一般地说,分数除以整数的计算法则,学生较易理解,而对于一个数除以分数的计算法则,多数学生感到抽象难懂。怎样来推导一个数除以分数的计算法则,才能使学生比较容易理解并掌握它呢?这里,笔者提出一个教学设想。 相似文献

文章从爱因斯坦对法则性理论的定义为基础来解释波函数,力求阐明在玻姆隐变量语境下,波函数可以被看作是一个法则,并分析了把波函数看作法则可能遇到的困境及解决方式,从而更充分地说明波函数的意义,指出作为法则的波函数是我们在特定语境下理解物理学理论的一个新平台。 相似文献

一、对应与对应思想 "对应":对于给定的集合A和B,如果存在一个法则f,对于集合A的任意一个元素a,根据法则f,得到集合B中的元素b,那么就把这个法则f叫做从A到B的一个对应,记为f:a→b=f(a).例如,下面表示一个对应. 相似文献

平行四边形法则是一切矢量合成的普遍法则,在许多矢量合成与分解的问题中,尤其是一些动态变化的问题,应用平行四边形法则导出的矢量三角形法则进行分析求解就显得很方便快捷。虽然教材中没有介绍矢量三角形法则,我认为,教学中应将它传授给学生。其矢量三角形法则是:如图(一)所示,根据矢量可平移的性质,在失量合成的平行四边形中将其中一个分矢量F2平移后,就与另一个分矢量F1和合矢量F组成矢量三角形。其合矢量与分矢量的关系是:两个分矢量首尾相接,分矢量与合矢量首首相接,尾尾相接,这就是三角形法则。下面就一些具体例子谈谈矢量三角形法则的应用。 相似文献

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. 相似文献

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. 相似文献

As a result of reported failings in the care of people in the health and social care sector in the UK, HE providers who produce professionals to work in these areas are being challenged to address caring values in the student body. As values are subjective and affective, this requires the learning environment to not only promote critical thinking and the development of professional competencies, but to facilitate personal growth and change within students at cognitive, emotional and spiritual levels. As the latter dimensions are frequently ignored in education, this is very challenging: it requires a curriculum that supports students to understand, reflect on and, if necessary, restructure their own caring values in order to develop a transcendent lens i.e. the ability to put others before their own self interests and that of the organisation in which they work. It also requires students to develop the skills to challenge others in situations where caring values are not achieved or sustained. This can only be accomplished as a co-produced phenomenon, as it requires students who are prepared to engage in the process and educators, in both HE and practice settings, who are able and willing to role model appropriate skills and facilitate a learning relationship in which students can grow. However, if the true wisdom of caring values is to be realised in everyday practice, then this kind of transformational learning has to be supported at wider structural levels, and this just may be its Achilles heel. 相似文献

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. 相似文献

在普通话教学与培训中,众多教师和学习者探索出了很多语言因素训练的好方法,如发音训练,正音训练等等,但是在实践中我们发现,仅仅加强语言因素的训练是远远不够的,还必须加强语言因素以外的能力和素质的训练,才能全面提高一个人的普通话水平。本文试着从教学和测试中常见的现象进行分析和探讨,提出在教学训练中应加强思维、阅读、兴趣、心理等非语言因素的指导,更有效地提高学生的普通话水平。 相似文献

这里以郁达夫与李商隐为个案,考察“五四”作家的旧诗创作对古代作家的承继关系,以探究异代诗人的诗性人生。一从诗艺的比较揭示千年一脉的悲剧精神．二人诗作的设色、结构、造境都呈现感伤的美学特质,不同在于郁诗以旷放排遣感伤,李诗以执着郁结感伤．二从政治态度的比较揭示人命运无法摆脱政治的影响．二人都有政治热情,不同在于李希望跻身政治而不被接受;郁自疏于政治,却因国族危亡不得不与之产生瓜葛。三从性苦闷宣泄方式的比较揭示人格结构的多面性．李宣泄在诗歌中,突破诗庄词艳的分工;郁宣泄在小说中,身为“五四”先锋却恪守温柔敦厚的诗教． 相似文献

中国近代大学校长与自由主义教育 总被引：4，自引：0，他引：4
20世纪初 ,由于受西方自由主义思潮的影响 ,加之部分著名大学校长的身体力行 ,中国近代大学教育逐渐滋长了一种自由主义教育的倾向。这种倾向 ,在教育目的上崇尚个性主义 ,在教育过程上坚持学术自由 ,在教育管理上力求教授治校。它反对封建教育对个人发展的专制 ,具有进步意义。但是 ,由于它生不逢时 ,加之其本身的软弱性 ,因此在半封建半殖民地社会条件下 ,它也就不可避免其最终的失败命运 相似文献

电子琴教学中，尽快提高学生的演奏水平的最好方法就是重视和加强学生电子琴基本功的训练，作为一名电子琴教师，要想教好一件乐器首先必须对这件乐器的发展原理，构造，特点及与相近乐器有一定的研究和了解。基本功训练的要求主要是以下两个方面，首先要求头脑清醒，抛开一切杂念，全身心投入，领会乐曲的旋律，意境，让乐曲的每个音筏，乐句在自己手指，手腕，手臂的每一个细微动作的配合上找到最好的感觉，其次，在理解作者的创作乐曲的创作意图的同时，对特殊意句，乐段进行重点练习。 相似文献
