Attitudes toward Dual Language Immersion Programs in China     

SHI Qing 《海外英语》2014,(22)

With the development of economy and the English learning reform in China,the role of English has increased than ever before.Dual language immersion(DLI)programs,as a new way to offer both languages and content instructions,will gradually take place of traditional English learning and become a new tendency in China.The attitudes of related groups toward the DLI programs are very important to its further development.This paper will first give a brief introduction to the current situation in China,and then analyze the attitude toward DLI programs,includingones of students,teachers and administrators,to find out problems existing in current DLI programs.  相似文献

Precision measurement of the Newtonian gravitational constant     

Chao Xue  Jian-Ping Liu  Qing Li  Jun-Fei Wu  Shan-Qing Yang  Qi Liu  Cheng-Gang Shao  Liang-Cheng Tu  Zhong-Kun Hu  Jun Luo 《国家科学评论(英文版)》2020,7(12):1803

The Newtonian gravitational constant G, which is one of the most important fundamental physical constants in nature, plays a significant role in the fields of theoretical physics, geophysics, astrophysics and astronomy. Although G was the first physical constant to be introduced in the history of science, it is considered to be one of the most difficult to measure accurately so far. Over the past two decades, eleven precision measurements of the gravitational constant have been performed, and the latest recommended value for G published by the Committee on Data for Science and Technology (CODATA) is (6.674 08 ± 0.000 31) × 10⁻¹¹ m³ kg⁻¹ s⁻² with a relative uncertainty of 47 parts per million. This uncertainty is the smallest compared with previous CODATA recommended values of G; however, it remains a relatively large uncertainty among other fundamental physical constants. In this paper we briefly review the history of the G measurement, and introduce eleven values of G adopted in CODATA 2014 after 2000 and our latest two values published in 2018 using two independent methods.  相似文献   

Exploring mechanisms of rapid automatized naming to arithmetic skills in Chinese primary schoolers     

Yiji Wang  Xiaolin Ye  Ciping Deng 《Psychology in the schools》2020,57(4):556-571

Rapid automatized naming (RAN) is associated with children's arithmetic performance, which is multifactorial by nature and consists of arithmetic fluency, arithmetic procedure, and word problems. Yet, it is unclear whether RAN can predict all key aspects of arithmetic skills independently and what cognitive mechanisms may explain this relation. Using a sample of Chinese primary school students (N = 170), results showed that while RAN was associated with all key aspects of arithmetic skills, the relations of RAN–arithmetic procedure and RAN–word problems may be dependent on that of RAN–arithmetic fluency. Supporting the processing speed hypothesis, results further suggested that processing speed may underlie the relation between RAN and arithmetic performance. Findings made unique contribution to understanding the effect of RAN on arithmetic performance and cognitive mechanisms that may underpin this association in the context of Chinese culture.  相似文献

动词make的一词多义关系模式初探     

房青 《牡丹江教育学院学报》2011,(2):38-39

一词多义是各种语言中普遍存在的现象。英语中除了术语以外,单义词是很少的,多数的词都是多义词。本文从认知语义学的视角,运用认知语言学的＂原型范畴理论＂以及＂基于理论的多义词分析法＂对动词make进行认知研究,探索构建make一词多义的意义关系模式。  相似文献
