广义Chaplygin气体与Chaplygin气体方程组Riemann问题解的比较

在给出Chaplygin气体方程组Riemann问题的解后求出广义Chaplygin气体方程组当α→1~-时的Riemann问题的解.根据相应的初始条件,广义Chaplygin气体方程组当α→1~-时的Riemann问题的解与Chaplygin气体方程组Riemann问题的解均由两个接触间断或者δ-激波组成.因此,当α→1~-时,广义Chaplygin气体方程组Riemann问题的解与Chaplygin气体方程组Riemann问题的解是一致的.

Cauchy—Riemann条件的复形式及其在教学中的应用

<正> 在复变函数的教学中,加强揭示复变函数与数学分析的内在联系,对于巩固数学分析知识与提高复变函数的教学质量有着十分重要的意义,而Cauchy—Riemann条件是解析函数f(z)与二元实函数u(x,y),v(x,y)联系的纽带,是解析函数教学中的重点,也是关键,我们在教学中引入了Cauchy—Riemann条件的复形式,建立了Green公式的复形式,从而将Cauchy定理、Cauchy公式与Green公式巧妙地联系起来,这样做,有利于开阔学生的视野,可以帮助学生更好地理解复变函数的基本理论和掌握复变函数论方法。

英语否定转移的表达方式及其汉译

否定转移是指位置上与一个词或短语放在一起的否定词,有时在意义上或逻辑上可转移到去否定另一个词或短语。通过总结英语否定转移的四种表达方式,即从一般否定转移到特指否定;从特指否定转移到一般否定;从一种特指否定转移到另一种特指否定;从否定主句谓语动词转移到否定从句谓语动词,来探讨其在汉语中的翻译,以期进一步提高翻译的准确性。

A Case Study of Preschool Children’s Musical Interests at Home and at School

In the interaction between the child and the adult, interest can be a significant motivational initiator of activities. Systematic monitoring and development of the interest in music activities enables the teachers to influence the preschool children in forming a positive attitude towards the art of music. The research involving preschool teachers, children at the age of five to six and their parents, was conducted in order to determine the interest of preschool teachers and children in music activities. We found that the teachers showed greatest interest in singing songs, playing instruments and listening to music. The children’s favourite activities in kindergarten were movement to music (dancing), singing songs and playing on instruments, namely activities where they could take active part in the educational process. The parents reported that at home the children preferred most to listen to music, to sing songs and move to the sounds of music, and less to play on instruments and to be creative in music. The development of the children’s interest in music depends on the teachers’ expression of interest in music activities, on the choice of music activities and music contents and on the experience in the music environment of the family.     

The Scientist as School Teacher

Many scientists, driven by the teaching impulse, idealism, or the wish to see science thrive in the United States, take up one or another form of school teaching or participate in programs designed to enhance science teachers' knowledge of science and science teaching skills. Funding is available, from governmental and private sources, to support innovative programs designed to increase the supply of well-trained science teachers. The provision of new funds to support graduate programs in fundamental science that provide a separate track for graduate students who choose a career in teaching, in preference to a career in the laboratory, is a particularly promising development. It is essential that such programs include proper training in pedagogy. Above all, the Nation must recognize the need to provide proper long-term salary support for science teachers in the public schools countrywide, if any of the programs to improve teaching is to succeed.     

Leaping Out of Our Skins: Postmodern considerations in use of an electronic whiteboard to foster critical engagement in early literacy lessons

Postmodern theory is used to consider literacy instruction with and without an electronic whiteboard to investigate what it means to move beyond using technology to replicate older models of classroom structure that may be historically situated but that also limit or at least, do not support engagement in ways that may be possible through use of new technologies. Using postmodern theory in this regard is a way in which to consider again the thoughts and practices that tend to construct identities and ideologies in ways that work against true engagement in literacy tasks, lead to subjection and demonstration of acquiescence in place of engagement that leads to participation and critical engagement. Critical engagement as opposed to gaining and maintaining student attention to task are considered in this paper. Thinking about use of the electronic whiteboard from a postmodern perspective cautions us about careful use of this technology to avoid sending messages to students about them and their role in literacy development, the classroom, and in society.     

从新托福考试看英语听力训练

即将于2D04年正式开始的新托福考试目前已经通过美国KIS中心设计的“LanguEdge”(锋利英语)教程中的考题模型呈现出来，新托福的宗旨基本上是对听、说、读、写综合应用能力的真正考查。新托福试题的内容和题型变得更加贴近北美大学学习和生活的实用需求。相对于旧托福而言，新托福明显增加了我国众多考生明显薄弱的听、说两个环节。新托福不仅将会给中国的英语教学带来一个新的冲击，促进我国英语教学的改革，而且还会给我们的听力教学带来不少有益的启示。     

What successful black South African students consider as factors of their success

Black South African students have a poor success rate in school leaving mathematics examinations. Attempts have been made to shift teachers' practices from teacher-centredness to learner-centredness, in Black schools, in order to improve the situation. So far, the attempts failed to yield the desired results. This paper reports on the findings of a study that aimed at learning from students and teachers in Black schools, as to what classroom practices lead to success in school mathematics, in their impoverished context.This revised version was published online in October 2005 with corrections to the Cover Date.
