Abstract This paper explores the beneficial outcomes that visitors seek and obtain from a museum visit, in terms that are not related to learning outcomes. It uses a deductive qualitative approach to investigate the meaning and value of a museum visit from the visitors' perspective. Three different levels of the meaning of the experience are considered: the attributes of the setting that visitors value; the experiences they engage in; and the benefits they derive. The findings confirm the importance of the “satisfying experiences” framework for understanding visitor experiences in museums, and extend this understanding in relation to the beneficial outcomes these experiences produce. The study also highlights the importance of “restoration” as an outcome of a museum visit. It is argued that the concept of the museum as a restorative environment, which enables visitors to relax and recover from the stresses of life, is worthy of further research attention. These insights will enable museum practitioners to better understand and meet their visitors' multiple needs and expectations.  相似文献

For most teachers in the United States, teaching is no longer a career-long occupation. This article examines the narratives of a particular group of leavers, former teachers who made significant investments in their teacher training and who taught for at least three years before making the decision to exit. The accounts of these invested leavers are used to look at workplace change as a motivating factor for teacher exit, particularly changes in classroom authority that occur after teachers have begun to feel competent.  相似文献

This study investigates the impact of an innovative conservation action campaign called Penguin Promises implemented at uShaka Sea World in Durban, South Africa. Communication tools included interpretive signage, exhibits with and without animals, presentations, and personal interactions, along with a specially designed postcard, on which visitors could write a promise (pledge) to make a change in their daily lives to become more environmentally responsible. Visitors who completed a card were contacted a year or more after their visit and asked about the outcomes of their promise. The results (N = 316) showed that 49.4% of respondents could give an example of something positive they had done for the environment, that they attributed to the campaign. Based on the study, recommendations are provided for the design of effective visitor conservation action campaigns.  相似文献

ABSTRACT

Water polo players require a high level of upper-extremity strength, flexibility and coordination to achieve a peak level of throwing performance. Increased levels of shoulder proprioceptive acuity, strength and range of motion (ROM) have been previously associated with higher sporting performance. A coach-rating scale, used to quantify an athlete’s kicking proficiency in soccer; was adapted in the current study to measure each coach’s subjective expert opinion regarding athletes’ throwing mechanics, velocity, and accuracy. To examine this hypothesis shoulder proprioception acuity of 18 water polo players was measured both in-water and on-land using an AMEDA apparatus and correlated with coach-rated throwing performance and clinical measures of shoulder strength and ROM. There was a moderate positive correlation between the in-water and the on-land proprioception acuity (r = 0.47, p < 0.05). The in-water score showing a strong positive correlation with coach rated throwing mechanics (r = 0.68, p < 0.05) and velocity (r = 0.75, p = 0.02), suggesting that superior proprioception acuity contributed to fast, mechanically-efficient throwing. These findings support the notion that in-water proprioceptive acuity is an important determinant of the throwing performance achieved by water polo athletes and its measurement may be a valuable adjunct to current athlete screening.  相似文献

Strenuous physical exercise induces oxidative stress. There may be a number of sources of this oxidative stress, including mitochondrial superoxide production, ischaemia-reperfusion mechanisms and auto-oxidation of catecholamines. Severe or prolonged exercise can overwhelm antioxidant defences, which include vitamins E and C and thiol antioxidants, which are interlinked in an antioxidant network, as well as antioxidant enzymes. Evidence for oxidative stress and damage during exercise comes from direct measurement of free radicals, from measurement of damage to lipids and DNA, and from measurement of antioxidant redox status, especially glutathione. There is little evidence that antioxidant supplementation can improve performance, but a large body of work suggests that bolstering antioxidant defences may ameliorate exercise-induced damage, suggesting that the benefits of antioxidant intervention may be for the long term rather than the short term.  相似文献

School size is becoming an increasingly important factor in discussions concerning school effectiveness, particularly those concerning cost‐effectiveness. Unfortunately, the term ‘small‐school’ is used in several different ways and lacks clarity. This paper examines the present usage of this term in order to construct a definition that could be incorporated into effectiveness research design.  相似文献

ABSTRACT

The year 2015 was significant for the arena of international development, as UNESCO’s Education for All agenda was replaced by Education 2030, which would identify minimum standards of education quality. The OECD had been working on extending its existing PISA assessment into low- and middle-income countries through PISA for Development (PISA-D) and positioned the new assessment as a means of tracking progress on the post-2015 goals. The organisation maintains that PISA-D was introduced primarily in response to the demands of the international community, especially low- and middle-income countries, and that the assessment was developed in partnership with them. This paper investigates those claims through an analysis of the arrival of PISA-D in Cambodia, situating the analysis within UNESCO’s shifting agenda and the strategic visions of the OECD and World Bank that first emerged in the 1990s. The result is a very different picture to the portrayals of local agency, demand, consensus and partnership that adorn the official websites and pamphlets of global agencies and much academic research, raising serious doubts about education governance post-2015.  相似文献

Intervention researchers often use curriculum‐based measurement of reading fluency (CBM‐R) with a brief experimental analysis (BEA) to identify an effective intervention for individual students. The current study synthesized data from 22 studies that used CBM‐R data within a BEA by computing the standard error of measure (SEM) for the median data point from the baseline and intervention data. The median CBM‐R score from the intervention that the authors of each study identified as most effective fell within the SEM (68% confidence interval) of the baseline data approximately 30% of the time, but the ranges for the two author‐identified most effective interventions overlapped over 75% of the time. Extended analyses were consistent with the BEA results for approximately three‐fourths of the instances after considering the SEM of the baseline and intervention phases. Using matched passages did not improve the overlap of the ranges, but there was less overlap when the study used three data points per condition. Results emphasize the importance of considering SEM of CBM‐R data when comparing interventions within a BEA. Further implications for practice and future research are included.  相似文献
