化学实验课是普通高校化学教育专业必修课程.如何通过无机化学实验课程的教学,激发学生的学习兴趣,培养他们的独立实验工作能力,有效地发展教育对象的素质,是实验教学中的一个关键问题.因此.就无机化学实验室的布置、实验课的讲解艺术、实验中的教学指导、实行开放性教学及以科研带动教学等方面提出了一些具体方法. 相似文献

通过无机化学实验教学,学生不仅要掌握基本实验操作技能和化学知识,而且要使学生发展智力,培养分析问题的能力;培养创造精神和良好的实验室工作习惯和素质;初步学会运用科学实验的方法,验证和探索化学变化的规律。为了加强和改进中学教师进修化学专业的无机化学实验教学,提高教学质量,需要改革课程设置,更新教学内容。一、改革课程设置,将无机化学实验单独设课独立设课的无机化学实验与从属于理论课的无机化学实验,两者之间有什么差别？怎样在教学和教材中体现无机化学实验课的独立性？我认为首先从教学计划上要肯定实验课的地位… 相似文献

基础无机化学实验是各专业实验课程的基础．通过这门实验课培养学生良好的实验习惯,训练扎实的基本功．有助于后续各种实验的顺利进行。由于目前高考制度的改革,学生的化学实验水平良莠不齐。大班化的实验教学明显不利于对学生的单独指导,学生独立操作和思考的机会较少。改为小班化实验教学后,学校的实验资源得以充分利用;增加了教师对学生实验指导的时间;培养了学生在实验课程中独立思考的良好习惯等。可以看出小班化基础无机化学实验教学更加充分地发挥了该课程应有的教学目的。为学生今后四年的化学实验课打下了坚实的基础。 相似文献

化学是一门实验科学。无机化学实验是师专化学专业第一门独立开设的基础实验课,是整个化学实验的起点和基石。它对于开发学生的各种能力,培养严谨的科学态度和实事求是的科学精神至关重要。它不仅和无机化学理论课有广泛紧密的联系,同时又是后续实验课的基础。因此,它在化学教学的全过程中占有十分重要的地位。为了不断地提高无机化学实验教学水平,几年来我们做了一些尝试: 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

Migration occurs behind a variety of reasons and has a great effect on the whole world. 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

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

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
