教师经验与随机的“形式聚焦”教学技巧之关系行动研究     

林梅  冒端 《河北北方学院学报(社会科学版)》2011,27(3):92-94

随机的＂形式聚焦＂是重要的教学法,因为它不仅促进人们对形式和意义的共同关注,更鼓励学生要注意语言形式。在研究教师引发的随机的＂形式聚焦＂教学技巧时,考虑教师的教育经验背景是非常重要的。通过行动研究发现,在数量和类型上,有经验的教师比没有经验的教师使用更多的随机的＂形式聚焦＂教学技巧。  相似文献   

Research characteristics on health law in China: Social network analysis     

Qing Chang  Chao Long  Mark A. Hall  Zhiguang Duan 《The Journal of Academic Librarianship》2019,45(2):126-136

To determine the nature and extent of the emerging field of “health law” scholarship in China, we retrieved 2956 publications about various aspects of health law published up through 2014 in 268 journals from the “Chinese Social Science Citation Index” and from the list of Chinese “Core Journals” maintained by the Peking University Library. By bibliometric analysis, we observed some interesting results which were different from our expectations. The collaboration network among Chinese health law (CHL) authors was relatively small, loose, unstable and early in its development. Kan Tian and Lixin Yang were leading authors, Renmin University of China was the primary institution, and Beijing was the predominant region studying Chinese health law (CHL). Kan Tian ranked 1st in the collaboration network and Lixin Yang published the most number of articles on CHL. Comprehensive universities made up the majority of institutions studying CHL, while medical colleges did not focus on health law research, possibly due to medical schools focusing mainly on clinical education and not attaching as much importance to social and humanistic aspects of medicine. Food safety, health administration, and the general principles of civil law were the main areas of focus in CHL research, which is basically in line with what we expected.  相似文献   

Smart elasto-magneto-electric （EME） sensors for stress monitoring of steel structures in railway infrastructure     

Yuan-feng DUAN  Ru ZHANG  Yang ZHAO  Siu-wing OR  Ke-qing FAN  Zhi-feng TANG 《浙江大学学报(A卷英文版)》2011,12(12):895-901

Steel structures are widely used in railway infrastructures. Their stress state is the most important determinant of the safety of these structures. The elasto-magnetic (EM) sensor is the most promising for stress monitoring of in-service steel structures. Nevertheless, the necessity of magnetic excitation to saturation due to the use of a secondary coil for signal detection, keeps from its engineering application. In this paper, a smart elasto-magneto-electric (EME) sensor using magneto-electric (ME) sensing units to take the place of the secondary coil has been exploited for the first time. The ME sensing unit is made of ME laminated composites, which has an ultrahigh ME voltage coefficient and can measure the magnetic induction simply and precisely. Theoretical analysis and characterization experiments firstly conducted on the ME laminated composites showed that the ME sensing units can be applied in the EM sensor for improved performance in stress monitoring. A tension test of a steel bar was carried out to characterize our smart EME sensor and the results showed high accuracy and sensitivity. The present smart EME sensor is a promising tool for stress monitoring of steel structures in railway and other civil infrastructures.  相似文献   

Optimal linear attitude estimators via geometric analysis     

De-ren Gong  Xiao-wei Shao  Wei Li  Deng-ping Duan 《浙江大学学报(A卷英文版)》2011,12(11):873-882

Three optimal linear attitude estimators are proposed for single-point real-time estimation of spacecraft attitude using a geometric approach. The final optimal attitude is represented by modified Rodrigues parameters (MRPs). After introducing incidental right-hand orthogonal coordinates for each pair of measured values, three error vectors are obtained by the use of dot or/and cross products. Corresponding optimality criteria are rigorously quadratic and unconstrained, which do not coincide with Wahba’s constrained criterion. The singularity, which occurs when the principal angle is close to π, can be easily avoided by one proper rotation. Numerical simulations show that the proposed three optimal linear estimators can provide a precision comparable with those complying with the Wahba optimality definition, and have faster computational speed than the famous quaternion estimator (QUEST).  相似文献   

公立高校教师聘任合同的法律适用     

段艳华 《现代教育科学》2015,(3):151-154

实行教师聘任制对高校落实依法治校、扩大办学自主权有着重大的现实意义。因对聘任合同法律性质缺乏统一的规定,各高校解决合同履行过程中所产生纠纷的方式差异较大。本文在厘清高校教师聘任合同主体的法律地位、明确高校教师聘任合同是私法主导性质的劳动合同的基础上,阐明以劳动争议解决机制保障合同双方合法权益的路径。  相似文献   

大学生生涯核心信念及其教育路径     

程婧  段鑫星 《现代教育科学》2015,(1):17-21

大学时期是生涯信念构建的关键阶段。个体在生涯展开的过程中,通常会进行如下自我追问:"我是谁?""我应当成为什么?""我是否能成就自我?"这一系列追问与自我认识、自我需求及其超越、自我效能三个方面相应,构建了生涯信念的核心部分。在混沌生涯背景下,生涯信念教育旨在提升个体生涯胜任力,通过引导个体构建开放性的自我认知系统,完善职业自我同一性;激发个体继起性的自我需求,发展多元职业认同;提升个体生涯自我效能,培养生涯应变能力等三个方面展开。  相似文献
