北师大版小学数学五年级上册《找因数》说课稿
【设计意图：让学生在操作、探索的基础上，组内交流想法，再在班内交流汇报，让学生的语言得到相互交流、碰撞，从而不断激发学生的思维火花。】师：你能把这些摆法用算式写出来吗？（学生独立写出算式并汇报）依学生汇报板书：1×12=122×6=1212×1=126×2=123×4=124×3=12师：请同学们观察一下，哪两道算式的因数一样？学生观察算式，找出因数一样的算式。师：那么，这6个算式最少能用几种算式表示出来？引导学生说出能用3种方法表示，这三种方法是：1×12=122×6=123×4=12，并指明算式一样时选择其中一种说出来。板书：12=1×12=2×6=3×4师：同学们观察一下，12的因数有哪几个？（学生说出12的因数有：1、12、2、6、3、4。）师：拼长方形与找因数有什么关系呢？(指名学生说一说)师：根据刚才的操作交流，请同学们说一说怎样找一个数的因数呢？（学生思考片刻后汇报，可以组内交流。）引导学生说出：用乘法思路想，看哪两个数相乘得12，然后一对一对找出来。
北师大版小学数学五年级上册《找质数》说课稿
第一：说教材。“质数和合数”是九年义务教育小学数学五年级（上）第三单元的内容，在教材第39~40页；是学生学习了因数和倍数的意义，了解了2、5、3倍数的特征之后的重要知识，它是学生学习分解质因数、求最大公约数和最小公倍数的基础，在本章教学中起着承前启后的重要作用。第二：说教法:根据新课标的精神和学生实际，我将本节课教学目标定为：1）找因数填表格经历探索质数与合数的过程，理解质数与合数的意义；2）能正确判断一个数是质数或合数；3）在研究质数的过程中丰富对数学发展的认识，感受数学发展的文化魅力；4）、在猜想——验证——概括——理解的过程中体会学习数学的乐趣，积累数学学习的方法。第三：说教学重难点重点：理解质数与合数的意义。难点：能正确判断一个数是质数还是合数，体会数学学习的方法。教学准备：课件教学安排：两课时。
北师大版小学数学五年级下册《倒数》说课稿
教学目标：1、引导学生通过计算、比较、观察、等实践活动，使学生理解倒数的意义，掌握求倒数的方法，并能正确熟练的求出倒数。2、通过自主探究、合作交流的方式培养学生与人合作的能力。3、提高学生学习数学的兴趣，发展学生质疑的习惯。教学重点：知道倒数的意义和会求一个数的倒数教学难点：1、0的倒数的求法。二、说教法基于教材内容比较单调，那么只有在教法上体现新、奇、特，才能让学生想学、要学。在教学过程中，我将始终扮演一个组织者、引导者、合作者的角色，根据小学生从具体的形象思维逐步向抽象的逻辑思维发展的思维特点，联系小学生熟悉的身边实际，使抽象的内容直观化，激发学生的学习兴趣，引导学生去发现问题、讨论问题，放手让他们自主探究和合作交流，帮助他们在自主探究、合作交流中真正理解并掌握本节课的数学知识、技能、思想和方法。
北师大版小学数学六年级下册《变化的量》说课稿
1、结合具体情境，体会生活中变化的量，感觉变化的量之间的关系，认识变化特征。2、通过自主探究，合作交流，在活动过程中培养学生用多种方法解决问题的能力，进一步发展学生观察、比较、概括等能力，渗透分类的数学思想。3、经历数学活动的过程，体验用多种方法研究问题的乐趣，感觉成功的快乐，增强学好数学的信心。教材安排了多个生活情境，以表格、图像、关系式等不同方式呈现，目的是让学生通过多种方式认识变化的量的特征。因此，我确定本课的教学重点是结合具体情境，感觉变化的量之间的关系，认识变化特征。六年级的学生，抽象思维得到了一定的发展，但以前从未接触过变化的量，从之前熟悉的定向思维模式转向多向思维模式，并认识变化特征会有一定的困难。因此，我确定本课的教学难点是用多种方式认识变化的量的变化特征。本课需要教师准备多媒体课件，为学生准备学习单。
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。
北师大版小学数学六年级下册《面的旋转》说课稿
2．放大空间，升华思考由于我对教材的二度开发留给了学生足够的探索空间，课上学生探索数学的热情被充分调动，我们欣喜地看到：有的学生尝试着不同平面图形的旋转；有的学生只用一种平面图形，却旋转出不同的立体图形；有的学生的思维并没有停留在表象上，而是在深入地思考产生这一现象的原因……交流时学生的发现远远超出了我们的想象，这份生成带给我们的是惊喜，是赞叹，更是“以操作促思考”的教学行为结出的硕果。3．巧用课件，形成表象本节课，我充分运用现代信息技术将平面图形经过旋转形成立体图形的过程生动、逼真地再现出来，帮助学生将抽象的空间想象化为直观，进而形成表象，深植于学生的脑海中，促进了学生空间观念的形成。总之，在这节课上，我坚持把“促进学生发展”作为第一要素贯穿于课堂教学的始终，让学生在充满着民主、探究、思考的氛围中，积极操作、主动思考，发展了学生的空间观念。
北师大版小学数学六年级上册《合格率》说课稿
四、说教法、学法我在教学中主要采用的教学方法是先学后教中的“两学两教”。辅之以多媒体教学手段（主要通过微课视频的观看学习）。本课学生的学习方法主要有：自主发现法、合作交流法、自学尝试法等。1.学生在自主探究解答例题，求两种品牌罐头的合格率时，主要采用自学尝试法，根据知识的迁移，学生能够正确求出产品合格率。2.在总结小数、分数化成百分数的方法时，学生主要采用自主发现，合作交流的方法。首先让学生观察例题板书，想一想怎样把小数、分数化成百分数，采用了“兵教兵”的方法，达到了人人参与的目的。当然，由于学生所处的文化环境，家庭背景和自身思维方式的不同，不同的学生所采用的方法也不尽相同，作为教师要尊重学生的选择，允许学生用自己喜欢的方式学习数学。五、说教学过程
北师大版小学数学六年级上册《圆的认识》说课稿
④联系生活实际解决身边的问题，让同学初步感受数学与日常生活的密切联系，体验数学的应用，促进学生的发展。接下来，我再具体谈一谈这堂课的教学过程。3、说教学过程第一环节：创设情境，激qing导入。同学们你们看屏幕上的是什么？（出示图片）那么自行车车轮是什么形状的？为什么车轮要设计成圆形？这里面有什么奥妙呢？学了今天的内容大家就会明白的。这节课我们就走进圆的世界去探寻其中的奥妙。板书课题：圆的认识设计意图：通过生活中实际例子引入课题，一方面引起学生的学习兴趣，另一方面为学习新知识做了铺垫，从思想上吸引了学生主动参与学习的活动。这一环节的设计，主要是想体现数学就在我们的身边，从而激发学生学习的兴趣及学习的积极性。

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。
