what extent student teachers succeed in relating their theoretical knowledge to practical experiences through reflection opportunities in their studies and how reflection competence is related to certain support measures (portfolio work) and settings (microteaching) as well as to other facets of professional action competence (professional knowledge, attitudes, motivation). Based on a competence-theoretical modelling of reflection, the reflective performance of student teachers was recorded in order to be able to draw conclusions about reflection-related thought processes. The evaluations were carried out qualitatively in terms of content analysis and were partially quantified in order to be able to carry out statistical analyses. Overall, the findings of the three sub-studies show that the reflective performance is of higher quality especially when theoretical contents are explicitly related to practical experiences. Positive attitudes towards reflection support reflection performance. The students' professional knowledge in educational science can also explain differences in reflective performance.","lang":"eng"}],"author":[{"last_name":"Meier","full_name":"Meier, Jana","first_name":"Jana"}],"supervisor":[{"first_name":"Niclas","full_name":"Schaper, Niclas","last_name":"Schaper"},{"first_name":"Bardo","full_name":"Herzig, Bardo","id":"217","last_name":"Herzig"}],"date_created":"2022-06-13T08:12:43Z","publisher":"Universität Paderborn","date_updated":"2023-01-09T17:17:32Z","doi":"10.17619/UNIPB/1-1274","title":"„LauRa - In der Lehramtsausbildung Reflexionskompetenz analysieren“.

This is ascribed to a temporary self-catalyzed vapor–liquid–solid growth on [Formula: see text] B facets, which leads to a kinetically induced preference for the nucleation of the wurtzite phase driven by the local, instantaneous V/III ratio, and to a concomitant reduction of surface energy of the nanoscale diameter arms. </jats:p>","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["General Physics and Astronomy"],"issue":"18","year":"2022","date_created":"2022-11-10T14:19:21Z","publisher":"AIP Publishing","title":"Selective area heteroepitaxy of InAs nanostructures on nanopillar-patterned GaAs(111)A"},{"publication_status":"published","publication_identifier":{"issn":["2196-7350","2196-7350"]},"citation":{"bibtex":"@article{Riedl_Kunnathully_Trapp_Langer_Reuter_Lindner_2022, title={Size‐Dependent Strain Relaxation in InAs Quantum Dots on Top of GaAs(111)A Nanopillars}, volume={9}, DOI={<a href=\"https://doi.org/10.1002/admi.202102159\">10.1002/admi.202102159</a>}, number={112102159}, journal={Advanced Materials Interfaces}, publisher={Wiley}, author={Riedl, Thomas and Kunnathully, Vinay and Trapp, Alexander and Langer, Timo and Reuter, Dirk and Lindner, Jörg}, year={2022} }","short":"T.

We consider spherical clusters, thick layers and monolayers with realistic topologies and dimensions much larger than the wavelength of light. The maximum bulk packing density of clusters is 0.5. A numerically exact solution of the electromagnetic problem is obtained using the Discontinuous Galerkin Time Domain method and with application of high- performance computing. We show that high packing density causes light localization in such structures which makes an impact on the opposition phenomena: backscattering intensity surge and negative linear polarization feature. Diffuse multiple scattering is significantly reduced in the case of non-absorbing particles and near-field interaction results in a percolation-like light transport determined by the topology of the medium. With this the negative polarization feature caused by single scattering gets enhanced if compared to lower density samples. We also confirm coherent double scattering mechanism of negative polarization for light scattered from dense absorbing slabs. In this case convergent result for the scattering angle polarization dependency at backscattering can be obtained for a layer of just a few tens of particles if they are larger than the wavelength.","lang":"eng"}],"date_created":"2022-09-22T09:18:45Z","publisher":"Springer International Publishing","title":"Light Scattering by Large Densely Packed Clusters of Particles","year":"2022"},{"citation":{"ieee":"V.

Thin foils for combined STEM and SEM experiments were prepared by electrolytic twin-jet polishing. They were in-situ heated in a TEM heating stage and observed at 200 kV in the JEOL JEM 2200FS electron microscope equipped with STEM HAADF and BF detectors and SEM BSE and SE detectors working both in composition and topographic modes. The resulting structures were combined with EDS mapping performed directly in the heating holder. Dissolution and transformation of Cu- and Fe-rich particles occur above 500 °C. EDS maps acquired on the foil cooled down to room temperature show that Cu and Fe are both still present in newly formed particles, most likely indicating the presence of the Al7Cu2Fe phase.","lang":"eng"}],"publication":"METAL 2022 Conference Proeedings","title":"HOMOGENIZATION OF TWIN-ROLL CAST Al-Li-BASED ALLOY STUDIED BY IN-SITU ELECTRON MICROSCOPY","date_created":"2023-01-12T09:39:41Z","publisher":"TANGER Ltd.","year":"2022"},{"year":"2022","issue":"5","title":"Laser-lithographically written micron-wide superconducting nanowire single-photon detectors","publisher":"IOP Publishing","date_created":"2022-10-11T07:14:11Z","abstract":[{"text":"<jats:title>Abstract</jats:title>\r\n               <jats:p>We demonstrate the fabrication of micron-wide tungsten silicide superconducting nanowire single-photon detectors on a silicon substrate using laser lithography.

We present a method to replace the electrical input by supplying the required bias current via the photocurrent of a photodiode situated on the cold stage of the cryostat. Light is guided to the bias photodiode through an optical fiber, which enables a lower thermal conduction and galvanic isolation between room temperature and the cold stage. We show that an off-the-shelf InGaAs–InP photodiode exhibits a responsivity of at least 0.55 A/W at 0.8 K. Using this device to bias an SNSPD, we characterize the count rate dependent on the optical power incident on the photodiode. This configuration of the SNSPD and photodiode shows an expected plateau in the single photon count rate with an optical bias power on the photodiode above 6.8 µW. Furthermore, we compare the same detector under both optical and electrical bias, and show there is no significant changes in performance. This has the advantage of avoiding an electrical input cable, which reduces the latent heat load by a factor of 100 and, in principle, allows for low loss RF current supply at the cold stage. </jats:p>"}],"status":"public","_id":"33673","user_id":"83846","department":[{"_id":"15"},{"_id":"230"},{"_id":"623"}],"article_number":"081303","keyword":["Computer Networks and Communications","Atomic and Molecular Physics","and Optics"],"language":[{"iso":"eng"}]},{"page":"19-32","citation":{"ieee":"S.

In this paper\r\nwe investigate the hardness of classically simulating the QSVT. A recent result\r\nby Chia, Gily\\'en, Li, Lin, Tang and Wang (STOC 2020) showed that the QSVT can\r\nbe efficiently \"dequantized\" for low-rank matrices, and discussed its\r\nimplication to quantum machine learning. In this work, motivated by\r\nestablishing the superiority of quantum algorithms for quantum chemistry and\r\nmaking progress on the quantum PCP conjecture, we focus on the other main class\r\nof matrices considered in applications of the QSVT, sparse matrices.\r\n  We first show how to efficiently \"dequantize\", with arbitrarily small\r\nconstant precision, the QSVT associated with a low-degree polynomial. We apply\r\nthis technique to design classical algorithms that estimate, with constant\r\nprecision, the singular values of a sparse matrix. We show in particular that a\r\ncentral computational problem considered by quantum algorithms for quantum\r\nchemistry (estimating the ground state energy of a local Hamiltonian when\r\ngiven, as an additional input, a state sufficiently close to the ground state)\r\ncan be solved efficiently with constant precision on a classical computer. As a\r\ncomplementary result, we prove that with inverse-polynomial precision, the same\r\nproblem becomes BQP-complete. This gives theoretical evidence for the\r\nsuperiority of quantum algorithms for chemistry, and strongly suggests that\r\nsaid superiority stems from the improved precision achievable in the quantum\r\nsetting. We also discuss how this dequantization technique may help make\r\nprogress on the central quantum PCP conjecture."}],"publication":"Proceedings of the 54th ACM Symposium on Theory of Computing (STOC)","type":"conference","language":[{"iso":"eng"}],"department":[{"_id":"623"},{"_id":"7"}],"user_id":"71541","_id":"27531","external_id":{"arxiv":["2111.09079"]}}]
