Force-displacement measurements and macrosections are commonly used methods to validate numerical models of clinching processes. However, these ex-situ methods often lead to springback of elastic deformations and crack-closing after unloading. In contrast, the in-situ computed tomography (CT) can provide three-dimensional images of the clinching point under loading conditions. So far, the quantity of elastic springback that causes measuring deviations between in- and ex-situ measurements is not determined. In this paper, a method is described to quantitatively compare the results of in-situ CT, ex-situ CT and CT scans of cut specimens, which are prepared for macrosectioning, among each other. The method is applied to a single-lap shear test of two clinched aluminum sheets. Here, the test is conducted to specific process steps, then the specimen is CT scanned in-situ (during loading) and ex-situ (after unloading). Subsequently, the specimens are cut for macrosectioning and CT scanned. Finally, the outer contours and the interfaces of cross section images are determined by digital image analysis and the deviations over the clinching point between ex- and in-situ methods are calculated. }}, author = {{Köhler, Daniel and Kupfer, Robert and Troschitz, Juliane and Gude, Maik}}, booktitle = {{Materials Research Proceedings}}, issn = {{2474-395X}}, publisher = {{Materials Research Forum LLC}}, title = {{{Comparison of ex- and in-situ investigations of clinched single-lap shear specimens}}}, doi = {{10.21741/9781644902417-20}}, year = {{2023}}, } @inbook{51194, author = {{Köhler, Daniel and Stephan, Richard and Kupfer, Robert and Troschitz, Juliane and Brosius, Alexander and Gude, Maik}}, booktitle = {{Lecture Notes in Production Engineering}}, isbn = {{9783031183171}}, issn = {{2194-0525}}, publisher = {{Springer International Publishing}}, title = {{{In-situ Computed Tomography and Transient Dynamic Analysis of a Single-Lap Shear Test with a Composite-Metal Clinch Point}}}, doi = {{10.1007/978-3-031-18318-8_28}}, year = {{2023}}, } @article{31189, abstract = {{Given a geometrically finite hyperbolic surface of infinite volume it is a classical result of Patterson that the positive Laplace-Beltrami operator has no $L^2$-eigenvalues $\geq 1/4$.

To prepare them adequately for the demands of their future teaching profession, it is essential to know (i) which subject-specific competences and skills they need and (ii) how these can be acquired in teacher education. However, empirical findings on necessary competences as well as on the design of teacher training courses are scarcely available on the subject of technology, since mainly general, normative recommendations on potential study contents exist. To fill this gap, this work focuses on the investigation of necessary practical competences of prospective technology teachers. The acquisition of such practical competences and skills is of great importance for the school subject of technology when, for example, machines are operated, tools are used, or objects are designed and manufactured. However, there is a lack of a differentiated description of the practical requirements for technology teachers and the teaching-learning processes required for this in the teacher training. The aim of this work is therefore the theory- and empirically-guided development and evaluation of a practical demand-oriented course for the technology teacher training programme at RWTH Aachen University to promote subject-specific practical competences. The development was structured as an iterative process by the Model of Educational Reconstruction (MER), according to which three major aspects were investigated and connected. (1) In a first step, the competences to be acquired were described and structured, taking normative perspectives into account as well as an empirical needs assessment among teachers and teacher educators to clarify and analyse the science subject matter. (2) In a second step, the student teacher´s perspective was surveyed to adapt the course to their initial competences, skills and experiences. (3) In a third step, the content and the didactic structure of the practical course was developed iteratively, considering the findings of the preceding steps and various requirements for the design and the tasks of the practical course (e.g., a necessary differentiation or a self-directed examination of the practical tasks in the course). The practical course was taught in several runs and evaluated with respect to the perceived learning outcomes of the student teachers as well as to the quality of the course. The evaluation was carried out through self-assessment of the students in a questionnaire and a written portfolio. The findings of the evaluation indicate a positive perception regarding the quality of the course. The students positively assessed the course structure (e.g., sequence of the course contents) and individual course elements (e.g., concrete course tasks). Furthermore, an increase in practical competences and skills – regardless of initial experience – was found. The work provides groundwork for further studies, for example on the level of competence acquisition or the long-term effect of the practical course.}}, author = {{Ermel, Dorothee Leonie}}, publisher = {{RWTH Aachen University}}, title = {{{Entwicklung und Evaluation eines Fachpraktikums für das Lehramtsstudium Technik zur Förderung fachpraktischer Kompetenzen}}}, doi = {{10.18154/RWTH-2023-03787}}, year = {{2023}}, } @inbook{46182, author = {{Drepper, Laura and Herrmann, Franziska and Nußbaum, Alena}}, booktitle = {{Schreibunterricht.

Empirische Grundlagen sind standardisierte Eltern- und Kinderbefragungen sowie ethnografisch orientierte Untersuchungen in Familien. Die quantitativen Analysen zeigen, dass Kinder, deren Hauptverkehrssprache in der Familie nicht Deutsch ist, häufiger gemeinsam mit ihren Eltern das Internet nutzten. Vertiefend liessen in der qualitativen Untersuchung diejenigen Kinder häufigere und komplexere Internetnutzungsformen für schulische Zwecke erkennen, die einen Migrationshintergrund aufweisen und hauptsächlich in ihrer Herkunftssprache (nicht Deutsch) innerhalb der Familie sprechen. Insbesondere in Familien, die selten in der Häuslichkeit Deutsch sprechen, hat sich die (gemeinsame) Internetrecherche als Mittel zur Kompensation von Sprachbarrieren erwiesen. Fehlende elterliche Unterstützungsmöglichkeiten aufgrund von sprachlichen Verständnisproblemen können insofern durch kindliche, elterliche oder gemeinsame Rechercheprozesse ausgeglichen werden.}}, author = {{Richter, Lea and Gruchel, Nicole and Buhl, Heike M. and Kamin, Anna-Maria}}, issn = {{1424-3636}}, journal = {{MedienPädagogik: Zeitschrift für Theorie und Praxis der Medienbildung}}, keywords = {{General Medicine}}, pages = {{293--319}}, publisher = {{Sektion Medienpadagogik der Deutschen Gesellschaft fur Erziehungswissenschaft - DGfE}}, title = {{{Herkunftsbedingte und sprachliche Einflüsse bei der häuslichen Internetnutzung von Kindern}}}, doi = {{10.21240/mpaed/jb20/2023.09.12.x}}, year = {{2023}}, }
