ABSTRACT

Despite UNESCO’s Learning Cities agenda, which argues for the mobilisation of resources to promote education across all sectors and environments, there is little evaluative research on Learning City engagement which is both naturalistic and empirically rigorous. The research on informal adult learning in urban contexts is particularly sparse. This paper provides a case study of informal learning and lifewide literacies amongst Glaswegian adults using three distinct approaches to data collection: a household survey capturing rich data on learning attitudes, behaviours, and literacies; GPS trails that track mobility around the city; and the capture of naturally occurring social media. The work operationalises Learning City indicators, and explores domains beyond education, some of which have not previously been considered in surveys of adult learning, for example, physical mobilities and transportation patterns. We use theoretical concepts of social identity and capital to situate inclusion within explanatory frameworks of marginalisation in less tangible domains of informal learning using multi-stranded data. A triangulated analysis of city-wide participation in lifewide learning reveals a demographic picture of groups marginalised from learning opportunities and practices. We conclude with a call for new approaches to exploring learning participation which offer novel methods to evidence informal learning and lifewide literacies.  相似文献

The purpose of this study was to examine the reliability and validity of scores from six early literacy probes developed for use with preschool‐age children. The literacy probes were administered to 84 preschoolers at three time points over a 6‐month period. Also, a criterion measure of early literacy skills was administered to a subset of students. Results indicated that the probes demonstrate adequate reliability for screening decisions, moderate to strong concurrent relationships with a criterion measure, and developmentally appropriate changes in children's early literacy skills over time. These results add to the growing body of evidence supporting the technical adequacy of general outcome measurement for use in monitoring the progress of preschoolers' academic skill development. © 2009 Wiley Periodicals, Inc.  相似文献

To further the understanding of the effects of early experiences, 9-month-old infants were observed during a frustration task. The analytical sample was composed of 348 linked triads of participants (adoptive parents, adopted child, and birth parent[s]) from a prospective adoption study. It was hypothesized that genetic risk for externalizing problems and affect dysregulation in the adoptive parents would independently and interactively predict a known precursor to externalizing problems: heightened infant attention to frustrating events. Results supported the moderation hypotheses involving adoptive mother affect dysregulation: Infants at genetic risk showed heightened attention to frustrating events only when the adoptive mother had higher levels of anxious and depressive symptoms. The Genotype × Environment interaction pattern held when substance use during pregnancy was considered.  相似文献

Tibial acceleration is a surrogate measure for impact loading and lower limb fatigue injury in runners. Triaxial accelerometers may offer reliable and practical measurement of resultant peak tibial acceleration (PTA). With such potential in mind, this study examined variability and measurement reliability of tibial acceleration in 14 runners at baseline at one week, and eight of the runners again at six months. Triaxial accelerometers were attached to the distal tibiae of runners before they ran on a treadmill for two minutes each, at speeds of 2.7, 3.0, 3.3 and 3.7 m/s in standardised shoes. Resultant PTAs were calculated for each speed and session. Reliability outcomes were presented as percentage change and effect sizes. Variability outcomes included intraclass correlation coefficients and the typical error of the measurement. Smallest worthwhile change and performance/noise ratio were also calculated. While runners demonstrated marginally lower reliability and higher variability over six months, compared to one week, in all cases the measures of reliability and variability were of ‘good’ to ‘moderate’ reliability, and ‘small’ to ‘moderate’ variability using magnitude-based inferences. We can be confident that resultant PTA can be used with runners to assess and monitor their impacts throughout a six-month intervention.  相似文献

This review poses three key issues that will progress our understanding of the sport expertise literature and its translational scientific impact. Primarily relying on research conducted in interceptive sport tasks, and to a lesser extent team sports, we review the perceptual-cognitive skills of sports experts and explore the challenge of designing a sufficiently representative task to examine expertise. We focus on the methodological challenges presented by the reciprocal relationship between players’ action capabilities and their perceptual-cognitive skill. Second, we consider the need for a paradigm shift in the experimental approach used when examining the development of sport expertise. In short, a shift from traditional expert-novice designs to more prospective longitudinal designs that cross-sectionally track the development of expertise is discussed. The final issue considers how the volume of in situ data now collected provides a rich source of information that sport expertise researchers have only begun to consider and integrate with more traditional sport psychology research. We demonstrate how statistical approaches that have described the likely trajectories of expert performers on their journey toward expertise coupled with more traditional qualitative experimental approaches can provide useful insights into the development of psychological performance skills and more broadly sport expertise.  相似文献

Over the past decade U.S. policymakers, practitioners, and researchers have sought to examine if changing teacher evaluation policies and systems have resulted in changes in identifying quality teachers and/or increased student achievement. This research generally shows most states have experienced little change in how teachers are rated. Researchers are now exploring why, in many cases, teacher evaluation reforms have failed to produce the desired systematic changes of better identifying quality teachers and better distinguishing teacher performance. Embedded within this line of inquiry is how principals (and other evaluators) are trained to use new teacher evaluation systems. This comparative case study observed six principals (three charter school principals and three traditional public school principals) in the U.S. state of Michigan as they learned and enacted a new teacher evaluation system. Additionally, all principals were interviewed three times throughout the school year, in an effort to examine how their initial teacher evaluation training impacted their evaluation of teachers. The research questions that guided this work were: (1) how are principals initially trained when their school adopts a new teacher evaluation system?; (2) in what ways does the training received by charter school principals compare to that of traditional public school principals?; and (3) how does initial training impact how principals evaluate teachers? Results indicate principals are trained to navigate the logistics of new teacher evaluation systems, but are not trained to evaluate teacher performance. Implications for policy and practice are discussed.  相似文献

This paper contains a consideration of the notion of genius and its significance to the discussion of the aesthetics of sport. We argue that genius can make a positive aesthetic contribution in both art and sport, just as some have argued that the moral content of a work of art can affect its aesthetic value. A genius is an exceptional innovator of successful strategies, where such originality adds aesthetic value. We argue that an original painting can have greater aesthetic value than an exact replica, merely because it is the original. By parity of reasoning, a successful innovation in sport has additional aesthetic value just because it is a new creation. The genius is one who can provide this extra aesthetic pleasure and on that basis is rightly valued. The genius need not be conscious of how they achieve such innovations and thus find their own genius to be something they cannot explain but only demonstrate. In sport, innovations that offer new ways of playing or solving problems can produce competitive success which demands instant recognition and rewards.  相似文献

Abstract

The relationship between junior boys' tennis success, as measured by a top 20 International Tennis Federation's Junior Circuit (ITFJC) ranking, and subsequent ranking accomplishments in professional men's tennis is discussed. The names, countries, and birthdates of all players to achieve a top 20 ITFJC boys' year-end ranking from 1992 to 1998 were recorded. The progress of these players through the professional ranks was then tracked to the end of 2004. Results indicate that 91% of top 20-ranked boys achieved a professional men's ranking, while a stepwise regression analysis revealed junior ranking (JR) to be a predictor of future, professional ranking (β = 0.232, r 2 = 0.054, p < 0.05). A regression equation [predicted professional rank = 78.17 + 6.31?(JR)] accounted for a significant amount of variance in professional ranking. For male players, therefore, the achievement of a top 20 junior ranking appears to be a reasonable yardstick for future, professional success. The type of surface upon which junior players develop their games was also shown to influence professional ranking highs, with play on clay courts or a combination of clay and hard courts helping to produce higher, professionally ranked players than hard court play alone (p≤ 0.01).  相似文献
