通过文献资料法、问卷调查法、教学实验法等,对普通大学生采用不同练习方式学习乒乓球发球技术的掌握程度进行研究.结果表明:在一定负荷强度范围内,进行等量负荷控制的不同练习方式,在技能学习的初始阶段,"分散练习"的方式较"集中练习"效果好,而在后期则相反;在进行相同负荷练习时,女生对技能动作的学习掌握能力比男生强.因此,对普通大学生进行乒乓球发球技术的教学时,应根据不同阶段、不同对象采取不同的练习方式,提高其学习效果. 相似文献

因为语文教学多年来受到传统教学观念的制约,加之对语文学科教学理解的偏差,"精讲多练"的改革步履艰难,其中对学生练习分层、分阶段实施认识不清也是主要原因之一。随着语文教学的有效推进,"目标领航,练习开道"是语文教学的必然趋势。练习开道要做好:前置性练习的设计和使用、过程性练习的设计和使用、检测性练习的设计和使用、发展性练习的设计和使用,使练习贯彻课堂教学的始终,成为推进教学的有效手段。 相似文献

<正>小学数学练习的任务是巩固数学基础知识、形成解题技能技巧和培养学生运用所学知识解决实际问题的能力。如何设计数学练习,才能让学生学得既轻松愉快又能获得切实的数学知识、形成数学技能呢?我想根据小学数学学科的特点,针对目前数学练习设计中存在的倾向性问题,谈一些认识和做法。一、练习设计要有针对性练习课要有明确的教学目标,最忌无的放矢,为练习而练习,甚至炮制"题海"。教师一要深入钻研课标确定的本阶段教材的知识点、重点和难点;二要深 相似文献

练习课应该遵循学生的认知规律,适当地运用基本练习、变式练习、改错练习、开放性练习等,让学生从＂会＂过渡到＂熟＂,通过综合练习提高能力,使学生进一步由＂熟＂过渡到＂活＂。如果教师能精心设计每一节练习课的练习题,那么练习课的教学就能取得事半功倍的效果。 相似文献

练习是帮助学生掌握知识的有效手段,在每个阶段的教学中练习都发挥着重要的作用。练习对小学生的数学学习同样具有重要的意义和作用。结合实践教学情况来看,部分小学数学教师还没有充分认识到练习的功能和价值,缺乏对学生练习的关注与重视,在课堂教学活动中过分地强调教师的讲解而忽视了学生的练习,缺乏练习课程,简单地将作业当作学生练习的唯一途径,最终难以全面发挥练习的价值。基于此,本文将围绕如何发挥练习在小学数学教学中的作用展开探讨与分析。 相似文献

初中阶段是学生逐渐形成三观的重要阶段,在这个阶段,学生的知识储备得到了一定程度的提升,对问题的认识也较小学阶段有所深化,更重要的是孩子在这个阶段开始学会如何学习。如今的孩子基本上从幼儿园阶段就开始进行写字练习,随着孩子逐渐成长,练字逐渐成为一门必修课,那么在初中阶段的书法练习就变得非常必要。主要围绕初中书法教学探讨教师在教学生书法的过程中应该在怎样的方法指导下进行。主要分为四个部分。第一部分探讨重视书法练习的意义;第二部分为持之以恒地练习;第三部分着重讲述如何在练习中学会悟;最后为结论部分,总结文章,提出见解。 相似文献

多练习是否一定能改善学生的学习效果?对此许多教师深信不疑。但事实上熟未必能生巧,成功的练习是需要条件的,只有满足这些条件才能使练习真正发挥其作用。本文从教学实际出发探讨了教学过程中如何正确运用练习的问题。 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

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
