Phonological awareness in kindergarten: a field study in Luxembourgish schools     

Sylvie Bodé  Alain Content 《European Journal of Psychology of Education - EJPE》2011,26(1):109-128

The purpose of the present study was to assess the effectiveness of a phonological awareness training program in the specific context of the Luxembourgish educational system. The intervention was run by the kindergarten teachers in their classes with minimal external supervision. Forty-one classes of the area around Luxembourg City participated in the study. One hundred and fifty children from 20 kindergarten classes were part of the training group and 157 children from 21 classes formed the control group. At the end of kindergarten, clear training effects were observed for all phonological awareness tasks, except for the highly demanding phoneme deletion task. After 6 months of reading and writing instruction in first grade, no training effects were found in a pseudoword spelling task for the entire training group. Only at-risk children, which had the lowest performance on preschool phonological awareness measures, showed significant training effects. We conclude that early phonological awareness training may be profitably incorporated in kindergarten classroom activities, particularly for at-risk pupils, even when the language characteristics and teaching methods already concur in facilitating the understanding of the alphabetic principle.  相似文献

The rating of perceived exertion predicts intermittent vertical jump demand and performance     

Pereira G  Correia R  Ugrinowitsch C  Nakamura F  Rodacki A  Fowler N  Kokubun E 《Journal of sports sciences》2011,29(9):927-932

The aims of this study were (a) to assess the ability of the rating of perceived exertion (RPE) to predict performance (i.e. number of vertical jumps performed to a fixed jump height) of an intermittent vertical jump exercise, and (b) to determine the ability of RPE to describe the physiological demand of such exercise. Eight healthy men performed intermittent vertical jumps with rest periods of 4, 5, and 6 s until fatigue. Heart rate and RPE were recorded every five jumps throughout the sessions. The number of vertical jumps performed was also recorded. Random coefficient growth curve analysis identified relationships between the number of vertical jumps and both RPE and heart rate for which there were similar slopes. In addition, there were no differences between individual slopes and the mean slope for either RPE or heart rate. Moreover, RPE and number of jumps were highly correlated throughout all sessions (r = 0.97-0.99; P < 0.001), as were RPE and heart rate (r = 0.93-0.97; P < 0.001). The findings suggest that RPE can both predict the performance of intermittent vertical jump exercise and describe the physiological demands of such exercise.  相似文献   

Effects of cold water immersion on the recovery of physical performance and muscle damage following a one-off soccer match     

Ascensão A  Leite M  Rebelo AN  Magalhäes S  Magalhäes J 《Journal of sports sciences》2011,29(3):217-225

The aim of this study was to assess the effects of a single session of cold or thermoneutral water immersion after a one-off match on muscular dysfunction and damage in soccer players. Twenty-male soccer players completed one match and were randomly divided into cryotherapy (10 min cold water immersion, 10°C, n = 10) and thermoneutral (10 min thermoneutral water immersion, 35°C, n = 10) groups. Muscle damage (creatine kinase, myoglobin), inflammation (C-reactive protein), neuromuscular function (jump and sprint abilities and maximal isometric quadriceps strength), and delayed-onset muscle soreness were evaluated before, within 30 min of the end, and 24 and 48 h after the match. After the match, the players in both groups showed increased plasma creatine kinase activity (30 min, 24 h, 48 h), myoglobin (30 min) and C-reactive protein (30 min, 24 h) concentrations. Peak jump ability and maximal strength were decreased and delayed-onset muscle soreness increased in both groups. However, differential alterations were observed between thermoneutral water and cold water immersion groups in creatine kinase (30 min, 24 h, 48 h), myoglobin (30 min), C-reactive protein (30 min, 24 h, 48 h), quadriceps strength (24 h), and quadriceps (24 h), calf (24 h) and adductor (30 min) delayed-onset muscle soreness. The results suggest that cold water immersion immediately after a one-off soccer match reduces muscle damage and discomfort, possibly contributing to a faster recovery of neuromuscular function.  相似文献   

The impact of different types of physical activity on total and regional bone mineral density in young Brazilian athletes     

Silva CC  Goldberg TB  Teixeira AS  Dalmas JC 《Journal of sports sciences》2011,29(3):227-234

Bone turnover is affected by exercise throughout the lifespan, especially during childhood and adolescence. The objective of this study was to investigate the impact of different sports on total and regional bone mineral density in male Brazilian adolescent athletes. Forty-six adolescents aged 10-18 years participated in the study: 12 swimmers, 10 tennis players, 10 soccer players, and 14 sedentary individuals. The athletes had engaged in physical activities for more than 10 h per week in the previous 6 months. Bone mineral density of the lumbar spine (L1-L4), left proximal femur region, and whole body was evaluated by dual-energy X-ray absorptiometry. Results showed higher mean values in the proximal femur region of tennis and soccer players (1.02 ± 0.18; 0.96 ± 0.16, respectively) than swimmers and controls (0.91 ± 0.14 and 0.87 ± 0.06, respectively) (P < 0.05). In relation to the impact of sporting activities based on bone age determination, we observed significant differences in bone mineral density at all evaluated sites at the end of puberty (16-18 years) compared with 10-12 years, with increases of 78% in the lumbar spine, 47% in the proximal femur, and 38% in the whole body.  相似文献

常识的概念已经成为一种意识形态,在当代社会构建霸权主义、并将霸权主义作为道德与智力领导力的过程中起着重要作用。尽管在事实上新自由主义作为一种经济发展模式已经彻底失败,与新自由主义相关的文化政治仍然盛行于世,并在塑造现代政府和教育角色的理念中变成了新的常识。新自由主义全球化是全球化中最突出的模式,以市场相对于政府的主导地位和放松管制的治理模式为前提,在"学术资本主义"背景下深深地影响了高校。由此带来的改革通常以促进国际竞争力为合理借口,也被称为"竞争型改革"。市场力量日益渗透到高等教育领域,围绕学术资本主义"游戏"展开的大学治理模式的重构,均显示了新自由主义对高校影响的四个主要方面,即效率与问责制、认证与普及化、国际竞争力、私有化。通过引入以管理主义治理院校的新型模式,高校深化并扩大了自身的危机。虽然高校采纳并实施了这些改革措施,但是在不同领域,在自上而下地通过政策和重心调整强制改革时,全球化面临着越来越大的阻力。在许多情况下,新自由主义改革通过收取较高学费与减少政府对院校和个人的支持,限制了一些阶级和种族接受高等教育的机会。 更多还原  相似文献
