教学语言艺术初探

教学语言是指教师在传授科学文化知识、开发学生智力、培养学生能力,进行思想品德教育过程中所使用的一种专业语言.它受教育工作任务、性质和特点的制约,是多种语言风格的融汇,是科学性、教育性、艺术性的有机统一.教学语言具有科学性、规范性、教育性、针对性、激励性等基本特征,教师在正确掌握其基本特征的基础上还必须具备情感性、直观性、幽默性、启发性、通俗性、审美性、自控性、个性化等进一步的要求.     

为科学奋斗终生的伽利略

1564年2月15日。伽利略出生在意大利的比萨城。他父亲是一位有才华的音乐家,但他从小就对数学和物理学感兴趣。在中学时期,伽利略就决心终生献身于科学事业,准备到大学里学习数学。但是,在那不讲科学的年代里,这一行意味着一辈子的贫困和默默无闻。因此,父亲反对他学习数学,准备叫他做一个服装商人。伽利略坚决不同意。父子两人经过妥协,1581年,伽利略进入比萨大学学医。     

论全面建设小康社会的重点和基本思路

全面建设小康社会是跨入新世纪后全国各族人民的奋斗目标。全面建设小康社会的内涵可以从时间、空间和质量三个层面上来界定。其建设重点应该体现在农村、农民工作中,体现在西部大开发的战略中,体现在扶贫开发、城镇化建设和可持续发展的过程中。为此,须明确今后主要工作的思路。     

Dependence of nucleotide physical properties on their placement in codons and determinative degree

INTRODUCTION It is well-known from the genetic code structure that there exists a connection between codons and physical and chemical amino acid properties (Lewin, 1983). Codon properties in turn are defined by physical properties of the nucleotides from which they are compounded (Ratner, 1985; 2000). The most important properties of nucleotides as complex three-dimensional molecules are their dipole moment, heat of formation and energy of the most stable con- formation (Schneider and Be…

A quantitative analysis of moral exemplars presented in moral education textbooks in Korea and Japan

This study is a comparative analysis of the characteristics of moral exemplars presented in moral education textbooks in Korea and Japan. The purpose of the study is to examine and compare moral values presented through the lives and stories of moral exemplars in the two countries that have moral education as an independent and separate subject based on the national curriculum. To this end, the study uses analytical criteria such as gender, nationality, social roles, historical backgrounds, and specific moral values in order to investigate characteristics of 307 moral exemplars in Korea’s and Japan’s most used moral education textbooks. The results show significant similarities and differences in moral exemplars between the two nations. In the case of the similarities, both countries emphasize moral autonomy and respect for human life. In the case of the differences, while Korea presents more historic figures as moral exemplars, Japan presents more students and ordinary people as moral exemplars.

On group and phase velocities manifested through exact solutions to the equations of some propagation phenomena

A system of non-Hermite, non-orthogonal functions that are new for concrete applications is introduced to generate explicit and previously unknown, physically meaningful solutions for bar and plate equations. The approach allows in some cases to establish completeness of these sets of solutions. Various other separate results technically related to these basic development are presented. In the available literature there are no registered efforts to extract the two velocities from exact solutions of the equations of the processes in which the two parameters are explicitly present.
