我们两年来在利用学校多媒体网络进行现代化教育技术的应用方面、作了一些有益的探索。一、我们在课堂上采用了新型的教学方法所谓开放型教学、开放型试题、开放型教案、开放型练习,不同于传统的开放型数学问题。在传统的开放型数学问题的理解上,大多把一些数学问题求解的多样性、答案的不定性作为开放型的问题。而在这里的开放型教学,我们借鉴国家改革开放的思路,把教学的教案、教学过程、教学方法、数学思想、国际数学问题等都在Internet国际互联网上开放,使学校的围墙、教室的大小、时空的限制成为不能制约的因素。我们在教学设计上,以… 相似文献

专题说明探索型问题和开放型问题的设置常常是一套中考试卷中的亮点,也是衡量试题是否具备创新意识的必备条件之一.中考试卷中往往会出现一两道探索型和开放型的题目.另外探索型和开放型问题对于培养同学们创新精神、提高实践能力也起着重要的作用.探索型问题和开放型问题之间往往没有一条明显的界限,它们二者均具有题目的条件不完备或者结论不 相似文献

随着新课程标准的深入实施，近年来的中考数学试题中出现了越来越多的开放性问题。所谓开放性数学问题，是指那些条件不完备，结论不确定的数学问题。开放性问题重在开发思维，促进创新，提高数学素养。在中考试题中常见的开放性问题主要有条件开放型、结论开放型、组合开放型和策略开放型等几种，本文试就其解题思路举例予以说明，供参考。 相似文献

开放型题就是没有完备的条件，没有固定的方法．而且答案也不是唯一的。开放型题按创设问题情景的不同，可分为：应用开放型题、策略开放型题、变式开放型题。解答此类问题时，必须对研究对象可能的物理状态，可能发生的物理过程或现象进行判断、讨论，才能得出最终结果。[第一段] 相似文献

开放型问题也称探索性问题,它与传统题型不同,开放型问题可能条件不够完备,结论也可不一定唯一确定,具有开放性,解题的过程具有探索性,对培养学生独立解决问题的能力,自觉参与科学发现有重要的意义。本文就“开放型问题”解题的一些思路进行了一些探讨。 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

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

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

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

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
