说课稿数学篇一

这篇选自苏教版教材小学语文十二册第四单元,是一篇记叙文,记叙了红三军团长征过草地时,因为断粮了,彭德怀忍痛命令把自己最喜爱的大黑骡子和其他牲口全部枪杀的事,表现了彭德怀爱大黑骡子更爱战士们的感情,赞扬了他与战士同甘共苦的精神。全文共21自然段,可分为三段。

第一段(1)江红军过草地时饥寒交迫,后续部队连野菜也挖不到了。

第二段(2-20)彭德怀忍痛命令把连同大黑骡子在内的六匹牲口枪杀的经过。

第三段(21)讲大黑骡子融进了北进的滚滚铁流中。

根据《课程标准》对高年级识字、阅读的要求,又根据以上教材的分析。

我认为本课的认知目标是:①学会本课生字新词②体会“艰苦、燃眉之急”等词语在文中的意思及用法。

技能目标为:①能正确、流利有感情的朗读课文。②体会“它融进了北进的滚滚铁流中”这句话的含义。

情感、态度价值观目标为:学生在品味朗读课文的基础上,体验彭德怀与战士同甘共苦的精神,并阅读有关于彭德怀及其他伟人的,学习他们的精神。

教学重点:让学生在反复朗读、讨论、评价的过程中,让学生通过人物的语言、动作、神态等具体的描写,去体会彭德怀爱大黑骡子,更爱战士们的思想感情。

教学难点:理解“它融进了北进的滚滚铁流中”这句话的意思。课时建议:由于本课凭借多媒体辅助教学,再读中感悟,激发学生学习自主性,用2教时就能完成任务。

本课根据学生身心发展特点和教材特点,采用下列方法:

①创设情境法激发学生学习兴趣。

②自主探究法让学生自读自悟,自主获取知识,发现问题,体悟感情,从而真正成为学习的主人。③朗读感悟法朗读是学生学习的重要手段,他能帮助学生理解课文内容、领悟课文情感、积累语言词汇、陶冶情操。本课通过多种形式的朗读,让学生感悟体验,表达自己所体验的情感,同时对学生朗读进行适时评价,激发学生向更高的朗读目标努力。

第一教时教会学生学习本科生词,反复熟读课文,理解词语意思,会用“燃眉之急、艰苦”说话。

第二教时:细读课文,品味朗读,增加体验,拓展延伸。

具体环节:

第一教时(分四个环节:)

(一)、运用多媒体引出课题多媒体出事大黑骡子,画面转换出示彭德怀英雄形象的图片,让学生认识大黑骡子,明白彭德怀的丰功伟绩。

(二)、初读课文整体感知要求学生读准生字词。读通课文,了解课文主要讲了一件什么事?

(三)、再读课文,理解内容请同学们轻声读课文,看读懂了哪些内容?有疑问的地方适当作上记号,读完讨论、交流、质疑。老师适当点拨。(这一环节分三步:一是让学生自学课文,二是让学生在小组里讨论、交流,三是在班级里交流的同时遇有疑问能解决的当堂解决,不能解决的让学生在下节课再读课文解决。)整个过程体现学生主体性,教师只在课文的重点除给予必要知道,并给学生的学习以积极的评价和激励,为下一堂课打下坚实的基础。

第二教时

一、教师范读、学生体会评价

1、教师范读课文2-20小节,学生听、体会,然后说一说、议一议、评一评,好的表扬,不足的指出。2、学生评:重点评议老师是否把彭德怀十分爱大黑骡子的感情读出来,是否感受到彭德怀不忍杀大黑骡子的痛苦心情。3、根据学生的评议,老师把大家所说的概括成这样两条要求:⑴读出彭德怀既爱又不忍心杀大黑骡子使得痛苦的心情。⑵读出战士不忍杀大黑骡子的感情。

二、学生反复练读,体验、评改

1、学生模仿老师练读可以分小组、可以分角色读,教师住个小组进行视察,不足的帮助学生纠正。

2、指明分角色读(课文比较长,分2-7小节、8-20小节两个小组读,其中每个小组四人个分别读彭德怀、老饲养员、战士、旁白的话)其他同学仔细听、体会,然后评议他们那些地方读的好,为什么?不够的我们来帮助他。3、大家分角色有感情齐读课文。(这一环节设计主要是让学生通过多种形式的读,使全体学生积极参与,相互评价,交流。学生对课文理解得到升华,领悟把握了语感,从而从整体上对科文从语言文字到思想内容及形象等形成了内化和积累。)三、学习第三段。理解“它融进了北进的滚滚铁流中”这句话的含义。四、总结延伸激发学生看有关于红军长征途中伟人的故事。(这一环节设计主要是依据课程标准培养学生广泛的阅读兴趣,鼓励学生自主选择阅读材料而设计的)

说课稿数学篇二

《锐角三角函数》(第一课时),所选用的教材为人教版义务教育课程标准实验教科书。根据新课标的理念,对于本节课,以教什么,怎样教,为什么这样教为思路,从教材分析,教学目标分析,教学方法和学法分析,教学过程分析四个方面加以说明。

1、教材分析

本节教材是人教版初中数学新教材九年级下第28章第一节内容,是初中数学的重要内容之一。一方面,这是在学习了直角三角形两锐角关系、勾股定理等知识的基础上,对直角三角形边角关系的进一步深入和拓展;另一方面,又为解直角三角形等知识奠定了基础,也是高中进一步研究三角函数、反三角函数的工具性内容。鉴于这种认识,我认为,本节课不仅有着广泛的实际应用,而且起着承前启后的作用。

2、学情分析

从学生的年龄特征和认知特征来看:

九年级学生的思维活跃,接受能力较强,具备了一定的数学探究活动经历和应用数学的意识。

从学生已具备的知识和技能来看:

九年级学生已经掌握直角三角形中各边和各角的关系,能灵活运用相似图形的性质及判定方法解决问题,有较强的推理证明能力,这为顺利完成本节课的教学任务打下了基础。

从心理特征来看:九年级学生逻辑思维从经验型逐步向理论型发展,观察能力,记忆能力和想象能力也随着迅速发展。

从学生有待于提高的知识和技能来看:

学生要得出直角三角形中边与角之间的关系,需要观察、思考、交流,进一步体会数学知识之间的联系,感受数形结合的思想,体会锐角三角函数的意义,提高应用数学和合作交流的能力。学生可能会产生一定的困难,所以教学中应予以简单明了,深入浅出的剖析。

3、教学重点、难点

根据以上对教材的地位和作用,以及学情分析,结合新课标对本节课的要求,我认为本节课的重点为:理解正弦函数意义,并会求锐角的正弦值。

难点为:根据锐角的正弦值及一边,求直角三角形的其它边长。

新课标指出,教学目标应从知识技能、数学思考、问题解决、情感态度等四个方面阐述,而这四维目标又应是紧密联系的一个完整的整体,学生学知识技能的过程同时成为学会学习,形成正确价值观的过程,这告诉我们,在教学中应以知识技能为主线,渗透情感态度,并把前面两者通过数学思考充分体现在问题解决中。借此结合以上教材分析,将四个目标进行整合,确定本节课的教学目标为:

1. 理解锐角正弦的意义,并会求锐角的正弦值;

2 掌握根据锐角的正弦值及直角三角形的一边,求直角三角形的其它边长的方法;

3 经历锐角正弦的意义探索的过程,培养学生 观察分析、类比归纳的探究问题的能力;

4 通过主动探究,合作交流,感受探索的乐趣和成功的体验,体会数学的合理性和严谨性,使学生养成积极思考,独立思考的好习惯,并且同时培养学生的团队合作精神。

现代教学理论认为,在教学过程中,学生是学习的主体,教师是学习的组织者、引导者,教学的一切活动都必须以强调学生的主动性、积极性为出发点。根据这一教学理念,结合本节课的内容特点和学生的学情情况,本节课我采用“三动五自主”的教学模式,以问题的提出、问题的解决为主线,始终在学生知识的“最近发展区”设置问题,倡导学生主动参与教学实践活动,以独立思考和合作交流的形式,在教师的指道下发现、分析和解决问题,在引导分析时,给学生流出足够的思考时间和空间,让学生去联想、探索,从真正意义上完成对知识的自我建构。

本节课的教法采用的是情境引导和自学教学法,在教学过程中,通过适宜的问题情境引发新的认知冲突;建立知识间的联系。教师通过引导、指导、反馈、评价,不断激发学生对问题的好奇心,使其在积极的自主活动中主动参与概念的建构过程,并运用数学知识解决实际问题,享受数学学习带来的乐趣。

本节课的学习方法采用自主探究法与合作交流法相结合。本节课数学活动贯穿始终,既有学生自主探究的,也有小组合作交流的,旨在让学生从自主探究中发展,从合作交流中提高。

新课标指出,数学教学过程是教师引导学生进行学习活动的过程,是教师和学生间互动的过程,是师生共同发展的过程。为有序、有效地进行教学,本节课主要安排以下教学环节:

(一)自学提纲

1、 已知:在rt△abc中,∠c=900,∠a=30°,bc=10m,求ab

已知:在rt△abc中,∠c=900,∠a=30°,ab=20m,求bc

设计意图:建构注意主张教学应从学生已有的知识体系出发,相似的三角形性质是本节课深入研究锐角正弦的认知基础,这样设计有利于引导学生顺利地进入学习情境。

2、 创设情境,提出问题

利用多媒体播放意大利比萨斜塔图片,然后老师问:比萨斜塔中条件和要探究的问题:“你能根据问题背景画出直角三角形并且利用边求出斜塔的倾斜角吗?”这就是今天我们要学习锐角三角函数(板书课题)

设计意图:以问题串的形式创设情境,引起学生的认知冲突,使学生对旧知识产生设疑,从而激发学生的学习兴趣和求知欲望。

通过情境创设,学生已激发了强烈的求知欲望,产生了强劲的学习动力,此时我把学生带入下一环节。

(二)合作交流

1、阅读课本p74问题与思考 (要求学生独立思考后小组内合作探究)

结论:直角三角形中,30°角的对边与斜边的比值 。

2、阅读课本p75思考,并求值

结论:直角三角形中,45°角的对边与斜边的比值 。

设计意图:现代数学教学论指出,数学知识的教学必须在学生自主探索,经验归纳的基础上获得,教学中必须展现思维的过程性,在这里,通过观察分析、独立思考、小组交流 等活动,引导学生归纳。

3、阅读课本p75探究 。

问:锐角a度数一定时,不管直角三角形的大小如何,它的对边与斜边的比有什么关系?你能解释吗?

4、正弦函数定义:在rt△abc中,∠c=900,把锐角a的对边与斜边的比叫做∠a的正弦,记作sina,即sina=bc/ab

对定义的几点说明:

1、sina是一个完整的符号,表示∠a的正弦习惯上省略“∠”的符号.

2、本章我们只研究锐角的正弦。

通过前面的学习,学生已基本把握了本节课所要学习的内容,此时,他们急于寻找一块用武之地,以展示自我,体验成功,于是我把学生引入到下一环节。

(三)自主展示(强化训练,巩固双基)

1、(例1课本p76)已知:在rt△abc中,∠c=90°,根据图中数据

求sina和sinb

2、课本77页练习

3、判断对错(学生口答)

(1)若锐角∠a=∠b,则sina=sinb ( )

(2)sin60°=30°+sin30° ( )

4、将rt△abc各边扩大100倍,则sina的值( )

a.扩大100倍 b.缩小100倍 c.不变 d.不确定

5、平面直角坐标系中点p(3,- 4),op与x轴的夹角为∠1,求sin∠1的值。

6、在rt△abc中,∠c=90°,bc=6,sina=3/5,求:ab, ac的长。

设计意图:例题及练习题由浅入深、由易到难、各有侧重,体现新课标提出的让不同的学生在数学上得到不同发展的`教学理念。这一环节总的设计意图是反馈教学,内化知识。

(四)自主评价(小结归纳,拓展深化)

我的理解是,小结归纳不应该仅仅是知识的简单罗列,而应该是优化认知结构,完善知识体系的一种有效手段,为充分发挥学生的主题作用,从学习的知识、方法、体验是那个方面进行归纳,我设计了这么三个问题:

① 通过本节课的学习,你学会了哪些知识;

② 通过本节课的学习,你最大的体验是什么;

③ 通过本节课的学习,你掌握了哪些学习数学的方法?

(五)自主拓展(提高升华)

1、课本习题28.1第1、2、题。(只做与正弦函数有关的部分);

2、选做题:已知:在rt△abc中,∠c=900,sina=1/3,周长为60,求:斜边ab的长.

以作业的巩固性和发展性为出发点,我设计了必做题和选做题,必做题是对本节课内容的一个反馈,选做题是对本节课知识的一个延伸。总的设计意图是反馈教学,巩固提高。

以上几个环节环环相扣,层层深入,并充分体现教师与学生的交流互动,在教师的整体调控下,学生通过动脑思考、层层递进,对知识的理解逐步深入,为了使课堂效益达到最佳状态,我设计以下问题加以追问:

1、sina能为负吗?

2、比较sin45°和sin30°的大小。

设计要求:(1)先学生独立思考后小组内探究

(2)各组交流展示探究结果,并且组内或各组之间自主评价.

设计意图:

(1)有一定难度需要学生进行合作探究,有利于培养学生善于反思的好习惯.

(2)学生通过互评自评,可以使学生全面了解自己的学习过程,感受自己的成长和进步,同时促进学生对学习及时进行反思,为教师全面了解学生的学习状况,改进教学,实施因材施教提供重要依据。

教学反思

1.本教学设计以直角三角形为主线,力求体现生活化课堂的理念,让学生在经历“问题情境——形成概念——应用拓展——反思提高”的基本过程中,体验知识间的内在联系,让学生感受探究的乐趣,使学生在学中思,在思中学。

2.在教学过程中,重视过程,深化理解,通过学生的主动探究来体现他们的主体地位,教师是通过对学生参与学习的启发、调整、激励来体现自己的引导作用,对学生的主体意识和合作交流的能力起着积极作用。

3.正弦是生活中应用较广泛的三角函数。因而在本节课的设计中力求贴近生活。又从意大利比萨斜塔提炼出了数学问题,让学生体会学数学、用数学的乐趣。

说课稿数学篇三

各位评委晚上好:

我是xx班的xx。

今天我说课的题目是《物质的分散系》。本节内容选自苏教版化学1专题一第一单元。教材以日常生活中的实例为切入点,引入了分散系的概念。在回顾初中知识浊液、溶液的基础上,重点介绍了胶体的性质与应用。并由溶液的导电性过渡到电解质、非电解质的知识,以此引入了电离方程式的书写。

本节内容被安排在《化学1》的第一个专题,是对学生初中科学中已经接触过的溶液和浊液这两种混合物的相关知识的一个延续和拓展。同时,也将为后续的强、弱电解质以及离子方程式的书写等知识的学习奠定知识基础。因此,本课程在教材体系中具有承上启下的作用。但是初中科学并没有从分散系的角度对混合物进行分类,并且胶体的相关知识对学生而言更是一个较为陌生的领域。

基于以上分析并结合《学科指导意见》的要求,我将本节课的教学重点定为,分散系的区分以及掌握胶体的性质与应用。

本课时的教学对象为高一年级的学生,他们虽然思维活跃但不够严谨,缺乏正确的科学探究方法,同时他们比较喜欢动手做实验并且已经具备了一定的操作能力,但是对于丁达尔效应可能还停留在观察阶段,缺乏深层次的分析,对于胶体性质的理解仍具有一定困难。因此,我将本节课的教学难点定为,从结构特点上理解胶体的性质。

针对以上内容我制定了如下的教学目标:

1.说出分散系的含义和常见类型,能用物质的分散系解释一些实际的问题。

2.掌握胶体的性质和应用。

3.区别电解质和非电解质,初步学会书写电离方程式。

1.通过观察、实验、交流,掌握多种获取信息的手段,并运用比较、分类、归纳等方法对信息进行加工。

2.通过问题情境的讨论,形成自主探究、合作的科学学习方式。

通过了解胶体在日常生活中的应用,增强将化学知识应用于生产生活实践的意识,感受化学对个人生活和社会发展的贡献。

根据《高中化学课程标准》对探究和合作学习的要求,本节课我主要采用实验探究、

交流讨论、归纳分析等方法,并结合讲授法、自主学习法、多媒体辅助教学法,以此来实现我的教学目标。

首先,我会用幻灯片播放三张图片,雨过天晴的后的云层缝隙中透射的光线、高山上的云雾、美味可口的果冻布丁。激发学生的学习兴趣,同时引入本节课的知识----胶体。

我将以学生在初中学习过的溶液和浊液的知识为引导,通过比较分析得到分散系的概念。首先我将让学生举例生活中常见的溶液和浊液的例子,并提问“那么溶液和浊液之间有什么共同点呢?”,引发学生们的思考。我将组织学生交流讨论,得出浊液和溶液的共同点,以此引入分散系的概念,并依据分散质粒子直径的大小对其分类,浊液的分散质粒子的直径大于100纳米,溶液的分散质粒子的直径小于1纳米。同时提问介于两者之间的是什么,引入胶体的概念。并将胶体与浊液和溶液做相应的比较。

通过对照实验探究胶体的性质,以此达到教学难点的突破。

探究一 丁达尔现象,即:溶液与胶体的性质探究

我将在课堂上演示实验:在暗处,用激光笔分别照射硫酸铜溶液和氢氧化铁胶体,从垂直于光线的方向观察实验现象。发现光束通过氢氧化铁胶体时,在垂直与光线的方向可以看到一条光亮的通路,而溶液没有。以此我将采用边讲边实验的方法引导学生比较溶液和胶体的区别,掌握胶体区别于溶液的本质特征和鉴别方法。

探究二 净水作用,即:浊液与胶体的性质探究

我将进行另一个演示实验:在两只烧杯中加入等量的含有悬浮颗粒物的浑浊污水,向其中一只烧杯中加入适量的氢氧化铁胶体,搅拌后静置片刻,比较至少被中液体的浑浊程度。同样的,采用边讲边实验的方法引导学生观察胶体的净水作用,得出氢氧化铁胶体能够使水中悬浮的固体颗粒凝聚沉降。并组织学生自主阅读,了解胶体的其它应用。

至此,学生对胶体有了一定的了解,我将组织学生交流讨论,总结归纳胶体的性质,并对胶体聚沉后遇到过量的电解质会溶解做简单补充。

之后,我将通过创设情境,引导学生用物质的分散系解释一些实际生产生活中的问题。

我将采用基于建构主义理论的抛锚式教学模式,在课堂上演示溶液的导电性实验,根据实验现象提出疑问:“为什么氯化钠、氢氧化钠、盐酸可以使小灯泡发光而酒精、蔗糖溶液不可以呢?”引导学生回顾电解质、非电解质的概念,掌握两者的异同。在此基础上,我将再次发问:“电解质能够导电的本质原因是什么?”以此引入电离的概念,并对电离方程式的书写做初步介绍。

最后,我将对本堂课进行小结,并布置形成性练习。

(五)作业设计

(六)板书设计

语文作为重要的文化载体,承载着人类文化方方面面的思想,它不能脱离所表达的内容孤立存在,其中就兼顾生命教育的的传统,古典时期的语文甚至是为即在生命意识形态而存在的。新时代的语文教学,已经确立的昌明的人文精神,新课标更是把语文的性质定位工具性和人文性的统一,在这种前提下,提升“人”的生存意义是很有必要的。现在正在试行的人教社试验修订高中语文教材在战略上作了重大调整,一批闪耀人性光辉的好文章以崭新的面目出现。第二册的《我与地坛》以及今天我要说的《假如给我三天光明》都是这样的好作品。

(一)单元教学理念

本单元是第三册的第一个抒情散文单元。鉴赏抒情散文要深入领会作者的思想情感。阅读教学的原则是“批文入情”,由“感”入“悟”,“感”是基础,“悟”是升华和沉淀的结果。教学过程中,让学生各有所“感”、所“悟”,才是创新,才是真正的鉴赏。

(二)单元教学思路

散文的赏析因文而异。《我的空中楼阁》从不同的角度精心描绘作者自己心爱的小屋,与《故都的秋》的随意点染几处特色景物的写法不一样;同样是心理景象《灯》以联想为主,《假如给我三天光明》以想象为主,高昂着生命的激情。教学过程中,应该抓住其中最有特色的一两个方面,重点突破,不必面面俱到。

在导语中我已经说过,这是一篇闪耀着人性光辉的好作品,我将本文看作高中语文教学与对学生进行生命教育相整合的典范性文本。学习本文能使学生了解海伦·凯勒的精神源泉,那就是她对生命的珍视,对生存的渴望,对生活的赞美,对人类的友善情感和战胜困难的坚定信念。

(一)教学内容:教师通过引导,在教师、教材、学生之间形成情感的共鸣;学生通过阅读、比较、联想,走入作者的内心世界。

(二)教学方式:多媒体辅助教学。

(使用依据:新课标要求我们,要充分利用现代教育资源,电化教学具有声、光、形、色同时展现的特点,对于激发学生的情趣,增强课堂的感染力,具有重要的作用。)

(三)教学方法:引导、鉴赏、评说、比较、联想相结合。

(使用依据:语文教学应该激发学生学习兴趣,为学生创立良好的自主学习情境。教师应该创造性地理解和使用教材,引导学生在实践中学会学习。)

(四)教学课时:一课时

(一)教学目标:

1、生命教育目标:学习作者的精神,丰富自己对生活的认识。

2、能力培养目标:训练学生的联想和想象能力。

3、知识培养目标:训练学生整体阅读、信息帅选、对比阅读能力。

(确立依据:本单元其他三篇作品的教学以鉴赏为重点,因此本篇课文目标设计我想另辟蹊径,在知识能力培养的基础上,注重对学生的人文关怀。)

(二)教学重点:如何通过课堂以及作品,让学生走入教师、海伦·凯勒、史铁生三个残疾人的内心世界。

(三)教学难点:培养学生的联想和想象的能力。

(确立依据:我认为,本文的教学重点是我在教学过程中的一个比较大胆的创新。文本、教师、学生怎样达到情感的共鸣,是语文教学过程中的一个重要问题。教学难点安排在对学生联想和想象上,因为《假如给我三天光明》全文都是以“假设”为基础,教学过程也将需要在阅读的基础上,充分让学生展开想象的翅膀。)

(四)教学过程

(1)了解作者海伦·凯勒的相关资料。

(2)阅读课文,明确作者在假设的三天中,做了些什么。

(3)重新回顾、阅读高中第二册史铁生的《坛我与地》,体会两个人对人生命运的不同体念。

(确立依据:知人论世是阅读文学作品的前提,所以了解作者有必要。本文课堂教学的重点必须在课外阅读的基础上才能得到实现。)

在20世纪,有一个盲人,以她独特的生命及其勇敢的方式,震撼了世界,她就是海伦·凯勒。一生中,她度过了88个春秋,却熬过了87个无光、无声的岁月。但是,就是这样一个人,却获得了至高无上的荣誉,美国公民最高荣誉——总统自由勋章,1965年她还被评为世界十大杰出妇女之一。马克·土温说,19世纪出现了两个了不起的人物,一个是拿破仑,一个是海伦·凯勒。

(设计思路:学生面对多媒体画面,二胡名曲《二泉映月》悠扬的旋律响起。教师用饱含情感的语言介绍作者,使学生受到感染。)

(1)教师:一个失去光明的人的世界,我也许难以想象的,但是,我却理解另外一种痛苦——身体残疾,失去行动的自由。在走进《假如给我三天光明》之前,也许同学们会想,假如给我三天健康,我会去做些什么呢?

(2)多媒体演示第一模块教学过程。

(设计思路:作为一个残疾教师,我的人生体验,或许能够给学生更真实、亲切、可信的感受。阅读教学的过程应该是教师与文本、学生与文本、教师与学生、学生与学生进行多边交流的过程。课堂要以教材蕴含的情感为源头,以教师的情感外观为渠道,流向学生心里,从而引起学生的共鸣,促进学生的思维,引发学生的思考,形成一定的情感氛围。也就是在这个氛围中,教师与学生,学生与学生通过对文本的阐释,达到阅读教学的目标。)

(1)教师:同大家一起分享了对我来说无比愉悦的三天恢复健康的快乐时光,下面让我们陪同海伦·凯勒进入她想象中的光明世界。

(2)多媒体演示第二模块教学过程。

(设计思路:本模块重点解决两个问题,一是理清楚作者想象中三天的活动内容,二是这些想象如何真实得表现作者的内心世界。第一个问题重点考察学生对信息的筛选和对文章的整体把握,这是高一年级语文学习的重要目标;第二个问题考查学生的鉴赏能力,也是本单元教学重点,是对前面三篇课文学习情况的一个检阅。)

(1)教师:我们在高中第二册课本里,还学习了另外一篇残疾作者的作品,就是史铁生的《我与地坛》,我已经布置了大家将这篇文章与《假如给我三天光明》对照阅读。接下来希望大家说说看,假如给史铁生三天健康,他将会如何度过?

(2)多媒体演示第三模块教学过程。

(设计思路:也许有人说,你已经说了“假如给我三天健康”这个模块,这第三模块的设计是否多余?我的想法是,这两篇文章不仅作者的遭遇相同,更重要的是,它们分别从两个不同的方面,揭示了如何正确面对生命中出现的不幸这样一个现实问题。《我与地坛》记述了作者面对厄运的心灵觉醒和奋进过程;《假如给我三天光明》让我们明白了如何在不幸中用真情拥抱生活。两者对比阅读、思考,无疑会给学生更多的启迪。)

(1)我们都希望人生的道路上一番风顺,可是,有的时候,在灾难的来临却是突如其来的。假如,我们仅仅是假如,假如让你失去三天光明,你们将如何面对呢?

(2)多媒体演示第四模块教学过程。

(设计思路:这一模块和上一模块的都是检阅学生的想象和联想的能力,但是作用却不一样,前者在上面已经说了,而在这一环节中,我想让学生设身处地想一想,如何面对苦难这样一个严肃的话题,既能更好地理解作者的思想情感,也能引导学生关爱生命,珍惜健康,完成生命教育的目标。)

教师:同学们,我们从海伦·凯勒的三天光明中,从史铁生面对地坛的思考中,没有看到恐惧、凄凉、悲哀,看到的是光明的内心,坚强的意志,对生活无比的热爱,他们的人生之路更应该是一曲高昂的《命运交响曲》。

(设计思路:师生在贝多芬《命运交响曲》中,结束教学。)

将《假如让我失去三天光明》写成一篇600字左右的作文。

假如给我三天健康现实中的我和你珍惜拥有

假如给我三天光明

联想想象

假如给史铁生三天健康

假如让你失去三天光明作品中的她和他热爱生命
