A great number of Central Asian wall paintings, archeological materials, architectural fragments, and textiles, as well as painting fragments on silk and paper, make up the so called Turfan Collection at the Asian Art Museum in Berlin. The largest part of the collection comes from the Kucha region, a very important cultural center in the third to ninth centuries. Between 1902 and 1914, four German expeditions traveled along the northern Silk Road. During these expeditions, wall paintings were detached from their original settings in Buddhist cave complexes. This paper reports a technical study of a wall painting, existing in eight fragments, from the Buddhist cave no. 40 (Ritterhöhle). Its original painted surface is soot blackened and largely illegible. Grünwedel, leader of the first and third expeditions, described the almost complete destruction of the rediscovered temple complex and evidence of fire damage. The aim of this case study is to identify the materials used for the wall paintings. Furthermore, soot deposits as well as materials from conservation interventions were of interest. Non-invasive analyses were preferred but a limited number of samples were taken to provide more precise information on the painting technique. By employing optical and scanning electron microscopy, energy dispersive X-ray spectroscopy, micro X-ray fluorescence spectroscopy, X-ray diffraction analysis, and Raman spectroscopy, a layer sequence of earthen render, a ground layer made of gypsum, and a paint layer containing a variety of inorganic pigments were identified.  相似文献

Influence of Previous Knowledge, Language Skills and Domain-specific Interest on Observation Competency     

Lucia Kohlhauf  Ulrike Rutke  Birgit Neuhaus 《Journal of Science Education and Technology》2011,20(5):667-678

Many epoch-making biological discoveries (e.g. Darwinian Theory) were based upon observations. Nevertheless, observation is often regarded as ‘just looking’ rather than a basic scientific skill. As observation is one of the main research methods in biological sciences, it must be considered as an independent research method and systematic practice of this method is necessary. Because observation skills form the basis of further scientific methods (e.g. experiments or comparisons) and children from the age of 4 years are able to independently generate questions and hypotheses, it seems possible to foster observation competency at a preschool level. To be able to provide development-adequate individual fostering of this competency, it is first necessary to assess each child’s competency. Therefore, drawing on the recent literature, we developed in this study a competency model that was empirically evaluated within learners (N = 110) from different age groups, from kindergarten to university. In addition, we collected data on language skills, domain-specific interest and previous knowledge to analyse coherence between these skills and observation competency. The study showed as expected that previous knowledge had a high impact on observation competency, whereas the influence of domain-specific interest was nonexistent. Language skills were shown to have a weak influence. By utilising the empirically validated model consisting of three dimensions (‘Describing’, ‘Scientific reasoning’ and ‘Interpreting’) and three skill levels, it was possible to assess each child’s competency level and to develop and evaluate guided play activities to individually foster a child’s observation competency.  相似文献   

Der Einfluss von Lehrervorstellungen zum Lernen und Lehren auf die Gestaltung des Unterrichts und auf motivationale Schülervariablen

Es gibt einige Hinweise darauf, dass Vorstellungen vom Lehren und Lernen sowohl für das Handeln der Lehrkr?fte im Unterricht als auch für Zielkriterien auf der Ebene der Schüler eine Rolle spielen. Dabei gelten konstruktivistisch orientierte Sichtweisen als besonders günstig. Empirische Untersuchungen dazu gibt es jedoch bislang nur auf einzelne fachdidaktische Inhaltsbereiche bezogen. In der vorliegenden Studie werden konstruktivistisch orientierte Lehrereinstellungen mit Merkmalen des Unterrichts (?ffnung des Unterrichts im Hinblick auf Entscheidungsm?glichkeiten für Schüler/-innen und Strukturierung des Unterrichts) sowie mit Einsch?tzungen der Schüler/-innen (Selbstbestimmungsempfinden und Interessantheit des Unterrichts) in Beziehung gesetzt. Die Ergebnisse best?tigen die Theorie: In den Klassen der Lehrer/-innen mit überwiegend konstruktivistischen Vorstellungen von Lernen und Lehren gibt es mehr Freir?ume, ohne dass der Unterricht weniger strukturiert abl?uft. Zudem empfinden sich die Schüler/-innen als selbstbestimmter und sch?tzen den Unterricht als interes-santer ein.  相似文献

Dopaminerge Modulation striataler Plastizität     

Frieder Beck  Klaus Blischke  Birgit Abler 《Sportwissenschaft》2012,42(4):271-279

This article attempts to outline the neuronal foundations of movement automatization. In particular, it is shown that an increase in automaticity corresponds to processes of synaptic plasticity in the corticostriatal and corticocortical system. This mechanism is supposed to induce changes in the neuronal representations of the respective skill. Furthermore, the role of phasic dopamine release will be discussed with respect to its modulating effect on processes of plasticity.  相似文献
