(三)赏析课文,品味哲理此环节重在解决本课的重点难点。首先,我运用问答法解决1.2两个问题。问答可以吸引学生注意,激发学生思维,培养学生概括和说话能力。通过学生的回答,即“固一世之雄也,而今安在哉”和“哀吾生之须臾,羡长江之无穷”以及“挟飞仙以遨游,抱明月而长终”这三个句子,最后明确答案:古今历史对比生悲、人生短暂和自然无穷对比生悲、理想与现实矛盾生悲;再以同样的方式分析第4段,通过教师提出问题,学生进行思考和回答这一过程,归纳出“水与月”、“变与不变”和“自然之无尽藏也”这三层哲理,最后得出是苏轼超然洒脱、乐观旷达的人生观劝慰了客人,从而达到第5段中“客喜而笑”的结果。设计两个问题的意图是让学生得以把握苏轼由疑惑沮丧到豁然开朗这一情感变化,从而更好的赏析本文。
3. 教学任务二:PPT子任务一、二、三感悟诗情:那么为什么不能轻易对诗人诗歌进行删减呢?除了诗歌语言及内容方面的影响外,还有重要的一点就是:感情。情感是诗歌的尺度,而非长短。下面将从知人论世的角度再读诗歌。重点赏析曹操的“忧”与“解”和陶渊明的“误”与“归”。通过编写诗人年谱的方式,呈现诗人的各个人生阶段的经历和当时的时代背景,让诗人回到历史现场,让自己代入诗人境遇,以意逆志。通过查阅资料和编写年谱,可以了解到:曹操既能横槊,又能赋诗,如曹丕在《典论·自叙》中所说:“上(曹操)雅好诗文书籍,虽在军旅,手不释卷。”《短歌行》中多用典故和善用比兴或许就源于此。其次,曹操虽出身仕宦,但门第不算高贵,这样的家庭地位让他有着出人头地、建功立业的迫切愿望,因此,“唯才是举”是曹操出于现实的理性选择。再次,曹操写《短歌行》的确切时间已难考证,如取赤壁大战前的说法,曹操已五十四岁,来日无多的紧迫感、贤才归附的愿望自然尤为强烈。
本环节利用多媒体展示的教学手段,通过创设优美的情景来渲染气氛,引导学生接受美的熏陶,增强学生学习兴趣。教师先播放莲花的图片,让学生们谈谈自己联想到的诗词曲赋或文章,来激发学生的学习热情,随后教师总结,引出现代写荷花的名篇《荷塘月色》,从而导入新课。导语部分的设计既给了学生美感享受又自然的导入了新课。(二)初读文本,把握结构本环节主要采用了小组合作法让学生以小组合作的形式探索文章夜游顺序和情感变化这两条线索发展,教师适当的进行点拨,让学生通过探索文章线索完成对本课“圆形结构”把握。目的是发挥学生主导作用,自主学习、把握文章结构美。(三)选读文本,分析手法在本环节中主要运用讲授法和问答法。让学生反复诵读课文第4、5、6段,找出作者使用修辞手法修饰了的景物,随后师生问答作者运用了什么修辞手法来描写“荷塘”“月色”“荷花”“荷香”等景物的,又达到了什么样的效果呢?最后由教师来具体讲解本文中学生不熟悉的写作手法(如:通感)。
活动一:整体感知,梳理要点新修订《课程标准》指出:重视学生的思维发展与提升,如直觉思维、形象思维、抽象思维等。为此,我设计了“梳理要点、绘制思维导图”两个部分,引导学生在阅读中整体感知文本。1、梳理章节要点,明确内容要素《家族》:以西洋家庭特点为对照,分析中国乡土社会家庭的特点。《男女有别》:主要讨论乡土社会感情定向的问题,偏向同性交往,遏制男女交往。2、展示思维导图,凸显整体关联引导同学制作多种思维导图:流程图式、树状图式、爪形图式活动二:走进文本,深化认知新修订《课程标准》指出:学会语文运用的方法,有效地提高语文能力,并在学习语言文字运用的过程中促进方法、习惯及情感、态度与价值观的综合发展。所以在教学中我引导学生掌握整本书阅读的基本方法,即以速读、跳读的方式地毯式地搜索书中关于“中西家庭差别”的内容,得出乡土家族的六个方面的特点,学生分别结合生活中的现象阐述了这六个方面的特点在生活中的具体体现。
此环节运用的是合作探究法,采用小组讨论的形式开放回答即可。通过本课的学习,学生可以总结归纳出辛弃疾主张抗敌,收复失地的爱国热情对南宋政府苟且偏安的不满,吸取的历史教训,告诫当使用者不要草率用兵。对于决策者提出警告,抒发自己壮志难酬的感慨,教师总结归纳即可。本诗写出最大特点就是大量典故的运用。学生可以本诗对用点表达自己的看法,我将在在PPT展示诗歌用典的意义,意在帮助学生理解更好用典这种诗歌技巧。本篇是一首咏史怀古诗,本单元学习了两首同题材诗歌,有必要使学生掌握一类型的诗歌鉴赏方法。(五)比较阅读 品味历史这一环节PPT将展示上次课程学习的《念奴娇赤壁怀古》并从内容,形式等角度分析异同,采用提问的方法。此环节结束后简要归纳咏史怀古诗类型。目的是巩固加强对于咏史怀古题材诗歌理解,理解归纳咏史怀古诗题材类型。(六)布置作业 巩固感知鉴赏李白《越中览古》我将采用习题的形式,目的是使学生在实践中运用所学方法鉴赏咏史怀古诗。
一、说教材选修课是在必修课程基础上的拓展与提高,它力争促进学生各自特长和个性的形成。我们在必修部分已经学习了李白的一首古风《蜀道难》,学生对李白其人及其诗风已有了一定的了解。本单元的任务是“因声求气,吟咏诗韵”,它要求我们通过对古典诗歌声律特点的把握,学习有感情地吟咏,诵读作品,并深入地了解诗歌的感情。《将进酒》一诗时而奔放,时而深沉,感情大起大落变化明显,学生容易进入吟咏和体会情感的体验阅读中。二、说教法学法现代语文观念中提倡语文教学要多读,要培养学生的语感,特别是对一些优秀的古诗文。可见在学习古代诗文的过程中,诵读是非常重要的,有助于加深学生对课文思想内容的理解。可以在朗读中理解诗文的内容,所谓“读书百遍其义自见”,在反复的朗读中可以慢慢体会诗人所要表达的思想感情,因此本堂课我采取以诵读为线索,完成对诗歌思想内容的理性思考。
1. 厘清全文的线索、情节,体会小说结构严谨、清新俊逸的写作风格。2. 分析通讯员、新媳妇的人物形象,通过品味生动的细节来感知人物身上洋溢的人性美、青春美。3.通过自主、合作、探究,从不同角度和层面发掘“百合花”这一主题的独特意蕴。4.通过把握小说人性美、青春美的主题,引导学生提升自身的精神品质和道德情操。教学重点是:通讯员及新媳妇的性格特征分析,小说如何通过细节描写来塑造人物性格。教学难点是:从不同角度和层面发掘“百合花”这一主题的独特意蕴。【教学方法】本文篇幅较长,但我们决定用一个课时来完成教学任务,课前让学生充分预习文本,自己搜集有关“百合花”的知识资料,自主梳理文章的故事情节,自主归纳人物的形象、性格特点。课堂上采用情景激趣法、启发诱导法、合作探究法等教学方法来引导学生学习探究,培养学生的文学鉴赏能力。
第二课时为知人。即利用预习所查到的资料、学生之间的分享以及教师预备的材料,合作探究三个问题:曹操为何如此渴望贤才?天下归心的愿望是否实现?如何评价曹操?本课时采用创设情境的方式,从刘备、曹丕、晚年曹操等多重角度评价曹操,自领角色,利用资料有逻辑地证明自己的观点。教师出示不同学者评价,师生共同研讨评价的技巧和原则,尝试写作短小文学评论。这是解决忧的果。第三课时为回味。创设诵读比赛的情境,在比赛和评价中研讨标点符号的作用,如何读出曹操诗歌独特的特点,以及带着对曹操的认识读出自己的理解。(每组评出最佳朗读者和最佳评论员,上传优秀视频)。这是为了让学生最后读出忧。第五,板书设计。以上是我本节课教学设计的板书,体现了分析本首诗的基本思路和学习方法。
猜谜激趣,导入新课 1.师出谜语:白天不见,晚上出现。又红又圆,照亮地面。 2.出示词卡“太阳”,指导读准字音。 3.出示课题“四个太阳”,指名读,齐读。 4.引导质疑:读了课题,你的小脑瓜里是不是蹦出了小问号? 二、初读课文,认记生字 1.出示课件:带拼音生字,指名带读。 2.出示课件:去拼音生字并打乱顺序,摆字卡,自由练习朗读。 3.游戏:我说你找喊名字。 4.指导识记生字方法。 5.巩固游戏:我把生字送回家。动画演示,指导写字 1.猜谜引入:大口框里有个“大” 2.出示课件:“因”书写笔顺规则 看了动画,你知道了什么? 3.出示课件:“园” “园”与“因”哪里长得很像?书写的时候要注意些什么?(同样先里面后封口) 4.师范写“园”“因”,讲解书写要领。 5.生自由练写,师巡回指导。 6.集体评价。
本节课是在学习了三角函数图象和性质的前提下来学习三角函数模型的简单应用,进一步突出函数来源于生活应用于生活的思想,让学生体验一些具有周期性变化规律的实际问题的数学“建模”思想,从而培养学生的创新精神和实践能力.课程目标1.了解三角函数是描述周期变化现象的重要函数模型,并会用三角函数模型解决一些简单的实际问题.2.实际问题抽象为三角函数模型. 数学学科素养1.逻辑抽象:实际问题抽象为三角函数模型问题;2.数据分析:分析、整理、利用信息,从实际问题中抽取基本的数学关系来建立数学模型; 3.数学运算:实际问题求解; 4.数学建模:体验一些具有周期性变化规律的实际问题的数学建模思想,提高学生的建模、分析问题、数形结合、抽象概括等能力.
四、小结1.知识:如何采用两角和或差的正余弦公式进行合角,借助三角函数的相关性质求值.其中三角函数最值问题是对三角函数的概念、图像和性质,以及诱导公式、同角三角函数基本关系、和(差)角公式的综合应用,也是函数思想的具体体现. 如何科学的把实际问题转化成数学问题,如何选择自变量建立数学关系式;求解三角函数在某一区间的最值问题.2.思想:本节课通过由特殊到一般方式把关系式 化成 的形式,可以很好地培养学生探究、归纳、类比的能力. 通过探究如何选择自变量建立数学关系式,可以很好地培养学生分析问题、解决问题的能力和应用意识,进一步培养学生的建模意识.五、作业1. 课时练 2. 预习下节课内容学生根据课堂学习,自主总结知识要点,及运用的思想方法。注意总结自己在学习中的易错点;
它位于三角函数与数学变换的结合点上,能较好反应三角函数及变换之间的内在联系和相互转换,本节课内容的地位体现在它的基础性上。作用体现在它的工具性上。前面学生已经掌握了两角和与差的正弦、余弦、正切公式以及二倍角公式,并能通过这些公式进行求值、化简、证明,虽然学生已经具备了一定的推理、运算能力,但在数学的应用意识与应用能力方面尚需进一步培养.课程目标1.能用二倍角公式推导出半角公式,体会三角恒等变换的基本思想方法,以及进行简单的应用. 2.了解三角恒等变换的特点、变换技巧,掌握三角恒等变换的基本思想方法. 3.能利用三角恒等变换的技巧进行三角函数式的化简、求值以及证明,进而进行简单的应用. 数学学科素养1.逻辑推理: 三角恒等式的证明; 2.数据分析:三角函数式的化简; 3.数学运算:三角函数式的求值.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
【参考范文】Narrator:(Henry is smiling as he leaves the restaurant. As he is walking down the street, he sees a sign for a place that cuts hair.
