浅论思想实验及其能力的培养

介绍了思想实验及其作用,分析了思想实验与实物实验的关系及思想实验的特点,探讨了培养思想实验能力的方法和途径     

浅谈高考物理实验能力的培养

历年高考十分重视物理实验能力的考查,对教材上规定的实验要求做到：明确实验目的,理解实验原理,会控制实验条件,会使用规定实验中学过的实验方法,会使用规定实验中所用的仪器,会观察、分析实验,会处理实验数据,并得出结论,会简单的误差分析。近几年,高考对实验的考查不再拘泥于教材中的规定实验,增加了设计实验方案的考查,增加了对于规定实验的迁移能力以及应变能力的考查,也增加了运用所学的实验方法解决一些新实验题的能力的考查。下面笔者谈谈实验教学中应注重培养的几种实验能力。     

虚拟实验的特点与实现

虚拟实验不仅仅是远程教育所必需的,对于全日制普通高校也是非常重要的。本文首先介绍了虚拟实验的必要性,然后讲述了虚拟实验的概念,并结合实践总结了虚拟实验的特点,重点研究了真实实验与虚拟实验的关系。采用虚拟实验能弥补传统真实实验存在的不足,符合实验教学改革的发展趋势和人才培养的实际需要。

漏洞百出的教育

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?     

只要努力,不要后悔

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.     

浅谈移民问题

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.     

Sister Carrie, an Adherent of Desires

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.

The Reader Response Approach to Teaching of English Literature

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.
