技职校院设置博士班课程问题

技职教育的主要目的,应该是培养具实务操作能力的学生,而在专门技术上有专精高超的能力;博士班课程则应培育有独立研究能力,能在专门学术领域中,有独到的学术理论理发现,可增进该领域学术水平。本文由美国加州高等教育体系的定位观察,进而探讨了技职教育体系设置博士班课程之因素及衍生的问题。     

《避暑山庄宫廷音乐》序言

还记得童年时随父亲在一个暑退凉生的农历七月十五的晚上,在武列河边,听家乡文人、画家何伯萍先生端坐在河畔诵经.当时还有年轻的倚声高手、山水画家张伯济等父亲的友好.晚风习习,新凉送爽,雅兴正复不浅.蓦然远远传来悠悠丝竹音乐之声,伴随着潺潺流水,是那么宁静、悠扬,忽远、忽近,复加唱经之声,顿时几位先生不约而同地说出:"这不是宫里十番又在沙堤门演奏吗."紧按着曼声低吟着杜甫的两句诗:"此曲只应天上有,人间能得几回闻."此刻大家都为之陶然心醉.我当时虽然不懂什么是雅兴,然而在幼小的心灵上却印上了一种飘飘乎的烙印,至今不变.     

Collaborative Reasoning: Expanding Ways for Children to Talk and Think in School

This article presents a framework to help teachers facilitate small group discussions about stories children read. Collaborative reasoning discussions are intended to create a forum for children to listen to one another think out loud as they learn to engage in reasoned argumentation. Children use personal experiences and evidence from the stories to support their conclusions and consider each other's points of view. Excerpts from an ongoing study of 12 fourth-grade classrooms in rural, urban, and suburban settings are used to illustrate four characteristics of cognitive reasoning: (1) children's response to text; (2) children's use of text to consider multiple possibilities; (3) children's use of tools for persuading others; and (4) children's control of topic and turn-taking.

Measuring argumentative reasoning: What's behind the numbers?

The aim of this paper is to develop a more thorough, empirically-based understanding of the differences in measurement of written argumentation when alternative scoring frameworks are employed. Reflective compositions of 127 elementary school children were analyzed using analytic and holistic scales. The scales were derived from Argument Schema Theory, an explicit model of argumentation development. We investigated the relationships among the different scales, as well as their relative reliability and efficiency. The scores derived using analytic and holistic methods have adequate reliability. Although less efficient, analytic scoring allows for gathering more sensitive and detailed information about the differences in student performance. The results suggest that the choice of an analytic framework for measuring argumentation should not be arbitrary, as each scoring method taps into distinct facets of the construct.     

去氢表雄脂酮在高原适应中的角色践的评定

1前言 DHEA和硫酸盐衍生物DHEA-S是人类最丰富的类固醇。从Baltimore的纵向研究认为老化、死亡与低血清DHEA-S和高胰岛素水平相关（Rothetal.,2002）。尽管没有很好描绘DHEA．S的生理角色和生物活动,但是已有文献证明DHEA．S有对压力的缓冲能力（Cruesseta1．,1999;Regelsoneta1．,1988;Grillonet a1．,2005）,     

透视美国数学教育研究项目——以受美国教育科学研究院资助的数学教育项目为例

分析近10年来由美国联邦教育部教育科学研究院资助的有关数学教育的96个研究项目,从一个侧面了解当前美国数学教育研究的项目特征与趋势.聚焦分析这些项目的关键特征,为此建立了含有6个维度的编码框架来对这些研究项目进行编码,并用图表展示统计结果.为数学教育研究者、实践者以及政策制定者更好地了解美国数学教育研究项目提供帮助,期望能为未来的数学教育研究项目提供一些方向性的参考.
