北师大版初中数学八年级下册等腰三角形说课稿2篇
一、说教材：等腰三角形是北师大版初中八年级下册数学教材第一章第一节的教学内容，本节是轴对称图形的应用，是研究等腰三角形的开篇。通过本章节的学习，可以丰富和加深学生对已学图形的认识，为以后的图形学习和证明打好基础。本节在编排上考虑学生的认知规律，从学生容易接受的动手操作找规律开始到几何画板的验证再过渡到几何证明与应用。根据课程标准，确定本节课的目标为：【教学目标】1.知识与能力 理解并掌握等腰三角形的定义，探索等腰三角形的性质；能够用等腰三角形的知识解决相应的数学问题．2.过程与方法通过动手操作、动态演示等方法，培养学生思考探究数学的能力；通过例题与练习，提高学生添加辅助线解决问题的能力。3.情感、态度与价值观 在探索等腰三角形性质的过程中体会轴对称图形的美，感受数学与生活的联系；在例题教学中，感受数学之美；培养学生分析解决问题的能力，使学生养成良好的学习习惯．
北师大版初中数学八年级下册分式的加减法说课稿2篇
一、说教材《分式的加减法》是本册教材第三章《分式》重要内容，是进一步学习分式方程、反比例函数以及其它数学知识的基础，同时也是学习物理、化学等学科不可缺少的工具。与其它数学知识一样，它在实际生活中有着广泛的应用。学习分式的加减法并熟练地进行运算是学好分式运算的关键，为学生综合运用多种运算法则拓宽了空间，有利于学生对双基的掌握，在综合运用多种运算法则的过程中，逐渐形成运算能力。同时本节课的教学难度有所增加，学生通过观察、类比、猜想、尝试等一系列思维活动中，发现规则、理解规则、应用规则。考虑到以上这些因素，确定本节课的目标和重点、难点如下：（一）说教学目标：1.知识与技能目标：理解并掌握异分母分式加减法的法则；经历异分母分式的加减运算和通分的过程，训练学生的分式运算能力，培养学生在学习中转化未知问题为已知问题的能力；进一步通过实例发展学生的符号感。
北师大版初中数学八年级下册分式方程说课稿
设计意图：考虑学生的个别差异，分层次布置作业，让基础差的学生能够吃饱，基础好的学生吃好，使每位学生都感到学有所获。五、评价分析数学课程标准指出：学生的数学学习内容应当是现实的、有意义的、富有挑战性的，而动手实践、自主探究与合作交流是学生学习数学的重要方式。本着这一理念，在本课的教学过程中，我严格遵循由感性到理性，将数学知识始终与现实生活中学生熟悉的实际问题相结合，不断提高他们应用数学方法分析问题、解决问题的能力。在重视课本基础知识的基础上，适当进行拓展延伸，培养学生的创新意识，同时根据新课程标准的评价理念，在教学过程中，不仅注重学生的参与意识，而且注重学生对待学习的态度是否积极。课堂中也尽量给学生更多的空间、更多展示自我的机会，让学生在和谐的氛围中认识自我、找到自信、体验成功的乐趣。使学生的主体地位得到充分的体现，使教学过程成为一个在发现在创造的认知过程。
北师大版初中数学八年级下册认识分式说课稿
回顾整节课的设计，我主要着力于以下三个方面：1.关于教材处理：认真处理教材，目的只有一个——为我的学生尽可能多地提供参与活动的机会，在本节课中主要体现在以下几点：（1）通过“合成代数式”、“赋予分式实际意义”两个活动，激发兴趣，吸引学生参与活动；（2）通过“互举例子”、“填表探究”两个活动，鼓励学生主动参与活动；（3）通过“应用新知”这个环节，促进学生参与活动。2.关于教与学方法的选择：我在设计中始终关注：如何精心组织活动，让学生在丰富的活动中探索、交流与创新，因此我选择了“引导——发现教学法”，具体做法如下： （1）用数、式通性的思想，类比分数，引导学生独立思考、小组协作，完成对分式概念及意义的自主建构，突出数学合情推理能力的养成；（2）加强应用性，通过“应用新知”、“深化拓展”两个环节，密切分式与现实生活及其他学科的联系，发展数学应用意识，突出分式的模型思想。
北师大版初中数学八年级下册提公因式法说课稿
设计目的：通过学生的反馈练习，使教师能全面了解学生对公因式概念的理解是否到位，提取公因式的方法与步骤是否掌握，以便教师能及时地进行查缺补漏．但依然有部分同学会出现问题，如对首项出现负号时不能正确处理，此时，需要老师进一步引导．第四环节 课堂小结从今天的课程中，你学到了哪些知识？你认为提公因式法与单项式乘多项式有什么关系？怎样用提公因式法分解因式？设计目的：通过学生的回顾与反思，强化学生对确定公因式的方法及提公因式法的步骤的理解，进一步清楚地了解提公因式法与单项式乘多项式的互逆关系，加深对类比的数学思想的理解。第五环节 当堂检测把下列各式分解因式（1）2x2-4x (2)8m2n+2mn(3)-4a3b3+6a2b-2ab (4)2n2-mn-n＊(5)3an+1-2anc-7an+2设计目的：检验学生的目标达成情况，其中第五小题供学有余力的学生选作。第六环节 课后反思教学反思
北师大版初中数学八年级下册图形的平移说课稿
1、数数格子，认清方向（完成想想做做第1题）设计意图：本题在于让学生认清平移的方向和距离，感受平移的不同方法。在教学中，让学生自己独立思考完成，自由发言。鼓励学生说出不同的平移方法。2、小试牛刀（完成想想做做第2题）设计意图：本题主要是让学生掌握按要求画平移后的图形。这是本节课的难点。在教学中，先让学生独立画图，教师巡视作图情况，对有困难的学生给予指导。在学生完成作图后，投影部分学生的作品，交流平移的过程与方法。最后在多媒体课件上展示画法。.3、平移的运用(“想想做做”第3题)设计意图：本题在于使学生学会运用平移的知识画平行线，体会平移的价值。（四）课堂小结，升华提高提问：今天你有哪些收获?设计意图：以问题为载体，引领学生对本节课的归来总结。让学生再次理解图形的斜向平移可转换成横向平移和竖向平移。
北师大版初中数学八年级下册平行四边形的性质说课稿2篇
注意：平行四边形中对边是指无公共点的边，对角是指不相邻的角，邻边是指有公共端点的边，邻角是指有一条公共边的两个角．而三角形对边是指一个角的对边，对角是指一条边的对角．（教学时要结合图形，让学生认识清楚）设计意图：通过观察图片和回顾以前的知识，使学生由感性认识上升到理性认识。通过描述平行四边形的特点和定义，也培养了学生的语言表达能力。同时也渗透了一些由实际问题转化为数学问题的“转化”的数学思想。（三）、引导实验探索新知【探究】平行四边形是一种特殊的四边形，它除具有四边形的性质和两组对边分别平行外，还有什么特殊的性质呢？我们一起来探究一下．动手操作并思考：让学生根据平行四边形的定义画一个一个平行四边形，观察这个四边形，它除具有四边形的性质和两组对边分别平行外以，它的边和角之间有什么关系？度量一下，是不是和你猜想的一致？
人教版新课标PEP小学英语五年级上册What Can You Do说课稿8篇
目的是让学生更深入理解Just do it的意思，能在一定情景中运用。接下来出示一些山羊妈妈的动物朋友引出课文内容。让学生先观看课文的视频，这样更生动些，也许也能更引起学生的兴趣些，因为这是一堂相对比较枯燥的读写课，有了视频观看可能更生动和有趣些。通过完成课文填空和课后回答问题，让学生既练习到写，又练习到对课文的理解，之后再让学生演一演深入课文的朗读。在最后一环节再让学生完成一个new dialogue的填空运用。这样使整堂课更完整些，学生再一次运用所学知识得到拓展。What Can You Do? PaRT B 第二课时说课稿一、教材分析1.教学内容本课主要学习有关家务劳动的表述，主要句型有：Can you ……?Yes ,I can No, I can’t .本课时的大部分动词词组在四年级上下册中都已出现过。如：Water the flowers ,sweep the floor ,set the table.2.教学目标。（1）语言技能与知识目标通过本课的学习，能够询问别人能做什么家务。如：Can you set the table ?（2）运用能力目标会用Can you…?语句询问并作出肯定或否定回答。

第一环节：教师参与到其中的一个小组，用“Do you like…？”的句型提问，因为学生在上学期已经接触了“like”一词，现在又有了前面三次听的机会，对本课所要学的对话有了一定的感知，预计有部分学生会回答“Yes，Ido.或No，I don’t .”当学生回答“Yes，Ido.”时，我就说：“Here you are .”同时也将水果递给学生。在教师与学生、学生与学生的对话中，领悟了“Yes，Ido.”和“Here you are .”的意思。当学生回答“No, I don’t.” 时，教师不把水果递给他。通过这个过程的口语与演示，学生也会领悟到“No, I don’t.”的意思。同时，进行师问生答的口语操练。师生对话要适当增加，使学生对“Yes，Ido.和No, I don’t”的句型有更多的操练机会。这样，第一环节的目标也就达到了。第二环节：由师问生答的形式，变为生问师答。通过教师引导，让学生用“Do you like …”提问。因为，学生要把“Do you like …”的音读准，有一定难度。因此，在起先学生说这句式时，要发挥教师的主导作用，让学生跟读，注重学生发音的准确。
