3、开始游戏。学生总是输，产生认知冲突，从而引起进一步探索的欲望。（二）小组内游戏，探索结论。通过小组内游戏的方式，进行实验，利用统计的方式呈现实验的结果，初步探索教师总能赢的原因。要引导学生在实验的结果中寻找统计学上的规律。（三）理论验证通过组合的理论来验证实验的结果。可以用不同的方式来进行组合，让学生探讨每个“和”所包含的组合情况的多少与这个“和”出现的次数之间的关系。三、师生共同小结本次活动1、通过本次活动，你有什么新的收获？2、师生总结：本次活动通过猜想、实验、验证等过程，让同学们在问题情境中自主探索，解决问题，既发展了同学们的动手实践能力，又充分调动了同学们的学习兴趣。
人教版新课标小学数学六年级上册一个数除以分数说课稿2篇
教学难点：理解整数除以分数的计算方法；二、说教法和学法为了突出重点，分散难点，让学生积极主动地参与到知识形成的过程中来。教学中采用分步探究，分步实施的原则。把整数除以分数的计算方法分两步进行探究。1.整数除以几分之一的计算方法；2.整数除以几分之几的计算方法；这样做，可以使学生通过自己的努力，小组合作交流，发现整数除以分数的计算方法。数学教学不仅是让学生获得数学的基础知识，还要教给学生学习知识的方法。培养学生的能力，发展学生的智力。教学中，让学生观察，分析，讨论引导学生寻找方法。再通过发现总结运用法则巩固知识内容。通过调动学生的积极性，不仅使学生学会了，而且会学了，会用了。从而也形成了一套良好学习方法，增强能力发展智力。

新人教版高中英语必修3Unit 5 The Value of Money-Reading and Thinking教学设计一
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

人教版新课标高中地理必修2第一章第三节人口合理容量教案
生：环境承载力是指环境能持续供养的人口数量。师：对了。但是有同学仍然会感到这是一个很抽象的概念。下面我们具体来了解什么是环境承载力。我们可以从两个部分去理解：一、环境，它主要是指环境的单个要素（如：土地、水、气候、植被等。）及其组合方式。二、是承载力，它指在特定的条件下，具体某事物能承受的某种活动的最大值。那环境承载力的科学定义是怎样表达的呢？生：环境承载力是指某一时期，某种状态条件下，某地区环境所能承受的人类活动作用的阈值。师：很对。 我们可以用一个生动的例子来说明。一只木桶里面的水的多少在底面积固定不变的情况下是由哪块木板来决定？生：最短的那块。师：确实如此。这就是我们平常所讲的 “木桶效应”。那影响环境承载力的大小也是由环境个要素里面最紧缺的那个要素来决定的。下面我们用一个例子来印证一下。
