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

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

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

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

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

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

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. 相似文献

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. 相似文献
