Use of social web technologies by international and domestic undergraduate students: implications for internationalising learning and teaching in Australian universities     

Kathleen Gray  Shanton Chang  Gregor Kennedy 《Technology, Pedagogy and Education》2013,22(1):31-46

Much research into the use of online information and communication technologies for the internationalisation of learning and teaching has focused on established web technologies. This paper considers the possible internationalisation implications of existing uses of social software, also known as Web 2.0 technologies, which are now widely available inside and outside of formal education settings. The paper reports on two studies: the first, conducted at a large Australian university, investigated differences between international and domestic undergraduate students’ (n = 1973) use of web‐based technologies and tools; the second investigation reports on interviews with eight Australian and eight Singaporean university students about their use and perceptions of blogs and blogging. The findings from two studies provide new evidence of both cultural similarities and cultural differences in aspects of young university students’ use of social software for communication and content creation. Discussion and conclusions draw out factors to be considered in planning to implement new uses of social software among culturally and linguistically diverse students of the Net Generation, in Australia and more generally.  相似文献   

The danger of inadequate conceptualisation in PISA for education policy     

Slavko Gaber  Gregor Cankar  Ljubica Marjanovič Umek  Veronika Tašner 《Compare》2012,42(4):647-663

Due to the broad acceptance of the Programme for International Student Assessment (PISA) and other comparative studies as instruments of policymaking, its accuracy is essential. This article attempts to demonstrate omissions in the conceptualisation, and consequently in calculation and interpretation, of one of the central points of PISA 2006 and 2009. The authors point to the danger of such omissions for possible evidence-based education policymaking. With regard to the reproduction of social inequalities through education, we focus on variance in student performance between schools and within schools on the science scale (PISA 2006) and in the mother tongue (PISA 2009). The thesis of the PISA study is that there are countries (Finland, Iceland and Norway) where between only 14 and 29% of the average OECD variance (33%) is attributed to between-school variance – which is good – and there are countries (Germany, Bulgaria, Austria, Hungary, Belgium, Slovenia, the Netherlands, etc.), where the variance between schools is at least ‘one-and-a-half times that of the OECD’ – which is bad. For Slovenia, we demonstrate a significantly different share of variance explained by between-school variance of the same or similar cohort if we move the point of research by only nine months. Our main argument is that such a difference in the share of variance is not the result of a substantial change in the results (grooving difference in the performance) but the result of formal organisational change – the transition of the cohort to upper secondary education. The difference in calculations also radically changes policy implications, which is crucial. While PISA data suggest the necessity of policy measures to reduce between-school variance, our calculations suggest the need for reconsideration of policy measures aimed at the reduction of within-school variance, gender differences, and differences in performance between native and immigrant students.  相似文献

A biomechanical analysis of common lunge tasks in badminton     

Gregor Kuntze  Neil Mansfield  William Sellers 《Journal of sports sciences》2013,31(2):183-191

Abstract

The lunge is regularly used in badminton and is recognized for the high physical demands it places on the lower limbs. Despite its common occurrence, little information is available on the biomechanics of lunging in the singles game. A video-based pilot study confirmed the relatively high frequency of lunging, ～15% of all movements, in competitive singles games. The biomechanics and performance characteristics of three badminton-specific lunge tasks (kick, step-in, and hop lunge) were investigated in the laboratory with nine experienced male badminton players. Ground reaction forces and kinematic data were collected and lower limb joint kinetics calculated using an inverse dynamics approach. The step-in lunge was characterized by significantly lower mean horizontal reaction force at drive-off and lower mean peak hip joint power than the kick lunge. The hop lunge resulted in significantly larger mean reaction forces during loading and drive-off phases, as well as significantly larger mean peak ankle joint moments and knee and ankle joint powers than the kick or step-in lunges. These findings indicate that, within the setting of this investigation, the step-in lunge may be beneficial for reducing the muscular demands of lunge recovery and that the hop lunge allows for higher positive power output, thereby presenting an efficient lunging method.  相似文献   

AEG-Telefunken TR 440: Struktur und Technologie     

Eike Jessen  Dieter Michel und Heinz Voigt 《Informatik - Forschung und Entwicklung》2008,22(4):227-235

Zusammenfassung  Der Telefunkenrechner TR 440 war bei seiner Fertigstellung 1970 die schnellste bisher in Europa entwickelte und produzierte Maschine. 46 Maschinen wurden in Wissenschaftseinrichtungen, bei Beh?rden und in der Industrie installiert. Der TR 440 folgte dem 1962 fertig gestellten TR 4, der auf demselben Markt durch Leistungsf?higkeit und sein innovatives Compilerkonzept eine wichtige Stellung erobert hatte. Der TR 440 wurde als Maschine für den Teilnehmerbetrieb entwickelt. Die Maschine war einer der ersten gro?en Rechner mit integrierten Schaltungen. Sie verfügte über Seitenadressierung und ein ausgefeiltes System von privilegierten Funktionen. Die Leistung des Prozessors betrug knapp 1 Mips, die Hauptspeicherkapazit?t 1.5 MB. Ausgangspunkt, Struktur und Technologie werden aus heutiger Sicht beschrieben. Ein Nachfolgeprodukt, TR 550, wurde konzipiert, aber nicht mehr entwickelt. Die Wertsch?tzung des TR 440 bei den Nutzern ging wesentlich auf die Systemsoftware zurück, die Gegenstand eines anderen Beitrages ist [6].

The Telefunken TR 440 Computer was, at its deployment in 1970, the fastest machine developed and manufactured so far in Europe. 46 of them were installed in scientific institutions, agencies, and industry. The TR 440 was the successor of the TR 4 of 1962, which on the same market had gained an important position by its performance and its innovative compiler concept. TR 440 was designed for timesharing operation. The machine was one of the first large scale computers to use integrated circuits. It had page addressing and a refined system of privileged functions. The instruction rate approached 1 Mips, the main memory had a capacity of 1.5 MB. Point of departure, structure and technology are described from the point of view of today. A follow-on product, TR 550, was conceived but not developed. The appreciation TR 440 gained among its users was primarily due to its system software, which is described in a further paper [6]. TR 440 structure and technology is also subject of a paper submitted to the IEEE Annals of the History of Computing.

Zusammenfassung. In der Arbeit werden klausale Spezifikationen zur Beschreibung von Programmen auf der Ebene des funktionalen Entwurfs betrachtet. Die Axiome solch einer Spezifikation bestehen aus positiv/negativ bedingten Gleichungen, die neue Operatoren über einer fest eingebauten Algebra definieren. Wir definieren als Semantik von eine Algebra , die initial in der Klasse aller Modelle ist. Es wird ein Inferenzsystem angegeben, mit dem man die Gültigkeit von positiv/negativ bedingten Gleichungen in beweisen kann. Dieses Inferenzsystem erlaubt es auch, die Gültigkeit von Behauptungen zu widerlegen. Eingegangen am 19. Juli 1994 / Angenommen am 7. November 1995  相似文献

Integration von Techniken der Softwarespezifkation für ingenieurwissenschaftliche Anwendungen     

Hartmut Ehrig und Martin Gro?e-Rhode 《Informatik - Forschung und Entwicklung》2001,16(2):110-117

Zusammenfassung. Der Softwareanteil in technischen Systemen bekommt einen immer h?heren Stellenwert. Für einen durchg?ngigen und wartbaren Entwurf der Software sind Spezifikationstechniken erforderlich, die von ingenieurwissenschaftlichen Ablaufbeschreibungen bis zu (objektorientierten) Softwaremodellen reichen. Wesentlich ist dabei, solche Techniken zu integrieren, um zu einem durchg?ngigen Systemmodell zu gelangen. Dies ist Gegenstand des DFG-Schwerpunktprogramms „Integration von Techniken der Softwarespezifikation für ingenieurwissenschaftliche An- wendungen”, in dem Ingenieure und Informatiker in vierzehn Forschungsprojekten gemeinsam an der Entwicklung integrierter Methoden zur Softwarespezifkation vornehmlich in den Bereichen Produktionsautomatisierung und Verkehrsleittechnik arbeiten. In diesem Artikel geben wir einen überblick über die Ergebnisse der ersten zwei Jahre des Schwerpunktprogramms und dessen Ziele für den weiteren Verlauf von vier Jahren.   相似文献
