Purpose: In sports games, coaches often use tactic boards to present tactical instructions during time-outs (e.g., 20 s to 60 s in basketball). Instructions should be presented in a way that enables fast and errorless information processing for the players. The aim of this study was to test the effect of different orientations of visual tactical displays on observation time and execution performance. High affordances in visual-spatial transformation (e.g., mental rotation processes) might impede information processing and might decrease execution performance with regard to the instructed playing patterns. Method: In a within-subjects design with 1 factor, 10 novice students were instructed with visual tactical instructions of basketball playing patterns with different orientations either showing the playing pattern with low spatial disparity to the players’ on-court perspective (basket on top) or upside down (basket on bottom). Results: The self-chosen time for watching the pattern before execution was significantly shorter and spatial accuracy in pattern execution was significantly higher when the instructional perspective and the real perspective on the basketball court had a congruent orientation. Conclusion: The effects might be explained by interfering mental rotation processes that are necessary to transform the instructional perspective into the players’ actual perspective while standing on the court or imagining themselves standing on the court. According to these results, coaches should align their tactic boards to their players’ on-court viewing perspective. 相似文献

Education has continuously been regarded as a vital tool in Norwegian policymakers' immigrant integration agendas. This study analyzes semantic structures substantiating the policy language of historical Norwegian immigrant education policies from their inception in 1973 until today (2013). The analysis is framed by Kronenfeld's linguistic anthropological theory “semantic extensionism”. Four distinct semantic models are identified through the historical period. Each model comprises specific overall policy programs, education system characters, teaching methods, and parameters for equality output evaluations. We show how the core semantic structures of each model, and the changes between them, derive from three interacting factor domains: (1) semantic inclusion and contrast relations, (2) pragmatic characteristics of practice fields, and (3) broader welfare state policy histories. 相似文献

The relative age effect (RAE) refers to that children born early in their year of birth show higher performance compared to children born late in the same cohort. The present study evaluated whether RAE exists within non-competitive physical education (PE) attainments, change in RAE magnitude with age, and possible gender differences. The results show a drop in PE attainment and a difference in number of high and low marks between the first and second half-year. Of the pupils who attained the highest mark, 73% were born in the first 6 months. In lower-secondary school, RAEs were larger in girls compared with boys. A possible explanation for the results is that the PE-teachers might be inspired by product-oriented criteria. 相似文献

The Canadian federal government, anxious to stimulate innovation, announced recently a policy objective for the economy: the attainment of industrial research expenditures reaching 1.5 percent of the gross national product. The proposed substantial increase over the current level is rationalized by comparison with economy-wide research intensities (GERD/GNP) in other OECD countries.This paper questions the economic validity and policy relevance of international aggregate comparisons. It argues that inter-country comparisons should take place at individual industry levels where technologies are similar and proposes a methodology for formulating R&D spending targets of this kind. The procedure is to estimate a model of the determinants of R&D intensity with data from several “criterion countries” and employ the results to “predict” a specific industry's research intensity in another country.In this paper such a model is formulated for the pharmaceutical industry of seven OECD countries. Plausible parameter estimates are derived and used to “forecast” the research intensity of the Canadian pharmaceutical industry. It is found that given the predominance of foreign ownership, the nature of patent protection and the level of other relevant variables in Canada, the performance of this sector is much above the OECD-derived standard; this Canadian industry presumably does not require governmental attention to its R&D activities. 相似文献

The purpose of this paper is to present a participatory multimedia learning model that can be used in designing multimedia
learning environments that support an active learning process and creative participation. Participatory multimedia learning
can be defined as learning with systems that enable learners to produce part of the learning materials themselves. The aim
of the model is to represent the human information processing system and to support the transformation of free cognitive resources
into a germane cognitive load needed for knowledge construction. The paper also elaborates on the results of an empirical
study examining the effectiveness of student-generated illustrations. Finnish elementary school students (N = 187) learned about the human immune system by interacting with multimedia learning materials. Students performed better
on a retention test when they generated their own illustrations by drawing and when explanations were presented as animations,
compared to students who received only textual material or generated illustrations from images offered. 相似文献

ABSTRACT Despite the importance of technique and tactics for athlete performance, there has been surprisingly little research on the value of these skills in talent identification and development. This study investigated the relationship between coaches’ early notational analyses of female youth handball players and the long-term success of these athletes. Participants included sixty-eight female handball players involved in a talent selection camp in Germany when they were between 12 and 14 years of age (mean = 14.42, SD = 0.42). All subsequently ended up as non-, semi- or professional adult players. During the initial selection camp, participants were evaluated on a range of quantitative and qualitative measures of technical and tactical skill. Results indicated significant differences between the groups, but only for the number of actions taken, not for the quality of those actions. While this seems counterintuitive, it may reflect the likelihood that more skilled and/or talented players take more actions. Further work is necessary to explore the validity and implications of these findings. 相似文献
