“深入探究，把握主旨”这一步则是解决教学的重点难点，这里涉及到课文的深层意蕴，学生理解有难度，教师在通过问题引领学生探讨的基础上，还要适时启发、点拨，因为教学时间有限，让学生漫无边际的讨论，可能难以完成预定的教学任务，会使教学过程不完整。至于本文的写作特点的教学视时间而定，有时间可以让学生说一说，没有时间用小黑板出示一下，让学生了解就行，如果时间不够，甚至可以不讲。第三阶段是“延伸练习，巩固提高”。
人教版高中语文必修2《我有一个梦想》说课稿2篇
(2).教学手段为了使我根据教材而设计的三个教学目标以及重点难点得以的突出和突破,达到最大化的展示境界,同时也为了配合以上我选择的四种教法得以完满实现,我决定采用“多媒体”教学手段进行全程教学。利用电脑的信息容量大,操作简便等优点,形象生动的直观展示教学内容,不但提高学习效率和质量,而且容易激发学生的学习兴趣和调动学习的积极性。四、说学法我为学生设计了三个学习方法：1.让学生学会在探究中学。通过“对黑人严酷处境的探究”和对文中重点语句的探究,培养学生在探究中学习的能力。2.让学生学会在读中学。通过“诵读法”指导学生在诵读过程中感受演讲词内在的魅力,学会在读中学。3.让学生学会在练习中学。通过“课外延伸练习法”,对所学的知识进行运用,培养学生的创新和自学能力。
人教版高中语文必修1《包身工》说课稿2篇
（一）解题：包身工──旧社会一种变相的贩卖奴隶的形式。被贩卖的多是女孩子由承办人送到工厂做工，无人身自由，所得工资全部归承办人所有，在这种形式下做工的人也称包身工。包身工是指二三十年代（时间），在上海东洋纱厂里（地点），为外国人工作的女工（工作性质）。因为这些女工在进厂时已经签订了卖身契，失去了人身的自由权，所以被称为“包身工”。标题中的“包身”二字，突出了帝国主义、封建势力对中国女童工的残酷剥削的罪行，控诉了他们的野蛮残暴的统治手段，以激起人们的义愤和同情，这是全文的中心思想。（二）关于报告文学：《包身工》属于报告文学。(同类题材有初中的《地质之光》、《谁是最可爱的人》)报告文学，是文学体裁的一种，散文的一类，是文艺通讯、速写、特写的总称，是文学创作中的“轻骑兵”。
人教版高中语文必修2《涉江采芙蓉》说课稿2篇
一、说教材1．教材分析《涉江采芙蓉》是新人教版必修二第二单元《古诗三首》中的一首。《古诗十九首》在中国古代诗歌的艺术手法上起着承前启后的作用，在高中语文古诗教学中也起着承前启后的作用。这首古体诗不论是艺术上，还是在思想上都已经达到了十分纯熟的境界。因此，它十分重要。2.说学情这首诗歌在内容上难度不大，可以做多角度解读。新课程标准鼓励学生作个性化解读，我们可以引导学生就此作些探讨。学生通过小学、初中的系统学习和本册古诗部分的集中学习，有了一定的古诗鉴赏能力，对源远流长的中华文化也有了一些积淀，兴趣渐浓，这是进一步引导学生热爱古代诗歌、学习古代诗歌的一个前提。3.教学目标依据学生特点，教材特色以及新课标的要求，制定教学目标如下：（用多媒体展示）1、了解关于《古诗十九首》的文学常识;2、感受诗歌的思想内涵;3、运用想象描摹诗歌的艺术画面。
人教版高中语文必修2《兰亭集序》说课稿3篇
（二）分析课文，理清思路第1、2段为第一部分，主要是叙事、写景，先叙述集会的时间、地点，然后渲染出兰亭优美的自然环境。在这里足以“游目骋怀”“极视听之娱”，可以自由地观察、思考，满足人们目视耳闻的需求。这里正是与会“畅叙幽情”、尽兴尽欢的绝好处所。这些描写都富有诗情画意，作者的情感是轻松愉快的。第3、4段为第二部分，主要是抒情、议论，作者由美景妙时引发出乐与忧、生与死的感慨。他认为人生的快乐是有极限的，待快乐得到满足时，就会感觉兴味索然。往事转眼间便成为历史，人到了生命的尽头就会死亡。作者由“一死生为虚诞，齐彭殇为妄作”的认识，产生了一种珍惜时间、眷恋生活、热爱文明的思考。虽然文中的寿夭、生死不能自由决定，从而有些伤感，但作者仍然认识到盛衰、生死是必然的。人生无常，时不我待，故著文留传后世，以承袭前人，启示来者。
人教版高中语文必修1《优美的汉字》说课稿
明确：（1）结绳记事说。原始记事的一种方法。人类在没有发明文字或文字使用尚不普遍时，常用在绳索或类似物件上打结的方法记录数字，表达某种意思，用以传达信息，处理事件。 （2）书画说。（3）仓颉造字说。中国自古就有仓颉造字之说。文字的发明是人类发展史上一件石破天惊的大事，它将人们的思维、语言、经验以及复杂的社会现象记录下来，使文化得以传播交流、世代传承。2、汉字的形体：中华民族五千年的历史中，汉字的演变，从甲骨文－－金文－－大篆－－小篆－－隶书－－草书－－楷书－－行书，字形由象形到点横竖撇捺的方块字，经历了漫长的岁月。其中凝聚着民族的智慧，也体现出汉字逐步完善的过程，凸显其方方正正、四平八稳的特点。汉字又是一种文化的体现，那些经过艺术处理的汉字或跳起了拉丁舞、有的如同酒醉的成龙打起了醉拳，更是让我们感到的是在欣赏汉字在纸张上跳舞，所以：书法是“纸上的舞蹈”。请大家看到书上的相关内容，注意每一种形体的汉字的载体是什么，其功能又有什么不一样。
人教版高中语文必修1《雨巷》说课稿3篇
一.教材理解教材地位与作用：本单元“阅读与鉴赏”部分，本单元要求学生能在了解诗歌创作的时代背景的情况下通过反复诵读诗歌，把握其中丰富的意象，领悟诗歌独特的意境和诗人所要表达的情感。《雨巷》是现代派大师戴望舒的成名作和前期的代表作,他曾因此而赢得了“雨巷诗人”的雅号。本单元以《雨巷》为例子给学生展示了象征主义诗歌的特点，《雨巷》运用了象征性的抒情手法。诗中那狭窄阴沉的雨巷，在雨巷中徘徊的独行者，以及那个像丁香一样结着愁怨的姑娘，都是象征性的意象。这些意象又共同构成了一种象征性的意境，含蓄地暗示出作者即迷惘感伤又有期待的情怀，并给人一种朦胧而又幽深的美感。富于音乐性是《雨巷》的另一个突出的艺术特色。诗中运用了复沓、叠句、重唱等手法，造成了回环往复的旋律和宛转悦耳的乐感。因此我把本课的教学重点和难点确定为：教学重点：通过反复诵读，领略诗歌的音乐美以及分析其成因教学难点：分析意象以及其象征意义初步掌握鉴赏诗歌的方法
人教版高中语文必修1《小狗包弟》说课稿
探究、讨论、交流：1、包弟讨人喜欢，作者却不得不将它送走，为什么？2、送走包弟后，作者为什么先是感觉轻松，随后觉得沉重？3、“您的小狗怎样？”这句话反复出现，有什么用意？4、“整整十三年零五个月过去了”“整整”一词有什么作用？5、“满园的创伤使我的心仿佛又给放在油锅里熬煎”这句话如何理解？6、“我怀念包弟，我想向它表示歉意。”如何理解？学生各抒己见后教师结合材料发表看法明确总结特别是最后一个问题得出作者这发之心底的语言，不仅仅是歉意，更是发自灵魂深处的忏悔！是对生命的尊重，是一个有良知的作家对反省历史的呼号。第三环节“认识你自己”——忏悔意识与我引导学生正视和反省成长过程中曾犯下过错。并布置课后作业：要求学生课后在本周随笔中谈反省忏悔后的感受。
人教版高中语文必修2《短歌行》说课稿2篇
一、说教材《短歌行》是普通高中课程标准实验教科书必修（二）第二单元的一篇略读课文，本单元安排的是先秦到南北朝时期的诗歌。《短歌行》是著名政治家、军事家、文学家曹操的作品。诗中抓住“忧”字来写诗人为什么“忧”，如何解“忧”，从而表达希望能够招揽人才、完成统一天下的雄心壮志。所以本单元安排《短歌行》一诗，对学生全面了解曹操，感受曹操在短暂的人生中竭力创造伟业的气概。二、说学生我这一课的教学对象是高一学生。他们进入高中学习的时间只有三个多月，现在已经完成了必修（一）的学习。学习了现代诗歌单元，有了一定的诗歌学习基础，初步掌握了读诗的基本方法，但是还未能形成成熟的稳定的学习方式。同时，本单元学习是高中第一次接触古代诗歌，诗歌语言上的障碍和时间上的跨度对他们来说都是学习上的困难。因此教师要引导学生自主学习，合作学习，为他们设置新的学习情境，提供合作探究的机会。
人教版高中语文必修3《马嵬（其二）》说课稿
生2：颔联的意思是只听到禁卫军中传来夜间巡逻的梆子声，不再向宫中那样安逸地听到有鸡人打鸣报时的声音了。生3：颈联的意思是说事变发生那天军队发生哗变停留不前，但当年唐玄宗以为自己可以和贵妃天天在一起，对天上的牵牛和织女一年一度的会见还加以嘲笑呢。生4：尾联的含义是为什么唐玄宗当了四十五年的皇帝，还不如普通百姓夫妻恩爱，长相厮守。师：好的。请大家再齐读一遍诗文，做到人人都能疏通诗的含义。学生再次齐读。第三环节：专项探究师：白居易曾说：“文章合为时而著，歌诗合为事而作。”这首诗就是作者途经马嵬驿，咏马嵬之变这一历史事件而作，所以我们鉴赏的第三步，就是通过标题和诗文，弄清诗中的历史事件。请同学们找出诗中哪些诗句描述了这一事件？
