运用多个科学可视化软件,以中国知网(CNKI)中《教育学术月刊》2008年至2017年十年间所刊载的3038篇学术文献进行科学知识图谱分析.结果表明:围绕着教育领域进行调研,并对采集数据进行分析、挖掘、验证的科学实证研究类文章近年来得到大力的推崇,这类文章数据量大、推导性强、所占期刊版面多,导致期刊近年来的载文量降低,但理论学术水平却得以不断提升.北京大学、南京师范大学、北京师范大学、华东师范大学、江西师范大学、华中师范大学、南昌大学是发文量最多的重要研究机构.高等教育、职业教育、基础教育、教师专业发展、思想政治教育、心理健康教育、大学生就业与创业、教育公平、教学和课程改革是教育理论的研究热点.

To solve the problem of easily producing false edge and discontinuous edge of color image edge extraction algorithm,the adaptive vector variable color and color difference edge extraction scheme was proposed.According to the gradient and amplitude,an adaptive vector total variation denoising model was defined for reducing the influence of noise on edge.The image was transformed into a uniform CIELAB space to establish the color difference and direction.For diffe-rent color and direction,different Sobel operators and non maximal suppression were used to search for more edge points.Adaptive double threshold was used to extract image edge.Experimental results show that the proposed algorithm has better detection results with higher edge evaluak-tion factor F and lower Baddeley error compared with the traditional algorithm.

实践表明,传统的教室和机房的电脑以及学校的服务器会随着时间和使用率快速的老化,而更新的成本十分昂贵,本文提出了运用桌面虚拟化技术进行区域基础教育平台的搭建方案.通过成熟的云平台的安全可靠性和桌面虚拟化技术的灵活性、共享性等优势,来解决传统基础教育领域软硬件更新的问题.我们比较了多个著名的桌面虚拟化系统,并最终选择Citrix技术.最后详述了区域基础教育桌面云系统的基本架构设计,应用Citrix技术构建了面向区域基础教育的桌面虚拟化平台.

以中国知网(CNKI)中刊载的有关"云计算在教育领域运用"的论文为研究对象,对文章的关键词等数据进行文献计量分析.得出近十年来相关领域研究最多的是利用云计算平台进行教育信息资源的开发和整合,同时云协作平台、移动学习、优质教学资源共享也是相关的热点研究.

This paper take articles in CNKI database from 2008 to 2015 as research objects and conducts the viewable analysis and articles data including the authors, institutions, keywords and so on based on the principles of scientific metrology, bibliometrics, etc.and methods of word frequency, citation analysis as well as tools such as CiteSpaceIII and Excel, attempting to summarize the research hotspots of Journal of Hubei University of Education.In addition, this paper provides suggestion for articles and gives reference to the contributors.

This paper takes the articles related to "teaching skills of normal university students" in CNKI database from 2006 to 2016 as research objects and uses CiteSpace Ⅲ and other tools to implement bibliometric analysis and viewable analysis of the data in the articles including the keywords and so on.It is concluded that the reform and innovation of micro-teaching is most frequently referred in relevant research in the recent ten years.At the same time,in the context of information technology,the teaching skill training,practice teaching reform,training mode and effectiveness training are also hotspot research direction.

The construction of the traditional educational informatization which is relatively independent facing a huge dilemma, we propose a plan mixed the cloud platform and the use of its desktop virtualization technology to build a platform for primary education programs in the region. The security, full-covered characteristic of the cloud platform and the flexibility of desktop's virtualization technology, sharing, of thin clients, individuation and other advantages help to solve the traditional problem. We make a comparison of a number of well-known desktop virtualization systems in the article, and ultimately chose Citrix technology. Finally, the basic structural design of Primary Education Desktop cloud systems will be detailed, applying Citrix technology to build a desktop virtualization platform toward the primary education.
