Reflexion als zentrales Element von Service Learning. Eine theoretische Bestimmung
No full textAls zentrales Lernelement beim Service Learning gilt, dass Studierende über die Erfahrungen, die sie während ihrer praktischen Tätigkeit beim Service machen, nachdenken. Dieser Reflexionsprozess, den wir als bewusste, gerichtete Erwägung vergangener Erfahrungen im Hinblick auf festgelegte Ziele definieren, ist unzureichend expliziert und empirisch wenig untersucht. Wir nehmen an, dass überraschende negative oder positive Erlebnisse, die als bedeutsam erscheinen, Reflexionen auslösen. Studierende können darauf abhängig von Ursachenattributionen mit einer von drei Kategorien reagieren: Verleugnung, Assimilation und Adaptation. Wir fragen, welche kognitiven Operationen aktiviert werden müssen, damit die jeweils beim Service Learning verfolgten Ziele (Theorie-Praxis-Verständnis, Persönlichkeitsentwicklung und gesellschaftliche Einstellungen) erreicht werden können. Das Modell dient unter anderem dazu, Leitfragen zu generieren, um angestrebte Reflexionsprozesse zu unterstützen
Motivational interference in school-leisure conflict and learning outcomes: The differential effects of two value conceptions
No full textHofer M, Kuhnle C, Kilian B, Marta E, Fries S. Motivational interference in school-leisure conflict and learning outcomes: The differential effects of two value conceptions. Learning and Instruction. 2011;21(3):301-316.It was hypothesized that students' value orientations are connected to their experience of motivational interference in a conflict between a school- and a leisure-related activity as well as to school marks as indicators of learning outcomes. In a self-report study with Italian adolescents (N = 433; M = 14.5 years) using a school-leisure conflict scenario, first, the relations between the 10 values introduced by Schwartz and the Inglehart-based Achievement and Well-being value orientations were investigated. Correlations and multidimensional scaling analysis showed overlaps as well as differences between the two sets of value variables. Regression analyses revealed that the Schwartz values were significantly related to the experience of motivational interference during studying and during leisure as well as to school marks. The inclusion of Achievement and Well-being value orientations explained additional variance of the three dependent variables. The relevance of individual values in explaining students' reactions to motivational conflicts is highlighted
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
