浅谈如何利用和化解“错误”

在我们的课堂教学中,每天都有学生“出错”,学生的学习错误,是学习过程中常见的现象,学生在学习中出现错误和误解,有助于教师确定学生在学习方面存在问题的类型。教师只有弄清这一点,才能很好地做出教学计划,便于帮助学生消除错误。错误和误解都是基于不适当的理解,学生在学习中产生的错误,对激发学生对所学材料的兴趣,唤起学生的求知欲望有特殊的作用。教师通过与学生讨论错误,使他们看到错误所在之处以及错误的原因,可以有效地消除错误,而且能使学生加强对数学的理解。     

高中学生化学学习错误的类型及有效利用教学策略

针对因教师对学生学习错误片面认识所造成的教师和学生害怕或躲避学生学习错误、课堂上“虚假正确”广泛存在的现象,从高中化学教学的角度出发,将化学学习错误分为概念性错误、思维方法性错误、实验操作性错误三类,并分析了有效利用学生学习错误的三个前提:树立正确的学习错误观、形成“错误资源”意识、遵守利用学习错误“三原则”等,在此基础上分别从教学情境设计阶段、重难点讲解阶段和知识应用阶段提出有效利用学习错误的教学建议。     

错误资源在数学课堂教学中的有效应用

学生在学习数学时经常出错,这是个正常现象。所以,教师应更多地分析课堂中学生的错误,挖掘和利用学习错误,努力从学生发生错误的角度去解读学生,了解学生错误背后的学习障碍,帮助学生理清问题背后的障碍,使学生真正理解知识,掌握知识。这有利于激发学生学习兴趣,增强学生自信心,还可以有效培养学生的创造性思维,使学习错误变错为宝;改变教师对学生错误的不正确观念和处理态度,锻炼教师的教学机智。     

找准错误成因,打造高效课堂

在学习过程中,每个学生都会犯错,教师应按不同的错误类型进行区分指导,帮助学生尽快走出误区。对知识认知错误、逻辑错误和概念错误三种错误类型进行分析,以期减少学生错误,提高学习效率。     

浚错误之源,正教学之流——浅析小学生学习错误的成因及教学借鉴

数学学习中,学生经常和错误打交道.但错误并不可怕,它是学生学习活动过程中主动思维产生的结果之一,是学生经历了分析、对比、理解、调整等学习方式后对问题的一种反馈.面对学生各种各样的错误,教师应该冷静对待.本文透过现象,从学生思维、数学本质、学习习惯、审题能力等方面对学生的学习错误做了粗浅的分析.     

让“错误“为课堂增添生机与活力——例谈对学生“错误“的有效利用

“错误“是学生学习中的宝贵经历,也是教学中的宝贵资源.教师要理性面对学生学习中的错误,对之有效利用,从而促进学生发展.有错误的课堂是真实的课堂,直面错误的探求活动是最有价值的学习活动.课堂因“错误“而更有活力!     

对学生解题错误的探析及应对方法

<正>在学习过程中,错误的出现是不可避免的,因此对错误产生的原因进行分析是非常重要的:首先错误能给教师一个信息,可以通过错误发现学生学习的不足,从而采取相应的补救措施;其次,错误从一个特定的角度提示了学生掌握知识的过程;最后,错误对于学生来说是不可或缺的,是学生在学习过程中对所学知识不断尝试的结果.下面就学生解题错误的原因作探讨.一、学生解题错误产生的原因学生能否顺利地完成解题,主要取决于其在分析问题,提     

让“错误”成为催化学生生命的精彩

在小学数学教学中,"错误"总是和学生的学习相伴,如影随形。如何认识学生学习中的错误?是把它看作垃圾,还是看作可贵的学习资源?本文从新课程理论的角度,来认识学生学习中"错误"的价值,将"错误"视为优质的学习资源,探讨在课堂中"错误"资源利用的方法和策略,通过对"错误"资源的开发、研究     

初探初中学生数学解题误区

在数学学习过程中,错误的出现是不可避免的因此教师对学生出现的错误进行系统的分析是非常重要的首先教师可以通过学生出现的错误来发现学生的不足,从而采取相应的补救措施;其次,错误从一个特定的角度揭示了学生掌握知识的过程;最后,错误对于学生来说也是不可或缺的,是学生在学习过程中对所学知识不断尝试的结果.本文就初中学生在数学学习中出现的解题错误作一简要分析.     

小学数学教学中“错误资源”的巧妙运用

随着新一轮基础教育课程改革的深入,人们对学生的学习错误有了更深的认识。目前达成的共识是,要充分挖掘学生错误的价值,用资源的眼光看待错误,并巧妙运用学生的"错误资源",使其从错误中加深对所学知识的理解,并不断开阔学习思路,提高学习效率。

Western and Eastern culture differences in commercial field

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.

漏洞百出的教育

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?     

只要努力,不要后悔

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.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.

团图为数的图中的闭团贯数

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.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
