发挥好“思考·练习”的作用

“思考&#183;练习”是课文的一个重要组成部分。一般课文的“思考&#183;练习”都有３─６个题目。思考题侧重于提示理解课文的思路并注意和本组的重点训练项目相呼应;练习题侧重于引导对课文中重点词、句、段的理解和体会,对生字词的巩固和运用。 按习惯的教学方法,一篇讲读课文,首先是扫清生字词,接着是按次序逐词逐句甚至是逐字分析课文内容、情节,最后才是让学生动笔做“思考&#183;练习”。然而有的“分析”超过时限,只得让学生把“思考&#183;练习”当作“家庭作业”、“课外作业”来完成。这样课后思考练习题就成了可有可无的赘特。 一、发挥“思考&#183;练习”的目标性的作用 “思考&#183;练习”是一篇课文教学的有机组成部分,它提示了教学的重点、难点或启发学生自学的思路,为教师正确理解教材,学生的自学提供了很好的帮助。教师备课时,要在全面、深入地理解课文的基础上,进一步借助课后“思考&#183;练习”,明确教学的重点、难点,并围绕教学的重点、难点设计教学。教师可以利用“思考&#183;练习”,使学生明确目标后,提出问题让学生带着问题去理解课文内容,在明确目标的前提下去读书。如教学人教版五年制第１０册《马踏飞燕》一课,教师在掌握、理解教材的基础上,借助“思考&#183;练习”,进一步明确本课的教学重点...     

细致观察 展开联想 说写结合——“说话&#183;写话”《扫雪》教学设计

《扫雪》是五年制小学语文第三册教材《基础训练8》的“说话&#183;写话”练习。这个练习要求学生先看单幅图说话,然后把说的内容写下来。这是一次观察、说话、写话能力的综合训练。     

着眼学生需求注重循序渐进——评赵新、李英主编的《阶梯汉语·中级精读》

赵新、李英等主编的《阶梯汉语&#183;中级精读》精选语料内容,适应学生口味,具有实用性、趣味性、通用性和持久性;改写语料文字,控制生词数量,对教材使用者的语言技能进行了明确的量化定位,限制课文长度,使之逐册增加,用中级词和常用词语替换超等级词和超纲词,提高生词重现率;练习目的明确,训练形式丰富,练习覆盖全部教学内容,练习能够满足训练需要。了解学生需求是该教材编得比较好的内在依据。     

《文选》册(策)书源流探颐

对于册(策)书源流,刘勰<文心雕龙*诏策>既有精审的论述,也有疏漏的地方,其精审处,主要得之于他的宗经思想和所掌握的材料;其疏漏的地方,就是忽视了先秦册(策)书的存在.对此本文逐一进行了考证,认为册(策)书是一种出现于商周、且与誓诰并行的重要文书.两汉册(策)书就是在此基础上发展起来的,二者渊源相仍,然又有区别.文章亦分别从使用范围、自身发展规律和体制三个方面进行了阐述和说明.同时对潘勖的<册魏公九锡文>的源流及册(策)书体制建构定型的时间进行了考证.     

符号化思想与小学数学

本文通过回顾和分析符号化思想的发展历史,简要分析国外对这一思想的重要性的认识及其在各国数学教育教材中的渗透,并深入分析<全日制义务教育数学课程标准>(实验稿)及人教版<全日制义务教育小学数学教材>(1册～12册)对这一思想的体现和渗透,并提出在课堂教学中应如何渗透符号化思想的一些问题.     

略谈《文选与习作》(第一册)

《文选与习作》,全书共四册。第一册集中编选了四十五篇优秀记叙文,按状物、写景、记事、写人和综合记叙,分为五个单元,最后有知识短文《记叙文》。为了方便自学,各单元的课文都分为三类。第一类是精读课文,课后附有学习目的,自学辅导资料和练习;第二类是略读课文,课后附有学习重点提示和练习;第三类是独立阅读课文,课后附有思考与练习。第一册还安     

对课后“思考&#183;练习”的分析和运用

笔者曾经对人教版教材课后“思考&#183;练习”的落实情况进行抽样调查,发现：每班随机抽取的10名学生中,二年级上册课后“我会填”部分,78％学生填写了,但有教师批改的仅占20％;高年级“资料袋”“阅读链接”基本作为学生自学材料,课堂上很少被关注,课外也没有相关拓展。可见,课后“思考&#183;练习”不受重视是当今阅读教学的普遍现象。领会、把握课后“思考&#183;练习”的编写意图,用好“思考&#183;练习”,有助于提高阅读教学的实效。

“读“、“背“是第一要求 ——对人教社修订版语文教材“思考&#183;练习“中“读““背“前置的理解

[变化] 　　翻开人教社2002年版六年制小学语文教材,“看点“颇多,除了增加和调整阅读篇目、从形式到内容对“单元练习“进行改版外,还对每篇课文后面的“思考&#183;练习“方阵进行了调整,将“有感情地朗读“或者“背诵“作为第一要求列于“思考&#183;练习“之首,而旧版教材的相关训练全都安排在“思考&#183;练习“的最后.同一训练项目,首尾位置的变换,其内涵及其导向作用小视不得,主要目的在于彻底改变传统的阅读教学方式. 　　……

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.
