No full textThis is a PSYNDEX Tests Review of MARKO-D - Mathematik- und Rechenkonzepte im Vorschulalter - Diagnose. PSYNDEX Tests Reviews are written in German and describe and evaluate psychological and educational tests used in the German-speaking countries. PSYNDEX Tests is offered by the Leibniz Institute for Psychology as open access documentation.Das ist ein PSYNDEX Tests Review zu MARKO-D - Mathematik- und Rechenkonzepte im Vorschulalter - Diagnose. PSYNDEX Tests Reviews beschreiben und bewerten zentrale psychologische und pädagogische Testverfahren, die in den deutschsprachigen Ländern eingesetzt werden, nach einem standardisierten Raster. PSYNDEX Tests wird durch das Leibniz-Institut für Psychologie als Open Access Dokumentation angeboten.Diagnostische Zielsetzung: Das Verfahren zur Erfassung von Mathematik- und Rechenkonzepten im Vorschulalter-Diagnose (MARKO-D) wurde entwickelt, um die mathematische Entwicklung von Kindern erfassen und bei Defiziten entsprechende Interventionsmaßnahmen rechtzeitig einleiten zu können. Inhaltlich basiert das Verfahren auf der Annahme, dass die Entwicklung mathematischer Fähigkeiten in fünf Stufen abläuft. Aufbau: Der Test besteht aus 55 Items zu 13 Subtests, welche Fähigkeiten in den fünf Niveaus Zählzahl (Niveau I), Ordinaler Zahlenstrahl (Niveau II), Kardinalität und Zerlegbarkeit (Niveau III), Enthaltensein und Klasseninklusion (Niveau IV) und Relationalität (Niveau V) erfassen. Grundlagen und Konstruktion: Zunächst wurden aus Theorien zur Entwicklung des Rechnen Lernens und der Early Numeracy-Forschung erste Items generiert und hinsichtlich Itemschwierigkeit und Trennschärfe analysiert. Aufgrund von Latent Class-Analysen wurde die Zuordnung der Items zu den einzelnen Niveaus untersucht. Nachdem einige Items nicht in das zugehörige Niveau passten, wurden sie überarbeitet. Empirische Prüfung und Gütekriterien: Reliabilität: Rasch-Analysen ergaben eine innere Konsistenz von .91 bis .99 für die Langversion und von .76 für die Kurzversion. Die Retestreliabilität liegt in einem Zeitraum von zwei Wochen bei rtt = .89. Validität: Die Inhaltsvalidität kann durch den Konstruktionsprozess als gegeben betrachtet werden. Konvergente und diskriminante Validität wurde mit Hilfe des Osnabrücker Tests zur Zahlenbegriffsentwicklung (OTZ) und dem CFT 1 sowie zwei Untertests aus dem HAWIVA-III belegt. Die Konstruktvalidität konnte ferner durch Korrelationen zum TROG-D sowie zum BISC bestätigt werden. Normen: Als Normen liegen nach Alter differenzierte Prozentränge, T-Werte und T-Wert-Bänder vor, die an einer Stichprobe von N = 1095 Kindern im Alter von 48 bis 87 Monaten erhoben wurden. Die Normierung wurde zwischen 2009 und 2010 in unterschiedlichen Kindertagesstätten in Deutschland durchgeführt.publishedVersio
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
The utility of the South African Marko-D test with regard to identifying grade 1 English second language speakers with mathematics difficulties
Full text linkM.Ed. (Educational Psychology)Abstract: Over the last decade, many South African researchers have pointed out significant delays in children’s achievement in mathematics. Early identification and intervention can play a significant role in addressing learning delays and deficits. Among the various benefits of early identification is the possibility of more accurately identifying the level on the developmental trajectory at which a child is functioning and developing more precisely targeted teaching and intervention programmes. Tests are often useful in pinpointing where on the developmental trajectory a child is functioning. In this study, I examine the utility validity of the MARKO-D in identifying those learners most in need of an instructional boost, given that they are non-native speakers of English. Firstly, the typical developmental trajectory is elucidated using the conceptual theory underpinning the MARKO-D. In order to ultimately respond to the research question, the concept mathematical learning difficulties is defined. An argument is made that there are no diagnostic tests meeting the psychometric requirements to identify young children with mathematical learning difficulties. Lastly, validity is critically discussed, with a specific emphasis on defining utility validity within an item response framework. The theoretical model of utility validity feeds into the research design, which in turn feeds into the findings regarding utility validity of the MARKO-D. In the last chapter, the conclusion is drawn that the MARKO-D has fair utility in the identification of learners with mathematical learning difficulties. The implications of this finding for test development and use in South Africa are expounded. The limitations of the study and recommendations for further research are discussed
Erfassung von mathematischen Kompetenzen im Vorschulalter mit MARKO-D: Erprobung des Tests MARKO-D an einer Schweizer Stichprobe und Überprüfung des Instruments für Messwiederholungen
No full textIn dieser Studie wurde der Test MARKO-D (Mathematik- und Rechenkonzepte im Vorschulalter–Diagnose) mit einer Stichprobe von Kindern aus der deutschsprachigen Schweiz ( N = 555) im ersten und zweiten Kindergartenjahr erprobt und es wurde analysiert, ob sich die Altersnormen der deutschen Stichprobe auf die Schweiz übertragen lassen. Zudem wurde der Test mit einer Teilstichprobe ( n = 87) hinsichtlich Messinvarianz über die Zeit untersucht. Die Ergebnisse des eindimensionalen Rasch-Modells zeigen, dass das Instrument für die Schweiz geeignet ist. Die Testleistungen hängen jedoch vom Kindergartenbesuch ab. Für die Schweiz müssten deshalb nebst Altersnormen auch Normen pro Kindergartenhalbjahr verwendet werden. Die Analyse mittels Differential Item Functioning ergab, dass 17 von 55 Items von großer Messvarianz über die Zeit betroffen sind. Um das Instrument für Längsschnittuntersuchungen einsetzen zu können, müsste es weiterentwickelt werden
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
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
