课堂教学作为教和学在动态中的组合,其中包括了多种复杂的要素。在教学实践中,课堂教学的优化主要是使教和学的各个方面在动态中的组合形式具有高度的和谐性,以充分发挥教师的作用。教学实践中,笔者从几个方面对物理课堂教学的优化组合进行探讨。 相似文献

现代教学理论倡导实现教学过程中学习方式与教学方式的转变;中职德育课程教学必须积极实现“两个方式”的转变;必须重视通过教师的启发引导、点拨指导、因势利导、分层辅导来顺应教学方式转变后教师的“教”;必须重视通过学生对教学过程中的参与及学会发现、学会运用、学会创新来顺应学习方式转变后学生的“学”;“两个方式”转变后必须实现“学”与“教”的最佳组合。 相似文献

<正>排列和组合是组合学中最基本的概念,也是数学解题中的重要方法之一。在数学解题和实际生活中,排列和组合思想都有着广泛的应用,在小学数学中渗透排列组合的思想,对培养学生的数学思维和解决问题的实际能力,发展小学生抽象思维和逻辑思维能力有着重要的意义。一、排列思想在小学数学中的运用 相似文献

教学是一门艺术,它是由教师的教和学生的学两个因素组合成的交响乐。优化教学过程就是要让教与学这两个因素更自然、更科学的组合起来,使“教”吸引“学”,“学”促进“教”,达到一种教学上的美的境界。优化教学过程需做很多工作,但我认为特别应注意以下三点: 一、要重视教学中的引导。学生注意力的集中与否是教学成败的标志之一,学生的大脑是一部精密的信号接收器,课 相似文献

在我国其它省市实验区科学课程面对综合还是分科选择的难题之时,浙江省的科学课程改革与实施坚持着“综合”的导向,因而审视与反思浙江省综合科学课程推进中的问题成为必要。本文基于科学课程实施现状的调研、七个维度三个层次设计的访谈、对典型地区学校的课堂观察,提出浙江省综合科学课程推进中的问题,表现为“综合科学”与“组合科学”两种科学课程形态的并存;科学教师对科学课程性质与目标认识不到位;对课程资源理解不一,科学教材之外的课程资源开发不足;有效科学教学方式与方法的使用亟待专业引领。进而立足于综合科学课程实施中的难点,提出有效推进科学课程实施的根本在于以培养与培训相结合促进科学教师专业发展;以教材比较研究促进科学教材的完善;改革中考,促进科学教师对科学教学评价的探索。 相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity. 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F. 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language. 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献
