政策网络视角下农村人居环境整治的参与网络治理研究--基于A镇的案例分析     

谢晓晓 《黄冈职业技术学院学报》2020,(1):78-82

借鉴罗茨的政策网络治理理论框架,对A镇农村人居环境整治中各参与主体构成的参与网络展开研究,研究发现:各主体之间的关联性较为松散,尤其是议题网络与生产者网络之间关联性欠缺会提高生产者网路对社会效益的忽视程度,并且生产者网络和议题网络中的多数主体参与能力有欠缺。提出应建立一个整合性的网络治理结构,增强各参与网络之间的关联性,尤其要建立专业网络、生产者网络和议题网络之间的关联性和依赖性。  相似文献

高校精品课程网站建设阻碍因素与有效传播策略     

谢彩云  赵英  李华锋 《现代远程教育研究》2012,(6):83-88

精品课程网站既是精品课程建设和共享的载体,也是课程资源呈现和评价的窗口。目前我国高校精品课程网站建设现状不容乐观,在网站信息组织方面,栏目设置混乱,信息表现形式单一枯燥,网站平台色调不符合学科特征;在网站功能方面,资源共享程度偏低,偏重内容展示但忽略了和学生的互动,这在一定程度上阻碍了精品课程资源的开放与共享。从使用者的需求来看,精品课程网站导航栏目建设应进一步规范化;信息表示方式应多元化,充分发挥其媒介功能;网站平台结构应相对稳定,风格与色彩应符合学科特征;交互方式应多样化,资源获取途径应具有针对性。  相似文献

Pupil mobility and educational achievement in schools: an empirical analysis     

Feyisa Demie 《Educational research; a review for teachers and all concerned with progress in education》2013,55(2):197-215

One of the problems facing education policy-makers is how to raise achievement in schools. Improving schools and raising achievement requires, at the very least, an understanding of the factors influencing performance in schools. Previous research has looked at a number of factors, including quality of teaching and learning, patterns of resource use, gender, ethnicity, social class and socio-economic background in schools, but there has been little empirical research into the effect of pupil mobility on school performance. Pupil mobility in schools also has implications for many important policy areas, such as school funding, target-setting and league tables, and yet it is only just beginning to be recognized as an important policy issue. This paper examines the relationship between pupil mobility and educational achievement in an inner city LEA. The performance of three cohorts of pupils at key stages 2 and 3 and GCSE are analysed by the mobility factor to illustrate the effect of pupil mobility on educational attainment. This is followed by a discussion of the causes of pupil mobility in schools and strategies adopted by schools to address mobility problems. The final section of the paper addresses the implications of the empirical evidence for school improvement strategies and funding allocations.  相似文献

近几年,随着职业学校的扩招,在校生规模越来越大,对如何培养适应新时代发展所需要的应用型人才是职业学校所面临的一个新的课题。因为未来人才必需具备获取新知识的能力,具备发现问题、解决问题的能．力和创新意识,只有这样,他们才能尽快地适应社会,使自己尽快融入社会的发展中,所以,对于我们职业学校特别是专业课教学提出了更高的要求。这就要求我们在专业课堂教学中,更新观念,改革课堂教学方式,提高教育教学效果,努力提高学生对本专业各门课程的兴趣,搞好在校学习,为以后的工作打好基础。  相似文献   

Changing boards: investigating the effects of centres changing their specifications for English GCSE     

Eva Malacova 《Curriculum Journal》2013,24(1):27-35

The awarding bodies and their regulator carry out research to maintain the equivalence of examination standards. However, some criticisms remain, suggesting that examination boards may be lowering standards in specifications (syllabuses) in order to attract more centres (schools or colleges). This article reports our investigations on whether centres that decide to change their specifications do so to a specification with a higher percentage of candidates achieving grade C and above, based on the argument that such specification is easier. Using GCSE English data for the years 2000–2003, we show that there is insufficient evidence for this assumption; instead, alternative explanations may be more plausible. We then consider whether centres that changed their specifications improve their mean level of performance more than centres that did not change. There was not enough evidence for this second assumption either.  相似文献
