In this study, we assessed the validity and reliability of 5 and 10 Hz global positioning systems (GPS) for measuring instantaneous velocity during acceleration, deceleration, and constant velocity while straight-line running. Three participants performed 80 running trials while wearing two GPS units each (5 Hz, V2.0 and 10 Hz, V4.0; MinimaxX, Catapult Innovations, Scoresby, VIC, Australia). The criterion measure used to assess GPS validity was instantaneous velocity recorded using a tripod-mounted laser. Validity was established using the standard error of the estimate (± 90% confidence limits). Reliability was determined using typical error (± 90% confidence limits, expressed as coefficient of variation) and Pearson's correlation. The 10 Hz GPS devices were two to three times more accurate than the 5 Hz devices when compared with a criterion value for instantaneous velocity during tasks completed at a range of velocities (coefficient of variation 3.1-11.3%). Similarly, the 10 Hz GPS units were up to six-fold more reliable for measuring instantaneous velocity than the 5 Hz units (coefficient of variation 1.9-6.0%). Newer GPS may provide an acceptable tool for the measurement of constant velocity, acceleration, and deceleration during straight-line running and have sufficient sensitivity for detecting changes in performance in team sport. However, researchers must account for the inherent match-to-match variation reported when using these devices. 相似文献

The article focuses on the training of higher education language teachers from a quality enhancement perspective. After a brief discussion of the nature of quality in higher education, the article considers the implications which the expansion of language learning in higher education in Europe has for the teachers involve in designing and delivering language programmes. The main body of the article is then devoted to a discussion of the strategies and options in the field of the training of language teachers which emerged from reports on quality enhancement in higher education language studies prepared in 18 European countries. The reports were prepared within the framework of Thematic Network Project 2, organised by the European Language Council. The article concludes by highlighting the crucial role of teacher training in the ‘quality cycle’ with respect to both teaching and student learning.
L'article traite de la formation d'enseignants de langue travaillant dans l'enseignement supérieur d'une perspective axée sur l'amélioration de la qualité. Suite à une brève discussion de la notion de qualité dans l'enseignement supérieur, l'article examine les implications de l'expansion de l'apprentissage des langues dans l'enseignement supérieur en Europe pour les enseignants responsables de la conception et de la réalisation pédagogique de programmes de langue. La partie principale de l'article est alors consacrée à l'analyse des choix et stratégies dans le domaine de la formation d'enseignants de langues qui se sont dégagés de rapports sur l'amélioration de la qualité dans le domaine des langues dans l'enseignement supérieur dans 18 pays de l'Europe. Ces rapports furent préparés dans le cadre du Projet de Réseau Thématique 2, organisé par le Conseil Européen pour les Langues. En conclusion, l'article souligne le rôle crucial joué par la formation des enseignants par rapport à la qualité autant de l'enseignement que de l'apprentissage des langues par les étudiants.
El artículo trata de la formación de profesores de lengua que trabajan en la enseñanza superior, desde la perspectiva de la mejora de la calidad. Tras una breve discusión acerca de la noci?n de calidad en la enseñanza superior, el artículo examina las implicaciones de la expansión del aprendizaje de las lenguas en la enseñanza superior en Europa para los profesores responsables de la concepción y de la realización pedagógica de programas de lengua. La parte principal del artículo se consagra por tanto al análisis de las elecciones y estrategias en el campo de la formación de profesores de lenguas, tal como se desprenden de los informes sobre la mejora de la calidad en el campo de las lenguas en la enseñanza superior en 18 países de Europa. Estos informes fueron preparados en el marco del Proyecto de Red Temática 2, organizado por el Consejo Europeo para las Lenguas. En conclusión, el artículo subraya el papel crucial desempeñado por la formación de los profesores en la calidad tanto de la ensepanza como del aprendizaje de las lenguas por los estudiantes.
Der Artikel behandelt die Ausbildung von Sprachlehrkräften an Hochschulen aus der Sicht der Qualitätsverbesserung. Nach einer kurzen Erörterung der Spezifität der Qualität in der Hochschulbildung, befasst sich der Artikel mit den Konsequenzen des verstärkten Lehrens und Lernens von Sprachen an Hochschulen für die mit der Planung und Umsetzung von Sprachlehrprogrammen betrauten Lehrkräfte. Der Hauptteil des Artikels ist der Analyse von Strategien und Möglichkeiten im Bereich der Ausbildung von Sprachlehrkräften gewidmet, die aus 18 europäischen Länderberichten über Qualitätsverbesserung im Sprachenbereich an Hochschulen hervorgingen. Diese Berichte wurden innerhalb des vom Europäischen Sprachenrat organisierten Thematischen Netzwerkprojekts Sprachen II (TNP2) erstellt. Am Schluss des Artikels wird die entscheidende Rolle der Ausbildung der Sprachlehrkräfte für die Qualität des Lehrens und Lernens von Sprachen an Hochschulen hervorgehoben. 相似文献
In this article the author argues that the somewhat laissez‐faire attitude to curriculum reforms of the 1960s and 1970s led to their demise. The Bains Report (1972) marked recognition of the need for management techniques to promote corporate objectives successfully. A synthesis of the work of Schwab (1969), Everard (1982), Shipman (1983) and Dalin (1978) leads the author to suggest a simple ‘systems approach to management’ as a realistic framework for curriculum innovation. In conclusion, the author stresses that this model will not guarantee success, but provides a systematic approach for would‐be innovators. 相似文献
Scallywags is a community‐based, early intervention programme for young children (aged 3–7) with behavioural, emotional and social problems, which integrates work in the home and school with a parenting curriculum and direct work with children. A pre‐post intervention study across multi‐sites of 340 participants is reported. Using standardised measures, the study found statistically significant reductions in problems at home and school experienced by children who completed the programme, and in parental stress levels. Participation was found to be high and the project acceptable to parents, many of whom would be described as hard to reach. The rigorous evaluation of this real‐life service and its positive outcomes highlight the potential of such programmes to tackle the needs of these children and families, and help prevent longer‐term problems associated with early onset behavioural problems, including social exclusion, antisocial behaviour and educational failure. 相似文献
In democratic societies schools play a large role in helping students learn the values and skills necessary for adult participation in a free and open society. This article is a case study of a group of students who started a Gay-Straight Alliance (GSA) at a private American school in México City. The students' struggle to form and keep their GSA, in light of opposition from a school board member and conservative parents, is analyzed within a framework of critical pedagogy, the goal of which is the expansion of rights for oppressed groups through activist education. The author was co-advisor to the GSA and offers suggestions for others working with similar student groups. This student-led struggle illustrates lessons about democratic values, navigating bureaucracy, effecting social change, and working with others who have diverging opinions. 相似文献
Every so often, it is important to stand back and look at the whole context of our field of research and practice. In this article, I do this by shedding light on the ways we view the term vocations and the consequences of those views for education and training in community colleges and adult and community education providers of all kinds. I ask the question: What is Vocational Education and Training (VET) for? I ask this particular question because I know the answers are contested, staking out claims for territory in research and practice. The answer to the question that this article explores is that vocational education and training ''serve industry.'' Using Australia as a specific example of such a Western country, the article argues that the entrenched meanings for VET as serving industry have disenfranchised a large proportion of the population - especially small business and the rural sector. The article is pointing out that the resulting version of VET is gendered, classed, and urban-specific. This structurally entrenched position is then contrasted with data reported from empirical studies currently examining (among other things) the nature of vocations and work at a community level and the manner in which they are created there. The article raises three important implications: the convergence of Adult and Community Education with VET, learning pathways, and the effects on small business. 相似文献
