虚拟学习社区的自组织性及形成条件

虚拟学习社区具有自发、自管、自调的特点,与自组织理论的基本内涵呈现极强的内在耦合性,如果社区中的学习者建构合理的身份认同与自我效能感、又具有一定规模的参与人数、发表的作品及跟贴达到一定数量、社区中教师具备沟通智慧与反思习惯、社区中的知识权威和意见领袖发挥影响、教育主体之间建立有效的心理契约这几方面满足了耗散结构的产生条件,虚拟学习社区就会出现自组织的特征,由无序走向有序,形成非线性复杂系统。     

关于运动解剖学的几个基本概念

力和力矩是两个不同的概念，应加以区别使用；肌肉工作时定点的确定要以躯体支撑点为基本参考点，肌肉做静力性工作时是双固定状态；肌肉拉力线应用射线来标示；要根据具体情况作具体分析，不能简单地以动点向定点的连线标示，影响肌肉最大力量的解剖学因素是该肌肉内可能形成的最大横桥数目和肌肉收缩时的初长度，神经调节、肌拉力角、肌收缩矩均不是影响肌肉最大比力的解剖学因素．

The one-in-ten: quantitative Critical Race Theory and the education of the ‘new (white) oppressed’

ABSTRACT

This paper challenges the notion that quantitative data – as a numeric truth – exist independent of a nation’s political and racial landscape. Utilising large-scale national attainment data, the analysis challenges the belief that ‘White working class’ children in England, especially boys, are ‘the new oppressed’ – as a former equality adviser has publicly claimed. The analysis applies Quantitative Critical Race Theory, or ‘QuantCrit’, an emerging quantitative sub-field of Critical Race Theory in education. The paper argues that far from being ‘oppressed’, White boys continue to enjoy achievement advantages over numerous minoritised groups; especially their peers of Black Caribbean ethnic origin. Additionally, the analysis uniquely exposes racialised trends of ‘equivalency’ in core subject qualifications, whereby minority ethnic children are over-represented in certain lower-status qualifications that are counted as equivalent in education statistics but not in the real world labour market. The analysis concludes that knowing misrepresentations of quantitative data are at the heart of an institutional process through which race and racism are produced, legitimised and perpetuated in education.     

Relating early childhood teachers’ working conditions and well-being to their turnover intentions

High turnover rates of early care and education teachers reduce the quality of education; unsatisfied teachers, suffering from stress or emotional exhaustion, are less equipped to promote children’s development and more likely to leave the classroom. We used data from a national survey of US early childhood educators (n?=?1129) to examine associations between teachers’ working conditions, well-being, and motivation with professional commitment and turnover intentions to move, leave, or remain. Multiple regression analyses revealed that more intrinsically motivated teachers were more likely to report intentions to move over leave, emotionally exhausted teachers were more likely to report intentions to leave, and lower teacher-reported working conditions predicted intentions to move or leave the field over staying. The results suggest that teachers’ well-being and perceived working conditions relate with their intentions to remain at their job or within the field and to their commitment to the profession.

网络聊天语篇的语体特征

网络聊天(Internet Relay Chat)是网民在网络上借助聊天软件,主要通过文字媒介进行交流的人际传播活动,是一种多人参与的,基于纯文本的,实时的交流方式。因而,它既是一种交际事件,也是一种语篇类型。它既具有口语语篇的实时互动性,又具有书面语体的单向异步性,属于“互动性的书面语篇”。这种新兴语篇类型拥有独特的语境特点,更具有鲜明的语体特征,它模糊了口语和书面语的界线,实现了口语语体和书面语语体的高度结合。

论邓小平人力资本思想的形成及时代特征

邓小平理论中蕴含着丰富的人力资本思想,这些思想的产生,有其深刻的理论渊源和特殊的时代背景:马克思人力资本理论是其理论基础,中国改革开放和社会主义现代化建设的伟大实践是其产生的实践要求,西方人力资本理论的发展和完善与之相互策应,中华民族五千年思贤辩才的文化积淀是其历史渊源,新科技革命是其时代背景,而自身传奇的经历和超凡的素质是内在的决定因素。
