北师大版小学数学四年级下册《猜数游戏》说课稿
1、说教材：本节课是北师大版小学数学四年级下册第94-95页。猜数游戏是在学生已经学习了用字母表示数、方程、等式的性质等知识的基础上进行学习的。本节课主要学会用等式的性质解“ax±b=c”这样的方程，并能用方程解决简单的实际问题。教材通过笑笑和淘气猜数游戏，利用等量关系列出方程，重点是利用等式的性质解方程，能口头检验，形成检验的意识。本节课我通过游戏激发学生的兴趣，使学生体会方程的作用，并产生学习方程解法的愿望，为以后学习解方程、用方程思想解决问题打下重要基础。2、说教学目标：通过猜数游戏的这个情景，让学生会解形如“ax±b=c”的方程，并会简单应用，让学生在此过程中，体验解方程的思路，并掌握方法。在情感、态度、价值观方面，通过游戏，训练学生的数学思维能力，养成善于思考的习惯。3、说重、难点：本节课的重点是会解形如“ax±b=c”的方程，并会简单应用；难点是利用等式的性质解方程

（三）、巩固反馈师：同学们的表现真的令我出乎意料，你们太聪明了，今天我就带大家去数学王国去参观，敢去吗？如果你们能闯关成功就可以免费进入王国的游戏宫，有信心吗？（激励学生，让同学们很快进入巩固练习这个环节中来）第一关：逛同学恩喜爱的食品店（这一关的设计采用抢答的方式进行，更进一步激发学生的学习兴趣，而且巩固了本课重点——计算规律。）第二关：我们来到了你们的妈妈喜欢服装店（这一关先让学生独立尝试，并抽生板演，全班订正，注意强调答语的写法。）第三关：现在我们来到了养鸡场。（这一关仍然采用抢答的方式进行，这道题目主要考察同学们对第二条规律的掌握情况）第四关：进入数学王国继续玩抢答游戏和猜一猜活动（这个环节让学生体会到学习的乐趣）
北师大版小学数学六年级下册《正比例》说课稿
{二}、努力实现扶与放的和谐统一，共同构建有效课堂。学生能自己解决的决不包办代替：学生可能完成的，充分相信学生，发挥自主探索与合作交流的优点，让学生有一个充分体验成功展示自我的舞台；学生有困难的，给予适当引导，拒绝无效探究，提高课堂效率。四、教学目标：基于对教材的理解和分析，我将该节课的教学目标定位为：1、帮助学生理解正比例的意义。用字母表示变量之间的关系，加深对正比例的认识。2、通过观察、比较、判断、归纳等方法，培养学生用事物相互联系和发展变化的观点来分析问题，使学生能够根据正比例的意义判断两种量是不是成正比例。3、学生在自主探索，合作交流中获得积极的数学情感体验，得到必要的数学思维训练。
北师大版小学数学四年级上册《数一数》说课稿
亿以内数的认识，是在学生认识和掌握万以内数的基础上学习的。生活中大数广泛存在，对大数的认识是万以内数的认识的拓展，也是学生必须掌握的最基本的数学基础之一。本册教材先教学亿以内数的读法和写法，再教学亿以上数的读法和写法，并对数的理论进行整理，在两部分认识数教学中间安排十进制计数法，知道数位，数级，对亿以内数的认识的内容进行归纳整理，也对亿以上数的认识起承上启下作用。加强了数学与现实生活的联系，同时对学生进行综合知识的渗透，从万以内数的认识到亿以内数的认识是学生数概念的又一次扩充。教材提供了较丰富的素材，让学生感受大数，不仅为学生认识大数提供丰富的内容，也为对学生进行国情教育提供了好素材。突出数概念教学，从数学的高度把握十进制原理，培养数感。教学内容的呈现给了学生自主探索和自主交流的空间，也为教师组织教学提供了思路，如：读、写数的法则教材上不给出现成的结论，而是让学生通探究自主过讨论得到。
北师大版小学数学四年级下册《包装》说课稿
《包装》是北师大版四年级下册第三单元第四课时的内容。本课主要让学生探索小数乘小数的竖式计算方法，是在学生掌握小数点位置的移动引起小数大小变化的规律以及积的小数位数与两个乘数的小数位数之间关系的基础上教学的。小数乘法的竖式计算是本单元的重点，是学生正确进行小数乘法计算的关键。课本首先安排了三个问题：第一个问题是结合解决实际问题的过程，会选择适当方法估计运算结果，发展数感，并通过交流进一步理解小数乘法与整数乘法之间相互转化的条件；第二个问题也是结合解决实际问题的过程，掌握小数乘法转化为整数乘法进行运算的一般步骤，从而归纳总结小数乘法的竖式计算方法；第三个问题是经历独立计算和交流小数乘法的过程，体验算法的多样化，发展运算能力。其次安排了6道练习题，目的是为了进一步发展数感，巩固小数乘法的竖式计算方法，体会小数乘法的竖式计算在生活中的应用。
北师大版小学数学四年级下册《蚕丝》说课稿
三、说教学重点、难点重点是小数乘法的竖式计算方法和积与乘数的大小关系。难点是小数乘法中乘数末位有0的计算。四、说学情在进行本节内容学习之前，学生已经学习了整数乘法的运算规律，小数的意义及其加减法，还有小数乘法的计算规律。本节内容重点是学会把小数乘法的运算方法应用到解决实际问题中去。根据四年级学生的认知特点和课堂注意力时间有限的特点，在教学中一定要提高课堂效率五、说教法、学法在本课教学中，我采取的教学方法是：1.通过复习，回顾计算规律，并把它应用到竖式中去。2.情境展示，把数学问题直接放在实际问题中来学习并解决。3.解决问题时采用自主探索、独立思考和小组合作交流的学习方式。通过这些教学法激发学生学习的积极性和主动性，引导学生把学到的规律应用到现实生活中来解决实际问题。六、说教学过程（一）举例说明积的小数位数与乘数小数位数的关系。通过比眼力，做一做，复习前一节课所学内容，为本节课打下基础。
北师大版小学数学五年级上册《除得尽吗》说课稿
尊敬的领导，评委老师：大家好，今天我说课的题目是北师大版小学数学五年级上册第一单元第五节《除得尽吗》。我将会以说教材、说学生、说教法、说教学过程、说教学效果评测、说反思等六各方面进行我的说课。一：说教材《除得尽吗》本节内容是本单元的第五节，是在学生已经学习了整数除整数、整数除小树、小树除小数、以及四舍五入保留若干位小树的基础之上进行设置的。本节内容的主要知识点就是让学生认识循环小数、表示循环小数以及“四舍五入”法取其近似值，总体难度不大。二：说学生对于五年级学生而言，已经在四年级学习了“四舍五入”法，所以在本节新授教学中已经有了一定的基础。对于教师的教和学生的学都有了一定的促进作用。
北师大版小学数学五年级上册《约分》说课稿
课程标准中明确指出：“小学数学的教学内容绝大多数可以联系学生的生活实际，找准每一节教材内容与学生生活实际的“切入点”可让学生产生一种熟悉感、亲切感“，以及“数学教学活动中，教师应向学生提供充分从事数学活动的机会，帮助他们在自主探索的过程中真正理解和掌握基本的数学知识与技能。”要将这个理念落实在课堂教学中，就要求教师能根据教学的具体内容，选择恰当的学习方式，并巧妙创设学生主动探索的机会，变“接受学习”为“创造学习”，让学生在观察、操作、讨论、交流、归纳、整理、概括的过程中学习新知，充分以学生为主体，逐步培养学生的创新意识，形成初步的探索和解决问题的能力。根据以上思想，本节课的设计我主要从尊重学生已有的知识经验；在观察与操作中去亲身体验知识的形成过程，掌握约分的方法。
北师大版小学数学六年级下册《画一画》说课稿
一、教材：《画一画》这一内容是在学生学习了《变化的量》和《正比例》这两节内容以后安排的，学生已经结合大量的生活情境认识了生活中存在的许多相互依赖的变量，而且体会了这些变量之间的关系，认识了正比例及其意义，能初步判断两个相关联的两是不是成正比例，感受了正比例在生活中的应用，学生对正比例的认识有了一定的基础。教材安排这一内容，一是让学生进一步认识正比例，以及正比例中两个相关联的量之间的关系；二是通过让学生在方格纸上描出成正比例的量所对应的点并能在图中根据一个变量的值估计它所对应的变量的值，从而认识正比例图像的特点。主要意图是引导学生运用已有的知识，用图的形式去直观表示两个成正比例的量的变化关系，鼓励学生发现当两个变量成正比例关系时，所绘成的图像是一条直线，在此基础上，鼓励学生利用图，进行一些估计，解决一些问题，为以后进一步学习正比例函数打下一定的基础。
人教版高中生物必修2染色体变异说课稿
四、说教学程序（一）.温故知新、导入新课复习提问:基因突变导致生物变异的原因是什么?回答:基因突变是基因结构发生改变，从而使遗传信息改变，使蛋白质结构改变、生物性状改变，即生物发生了变异。那么，基因是什么?它和染色体又有何关系?回答:基因是有遗传效应的DNA片断，染色体是DNA的载体，基因在染色体上呈线形排列。引出新知:对于一个生物体来说，正常情况下，其染色体的结构和数量都是稳定的。但在自然条件或人为因素的影响下，染色体的结构和数量均会发生改变，从而导致生物性状的改变，这就属于染色体变异。（二）.把握重点、突破难点重点的把握：1、染色体结构的变异播放影片:猫叫综合征幼儿。让学生观察: 患儿哭声轻、音调高，很像猫叫。教师补充: 患儿的征状---两眼较低、耳位低下，存在着严重的智力障碍。阐述病因---染色体片段缺失

人教版高中英语必修4A taste of English Humor说课稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

人教版高中地理必修2煤城焦作出路何在说课稿
分析过焦作市的地理概况和产业优势后，就需要针对由于资源枯竭所带来的问题提出合理化的建议。既然是谈经济转型，就应该将话题的范围明确在这一领域内。通过材料3的相关内容，我们了解到焦作市需要在产业结构调整、培育新的优势产业、增强综合竞争力等三个整改方针上下功夫。因而引导学生针对优势与不足提出建议，以三个整改方针为基准，衡量建议的可行性是锻炼学生解决此类问题的有效途径。在此我将教会学生的是解决问题方法而非案例的内容，正所谓“授之以鱼，不如授之以渔”。接下来针对学生的建议和教材资料分析所罗列的10点整改思路，由学生自由发言提出看法，通过教师的指导和学生的讨论，进而确定经济转型建议的具体方案。最后注意将建议与产业优势相对照，看建议是否都是围绕着产业优势而提出的，这样做会加深学生的印象，通过建议和优势的对应关系，将不难找出此类问题的解题思路。
