Das sprachliche Fähigkeitsselbstkonzept im Kontext multilingualer Schulklassenkomposition
Get PDFKontextmerkmale bilden einen Rahmen für soziale Vergleichsprozesse und beeinflussen akademische Fähigkeitsselbstkonzepte (FSK). In dieser Arbeit wird der Einfluss von schulischen Kontextmerkmalen auf das soziale und absolute FSK im Schulfach Deutsch untersucht. Dabei werden die Leistungsstärke der Klasse, die wahrgenommene soziale Bezugsnormorientierung der Lehrkräfte (WBNO) und die Mehrsprachigkeit der Schülerinnen und Schüler (SuS) als Kontextmerkmale berücksichtigt. 946 SuS aus 44 Klassen der Sekundarstufe 1 bearbeiteten einen Fragebogen und einen Leseverständnistest (LGVT 6-12). Mehrebenenanalytische Auswertungen zeigten, dass die Leistungsstärke der Klasse, unter der Kontrolle der individuellen Leistung, einen negativen Effekt auf die FSK hat. Damit wurde hier die Hypothese eines Big-Fish-Little-Pond-Effect (BFLPE) für das Schulfach Deutsch bestätigt. Der erwartete Moderatoreffekt der WBNO auf den BFLPE blieb dagegen aus. Weiter zeigte sich, unter Kontrolle individueller Leistung, hypothesenkonform ein positiver Effekt der multilingualen Schulklassenkomposition auf das soziale FSK, der für das absolute FSK dagegen nicht bestätigt wurde. Gleichzeitig bestätigte sich, dass SuS, die andere Familiensprachen als Deutsch verwenden, im Leseverständnistest durchschnittlich schlechtere Leistungen erzielen. Implikationen für die Praxis werden diskutiert
Evaluation einer hochschuldidaktischen Weiterbildung an der Medizinischen Fakultät Heidelberg
No full textDie Dozentenschulung (DOS) der Medizinischen Fakultät Heidelberg ist eine hochschuldidaktische Weiterbildung. Die DOS soll die Lehrkompetenz der Lehrenden stärken, sie motivieren, studierendenzentrierte Lehre umzusetzen und die Lernziele in ihren Lehrveranstaltungen transparent zu machen. Es wurden verschiedene Studien durchgeführt um diese Annahmen zu prüfen: Eine Fragebogenstudie zur Selbsteinschätzung der Lehrenden, eine Beobachtungsstudie zur Erfassung des Lehrverhaltens, eine Studierendenbefragung zur Wahrnehmung der Lehre und eine Trainerbefragung zur Identifikation der wichtigsten Ziele der DOS. Die Ergebnisse zeigen die Wirksamkeit der DOS auf verschiedenen Zielebenen auf und geben Hinweise für die formative Evaluation der DOS. Mit dem in dieser Arbeit entworfenen Beobachtungsbogen für Lehrveranstaltungen (BEO-LV) liegt zudem nun ein Instrument vor, das in hochschuldidaktischen Evaluationen auf der Verhaltensebene eingesetzt werden kann, um studierendenzentrierte und lehrendenzentrierte Merkmale der Lehre zu messen
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Zusammen sind wir weniger allein? Effekte der Campusschließungen auf Motivation und Emotion von Studierenden
No full textFear of the pandemic, loss of part-time jobs, online classes, and sometimes very limited opportunities for social interaction have all contributed to a sharp increase in students' experience of stress over the past two years. The result has been an increase in mental illness and thus a steadily rising need for psychological counseling. Policymakers in some states are now responding by increasing funding for psychological counseling at universities. However, current studies point above all to the social isolation of students, which still exists two years after the start of the pandemic. What are the consequences for the actors in the higher education system, especially in the field of student counseling, teaching and coaching
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
