New displays, galleries and exhibitions in museums and galleries are increasingly subject to summative evaluations, wide-ranging investigations that examine how visitors respond to and engage with particular initiatives. These evaluations provide insights into the behaviour and attitudes of visitors and the ways in which particular exhibitions, exhibits and information resources facilitate engagement, participation and learning. Unfortunately, however, summative evaluation has relatively little impact either on the particular initiative or more generally in contributing to our knowledge of visitor behaviour and understanding of best practice. In this paper, we suggest that the relative lack of impact of summative evaluation is not primarily due to any methodological shortcomings or the idiosyncrasies of some of the approaches that are used. Rather, the organisational and institutional context in which summative evaluation is commissioned, undertaken and received can impose contradictory demands and undermine the opportunity of learning from and applying the findings of evaluation.  相似文献

Late school entry is driven by several factors, one of the key ones being the cost barrier to schooling. Policies such as free primary education (FPE) that advocate for universal coverage are therefore partly aimed at removing the cost barrier. The Kenyan Government, like many in sub-Saharan Africa (SSA), introduced FPE in 2003 with the aim of universalising access to schooling, which is one of the eight United Nations Millennium Development Goals (MDGs) it signed up to achieve. Based on a case study of four sites in Nairobi, the aim of this paper is to assess whether the FPE policy has affected late enrolment. The data used were collected by the African Population and Health Research Center (APHRC) and comprise a sub-sample of 4,325 first-graders during 2000–2005. The paper applies a probit model to assess the impact of the policy on the basis of marginal effects on the predicted probability of late enrolment. The results show that the FPE policy reduces the probability of late enrolment by 14 per cent. The reduction in probability of late enrolment was greater among children residing in slums (16 per cent) than those in non-slums (9 per cent). The main implication of the findings for policy makers is that cost barriers are a likely cause of over-age enrolment.  相似文献

Cultural variation in relations and moment‐to‐moment contingencies of infant–mother person‐oriented and object‐oriented interactions were compared in 118 Japanese, Japanese American immigrant, and European American dyads with 5.5‐month‐olds. Infant and mother person‐oriented behaviors were related in all cultural groups, but infant and mother object‐oriented behaviors were related only among European Americans. Infant and mother behaviors within each modality were mutually contingent in all groups. Culture moderated lead–lag relations: Japanese infants were more likely than their mothers to respond in object‐oriented interactions; European American mothers were more likely than their infants to respond in person‐oriented interactions. Japanese American dyads behaved like European American dyads. Interactions, infant effects, and parent socialization findings are set in cultural and accultural models of infant–mother transactions.  相似文献

The Tkatchev on the high bar is a release and re-grasp skill in which the gymnast rotates in a direction during flight opposite to that of the preceding swing. Since the release window is defined as the time during which the gymnast has appropriate linear and angular momentum to ensure the bar can be re-grasped, it was speculated that the release windows for this skill would be smaller than for dismounts that are less constrained. One senior male gymnast competing at national standard performed 60 Tkatchev trials. A four-segment planar simulation model of the gymnast and high bar was used to determine the release windows in 10 successful and 10 unsuccessful performances of the Tkatchev recorded using a Vicon motion analysis system. Model parameters were optimized to obtain a close match between simulations and recorded performances in terms of rotation angle (1 degree), bar displacements (0.01 m), and release velocities (1%). Each matched simulation was used to determine the time window around the actual point of release for which the model had appropriate release parameters to complete the Tkatchev successfully. The release windows for the successful trials were small compared with those of dismounts. The unsuccessful trials were associated with later release and later timing of the actions at the shoulders and hips.  相似文献
