CuO对Bi(Pb)—Sr—Ca—Cu—O系微晶玻璃超导性能的影响

用DTA、XRD、SEM等手段研究了Bi_(0.7)Pb_(0.3)Sr Ca Cu_x O_y(x=1.6,1.8,2.0,2.2,2.4)系统微晶玻璃的品化过程、晶相组成和晶体形貌,详细讨论了CuO对该系统高Tc超导相2223、2212形成以及对超导性能的影响.研究结果表明,CuO含量增加有利于超导相的形成,且随着CuO含量增加,在CuO=2.0mol附近,该系统超导性能呈现最佳值.     

Mathematical identity in women: The concept,its components and relationship to educative ability,achievement and family support

Mathematical identity and its relationship to mathematical achievement, educative ability and study support were studied among 133 women enrolled in the Swedish adult education system. A model of mathematical identity was constructed including self‐perceived mathematical knowledge, ability, motivation and anxiety. This model was transformed into a statistical factor model, tested using Lisrel. An acceptable fit was obtained. The first three factors were strongly negatively related to mathematical anxiety. The mathematical identity components correlated most strongly with earlier school grades in mathematics and, to a lesser extent, with the result of a diagnostic test. Unexpectedly, the relationships to educative ability and study support were weak. Using a person‐oriented approach, three typical patterns were found: one with extremely positive, and two with extremely negative, mathematical identity. The implications for further research are to investigate stability and change in the mathematical identity of women taking part in recurrent education.     

论高职"两课"教学内容的选择

高职“两课“面临课时限制教学内容和选择教学内容随意性的问题，广西教育厅已布置今年8月开始进行全面调研经研究和调查，笔者认为教学内容主要有主流意识的“满堂灌”与大学生释疑解惑的要求不完全吻合、应用性不够突出、内容重复、综合运用训练欠缺等问题，我们应以“必需”、“够用”为原则、以学生成才为出发点选择教学内容．以课程基本理论为主，多门渗入．以教学方法的改革促进教学内容的改革“两课”的核心内容和基本要求是相对稳定的，但外围部分须随时代发展和学生需求变化而更新。     

The Phenomenon of False Assumption in Historical and Educational Texts

This article describes two heuristic strategies for problem solving: the use of false assumption strategy and the use of double false assumption strategy. Both of these strategies have their roots deep in history. In this article, we define these two strategies and illustrate their use in a problem developed by Frances Pellos. The article provides an overview of occurrences of these two strategies in various mathematical and educational texts. The texts show clearly that both of these strategies played a significant role in mathematics education in the past. We present some examples from concrete historical documents, which we use later for the preparation of a teaching experiment. We also present the conclusions of an experiment conducted on three lower secondary schools in the Czech Republic, the goal of which was to test the applicability of the use of false assumption strategy as a propaedeutic to solving word problems using equations.

以期刊发表时滞和动态评估模型分析比较7种建筑工程类高校学报

为客观地评价建筑工程类高校学报的学术质量和学术影响力,对7种建筑工程类高校学报2003～2007年的评价指标进行了比较分析.结合各刊文章的发表时滞,希望通过对各刊的动态评估及计量学数据的比较分析,能客观、真实和可靠地评估期刊的学术地位.结果显示,期刊的他引率、基金论文比偏低,个别期刊论文发表时滞较长.同时显示,5年来各刊的论文学术质量、学术影响力和编辑水平都有较大的提高.     

International handbook of education for the changing world of work: bridging academic and vocational learning,vol. 2 of 6

This article presents one approach to assessing the impact of an online professional practice doctorate in education on participants' work environments. It is unique in that it explored impact during the doctoral program, before participants began their dissertation research, and it focused on how participants apply learning from the program within their practice and how they grow professionally in ways that make contributions to their organizations and their profession. The data are based on participant interviews, participants' curriculum vitae submitted during qualifying exams, and professional websites. The findings indicate that an online professional program embedded in practice can have powerful impact within a short period of time on students' own practice, their local organizations, and their colleagues at regional, state, and national levels and spur their professional momentum.

“第一手的生活”与“第二手的教化”——教育价值观的应然与实然

教育的原初精神在于提升人的内心世界的境界,致力于让人们过上“第一手的生活”,工业时代理性精神的核度发展破坏了教育的最初指向,将工业化的操作范式引入到教育中,致使教育沦为“第二手的教化”,教育价值观在工业时代中失去了它的崇高。我们处于“相对的时代”,在时代的文化价值硬发生变化的同时,教育的价值坐标也发生了相应的变化,理想性重返教育,创造与对话成为教育中新的理念。
