好玩的磁铁教案教学设计
中班的幼儿开始愿意探究新异的事物或现象来满足自己的好奇心，所以，我们的科学活动设计要在浅显易懂，适合中班幼儿年龄特征的同时，引发幼儿对科学的初步探究能力。中班的幼儿已经具有注意到新异事物或现象的，因此，我们在设计科学活动时要让幼儿充分发挥想象，对磁铁这种“新异”事物提出问题，如什么是磁铁？什么时候看见过磁铁？等等类似的问题，可以增强幼儿的探索兴趣，提高幼儿的探索的积极性，有利于激发幼儿的想象力。 中班幼儿主要以具体形象为主，需要具体的活动场景和活动形式，所以活动设计要提供幼儿合适的情景以提供操作思考的机会，进一步发展幼儿的自主性和主动性。中班幼儿与小班幼儿相比，活动时间也有所增加，因此也需要在活动时间上给予一定的保证。
图形的全等教案教学设计
教法分析：在新课程的教学中教师要向学生提供从事数学活动的机会,倡导让学生亲身经历数学知识的形成与应用过程，鼓励学生自主探索与合作交流，让学生在实践中体验、学习。因此，本节课我采用了多媒体辅助教学与学生动手操作、观察、讨论的方式，一方面能够直观、生动地反映各种图形的特征，增加课堂的容量，吸引学生注意力，激发学生的学习兴趣；另一方面也有利于突出重点、突破难点，更好地提高课堂效率。学法分析：初二年级学习对新事物比较敏感，通过新课程教学的实施，学生已具有一定探索学习与合作交流的习惯。但是一下子要学生从直观的图形去概括出抽象图形全等的概念这是比较困难的。因此，我指导学生：一要善于观察发现；二要勇于探索、动手实验；三要把自己的所思所想大胆地进行交流，从而得出正确的结论，并掌握知识。

3）乘除运算①有理数的乘法法则：（老师给出，学生一起朗读）1. 两数相乘，同号得正，异号得负，并把绝对值相乘；2. 任何数与零相乘都得零；3. 几个不等于零的数相乘，积的符号由负因数的个数决定，当负因数有奇数个数，积为负；当负因数的个数为偶数个时，积为正；4. 几个有理数相乘，若其中有一个为零，积就为零。②有理数的除法法则：（老师提问，学生回答）1. 两个有理数相除，同号得正，异号得负，并把绝对值相除；2. 除以一个数等于乘以这个数的倒数。③关系（老师给出）除法转化为乘法进行运算。
反比例函数教案教学设计
本节的内容主要是反比例函数的概念教学.反比例函数概念的建立，不能从形式上进行简单的抽象与概括，而是对这些实例从不同角度抽象出本质属性后，再进行概括。教材设计的基本思路是从现实生活中大量的反比例关系中抽象出反比例函数概念，让学生进一步感受函数是反映现实世界中变量关系的一种有效数学模型，逐步从对具体反比例函数的感性认识上升到对抽象的反比例函数概念的理性认识. 同时本节的学习内容，直接关系到本章后续内容的学习，也是继续学习其它各类函数的基础，其中蕴涵的类比、归纳、对应和函数的数学思想方法，对学生今后研究问题、解决问题以及终身的发展都是非常有益的.基于以上分析，本节教学设计是建立在一个个数学活动的基础上，经过对情境理解、本质抽象的积累而形成的.让学生对一类问题情境中两个变量间的关系，在充分经历写表达式，计算函数值和观察函数值随自变量变化规律的过程中，逐步概括形成反比例函数的概念.针对教学实际，我选取了贴学生现实的，有价值的实例“文具店里买学习用品”和“剪面积为定值的长方形纸片”等作为问题情境.

新人教版高中英语选修2Unit 2 Bridging Cultures-Discovering useful structures教学设计
The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3. Inspire the students to systematize the function and usage of noun clause1.Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.2.Inspire the students to systematize the function and usage of noun clauseStep1: The teacher ask studetns to find out more nominal clauses from the reading passage and udnerline the nominal clauses.

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分，只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition

In the early 19th century, _2_________ an outbreak of cholera hit Europe, millions of people died. But neither its cause, 3__________ its cure was understood. A British doctor, John Snow, wanted to solve the problem and he knew that cholera would not be controlled _4_________ its cause was found. In general, there were two contradictory theories 5 __________ explained how cholera spread. The first suggested that bad air caused the disease. The second was that cholera was caused by an _6_________(infect) from germs in food or water. John Snow thought that the second theory was correct but he needed proof. So when another outbreak of cholera hit London in 1854, he began to investigate. Later, with all the evidence he _7_________ (gather), John Snow was able to announce that the pump water carried cholera germs. Therefore, he had the handle of the pump _8_________ (remove) so that it couldn't be used. Through his intervention，the disease was stopped in its tracks. What is more, John Snow found that some companies sold water from the River Thames that __9__________________ (pollute) by raw waste.

Step 5： After learning the text, discuss with your peers about the following questions:1.John Snow believed Idea 2 was right. How did he finally prove it?2. Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.keys:1. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century.

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!
