A growing body of scholars, educators and policy makers has argued for reconceptualising schools as “learning organisations” in the last 25 years as. However, a lack of clarity on the concept has hindered its advance in theory and practice. This study responds to this problem by developing a schools as learning organisations scale that expands and clarifies the concept on several points. Drawing on survey data (nschool staff = 1,703) from Wales (UK), it examines the key characteristics of a school as a learning organisation through a principal component analysis and reliability analysis. The results showed that such a school is associated with eight dimensions: (a) a shared vision centred on the learning of all students, (b) partners contributing to school vision, (c) continuous learning opportunities, (d) team learning and collaboration, (e) a culture of enquiry, innovation and exploration, (f) systems for collecting and exchanging knowledge and learning, (g) learning with and from the external environment, and (h) modelling learning leadership. The resulting 65-item scale demonstrated good psychometric qualities. A reliable and valid schools as learning organisations scale can help enhance our understanding of the concept. The scale can also be used by school leaders, teachers and all others wanting to develop a thriving learning culture in their schools.  相似文献

This paper examines the relationship between cultural participation and regional development with reference to the European Capital of Culture in 2017. From the bidding stage, Aarhus 2017 claimed it put “participation” at the heart of its strategic plans, through consultation at roadshows and exhibitions. In addition, it aspired to use culture as a catalyst for development not only in the city of Aarhus but across the region of Central Denmark. This paper, therefore, examines how participation is defined and implemented to address regional development in the Aarhus 2017 process through textual analysis of documentation from Aarhus 2017 and delivery partners as well as over 20 interviews with managers and participants involved in a range of 2017 projects. The paper argues against the common prioritisation of urban and professional cultural institutions and makes the case for decentralised cultural provision that supports both amateurs and professionals through a regional networked structure.  相似文献

This investigation assessed the effect of dietary nitrate (NO3?) supplementation, in the form of beetroot juice (BR), on repeat-sprint performance in normoxia and normobaric hypoxia. 12 male team-sport athletes (age 22.3 ± 2.6 y, VO2peak 53.1 ± 8.7 mL.kg?1.min?1) completed three exercise trials involving a 10 min submaximal warm-up and 4 sets of cycling repeat-sprint efforts (RSE; 9 × 4 s) at sea level (CON), or at 3000 m simulated altitude following acute supplementation (140 mL) with BR (HYPBR; 13 mmol NO3?) or NO3depleted BR placebo (HYPPLA). Peak (PPO) and mean (MPO) power output, plus work decrement were recorded during the RSE task, while oxygen consumption (VO2) was measured during the warm-up. There were no significant differences observed between HYPBR and HYPPLA for PPO or MPO; however, work decrement was reduced in the first RSE set in HYPBR compared with HYPPLA. There was a moderate effect for VO2 to be lower following BR at the end of the 10 min warm-up (ES = 0.50 ± 0.51). Dietary NO3? may not improve repeat-sprint performance in hypoxia but may reduce VO2 during submaximal exercise. Therefore, BR supplementation may be more effective for performance improvement during predominantly aerobic exercise.  相似文献

Abstract

Carnosine was originally discovered in skeletal muscle, where it exists in larger amounts than in other tissues. The majority of research into the physiological roles of carnosine have been conducted on skeletal muscle. Given this and the potential for muscle carnosine content to be increased with supplementation, there is now a large body of research examining the ergogenic effects (or otherwise) of carnosine. More recent research, however, points towards a potential for carnosine to exert a wider range of physiological effects in other tissues, including the brain, heart, pancreas, kidney and cancer cells. Taken together, this is suggestive of a potential for carnosine to have therapeutic benefits in health and disease, although this is by no means without complication. Herein, we will provide a review of the current literature relating to the potential therapeutic effects of carnosine in health and disease.  相似文献

This study explored third-graders’ oral reading fluency (ORF) in easy text in relation to their third- and fourth-grade reading comprehension. It also examined the children’s performance on two different measures of text exposure, a self-report questionnaire and a title-recognition test. Although third-graders’ ORF related significantly to their reading comprehension, oral language comprehension accounted for most of the variance in reading comprehension, whereas single word reading speed accounted for most of the variance in ORF. Third-grade reading comprehension and ORF each predicted unique variance in children’s scores on a fourth-grade state-mandated reading comprehension assessment. Scores on the self-report questionnaire correlated significantly with third-grade ORF and fourth-grade reading; the self-report accounted for reliable variance in ORF even with all of the other reading ability variables entered first. Results are consistent with the viewpoint that text exposure affects reading fluency. They also demonstrate that ORF is a valuable predictor of middle-elementary children’s reading comprehension, even when the ORF measure employs very easy text in which children achieve near-perfect word accuracy.  相似文献

This paper reports the findings of an investigation aimed at gaining a clearer understanding of the nature of vocabulary difficulties associated with dyslexia and associated risk status. Three studies were conducted to examine preschoolers’ access and mastery of syntactic- and phonological-based processes believed to support word learning. Results are reported for 82 participants whose (reading) risk status was assessed from a composite of measures known to be related to reading development. As expected, risk status correlated positively with participants’ ability to recall the phonological form of novel nouns. No relationship was found between risk status and participants’ use of syntactic form-class cues in interpreting the noun class of novel names in isolation. However, the ability to use form-class cues was impaired for at-risk participants on a task that required them to learn both the phonological form and noun class. Findings are discussed in relation to the suggestion that limitations in processing resources such as working memory rather than in the availability of language structures may be at the root of the reported poor performance by at-risk children on vocabulary and other linguistic measures.

Many children fail to meet physical activity (PA) guidelines for health benefits. PA behaviours are complex and depend on numerous interrelated factors. The study aims to develop current understanding of how children from low Socio-economic environments within the UK use their surrounding built environments for PA by using advanced technology. The environment was assessed in 96 school children (7–9 years) using global positioning system (GPS) monitoring (Garmin Forerunner, 305). In a subsample of 46 children, the environment and PA were assessed using an integrated GPS and heart rate monitor. The percentage of time spent indoor, outdoor, in green and non-green environments along with time spent in moderate-to-vigorous PA (MVPA) in indoor and outdoor environments were assessed. A 2-by-2 repeated measures analysis of covariance, controlling for body mass index, BF%, assessed the environmental differences. The findings show that 42% of children from deprived wards of Coventry fail to meet PA guidelines, of which 43% was accumulated during school. Children engaged in more MVPA outdoor than indoor environments (P < 0.01) and a greater amount of time was spent in non-green environments (P < 0.01). Increased time outdoors was negatively associated with BF%. In conclusion, outdoor environments are important for health-enhancing PA and reducing fatness in deprived and ethnic children.  相似文献

Scotland, in common with many countries internationally, has been learning how to align ideas from research with policy and practice. This article considers what Scotland learned from large-scale evaluations of its Assessment is for Learning (AifL) programme and the extent to which this evidence was used to inform future learning within the national programme. More recently, the policy focus in Scotland has shifted to the creation of a new curriculum, Curriculum for Excellence, subsuming AifL. Merging curriculum and assessment innovations brought new challenges in the alignment of curriculum, pedagogy and assessment. Drawing on a Scottish Government-funded research project, Assessment at Transition, designed to identify and explore emerging gaps between practice in schools and local authorities and national curriculum and assessment policy aspirations, the article argues that assessment is learning and explores how formative approaches to evaluation at a national level might be used to prevent countries repeating past mistakes.  相似文献

We previously proposed that science capital (science-related forms of cultural and social capital) can be used as a theoretical lens for explaining the patterned nature of aspirations and educational participation among young people aged 11–16. Building on these findings, the present article investigates whether science capital is related to post-18 aspirations to pursue further STEM study and whether science capital can be extended to related disciplines including engineering, maths and technology. Specifically, we report on correlational analyses exploring the relationships between science, technology, engineering and maths attitudes and science capital. Drawing on data from a new survey of 7,013 17/18 year old English secondary school students, analyses showed that science capital, while strongly related to engineering and physical science future study aspirations, was not strongly related to the pursuit of either maths or technology postsecondary study. The findings also suggest that engineering and maths attitudes have a stronger relationship to science capital than attitudes relating to technology. We conclude with a discussion of the implications of these findings and propose that science capital might be more usefully applied to “SEM,” with links to technology fields and aspirations needing further exploration.  相似文献
