充分挖掘例题的教学价值和开发功能

例题教学是数学课堂教学重要环节之一，通过例题，学生对所学的概念、定理、公式、法则、方法和思想等，可以获得更进一步的认识。同时，又可启迪学生思维，示范学生解题，培养学生能力。因此，在例题教学中，若能启发学生多用度、多层次、全方位地思考。对例题进行变式、探索、推广和引申，充分挖掘例题的潜在功能，必能更有效地开发学生智力，培养创新意识，提高解题水平，充分发挥例题的教学价值。本文以教材上的一道例题的教学为例，就此作点说明。

对课本例题教学的思考

重视教材例题的教学，要能从例题中提炼出一些重要的东西，如基本图形、基本思想方法等．通过例题教学来激活学生思维，深化对以例题为载体的知识、技能的理解．在长期的教学中，我总结出以下几点做法．     

引申课本例题，提高探索能力

课本中的例题具有典型性和示范性，正确引导学生对例题展开一些探究，适当引申拓展，有利于激发学生的学习兴趣，有利于提高学生的探索能力，有利于培养学生的发散思维和创造能力。     

谈数学例题、习题教学

例题、习题在初中数学中占有重要地位，它是联系基础知识和基本技能的桥梁，好的例题，不仅可以加深对定义、定理、概念和法则的理解，培养学生的解题技巧，而且可以加强对学生的思维训练，会极大地提高学生分析问题和解决问题的能力。     

在习题教学中进行科学方法的教育

习题教学，不仅要使学生对所学理论知识得到深刻理解，而且也要强化思维方法的培养。本文通过对典型例题的分析，巧选解法，较好突破了学生的思维定势，突出地培养了局部和整体思维、正反向思维、发散思维以及类比联想思维。

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.

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.
