ABSTRACTDifferences and similarities between table tennis and other racquet sports exist, but are not well documented in the literature, in spite of the relevance for talent identification. In this study we aimed at identifying the key characteristics of table tennis in comparison with tennis and badminton based upon a survey in coaches. A total of 177 licensed coaches from all across the world and with diverse professional backgrounds completed a survey on anthropometric measures, physical performance, and motor coordination skills. On a scale from 1 to 10, coaches indicated to what extent a talent characteristic was important for their sport. MANOVA identified key differences as well as similarities between all three racquet sports and a subsequent discriminant analysis allocated coaches correctly for table tennis, tennis, and badminton 81.01%, 55.6%, and 71.4% respectively. Our results show that table tennis and other racquet sport coaches are well aware of differences between the racquet sports and also the importance and value of testing and assortment of skill components. These findings can assist coaches in future talent orientation and transfer in racquet sports. 相似文献

This article offers a case study of the evaluation of a redesigned and redeveloped laboratory-based cell biology course. The course was a compulsory element of the biology program, but the laboratory had become outdated and was inadequately equipped. With the support of a faculty-based teaching improvement project, the teaching team redesigned the course and re-equipped the laboratory, using a more learner-centered, constructivist approach. The focus of the article is on the project-supported evaluation of the redesign rather than the redesign per se. The evaluation involved aspects well beyond standard course assessments, including the gathering of self-reported data from the students concerning both the laboratory component and the technical skills associated with the course. The comparison of pre- and postdata gave valuable information to the teaching team on course design issues and skill acquisition. It is argued that the evaluation process was an effective use of the scarce resources of the teaching improvement project. 相似文献

Abstract The aim of this study was to determine whether rates of total fat and carbohydrate oxidation and endurance capacity during running conducted in the fasted state are influenced by the glycaemic index (GI) of high carbohydrate diets consumed over 5 days. Nine healthy males performed three treadmill runs to exhaustion at 65% of maximum oxygen uptake ([Vdot]O2max): after a habitual diet (control trial), after 5 days on a high carbohydrate/high glycaemic index diet, and after 5 days on a high carbohydrate/low glycaemic index diet in randomized counterbalanced order. No significant differences in rates of fat and carbohydrate oxidation, concentrations of plasma insulin, glucose, non-esterified fatty acids and glycerol, or time to exhaustion were observed between the high carbohydrate/high glycaemic index and high carbohydrate/low glycaemic index trials. Compared with the control trial, the concentration of plasma glycerol and rate of fat oxidation were lower (P < 0.05) and the rate of carbohydrate oxidation higher (P < 0.05) in both the high carbohydrate/high glycaemic index diet and high carbohydrate/low glycaemic index trials during the run to exhaustion. In conclusion, the extent by which a high carbohydrate diet consumed over 5 days reduces rate of fat oxidation during subsequent running exercise in the fasted state is not influenced by the glycaemic index of the diet. 相似文献

Two studies examine patterns of school readiness in children at school entry and how these patterns predict first-grade outcomes in a nationally representative sample of first-time kindergartners from the Early Childhood Longitudinal Study—Kindergarten Class of 1998–1999 (N = 17,219). In Study 1, cluster analyses revealed four profiles at kindergarten entry: comprehensive positive development (30%), social/emotional and health strengths (34%), social/emotional risk (13%), and health risk (22.5% of the sample). Study 2 results suggested that children with one of the two “risk” profiles were more likely to be from families with multiple socioeconomic disadvantages. In addition, all four profiles differentially predicted academic and social adjustment in early elementary school. Children with a risk profile performed the worst on all outcomes; children with a comprehensive positive development profile performed the best. The authors discuss the need for early identification of children who may be at risk for entering school with few school readiness strengths. 相似文献

Preservice teachers in a K–8 science methods course used guided video reflection to examine their interactions with children
during science teaching. This inquiry approach helped preservice teachers identify and respond to gaps between their beliefs
and intentions about teaching all children and their enactment of those beliefs. The experience of teaching a science lesson
and then viewing it multiple times through a critical framework provided an opportunity for preservice teachers to recognize
hidden assumptions, unexamined behaviors, and the unintentional meanings they may have conveyed to children. This encouraged
them to think more critically about their roles as teachers in creating spaces where all children have access to quality science
learning experiences.

Interest Assessment and the Content Area Literacy Environment: Challenges for Research and Practice 总被引:3,自引:0,他引:3
Through our exploration of the assessment of interest, we highlight 5 issues that emerge in the effort to assess interest in content area literacy environments. First, we compare how interest is defined and generally how it has been assessed. Second, we focus more specifically on the assessment of text-based interest, and consider its assessment in less explored realms of the content area classroom that include hypertext and discussions. Third, we investigate how interest develops as students progress through their educational careers and how it is maintained over time. Fourth, we explore how assessing interest involves examining other student factors that are closely related to interest such as knowledge, importance, and strategic processing. Finally, we offer thoughts regarding directions educators can take in assessing interest within the complex literacy environment of today's content area classroom. 相似文献

Games play a significant role in childhood, fuelling hours of engagement and social interaction, and probably much learning as well. Board games, card games and outdoor games (such as Tag) first come to mind, but more recently, games have also gone digital. In this piece, we offer a new perspective by placing games within the established construct of ‘playful learning’. We review key elements of playful learning and the two subtypes: free play and guided play. We suggest that games promote learning in ways similar to other playful learning situations. Games involve fun, a sense of curiosity and an inhibition of reality, in active, engaging, meaningful and socially interactive contexts. We argue that games therefore belong alongside free play and guided play to form a trio of playful learning experiences. This perspective adds to a growing understanding of the role of games in supporting children’s learning and development. 相似文献

Keyword: Education Economics and Quality of Schooling. With reference to an earlier keyword article from the same author, this contribution looks at recent developments in education economics. The focus is a critical review of the field‘s contribution to research on the necessary conditions for high quality schooling. Of particular interest at the moment are the institutional framework conditions in a school system, which set incentives for performance. These are judged to be better than resource-based strategies of quality assurance. The empirical basis is provided by estimates of production functions using data from international school performance studies. This article will point out the limited validity of evidence gained through these studies and the – in sum – contradictory empirical findings. For this reason, political recommendations on the basis of this approach should be more reserved. 相似文献

One aspect of the mediatization of politics is the idea that political actors adapt to the communication logic of news media to gain, for example, news media attention. Currently, this process may be influenced by the diffusion of the internet as a political communication channel, especially because online communication provides a new opportunity for political actors to communicate directly with citizens. Thus far, the adaptation to media logic by political parties has mainly been examined in the context of election campaigns. In order to transfer these findings to regular political communication, this study compares the use of media logic in the mass media and in direct political communication channels online and offline about the United Nations Climate Change Conferences 2011 and 2012. A quantitative content analysis of the conference protocols (input) and the presentation of the conference results in the seven most frequently used German offline news outlets (print and TV) and their online counterparts, as well as political offline and online communication channels like parliamentary speeches and websites of the six parties represented in the German parliament (output), was conducted. Results show that in the context of regular political communication, political actors seem to follow media logic to a lesser extent than in the context of election campaigns. Thus far, the influence of online communication on the mediatization of politics seems to be rather marginal. The causes and consequences of these findings are discussed. 相似文献
