远程教育程序设计类课程教学方法的改革研究——以C＋＋语言程序设计为例     

纪福菲 《天津电大学报》2011,15(1):38-41

C＋＋语言程序设计作为计算机应用专业的基础课,在整个专业中有着举足轻重的地位。鉴于远程教育特殊的学习方式,加之该课程的学习内容比较抽象,导致教学过程难以推进。为改变重理论、轻实践的教学现状,提升教育教学质量,本文对C＋＋语言程序设计进行教学改革研究,并取得良好效果。  相似文献

The accessibility of Chinese local government Web sites: An exploratory study     

Yuquan Shi 《Government Information Quarterly》2007

With the rapid development of Chinese e-government, Chinese citizens are encouraged to access e-government services as their convenience. However, the accessibility of Chinese e-government Web sites has been overlooked. This research study tries to provide an overview of the accessibility of Chinese local government Web sites. Three hundred twenty-four Chinese local government Web sites were examined to find out how accessible they are with reference to the Web Content Accessibility Guidelines 1.0 (WCAG) published by the World Wide Web Consortium (W3C). This research found that all the surveyed Chinese e-government Web sites failed one or more W3C's accessibility measures and thus many disabled Chinese people may have substantial problems to access them. Several valuable recommendations are made based on the research findings and the China's actual conditions.  相似文献

C．Alisa与王姣bdFF动作起跳出台技术对比分析     

龙春生  薛淑君 《沈阳体育学院学报》2004,23(5):619-622

分析结果显示:C Alisa的bdFF动作的起跳及出台技术更加合理,其动作的运动学特征更加符合目前国际裁判对bdFF动作的评分理念和标准,即起跳后重心垂直升起高度要高,尽可能的"晚"转体和"快"转体,实现所谓的腾起后尽可能的"等待",而在转体中要有明确而清晰的周际间的"分隔"。与C Alisa相比较,王姣在起跳及出台技术的内涵和外部表象特征上存在着一定差距,这种差距是影响后继动作的完成质量及获得较高技评分值的根本原因。  相似文献   

Understanding others Kellyian theory,methodology and applicationComprendre les autres la théorie de Kelly: methodologie et applicationEntendimiemto de los otros la teoría de Kelly: metodología y applicación     

C.T.Patrick Diamond 《Int J Intercult Relat》1982,6(4):395-420

This article discusses Kelly's theory of personal constructs and its Repertory grid technique as means of revealing the nature of cultural differences and similarities. It shows how Kelly's theory relates to cognitive theory, implicit personality theory and subjective culture theory. According to Kelly, people and groups are best understood in terms of the ways they anticipate events. People are all psychologists since they employ constructs. These bases of discrimination are bipolar in nature and open to revision. A group's culture is summarized by its members' shared superordinate constructs. Kelly's Commonality Corollary explains that members of a group are similar because they use the same constructs to order events. Kelly's Sociality Corollary states that, in order to enter into a relationship with others, people need first to subsume the others' personal constructs. His custom-built Repertory grid elicits constructs by having a person decide how in a matrix other people, for example, are similar and different. In the rated grid form, each person or element is rated from most to least on the positive pole of each construct. Either principal components or cluster analysis or multidimensional scaling can reveal the interviewed person's superordinate dimensions of appraisal. As an emic technique, the grid is contrasted with the semantic differential and other fixed-format tests. A review of the personal construct literature shows that many individuals and cultural groups have been explained in their own terms. In this research, difference is construed as interesting and others are understood by construing their construction processes as a first step towards approval.  相似文献
