影响学前儿童图画书自主阅读的因素——来自眼动的证据北大核心CSSCI

以61名5-6岁儿童为被试,采用TobiiT60眼动仪,本研究对学前儿童在自主阅读图画书过程中的文字注视情况进行实时记录与分析,结果发现学前儿童自主阅读图画书的能力随年龄增长而发展;接受性语言能力、识字量水平、生字量水平与文字注视水平存在显著相关,其中生字量水平即文字再认能力是影响学前儿童自主阅读图画书文字注视的核心因素。     

"光合作用"插图的教学探讨

学生对光合作用的过程不易理解掌握 ,课本的插图使其形象、直观 ,但往往容易被学生忽略 ,用好这个插图 ,既可以帮助学生理解课本 ,又可以提高识图能力和本节知识的迁移能力。1　对插图的阅读和知识的突破1.1　配合文字内容 ,阅读插图 ,提高文字表述的能力　图 1是课本光合作用过程插图 ,此图从整体而言 ,是光合作用的全过程 ,从局部看分为光反应和暗反应两个阶段 ,每个阶段都包含很多个化学反应。图中共有两个圆、10个箭头。教学中 ,我利用插图进行文字的讲解。光反应是在叶绿体内的囊状结构上进行的 ,叶绿体的色素吸收光能 ,一方面将水分解…     

试论分析学生学业失败时的归因偏差问题

归因理论是社会心理学关于人们对社会行为原因推论的一个研究领域。它研究人们如何理解、解释行为,是社会心理学研究的重要课题。在教育实践中,归因理论也有很大的用途,如用在对学业成绩的归因分析上。由于种种原因,有的教师在对学生学业成绩的归因过程中存在一些不合逻辑的非理性现象,没能准确找出影响学生学业成绩的主要因素,而出现归因偏差,且这种情况在分析学业失败时更为明显。本文试就教师在分析学生学业失败时所出现的归因偏差问题(以下简称归因偏差)进行讨论,以引起人们对这一问题的关注。     

个体化目标结构下小学生学业成绩影响因素的研究

在个体化目标结构下,以小学五年级学生为被试,考察了个体化目标公开范围、性别和认知方式对学业成绩的影响。结果表明:(1)制定个体化目标后,学业成绩进步显著,显著程度因被试变量的不同而不同;(2)个体化目标公开范围影响成绩进步的幅度;(3)个体化目标公开范围与两个被试变量存在交互作用。     

初中历史课的插图教学

初中历史课本中配有较多的历史插图,如图表、彩图和历史地图等,目的是增强教学的直观性,激发学生的学习兴趣。在教学中如何认识并运用好这些插图呢？图文并茂的历史课本令学生喜爱,书中的插图可以吸引学生,也可以帮助他们理解那些仅靠文字难以描述的历史知识。比如：...     

中学生物学教科书插图比较研究

文字和图像都是记录人类历史、表达世界的手段。文字和 插图被广泛地应用到需要记录的各个领域。生物学中的生命 现象涉及大量的微观现象、过程和机理,仅凭语言文字难以描 述,这时教师结合插图教学有利于学生分析微观现象、过程及 生命活动机理,帮助学生理解抽象的生物学概念及原理。     

对初中化学新教材中插图的认识

教材中的插图,辅助文字形象生动地展示、解释知识,促进学生对新知识的理解;初中化学教材中的插图是新教材中的一个亮点,插图与课文文字的合理搭配,使教材在视觉上显得图文并茂,符合初中生的年龄特征和认知规律。教师应很好的认识教材中插图的作用,发挥其独特的教育功能。     

谈地理课本的插图教学——以北美洲概述中的四幅插图为例

课本插图不同于教学插图,学生人手一册,使用起来,十分方便。一幅好的插图,可以充实课本有关内容的文字叙述,加强教材的说服力,有益于学生对知识的理解。面对繁多的课本插图,教师在教学中应注意归类、分清主次,并逐步培养学生通过各种“图”综合分析地理事物的能力。世界地理下册第六章概述中的四幅主要插图,我在教学中是这样运用的:     

改变教材插图提高教学有效性的尝试

为利于学生记忆和理解,尝试对高中生物学教材中的部分插图的内容或者文字作了改变。     

论插图在高中历史教学中的独特作用

插图是高中历史教材的重要内容,由于高中历史信息量大、内容繁杂,单靠文字叙述以及史料佐证,难以将特定的历史现象直观地表现出来,从而影响提高教学的效果.而插图的使用则将复杂的历史信息形象、生动、直观地表达出来,同时,插图与文字相结合,更有利于学生对历史知识的理解与掌握.高中历史插图的独特作用主要体现在如下几个方面.     

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.

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.

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?     

Social and Cultural Influence on Word Meaning

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.     

汉字倒说

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。     

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.
