二、教学设计的理念与思路。 阅读是个性化的过程，不能以教师的思维而取代学生思维，所以，我在引导学生阅读的时候，强调以学生为主体，让他们自读自悟，说一说感兴趣的景色，抄一抄优美的句子。关注他们情感的生成、个性的体验和生活的联系。 阅读不仅仅是人文性教育，更不可忽视的是语文基本技能的训练，课标提出这一学段的学生能"用普通话正确、流利、有感情地朗读课文"、"理解词句的意思"、"积累课文中的优美词句、精彩语段"等要求。所以我引导学生在解读课文的过程中，同时进行词语的运用，朗读的训练，写法的提炼，使人文性与工具性融为一体。 三、教学过程的安排及意图。 根据课文任务量，我将用两节课完成教学。第一节课的任务是通读课文及精读课文第1~4自然段。第二节课的任务是品读5~7自然段及识字。下面我说说第一节课的安排与意图。

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

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!

小学数学人教版四年级下册《观察物体（二）》说课稿
一．我对教材的理解（教材地位作用分析）——参考教学参考书《观察物体（二）》是物体的空间位置关系与形状的认识，是小数教学中的重要基础内容之一，也是小学生学习图形与几何数学知识需要掌握的基础知识和基本技能。本课内容是学生在学习了从不同角度（视角）观察物体位置与形状的基础上学习的。教材选取学生熟悉的空间环境和物体，通过从相同的角度（视角）位置观察、认识不同几何组合体形状的活动，认识、感悟从相同角度（视角）观察不同物体，看到的形状可能相同也可能不同，丰富、发展学生空间观念和观察、思考、判断能力，为进一步学习图形与几何知识铺路奠基。二．学情分析（根据考评要求，可不说）因为年龄特征决定了四年级学生活泼好奇好动，虽具一定的抽象思维能力，但仍然以形象思维为主；通过前面从不同方向角度观察认识简单物体的形状的学习，具一定的初步观察思考判断能力和左、右、前、后的二维空间观念，但却十分稚嫩；同时又存在个体差异，多数学生思维活跃，数学兴趣浓厚，表现欲望强烈，少数学生缺乏积极性，学习被动，基础较为薄弱；部分学生新知基础遗忘。

2.某小组有20名射手，其中1，2，3，4级射手分别为2，6，9，3名.又若选1，2，3，4级射手参加比赛，则在比赛中射中目标的概率分别为0.85，0.64，0.45，0.32，今随机选一人参加比赛，则该小组比赛中射中目标的概率为________. 【解析】设B表示“该小组比赛中射中目标”，Ai(i=1，2，3，4)表示“选i级射手参加比赛”，则P(B)= P(Ai)P(B|Ai)= 2/20×0.85+ 6/20 ×0.64+ 9/20×0.45+ 3/20×0.32=0.527 5.答案：0.527 53.两批相同的产品各有12件和10件，每批产品中各有1件废品，现在先从第1批产品中任取1件放入第2批中，然后从第2批中任取1件，则取到废品的概率为________. 【解析】设A表示“取到废品”，B表示“从第1批中取到废品”，有P(B)= 112，P(A|B)= 2/11 ，P(A| )= 1/11所以P(A)=P(B)P(A|B)+P( )P(A| )4．有一批同一型号的产品，已知其中由一厂生产的占 30%, 二厂生产的占 50% , 三厂生产的占 20%, 又知这三个厂的产品次品率分别为2% , 1%, 1%，问从这批产品中任取一件是次品的概率是多少？
人教版高中数学选修3条件概率教学设计
(2)方法一:第一次取到一件不合格品,还剩下99件产品,其中有4件不合格品,95件合格品,于是第二次又取到不合格品的概率为4/99,由于这是一个条件概率,所以P(B|A)=4/99.方法二:根据条件概率的定义,先求出事件A,B同时发生的概率P(AB)=(C_5^2)/(C_100^2 )=1/495,所以P(B|A)=(P"(" AB")" )/(P"(" A")" )=(1/495)/(5/100)=4/99.6.在某次考试中,要从20道题中随机地抽出6道题,若考生至少答对其中的4道题即可通过;若至少答对其中5道题就获得优秀.已知某考生能答对其中10道题,并且知道他在这次考试中已经通过,求他获得优秀成绩的概率.解:设事件A为“该考生6道题全答对”,事件B为“该考生答对了其中5道题而另一道答错”,事件C为“该考生答对了其中4道题而另2道题答错”,事件D为“该考生在这次考试中通过”,事件E为“该考生在这次考试中获得优秀”,则A,B,C两两互斥,且D=A∪B∪C,E=A∪B,由古典概型的概率公式及加法公式可知P(D)=P(A∪B∪C)=P(A)+P(B)+P(C)=(C_10^6)/(C_20^6 )+(C_10^5 C_10^1)/(C_20^6 )+(C_10^4 C_10^2)/(C_20^6 )=(12" " 180)/(C_20^6 ),P(E|D)=P(A∪B|D)=P(A|D)+P(B|D)=(P"(" A")" )/(P"(" D")" )+(P"(" B")" )/(P"(" D")" )=(210/(C_20^6 ))/((12" " 180)/(C_20^6 ))+((2" " 520)/(C_20^6 ))/((12" " 180)/(C_20^6 ))=13/58,即所求概率为13/58.

小学数学人教版六年级上册《百分数整理与复习》说课稿
一、说教材《百分数》是九年义务教育课程标准试验教科书人教版小学数学五年级下册第六单元的教学内容。百分数是在学过整数、小数，特别是分数的意义和应用的基础上进行教学的。本单元教材在编写上体现从实际情境中抽象出百分数的过程。让学生体会引入百分数的必要性和百分数的意义，感受百分数在实际生活中的应用。二、说学情学生已经认识了百分数，并掌握了百分数的简单计算和应用。生活中存在着较多的百分数，学生在生活中或有所见、或有所闻。如衣服上 80％棉、牛奶纯度 100％等等。这些为本节课的开展奠定了生活经验基础。
小学数学人教版三年级下册《两位数乘两位数》整理与复习 说课稿
单分析。一、说教材的地位和作用本节课的内容是人教版小学数学三年级下册第五单元的内容。在此之前，学生已经学习了两位数乘一位数笔算和两位数乘整十数的口算，估算和笔算。本节课学习的内容就是对以上知识点的梳理与巩固复习。二、说教学目标根据本教材的结构和内容分析，结合三年级学生的认知结构及其心理特征，我制定了以下的教学目标：1、通过复习，把“两位数乘两位数”这一单元的有关知识系统化、条理化。2、通过自主探索与合作学习，在系统复习的基础上理清知识脉络并进行分析归纳，掌握有序整理的方法，提高学习能力。3、经历独立整理、相互交流、综合应用的过程，感受学习的快乐。 三、说教学的重、难点本着《小学数学新课程标准》，在吃透教材基础上，我确定了以下的教学重点和难点。教学重点：用两位数乘两位数解决问题。 教学难点：笔算乘法积的定位。为了讲清教材的重、难点，使学生能够达到本节课设定的教学目标，我再从教法和学法上谈谈。
小学数学人教版三年级下册《除数是一位数的除法》整理和复习说课稿
一、说教材我说课的内容是人教版小学数学三年级下册中的“除数是一位数的除法单元的整理与复习”。这个单元的教学是在学生掌握了整十、整百的数除以一位数的口算、除法的估算和笔算以及验算的基础上进行的，它是以后学习较复杂除法的基础。本节课的教学重点是通过整理与复习，学生进一步理解除法的算理，掌握算法，提高计算能力，教学难点是在整理与复习中形成知识网络，在学习中学会整理与复习的方法。众所周知，整理和复习是为教学中的单元复习、单元知识小结而设计和编排的，以帮助学生达到“再现、整理、巩固已学知识，并使之系统化”的目的。根据复习课型的这一特点和学生的实际情况，我把教学目标分为三个方面：（1）知识性目标：通过复习使学生把“除数是一位数的除法”这一单元的有关计算知识系统化，条理化。（2）能力目标：使学生学会在系统复习的基础上理清知识的脉络，进行分类归纳、有序整理的学习方法，提高学习能力。（3）情感目标：通过自主探索与合作学习，培养学生的创新意识和团队精神，渗透生活中处处有数学的观念，并通过学生解决实际问题，感受数学与实际生活的密切联系。
