Developing and validating an instrument measuring school leadership     

Jianping Shen  Xin Ma  Louann Bierlien Palmer  Sue Poppink  Walter Burt 《Educational studies》2019,45(4):402-421

In this study, we developed and validated an instrument that researchers can use to measure the collective effort of principals and teachers who excise their own unique leadership to generate (integrated) school leadership. Based on 644 teachers, we found sound psychometric properties of the scales of the instrument and the instrument as a whole. We also explored the predictive properties of the instrument in predicting student achievement at the school level. Based on 53 schools, we found that the instrument can indeed measure the kind of school leadership that really matters to student achievement. When predicting student achievement (at the school level), the instrument tends to be more sensitive to more difficult school subjects (e.g. mathematics), implying that improvement in school leadership would lead to larger improvement in student achievement (at the school level) in more difficult school subjects.  相似文献   

关于民族高校语言学专业观念更新问题的思考     

康亮芳 《湖北第二师范学院学报》2012,(7):100-102

全球化势不可挡的今天,我们的语言教学遇到很多新的问题,民族院校面临的语言教学状况更为复杂。要切实发挥培养人才,服务地方的职能,民族高校语言学专业应及时更新观念,主动传递新思想,引导更多的各族学生以开放的语言视野,面对当代语言生活的需要,在主动积极学好少数民族语言的同时,努力学好国家通用语,学好外语;同时通过学生影响当地的社会人群,在民族地区的"语言沟通"和"语言保护"中发挥积极的作用。  相似文献   

社区矫正价值的实现——以暂予监外执行罪犯的矫正为中心     

侯启舞 《昆明师范高等专科学校学报》2012,(5):64-66,71

“人道、安全、正义”是矫正罪犯,尤其是矫正暂予监外执行罪犯理应追求的价值。为实现人道价值,应解决保外就医者的保证人及困难对象的帮扶问题;为实现安全价值,应解决好续保和吸毒人员的监管问题;为实现正义价值,应确保暂予监外执行不被滥用问题。  相似文献   

Educational Marketisation and the Head's Psychological Well–Being: A Speculative Conceptualisation     

Izhar Oplatka  Nick Foskett  & Jane Hemsley–Brown 《British Journal of Educational Studies》2002,50(4):419-441

One of the most important changes in the environment of schooling during the last decade has been the establishment of educational markets and inter–institutional competition which, in turn, has led to the development of a new management culture in schools. In the light of these developments, this paper draws together the research on heads' responses to marketisation and suggests theoretical hypotheses on the impact of its underlying features on their psychological well–being. Our argument is that the major features of educational marketisation may promote the emergence of both the determinants of professional growth and self–renewal and of occupational stress and job burnout among headteachers. These determinants, in turn, lead to the appearance of two types of well–being among school heads. To support our hypothesis we refer to the work of others and empirical findings from various fields of study.  相似文献   

更新与转换：可持续发展与人类发展观的嬗变     

包庆德 《内蒙古大学学报(人文社会科学版)》2001,33(2):35-42

发展问题一直是世界各国普遍关注的焦点问题。持什么样的发展观念，走什么样的发展道路，达到什么样的发展目标，是国际社会聚讼不已、莫衷一是热门话题。20世纪60年代以来，由于东西方冷战对峙、南北方发展冲突、全球性生态危机，促使人们开始检讨传统发展观，寻求探索新的发展模式。20世纪80年代以来可持续发展观在全球范围的提出，标志着人类发展观的重大变革。而这一变革是在人们对传统发展观的内在缺陷及其在实践中导致的巨大负面效应的深刻反思过程中实现的，其实质是人们关于社会发展的价值观念的全面更新和创造性转换。  相似文献

When academics integrate research skill development in the curriculum     

J. W. Willison 《高等教育研究与发展》2012,31(6):905-919

This study considered outcomes when 27 academics explicitly developed and assessed student research skills in 28 regular (non-research methods) semester-length courses. These courses ranged from small (n?=?17) to medium-large (n = 222) and included those from first year to masters in business, engineering, health science, humanities and science, across five universities in three Australian cities. The two-year study used three data sets to determine the outcomes of development and assessment initiatives: student pre- (n?=?779) and post-questionnaires (n?=?601), interviews with students (n?=?46) one year after completing a course that developed research skills and interviews with academics (n?=?17) involved in developing and assessing student research skills. These multiple sources provided evidence that students developed a variety of discipline-specific research skills and that these skills were useful for subsequent studies and especially for employment. Academics indicated that the process of making explicit the development of student research skills led to enhancement of their teaching, helping the academics to clarify major course purposes as well as enabling them to provide more substantial feedback to students than in the past. Academics also indicated that this teaching process changed their understanding of disciplinary research and, for some, even suggested new directions in their research.  相似文献   

George W. Bush's post-September 11 rhetoric of covenant renewal: upholding the faith of the greatest generation     

Denise M. Bostdorff 《Quarterly Journal of Speech》2013,99(4):293-319

The appeal of Bush's post-September 11 discourse lies in its similarities with the Puritan rhetoric of covenant renewal by which ministers brought second- and third-generation Puritans into the church. Through this epideictic discourse, Bush implored younger Americans to uphold the national covenant of their “elders,” the World War II generation, through support of the war on terrorism, and he revitalized the faith of the older generation. Bush's covenant renewal rhetoric in the context of September 11 inaugurated him into the presidency. It also explains his predilection for unilateral and/or pre-emptive action and his call for acts of local community service.  相似文献
