正基于教学的生成性,教学的有效性应当体现在教学过程本身是一个不断发生、生长、演化的过程。教学应当秉持以学生的生成性思维为核心的思维方式,探讨和追求教学生成,并通过教学促进人的文化生成。具体到图形教学的有效性问题上,我们可以从以下几个方面思考。一、抽象概括,生成图形概念图形是什么?在数学的世界里,图形不是客观存在的物体,不是具体的东西,它是人们抽象的结果,是人们摒弃了物体的颜色、重量、分子构成等物质属性,只从形状、位置、角度等 相似文献

核心图形和徽标是大型企业或重要活动的视觉识别系统中的两大核心要素。主要探讨核心图形的系统化设计以及生成方式,指出核心图形的系统化生成主要有“对完整图形的解构、单元形的强调和重复、灵活地模块组合”这三种方式,通过这项研究,有利于在纷繁复杂的视觉环境中建构清晰的信息体系。 相似文献

从认知语言学的图形─背景理论出发,英语名动转用应是这样一种机制:使用者把认知结构“图形─背景”转化为“背景─图形”。这一认知过程在语言中的现实化就是使用者将“原生名词的意象(图形)─生成动词和其它相关知识的意象(背景)”转化为“生成动词的意象(图形)─原生名词和其它相关知识的意象(背景)”。 相似文献

从认知语言学中的图形-背景论出发,重新审视成语仿拟广告词,分析其生成的认知本质,即成语仿拟广告词的生成是在认知参照点作用下择取本体背景和确定仿体图形的认知过程,从而扩展了图形-背景论对语言现象的解释力,同时也丰富了对这一语言现象的研究。 相似文献

针对制鞋行业中鞋帮缝制自动化水平不高的问题,提出了一种实现由图像格式到图形格式转化,再由图形格式文件生成数控代码的方法。该方法利用摄像机拍摄鞋帮面图像,经图像处理且运用矢量化算法可实现图像到图形的转换,形成的图形文件经过轮廓偏置处理及后置处理之后生成NC代码,并给出了一个应用实例。 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

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

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

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献
