北师大版小学数学三年级下册《找规律》说课稿
（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。
北师大版小学数学四年级下册《方程》说课稿2篇
3、变换角度，深入思考第三幅情境图隐含着多样的等量关系，也正是引发学生数学思考的最佳情境。根据学生认识的深入程度，可适当让学生体会到等式的“值等”和“意等”，并放手让学生探究，根据不同的认识找到不同的等量关系，列出等量关系不同的同解方程。在教学中，先引导孩子发现情境中的基本相等关系：2瓶水的水量+一杯水的水量=一壶水的水量，并且列出等式2z+200=2000，在此基础上，再引导孩子发现其他的等量关系。在这一过程中，充分激发孩子探求知识的欲望，调动孩子思考的主动性和灵活性，从而找到多样化的等量关系，并进一步提高孩子解决数学问题的能力。4、建立概念，判断巩固在前面教学的基础上总结、抽象出方程的含义。通过三道例题的简洁数学式子表达，让小组合作寻找他们的共同特点，从而建立方程的概念。“含有未知数”与“等式”是方程概念的两点最重要的内涵。并通过“练一练”让学生直接找出方程。
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《反比例》说课稿
知识与能力目标是：理解反比例的意义，能判断两个量是不是成反比例过程与方法目标是：通过讨论、探究、观察等活动，提高分析问题解决问题人的能力情感态度价值观目标是：培养学生对学习数学的兴趣，感知数学与生活的联系。此外，根据我对教材的解读，我将本节课的教学重点确定为：理解反比例的意义教学难点确定为：判断两个量是不是成反比例二、教法与学法新课标指出：学生是学习的主体，教师是学习的组织者、引导者和合作者，因此首先我采用情境教学法，通过创设情境，激发学生对学习数学的兴趣，；再通过师生互动，探究式教学，为学生创设一个宽松的数学学习环境，相对教师的教法学生采用自主探索，研讨发现的学习方法，让学生成为学习的主人，发挥学生学习数学的积极性和主动性，最后利用练习法：通过适当的练习，巩固所学的知识，解决生活中简单的实际问题
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。
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
