Ausgehend von dieser Problematik wurde mithilfe von Analysen verschiedener Konzeptualisierungen von FDW und dem im angloamerikanischen Raum geläufigen Konzept des pedagogical content knowledge (PCK) ein differenziertes Modell Physikdidaktischen Wissens entworfen. Dieses dient als Grundlage für die Entwicklung eines schriftlichen Testinstruments auf Basis der Item-Response-Theorie, welches bundesweit an 12 Universitäten eingesetzt wurde. Um die Validität der intendierten Testwertinterpretation zu prüfen, wurden mehrere Begleituntersuchungen durchgeführt. Daran anschließend konnte das Testinstrument optimiert werden. Das Instrument ist für die Analysen auf Subskalenebene geeignet und kann für weiterführende Zusammenhangsanalysen bezüglich der Wissensbereiche des Professionswissens untereinander und des Zusammenhangs von Wissen und Handeln genutzt werden. Mithilfe einer differenzierten Aufklärung dieser Wirkzusammenhänge ist gegebenenfalls die Formulierung von Ansätzen zur Verbesserung der universitären Ausbildungsqualität möglich. }}, author = {{Gramzow, Yvonne}}, isbn = {{978-3-8325-3931-3}}, keywords = {{Fachdidaktisches Wissen Physiklehrkräfte}}, publisher = {{Logos Verlag}}, title = {{{Fachdidaktisches Wissen von Lehramtsstudierenden im Fach Physik: Modellierung und Testkonstruktion}}}, volume = {{181}}, year = {{2015}}, } @article{4332, abstract = {{LiTaO3 and LiNbO3 crystals are investigated here in a combined experimental and theoretical study that uses Raman spectroscopy in a complete set of scattering geometries and corresponding density-functional theory calculations to provide microscopic information on their vibrational properties. The Raman scattering efficiency is computed from first principles in order to univocally assign the measured Raman peaks to the calculated eigenvectors. Measured and calculated Raman spectra are shown to be in qualitative agreement and confirm the mode assignment by Margueron et al. [J. Appl. Phys. 111, 104105 (2012)], thus finally settling a long debate. While the two crystals show rather similar vibrational properties overall, the E-TO9 mode is markedly different in the two oxides.
