人教A版高中数学必修二简单随机抽样教学设计
知识探究（一）：普查与抽查像人口普查这样，对每一个调查调查对象都进行调查的方法，称为全面调查（又称普查）。 在一个调查中，我们把调查对象的全体称为总体，组成总体的每一个调查对象称为个体。为了强调调查目的，也可以把调查对象的某些指标的全体作为总体，每一个调查对象的相应指标作为个体。问题二：除了普查，还有其他的调查方法吗？由于人口普查需要花费巨大的财力、物力，因而不宜经常进行。为了及时掌握全国人口变动状况，我国每年还会进行一次人口变动情况的调查，根据抽取的居民情况来推断总体的人口变动情况。像这样，根据一定目的，从总体中抽取一部分个体进行调查，并以此为依据对总体的情况作出估计和判断的方法，称为抽样调查（或称抽查）。我们把从总体中抽取的那部分个体称为样本，样本中包含的个体数称为样本量。

人教版高中政治必修1第二课多变的价格教案
（四）反思总结，当堂检测。本节内容讲述了价格变动对人们生活、生产的影响作用，主要知识框架如下：（1）、价格变动会影响人们的消费需求，商品价格上涨，人需求就减少，反之，则增大。价格变动对不同商品需求影响程度是不一样的，对生活必需品的需求量影响较小，对高档耐用品的需求量影响较大。相关商品价格变动对消费需求的影响不同，某种商品价格上涨，就会减少需求量，其替代品需求量增加，其互补品需求量则减少。（2）、价格变化也会影响生产经营，价格变动会调节生产，刺激生产者改进技术，提高劳动生产率，促使生产者生产适销对路的高 质量产品。（五）发导学案、布置预习。预习第三课第一框《消费及其类型》，完成预习导学案练习题九、板书设计《价格变动的影响》1、对人们生活的影响（1）商品价格变动与消费需求量之间的关系（2）不同商品的需求量对价格变动的反应程度不同

小学数学人教版二年级下册《克和千克》说课稿
[教材分析]本课时是《克和千克》这一单元的第一节课，主要介绍一些普通生活用品的重量认识质量单位克和千克，培养学生用数学观点发现克和千克两个质量单位，为进一步学习有关克和千克之间的联系做好准备。[学情分析]对于活泼好动的二年级孩子来说，物体的重量他们有一定的生活体验，同时，二年级学生形象思维能力较强，可以利用他们对身边物体质量来认识克和千克。有了以上的认识，我将本节课的教学目标拟定为：[目标定位]1、知识目标：让学生在生动活泼的情境中初步认识克和千克，建立克和千克的观念，知道1000克=1千克2、能力目标：培养学生初步的观察、操作能力，让学生学会看秤培养动手能力。3、情感目标：培养学生自主探索的精神和增强生活意识。教学重难点：通过活动正确认识克和千克的关系，知道1克和1千克的关系，难点建立克和千克的意识。
北师大版小学数学二年级下册《搭一搭》说课稿
（1）课件显示搭正方形的画面以及问题“4根小棒搭一个正方形，13根小棒可以搭多少个正方形，还剩几根？”。（2）组织小组讨论：有13根小棒，能搭几个正方形？请每个同学利用学具摆一摆，再依据上节课学习的除法算式，小组内讨论用竖式怎样表示。【设计意图：通过摆小棒搭正方形和自主探究等开发学生思维，促进学生多层次思考，培养孩子良好的思维方式，推动学生积极思考，逐步开阔学生解决问题的思路，培养学生横向思维能力。】（3）进行全班交流。指名回答；引导学生探究竖式各数表示的意思及单位名称的写法，并进一步认识余数。课件显示搭小棒的过程及横式和竖式：13÷4=3（个）……1（根）答：可以搭3个正方形，还剩1根。引导学生认识竖式中：“13”表示把13根小棒拿去分，“4”表示摆一个正方形需要4根小棒，“3”表示可以摆3个正方形（强调单位“个”），“12”表示3个正方形共12根（4×3=12）。“1”表示摆了3个后还剩下1根（强调单位：“根”），说明“1”是这个竖式的余数，这1根不能再继续往下分了。
北师大版小学数学二年级下册《分草莓》说课稿
二、说教学目标：1、探索有余数除法的试商方法，让学生再探索、练习中积累有余数除法的试商经验。2、运用有余数除法的有关知识，联系生活实际解决简单的问题，体验成功的喜悦。三、说教学重难点：1、让学生经历试商的过程，积累试商的经验，逐步达到熟练程度。2、使学生理解和掌握有余数除法的试商方法。体会余数要比除数小。四、说教学方法：探究、自主合作交流。五、说教具：课件、六、说教学过程：由于二年级学生，他们活泼好动，争强好胜，想象丰富，求知欲旺盛；学习责任感不断增强，但学习往往从兴趣出发；他们注意力不稳定、不持久，无意注意占主导地位，缺乏独立思考能力，容易受外界事物的干扰。因此，教学中培养学生参与数学活动的兴趣，培养良好的学习习惯，帮助他们逐步树立自信、自尊、自律等积极心态，是他们通过思考，提高自我认知能力，自我控制能力，这是提高课堂教学效益的基础，也是教师需努力和强化之处。下面我将详细说说我的教学过程：
北师大版小学数学二年级下册《买电器》说课稿
一、说教学内容及目标。《买电器》是北师大版二年级数学下册第六单元“加与减（一）”的一课时。本科教材通过创设学生熟悉的买电器的生活情境，请学生提出相关的数学问题，学习整百、整十数相加减的口算。本节课是在学生掌握了100以内加减法及万以内数的认识的基础上进行的，学好本节课为今后进一步学习整数加减法打下了坚实的基础。对学生来说，对各种电器非常熟悉，并且有逛家电商场的经历，能根据情境提出相应的加减法问题。孩子们能正确迅速地口算20以内的加减法，部分学生能口算整百、整十数的加减法，但对于算理的理解比较欠缺。为此我确定以下教学目标及重难点。教学目标：1、引导学生探索并掌握整十数、整百的加减计算方法，经历与他人交流计算方法的过程，并能正确计算。2、结合具体情境，提出用整十数、整百数解决的问题，发展提出问题和解决问题的意识和能力。
北师大版小学数学二年级下册《认识角》说课稿
二、学情分析对于学生来说，在认识角之前，已经具备了有关角的感性经验。但是，低年级学生的认知规律是以具体的形象思维为主，抽象思维能力较低。这部分内容对于二年级学生来说比较抽象，接受起来较为困难。为了帮助学生更好的认识角，形成角的表象。我设计了一些贴近学生生活的数学活动，让孩子在实践活动中经过独立思考，合作探究去认识角，发现角，从而感受到生活中处处有角。三、教学目标及重难点依据《课标》的要求和教材的特点，结合学生的生活实际及年龄特征，我确定了如下的教学目标：1、结合生活情境，感受生活中处处有角，体会数学与生活的密切联系。2、通过摸一摸、找一找、搭一搭、画一画、比一比等活动让学生直观地认识角，感受角的大小。
北师大版小学数学二年级下册《比一比》说课稿
解决了以上三个问题以后，我再让学生先独立将四座山的高度按照从小到大的顺序排列出来，这时，我会适当地引导学生阅读前面三个问题的解决过程，并梳理进行多位数比较的思路：先按数位比，再从高位看起。（三）分层次练习，巩固新知识在学生掌握了上述比较大数的方法以后,我将让学生运用所学的新知识,去解决”练一练”中的第1,2,5题。其中第1，2题是为了巩固“万以内的数的比较方法”，“能用符号表示万以内数的大小”这两个知识点；而第五题则是为了鼓励学生在新的情景中，进行数的大小比较。（四）课程总结这节课，同学们收获了什么？学生一定会很轻易地将上面四座山进行比较的规律说出来的。这时,我会引导学生回顾全文第四,板书设计(略)本节课，我将用最简单的文字体现重难点，便于学生理解。我的说课到此结束，谢谢大家！
