“I thought we were supposed to learn how to become better coaches”: developing coach education through action research     

Christian Røj Voldby  Rasmus Klein-Døssing 《Educational Action Research》2020,28(3):534-553

ABSTRACT

Youth coaches play a crucial role in the development of young athletes and their physical, psychological and social well-being. Therefore, it is important to foster and develop youth coaches’ ability to govern and act effectively in their coaching practices. Sports organisations facilitate the development of youth coaches through formal coach education. However, research has shown this to be with limited effect. The purpose of this action research study was to involve youth coaches in developing a new and more effective coach education practice.

The coaches developed their practices through both dialogue and reflection with each other. A shift in the mindset of the coaches resulted in a more reflective and analytical approach in their way of thinking and talking about their practices. The most effective tools for improving the coach educational practice was the active management of the relations between the participating coaches and assisting the coaches’ reflection and dialogue through the use of scaffolding. In order to engage coaches in the educational practice, alignment between coaches’ expectations and both course content and form was crucial. These findings provide further insight into how coaches can develop their practices and how sports organisations can develop more effective coach education practices.  相似文献

Communicative Functions of the Museum Lobby     

Christian Hviid Mortensen  Maja Rudloff  Vitus Vestergaard 《Curator: The Museum Journal》2014,57(3):329-346

In a time with a heightened focus on how museum architecture and exhibition design shapes the museum visit, the entrance space of museums, the museum lobby, is remarkably absent from the museum literature and research. Still, the museum lobby is the first encounter visitors have with the museum and the last impression that they take home and share with others. This article analyzes museum lobbies as communication spaces in order to identify the different functions afforded by such spaces. In an explorative study of five Danish museum lobbies, we offer a preliminary categorization of these functions that can be compared at a general level. Concrete examples will be used to discuss general issues such as the adaptive borders of lobby spaces and the counteracting effects of design. We suggest that the preliminary categorization provided here can form a foundation for further studies resulting in practical suggestions for design improvements.  相似文献   

Ranking economists on the basis of many indicators: An alternative approach using RePEc data     

Christian Seiler  Klaus Wohlrabe 《Journal of Informetrics》2012,6(3):389-402

In economics the Research Papers in Economics (RePEc) network has become an essential source for the gathering and the spread of both existing and new economic research. Furthermore, it is currently the largest bibliometric database in economic sciences containing 33 different indicators for more than 30,000 economists. Based on this bibliographic information RePEc calculates well-known rankings for authors and academic institutions. We provide some cautionary remarks concerning the interpretation of some provided bibliometric measures in RePEc. Moreover, we show how individual and aggregated rankings can be biased due to the employed ranking methodology. In order to select key indicators describing and assessing research performance of scientist, we propose to apply principal component analysis in this data-rich environment. This approach allows us to assign weights to each indicator prior to aggregation. We illustrate the approach by providing a new overall ranking of economists based on RePEc data.  相似文献

Tracing the links between science and technology: An exploratory analysis of scientists’ and inventors’ networks   总被引：1，自引：0，他引：1  

Stefano Breschi  Christian Catalini 《Research Policy》2010,39(1):14-26

The paper provides an exploratory analysis of the research networks linking scientists working in an open science environment, and researchers involved in the private technology domain. The study combines data on scientific co-authorship with data on patent co-invention, at the level of individual researchers, for three science-intensive technology fields, i.e. lasers, semiconductors and biotechnology, in order to assess the extent of the overlap between the two communities and to identify the role of key individuals in the process of knowledge transfer. Our findings reveal that the extent of the connectedness among scientists and inventors is rather large, and that particular individuals, i.e. authors-inventors, who act as gatekeepers and bridge the boundaries between the two domains, are fundamental to ensuring this connectivity. These individuals tend to occupy prominent positions in the scientific and the technological networks. However, our results also show maintaining a very central position in the scientific network may come at the expense of being able to fill a similarly central position in a technological network (and vice versa). Finally, preliminary analysis of the institutional origins of authors-inventors shows that one characteristic, distinctive of Europe compared to the United States, is associated with the relatively lower involvement of corporate scientists at the intersection between the two worlds of science and technology.  相似文献   

Implementation Factors and Their Influence on Student Mathematics Outcomes     

Tasia Brafford  Beth Harn  Ben Clarke  Christian T. Doabler  Derek Kosty  Kathleen Scalise 《Learning disabilities research & practice》2023,38(1):5-14

Assessing implementation allows for a better understanding of an intervention's effects and the mechanisms that influence its impact. Two main areas of implementation are (a) the quality with which an intervention is delivered and (b) instructors’ adherence to the programmed intervention. The current study used data from a kindergarten mathematics intervention program to (a) examine if and how treatment adherence was associated with implementation quality and (b) explore implementation measures’ relation to student mathematics outcomes. Results indicated high implementation scores across time for both adherence and quality. Neither treatment adherence nor implementation quality was found to relate to a general outcome measure of student mathematics achievement; however, both were similarly related to the curricular-aligned measure.  相似文献   

Does having vulnerable friends help vulnerable youth? The co-evolution of friendships,victimization, and depressive symptoms in Chinese adolescents' social networks

This study examined whether having vulnerable friends helps or hurts victimized and depressed (i.e., vulnerable) adolescents and whether this depends on classroom supportive norms. Students (n = 1461, 46.7% girls, 93.4% Han nationality) were surveyed four times from seventh and eighth grade (M_age = 13 years) in 2015 and 2016 in Central China. Longitudinal social network analyses indicated that having vulnerable friends can both hurt and help vulnerable adolescents. Depressed adolescents with depressed friends increased in victimization over time. Victimized adolescents with victimized friends increased in victimization but decreased in depressive symptoms. These processes were most likely in classrooms with high supportive norms. Having friends and a supportive classroom may hurt vulnerable adolescents' social position but help victims' emotional development.  相似文献
