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

We investigate the value creation or destruction associated with the introduction of software patents in the United States in two ways. The first looks at the cumulative abnormal returns to Information and Communication Technology (ICT) firms around the time of important court decisions that impacted software patents, and the second analyzes the relationship between firms’ stock market value, the sector in which they operate, and their holdings of software patents. We conclude that the market evaluated software patents as a negative development ex ante. Ex post, a greater number of firms in all ICT sectors invested in these patents, and these firms had slightly higher market values than those with no software patents. However, while we obtain clear evidence that the technological importance or quality of patented innovation mattered for the market value of hardware firms both before and after the legal changes, it is less clear that the marginal patent right per se was associated with increases in market value, and there are no significant valuation effects associated with patents for pure software firms after the change. 相似文献

What is Evidence-based Education? 总被引:6,自引:0,他引:6
Philip Davies 《British Journal of Educational Studies》1999,47(2):108-121
This paper argues that education should become more evidence-based. The distinction is made between using existing research and establishing high-quality educational research. The need for high-quality systematic reviews and appraisals of educational research is clear. Evidence-based education is not a panacea, but is a set of principles and practices for enhancing educational policy and practice. 相似文献

This paper examines a range of issues concerned with the process of choosing schools in the private and state sectors at the primary/pre‐preparatory stage and at the time of transfer to secondary/senior school. The findings indicate that choices about schools are made at different times and in different ways by parents who use the state and private sectors. One of the key findings is that the process of choosing a school begins earlier in the private than in the state sector; another is that quality of education is cited more frequently as one of the ‘top three’ essential factors by parents of children in the private sector. At both the primary and transfer to secondary stages, very high percentages of parents consider it essential that their child should be happy. A discussion of the different notions that private school and the state school parents may have of ‘happiness’ is offered. 相似文献

This paper argues that although new problems are encountered as field experience programs grow larger, the basic principles of assuring educational quality remain the same. One large field experience program, the Washington Center for Learning Alternatives, and the method of educational quality control developed by that program are described. 相似文献
