引导小学生在多向互动中学习数学

现代教学理论认为,教学是教师的教与学生的学的统一。这种统一的实质是交往,这种统一的方式是互动。也就是,教学过程是师生交往,积极互动,共同发展的过程。现代教学论还进一步关注到,教学过程不仅只有师生两个因素在互动,当今学校教学过程是在班级授课制的环境下进行的,师生的互动离不开教学所需的环境,学生互动的对象不仅指向教师,还指向环境,更指向班级中的同伴。     

网络教学环境下情感交流问题探析

网络教学环境下由于教师和学生、学生和学生之间处于准分离状态,导致师生信息交流残缺不全,进而影响到学习者的情感发展.应在对目前网络教学环境进行分析的基础上,加强网络教学的情感化设计,并通过一系列有效措施解决网络教学环境下存在的问题,促进学生情感的交往.     

基于教学平等的网络课程设计要素与原则

现代课程论和教学理论把师生间的交往活动——教学活动置于课程中的重要位置，开放教育中的网络课程尤为注重教学平等的教学效果。本文依据现代课程论和教学论的核心观点。对网络课程设计应该关注的主要因素包括课程内容、内容的结构和呈现方式、学习者的经验。以及课程教学环境的营建进行了初步分析，并据此提出了网络课程设计的一般性原则：整合性。互动性，生成性，发展性，可选择性，亲和性。     

对话交往式教学资源的开发

教师自身丰富的思维方式、价值观念、教育思想、知识修养、教育教学技术等,都是重要的教学资源。在核心教学、协商教学过程中蕴含着对话交往式教学资源开发的有效方式。学生是课堂教学中最有潜在价值的主体性因素,也是对话交往式教学资源的开发者。网络教学环境为教师和学生提供了最为便利的对话交往空间。同时,在网络环境中,教学资源不仅仅以文本的形式呈现,师生间、生生间的交往对话往往可以留有记录。教师在教学过程中,随时可以对教学资源进行填充或改良,学生也可以不断从中获取新的体验、新的信息及感悟。     

网络环境中的教学交往

交往理论目前已经成为国内外的“理论热点”之一,对于教学交往的研究是当前教育领域中的热点课题。本文从信息科学和传播学的角度出发,论述了网络环境下的教学交往,着重论述了网络环境中教学交往的主体及其特性、教学交往的特征和教学交往的设计等问题。     

网络环境下的教学交互

远程教育是信息技术介入教育交往的教育形态。新信息技术延伸人类交往,构建虚拟交往的代表是网络环境。本文通过教学交互分类,交互与教学模式,网络环境下交互需要、交互方式、交互水平等要点阐述,探讨了网络教学中以个别化交互为主的自学习模式。     

在互动中学习 在学习中育人

在传统的“课程即知识”的影响下,教学过程被认为主要是传授知识,鼓励学生模仿记忆的,以教师为中心的固定的教学步骤。而现代教学论指出,教学过程是师生交往、积极互动、共同发展、教学相长的过程。没有交往,没有互动,就不存在或者未发生教学。在新课程理念的背景下,传统意义上的教与学,将不断让位于师生互教互学,彼此间将形成一个真正的“学习共同体”。在这个共同体中,教学不再是教师主导的独角戏,而是师生间以交流、对话、合作为基础,进行文化传承和创新的特殊交往活动。就思想政治而言,     

提高教师的信息素质适应网络教学的对策研究

教师的信息素质是适应网络教学带来变化的基础素质。可持续地提高教师的信息素质不仅是当务之急,更是网络教学长远发展的需要。提高教师信息素质,适应网络教学的基本途径是：教师积极地融入网络环境;做好教师的信息化准备;学校营造一个良好的信息资源使用环境;社会参与网络教学社区建设。     

从角色转变谈网络教师的网络素养

网络教学发生在计算机网络构建的虚拟教学环境中,和传统教师相比,网络教师的角色定位及相应的教学行为发生了明显的变化。网络教师应具备全面的网络素养以适应这种角色转变,更好地实施网络教学行为。网络教师的网络素养主要由网络意识、技术、信息、交往和教学素养等内涵构成。     

对新课程背景下师生关系的新认识

现代教学论指出,教学过程是师生交往、积极互动、共同发展的过程。师生交往是否有利于学生发展是教学过程能否按照新课程标准来运行的前提和保证。交往的本质属性是主体性,交往论承认教师与学生都是教学过程中的主体,都是具有独立人格的人,两者在人格上完全平等,即师生之间只有     

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.

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.
