创新思维能力评价是属于"绿色指标"里学生学业水平指数中的学生高层次思维能力指数。在化学教学中,学生创新思维能力评价可分为认知目标和情意目标两个部分。我们在化学教学中应如何关注学生的高层次思维能力?如何对创造性思维能力进行评价?我校通过设计创新思维评价表,在化学教学中对学生的创新思维能力评价进行探索与实践。一、设计创新思维能力评价对于创新思维能力评价,我们认为,通过对创新思维的认知和情意目标中的各项行为特征进行列表 相似文献

化学是以实验为基础的学科,抓住实验教学方式的改革,就抓住了化学教学改革的关键和切入点。因而,化学实验教学的创新是推进化学教育改革的核心。中学实验教学的创新设计和改革应符合中学生年龄特征和认知水平,使中学生通过自身努力,能够完成实验的创新设计。化学实验方法的研究,有利于培养学生科学素质和科学理念,有利于学生掌握科学研究方法。学生科学理念的形成,是产生科技创新的萌芽,是产生科学研究兴趣和实现科学理想的种子。文章结合自身教学实践对初中化学实验改进与创新问题进行探讨。 相似文献

化学实验方案的设计贯穿于初中化学教学的全过程,而改进化学实验是培养学生创新思维能力和创新精神的有效途径。新教材在实验设置、实验内容、实验数量以及实验形式等方面有了很大的改变,实验教学也应随着新课程的实施进行相应的改革和创新。化学实验创新的方法很多,教师应该学会如何选择创新点,即学会从何处创新。 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

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

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

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
