小学数学人教版二年级下册《用有余数的除法解决问题》说课稿
一、设计思路《数学课程标准》倡导尊重学生的主观能动性，以自主探究、合作交流为主要学习方式。因此，在本节课中我们充分体现了以学生为主体的设计理念，采用具有我校特色的高效课堂模式“三学五环”教学法，学生以“自主学习-合作探究”的方式进行学习，从而展示三学“独学、对学、群学”。在教学流程上以：“情境导入，引入示标；自主尝试；交流展示；精讲点拨；当堂检测”这五大环节来引领学生进入知识的殿堂。二、说教材充分领略教材编排意图，科学精当地分析文本，是采用“以学定教”，实现“有效教学”的第一步。《用有余数除法解决问题》是人教版小学数学二年级下册第67页的内容，它属于数与代数领域。本节课是在学生已经学习了表内除法、用竖式计算除法、有余数除法的基础上进行教学的。同时，本课为今后学习近似数、估算进行了初步的铺垫。
小学数学人教版五年级下册《异分母分数加减法》说课稿
重难点依据人教版数学教材新课程标准，在吃透教材的基础上，我确定了掌握异分母分数加减法的计算法则为教学重点，因为只有掌握了计算法则，才能进行计算。同时，也确定了理解异分母分数加减法计算时必须先通分的算理为教学难点。 二、说教法我们都知道数学是中国教育中一门必修学科，因此，从小学数学教学开始，就不仅要使学生“知其然”，还要使学生“知其所以然”。我们在以师生既为主体又为客体的原则下，展现获取理论知识、解决实际问题的思维过程。考虑到五年级学生的现状，我主要采取设置情景教学法，让学生积极主动地参与教学活动，使他们在活动中得到认识和体验，产生践行的愿望。当然老师自身也是非常重要的教学资源。教师本人应该通过课堂教学感染和激励学生，调动起学生参与的积极性，激发学生对解决实际问题的渴望，并且要培养学生理论联系实际的能力，从而达到最佳的教学效果。
小学数学人教版五年级下册《长方体和正方体的表面积》说课稿
一、教材分析长方体和正方体的表面积是人教版教材五年级下册第三单元第二章节的内容。本节课的地位和作用：这部分内容是在学生学习了长方体和正方体的认识以及掌握了长方形和正方形面积的计算方法的基础上进行教学。教材中各年级涉及到的内容如下：长方体和正方体的表面积这部分内容，是在学生认识并掌握了长方体和正方体特征的基础上教学的。教材为了使学生更好地建立表面积的概念，加强了动手操作，让每个学生拿一个长方体或正方体纸盒，沿着棱剪开，再展开，观察展开后的形状。并分别用“上”“下”“前”“后”“左”“右”标明6个面。这样，可以使学生把展开后每个面与展开前这个面的位置联系起来，更清楚地看出长方体相对的面的面积相等，以及每个面的长和宽与长方体的长、宽、高之间的关系，既让学生明确了表面积的含义，又为下面学习计算长方体和正方体的表面积做好了准备。
小学数学人教版五年级下册《容积和容积单位》说课稿
因此，我从学生已有的生活出发，寻找例子，帮助学生理解容积的概念。同时也多次提供了实践机会，让学生自己操作实验的过程，在操作中感知1升、1毫升的大小和容积单位和体积单位之间的关系。二、说教学目标1、理解容积的概念，认识常用的容积单位，感知1升和1毫升的实际大小，并掌握容积单位、体积单位间的进率。2、通过实验的方法，使学生经历探究容积单位、容积单位和体积单位之间的关系的过程。三、教学重难点：1、建立容积和容积单位概念，知道容积单位和体积单位的关系。2、会计算容积。四、说教法为了使课堂的主人能活跃起来，我用了自主探究式发现问题、谈论交流和实验教学的方法进行教学，从而也激发了学生的积极性和主动性。五、说学法：更多的是引导学生在自主尝试、观察、讨论和探究中获取知识。
小学数学人教版五年级下册《长方体和正方体的认识》说课稿
3.说教学重、难点依据数学课程标准，及对教材的认识，我确定了本节课的重点和难点。教学重点：掌握长方体和正方体的特征。教学难点：建立“立体图形”的空间概念，了解长方体、正方体的关系。二、说教法根据几何知识的教学特点、本节教学内容以及小学生空间观念薄弱的特点，我将采用以下教学方法。直观演示法：利用图片等手段进行直观演示，激发学生的学习兴趣；观察发现法：通过让学生观察长方体、正方体的一些实物发现新知，培养学生的观察概括能力；合作探究法：引导学生通过自主研究、合作讨论等活动形式来获取知识。同时运用多媒体辅助教学，使学生的观察能力、抽象概括能力逐步提高。三、说学法为了使学生较好地掌握长方体和正方体的特征，并逐步形成空间观念，除了让学生通过观察来认识长方体和正方体的特征以外，在观察实物的基础上，通过动手操作，看一看，摸一摸，数一数，量一量，做一做来学习新知，同时以此来激发学生的学习兴趣，调动学生的积极性。
小学数学人教版五年级下册《同分母分数加减法》说课稿
1、教材分析《同分母分数加减法》是人教版五年级下册第五单元的内容。本节教学内容包括分数加减法的含义、同分母分数加减法的计算方法和连加、连减三个部分。这部分内容是在学生学习整数、小数加减法的意义及其计算方法，分数的意义和性质，以及在三年级上册学过的简单的同分母分数加减法的基础上进行教学的。为异分母分数加减法的学习搭好阶梯。2、学情分析相对整数加减运算而言，分数的加减运算对于大多数学生来说是比较困难的，但是学生对简单的同分母分数加减法计算有一定基础。学生已有一定的生活经验，并有一定的分析和解决问题的能力，会有条理地表达自己的思考过程。3、教学目标(1)知识与技能：掌握同分母分数加减法的计算方法，理解相同单位的数相加减的算理及含义，并能够正确熟练地计算。(2)过程与方法：能够利用所学知识解决生活中的实际问题，培养学生应用知识的能力。(3)情感态度与价值观：通过小组合作学习，培养学生的合作意识和学好数学的信心。

人教版新课标高中物理必修2生活中的圆周运动教案2篇
思考：洗衣机脱水时转速高时容易甩干衣物，还是转速低时容易甩干衣物？(2) 制作棉花糖的原理内筒与洗衣机的脱水筒相似，里面加入白砂糖，加热使糖熔化成糖汁。内筒高速旋转，黏稠的糖汁就做离心运动，从内筒壁的小孔飞散出去，成为丝状到达温度较低的外筒，并迅速冷却凝固，变得纤细雪白，像一团团棉花。5.离心现象的防止在水平公路上行驶的汽车，转弯时所需的向心力是由车轮与路面的静摩擦力提供的。如果转弯时速度过大，所需向心力F大于最大静摩擦力Fmax，汽车将做离心运动而造成交通事故。因此，在公路弯道处，车辆行驶不允许超过规定的速度。当高速转动的砂轮或者飞轮内部分子间相互作用力不足以提供所需向心力时，离心运动就会使他们破裂，甚至酿成事故。
人教版新课标高中物理必修2机械能守恒定律教案2篇
（二）进行新课1、动能与势能的相互转化演示实验1：如右图，用细线、小球、带有标尺的铁架台等做实验。把一个小球用细线悬挂起来，把小球拉到一定高度的A点，然后放开，小球在摆动过程中，重力势能和动能相互转化。我们看到，小球可以摆到跟A点等高的C点，如图甲。如果用尺子在某一点挡住细线，小球虽然不能摆到C点，但摆到另一侧时，也能达到跟A点相同的高度，如图乙。问题：这个小实验中，小球的受力情况如何？各个力的做功情况如何？这个小实验说明了什么？学生观察演示实验，思考问题，选出代表发表见解。小球在摆动过程中受重力和绳的拉力作用。拉力和速度方向总垂直，对小球不做功；只有重力对小球能做功。实验证明，小球在摆动过程中重力势能和动能在不断转化。在摆动过程中，小球总能回到原来的高度。可见，重力势能和动能的总和保持不变。即机械能保持不变。
