省编一九八○年高考化学复习资料的实验部份,“增加了化学实验的基础知识,加强了对学生实验技能的训练”,但“由于篇幅的限制”,提供师生复习与训练的实验题目还不够充分。据此,笔者收集和选编了下列基本操作题和综合实验习题,供即将进行化学实验复习的同行们参考,并祈批评指正。 相似文献

高考化学当中的实验题着重考查了学生的综合能力,学生往往难以把握,是比较容易丢失的题型。化学实验题在高考前的复习当中,从化学实验基本原理的领会到化学基本技能的掌握,逐步培养学生创新的意识,对专题复习进行强化,还要不断加强答题规范化的训练,从而将化学实验题的得分率提高,并让学生逐步养成严谨而细致的学习作风。 相似文献

在高三化学总复习过程中，对每一重要知识点，需精选不同层次的题目，由易到难，编成题组，学生在解题时，思考坡度循序渐进，每解完一组题，都能亲自体会出其中蕴含的规律，领略到命题的意图，这样既培养了学生的思维能力，又提高了复习效率，收到了良好的效果．笔者以有关“水的电离”这一知识点为例，设计了以下题组，对学生实施训练． 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

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

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

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context. 相似文献
