针对当前网络搜索引擎未能较多地关注用户需求、查全率与查准率不高、彼此间不兼容的缺陷,提出建立基于用户需求的元搜索引擎,并分析其基本原理,给出其基本结构,讨论其运行机制和关键技术。指出基于用户需求的元搜索引擎可使网络信息资源在一定程度上结构化,实现网络信息资源的自组织,提高网络信息检索的查全率和查准率.  相似文献   

我国教育智慧研究20年:成绩、问题与展望     

刘旭东  王成军 《课程.教材.教法》2018,(3):16-23

我国教育智慧研究经历了起步期、迅速发展期和深化拓展期,并在理论研究、专业研究机构形成、成果交流与传播、实践反思和总结等方面取得了较好成绩,但同时存在学理依据不足、概念模糊、构成要素不明、行动逻辑认识不足等问题。以量化考评为主的管理体系、凌乱而超负荷的教育要求、功利性的专业伦理、教师的工作惯性等现实障碍影响着教育智慧的生成及应用。深入推进我国教育智慧研究,需要加强元研究层面的反思,并重构教育智慧研究的方法论;应重视智慧教育背景下教育智慧研究的新课题,并加强对"卓越教师"教育智慧的探索。  相似文献   

国家安全之外的《国防教育法》——20世纪中期美国教育改革起源的再审视     

王慧敏 《高等教育研究》2018,(10):100-109

1958年颁布的《国防教育法》对认识二战后美国的教育变革有重要意义。但长期以来研究者都视其为对"苏联卫星事件"的回应,是冷战时期国防政策的重要内容。笔者通过对文献的重新发掘与分析,指出两者之间不存在必然联系,这场教育改革不是"刺激-反应"模式的产物;此外,该法案立法过程中的焦点问题是对联邦政府干预教育权限的再讨论;法案通过后,在宣誓政治忠诚和学术自由问题上也受到广泛批评。国家安全不能概括法案的全部,至于联邦政府如何干预教育,以法案为代表的每一次讨论本身就是答案。  相似文献

赵炬明 《高等工程教育研究》2018,(2):30-44

本文是美国"以学生为中心"的本科教学改革研究之三,主要介绍在这场改革中美国学者和教师创造的行之有效的实践和方法。全文共九部分。第1~3部分介绍相关文献、科学基础和大学教学有效性双因素假设。第4~6部分介绍由科学研究、受生活与职业发展影响和由经验总结而产生的实践与方法。第7部分是SC方法论,讨论了"SC方法树"、"3650"框架和5个"方法论误区"。第8部分是关于SC改革的未来,介绍了颠覆性创新概念和两所创新性学校。文章特别强调了设计在课堂教学模式改革中的核心作用。好的设计能把SC原则贯穿教学实践,能结合学生实际,促进学生有效学习。由于原文较长,故分为上下篇发表。上篇包括前四部分,下篇包括后五部分。  相似文献   

Enhancing Research Impact in Heritage Conservation     

Theocharis Katrakazis  Cath Dillon  Petra Juvan  Stavroula Golfomitsou 《文物保护研究》2018,63(8):450-465

This paper examines how research impact is defined, measured, and generated – with a view to understanding how it can be enhanced within heritage conservation. It examines what is meant by ‘impact’ and how it can be promoted within heritage science through effective inter-disciplinary collaboration. Following a general examination of the current discourse concerning research impact, the study examined: (i) active research networks within heritage science; (ii) research planning and evaluation practices within heritage science; and (iii) the experiences of users (i.e. conservators and other heritage professionals) within research collaborations. Terminologies surrounding the notion of impact and the various phases of the research process were reviewed – from the initial identification of a knowledge gap to the eventual application of new findings in practice. Next, the reach and diversity of research collaborations (as identified through publication co-authorship) were studied to characterise the inter-disciplinary nature of heritage science and its connectedness to users. Findings showed substantial growth in international research collaborations over recent years, predominantly involving academic- and research-oriented institutions – although the engagement of heritage institutions has proportionally decreased. In addition, a worldwide survey of institutional planning and evaluation practices revealed a general reliance on processes driven by the interests of researchers – the systematic consideration of stakeholder opinion and evaluation of research outcomes being less common. Finally, a series of semi-structured interviews with senior heritage professionals explored their experience of collaborative research. The results identified key areas where strategic support is needed to promote user participation and enhance impact. These include training for research readiness, engagement, and impact for both researchers and users; better methods for needs and outcome assessment; affordable open access options and greater diversity of knowledge exchange opportunities. Finally, the need for ethical guidelines for responsible research, and greater emphasis on non-academic impact within research rating systems are discussed.  相似文献

The effect of the integration of students with special educational needs: Evidence from Chile     

《International Journal of Educational Development》2020

This paper studies the effect of the integration of students with Special Educational Needs (SEN) on the academic achievement of their peers without SEN. This achievement is measured using performance in standardized reading and mathematics tests. The study also evaluates the effect of a policy that recognizes and increases resources for special educational needs that had not yet been considered and improves education provision protocols for students with SEN. Using administrative data and standardized test scores, we constructed a panel that follows a cohort of students before and after the reform, determining for each individual and year whether the class to which he/she belongs has any students with SEN. Our identification strategy employs panel data with fixed effects at the school, individual, and time levels. Estimates show that, on average, having a peer with SEN in the classroom has a negative effect on the academic performance of students without SEN. However, these effects are small and decrease, or even vanish, once better inclusion policies are in place. These results suggest that the effect on peers is almost totally canceled when more resources are provided and when adequate treatment and support protocols are implemented.  相似文献

The impact of a professional development programme on teachers' attitudes towards inclusion     

DAWN B. MALE 《Support for Learning》2011,26(4):182-186

This article describes a study that aimed to answer the following question: ‘Will a programme of professional development in the area of special and inclusive education be effective in achieving attitudinal shift in teachers?’ Forty‐eight teachers who were enrolled on a Master's programme in Special and Inclusive Education were surveyed via a questionnaire at the beginning and end of a ten‐week introductory module. The results indicated overall attitudinal shift and attitudinal shift for four categories of inclusion to suggest more positive attitudes at the end of the module, compared with at the beginning. The implications for providers of pre‐ and in‐service education and training courses for teachers are discussed.  相似文献
