部编版语文七年级上册《穿井得一人》说课稿
一、说教材《穿井得一人》是初中语文部编教材七年级上册第六单元的讲读课文《寓言四则》中的一则.第六单元是一个以想象为主题的单元，包含了童话、诗歌、神话和寓言，引人遐想，能引导我们换一种眼光看世界。新课标要求学生能主动进行探究学习，激发想象力和创造潜能，在实践中学习和运用语文。第六单元正是为了体现这一要求。语文课标还要求:应使学生初步学会运用祖国语言文字进行交流沟通，吸收古今中外优秀文化，提高思想文化修养，促进自身精神成长。《穿井得一人》体现了古今中外中的“中”和“古”。六单元四种体裁，这一课是寓言，短小精辟，趣味横生，能很好地激发学生的阅读兴趣。 《穿井得一人》是文言文，所以需要疏通文意。因为它短小而且浅显，课下注释比较详细，所以学生是可以通过看课后注释疏通文意的，这一点需要做，但可以不用花太多时间。本课还可以较好地激发学生的写作兴趣，改变学生害怕写作的现状。
部编版语文七年级上册《杞人忧天》说课稿
二：说教学目标由于这则寓言故事出自于三千年前的古代典籍《列子》，对初一的学生来说是有一定难度的，所以对于字词字音以及文章意思的翻译还是很有必要的，为初一的学生今后学习文言文积累字词以及学习的方法。疏通字词也能更好的理解文章内容便于分析人物形象，也为揭示文章的寓意起到关键的引导作用。再通过人物形象的分析结合故事背景引导学生多角度解读寓言的寓意，指出其现实意义以激发学生学习传统文化的兴趣。三:说教学重难点所以我的教学重难点第一是在疏通文意，第二就是在学生能通过引导多角度分析文章寓意并能很好的理解其现实意义，以培养学生多元化思考问题的能力以及对传统文化的热爱。四：说教学方法:考虑到我校初一的学生大多活泼开朗，好奇心强，所以在教学过程中以让那个学生合作探究自读自悟为基础，教师可以大胆放手让那个学生结合导学案以及课下注释探究感悟文章的意思，调动学生的积极性也培养学生自我学习的能力，并把诵读作为教学的重要手段，“书读百遍其义自见”不同形式的朗读能更好的促进学生的学习和感悟。
部编版语文七年级上册《女娲造人》说课稿
一、说教材1. 教材的地位与作用《女娲造人》选自义务教育课程标准实验教科书《语文》七年级上册第六单元。本单元的课文，都是想像极为丰富的作品。《女娲造人》是一则神话，通过本课的学习，使学生了解神话的特点，了解原始先民关于人类起源的极富想像力的解释，培养学生丰富的想像力，引导学生理解女娲身上所寄托的人类母亲的优秀品质，感受人类诞生后的欢欣与愉快。2. 教学目标新课程理念下的语文教学应当是以学生发展为本，培养能力为重，同时关注学生的情感、态度和价值观，所以根据本课内容确定以下三个方面的目标。①知识目标：掌握神话的特点，体会想像在神话创作中的作用，了解原始先民关于自身起源的极富想像力的解释，激发学生探求未知领域的欲望――追寻人类起源。
人教版高中语文必修3《过秦论》说课稿3篇
本文篇幅较长，并且有一字句不易理解，因而对高一学生来说完全读懂内容有一些困难。这样的话，老师就要做好引导工作，把一些难点，或是出现词类活用比较多，局势比较特殊的句子，老师可以先给学生画出来，存疑，或是与同学们一起讨论解决。对那些不易懂的字词就引导学生联系上下文提供的语境、前后涉及的情节加以推测、判断，以培养学生依据文脉推断词义的好方法。要求学生点出重点实词、框出通假字，主要是为帮助学生积累和掌握一些文言文中常见的一词多义、异读现象、古今异义和通假现象的词语，并进一步得出规律，指导今后的文言文学习。词类活用和特殊句式在文言文翻译中难度较大，也是本文教学的两大难点。要求学生标出有活用现象的字和划出句式特殊的句子，是基于两点考虑：1、积累一定数量的第一手例句；2、引导学生加以分类，找出每类的相同特征，并抽取出来形成规律性的东西，从而上升到理性认识，使学生能由学会一个到会学多个。翻译过程中注重指导学生养成用符号法表示重点字句的好习惯，如点、框、圈、划线等符号应约定一致，便于突出翻译中的重点、难点及复习。我的提示着重归纳了实词“制”“亡”“遗”“利”等，名词活用、形容词活用、使动用法，被动句、状语后置句。
人教版高中语文必修3《祝福》说课稿3篇
各位评委老师，大家好。我说课的题目是《祝福》。一、说教材（一）教材所处的位置和地位高中语文新课程教材必修五本书，共有2个单元中外小说单元。一个必修3的第一单元，一个是必修5的第一单元，共六篇文章。（《林黛玉进贾府》《祝福》《老人与海》《林教头风雪山神庙》《装在套子里的人》《边城》）《祝福》是属于前者。小说是拥有众多读者的一种文体，它可以多方面刻画人物性格，描摹人物心理，完整地表现人物之间的冲突，还可以具体生动地再现人物生活的环境，因此在反映复杂的社会生活方面具有独特优势。所以学习小说这种文学样式，也是有助于学生学会鉴赏小说的基本方法，为将来的小说阅读打下基础。鲁迅的《祝福》是中国现代小说的精品，当中的人物祥林嫂也是鲁迅小说中与阿Q、孔乙己三个最为出名的人物之一。研读好这篇文章，对将来小说的阅读，小说中人物的理解，甚至小说的写作都有深广意义。

f.有丝分裂的意义（讨论分析教学），首先引导学生结合所学知识讨论有丝分裂的的作用，最后有教师归纳总结，并要求学生在理解的基础上记忆。g.无丝分裂（图形直观教学、简介），本部分内容不是教学的重点，内容也相对简单，所以我的教学方法是直接给学生展示挂图，再进行简短介绍，让学生了解即可。h.引出减数分裂的概念，为第五章学习打下基础。小结：新课讲完以后由教师对本节内容进行总结巩固和反馈：进行一些课堂练习达到巩固和反馈的作用。最后布置作业，各种难度的作业题目均设置一些，其中简单题比重大，难题要求学生选作，这样提高学生学习积极性。2教学媒体程序设计: 细胞周期的概念（多媒体课件演示周期动画）植物细胞有丝分裂（多媒体课件演示分裂各期动画）动植物细胞有丝分裂异同点（多媒体课件演示分裂各期动画）有丝分裂过程中DNA和染色体数量的变化规律（挂图演示，包括表格和函数图象）
人教版高中政治必修1税收及其种类说课稿
在学生明确了税收的含义之后，我将分别对税收的三个基本特征进行解析。在讲解了之后，并分别用实例对其进行说明，加深学生对知识点的印象。最重要的是，总结出关键的字眼，使得学生能够清晰的区分出税收的三个基本特征。将强制性概括为依法征税、依法纳税；无偿性概括为不具有偿还性和返还型；固定性概括为规定应不应纳税、纳什么税、纳多少税。并跟学生指出，强制性是基本前提，无偿性是核心。由此根据书上的内容，推导出税收的三个基本特征相互之间的关系，即：三者缺一不可，统一于税法。而且，无偿性要求强制性，强制性保障无偿性；而无偿性与强制性又共同决定固定性。从而结束新课讲授。3、课堂总结根据板书内容重新回顾本课学习的主要内容，包括税收的含义，以及税收的三个基本特征和它们之间的相互关系。4、作业布置让学生预习税收的种类的内容，尤其是增值税和个人所得税。同时了解父母每月所缴纳的个人所得税和怎么计算的。
人教版高中政治必修3聚焦文化竞争力说课稿
（1）文化与经济、政治在经济基础上相互影响。①经济、政治和文化是社会生活的三个基本领域。其中，经济是基础，政治是经济的集中表现，文化是经济和政治的反映。一定的文化由一定的经济、政治所决定，又反作用于一定的政治、经济，给予政治、经济以重大影响。②经济发展是文化发展的基础。但这并不意味着文化的发展始终与经济的发展亦步亦趋。如同不能简单地把精神文明看作是物质文明的派生物和附属品一样，也不能简单地认为文化是经济、政治的派生物和附属品。文化有其自身的传承性和相对的独立性。那种认为只要物质条件好了，精神文化自然而然地就会好起来，物质条件差一点，精神文化就不可能搞好的观点，不符合历史发展的事实，是不正确的。③掀开历史的画卷，文化既有古今和地域之别，又有先进与落后、腐朽之分。不同的文化，对经济、政治的影响不同，对社会发展的作用也不同。不同民族的文化，影响不同民族和国家各具特色的发展道路。
人教版高中政治必修3体味文化说课稿
3、文化的力量。为了使学生能辨证地分析文化的力量，我设计了两个问题进行探讨：（1）是不是任何文化都能起促进作用？（2）你在听或唱国歌时感受到一种什么样的力量？这样，学生在对比中学会辨证地分析文化的力量——先进的、健康的文化能促进社会发展和个人成长；落后的、腐朽的文化则阻碍社会发展和个人成长。同时还能提高学生的文化赏析能力，从而引导学生装自觉参加健康有益的文化活动，抵制不良文化的影响，投身到社会主义精神文明建设中去。关于课堂练习，我准备了5个针对性比较强的选择题，从而加深巩固本框题的重难点知识。最后，播放歌曲《走进新时代》，展示本课知识结构，指出本框题需重点掌握的问题，结束本课教学。课后作业，我设计了这样一个辨析的题目：文化是人们创造的全部财富的总和，它是人类特有的现象。
