5、課本練習(xí)：P129引導(dǎo)學(xué)生運(yùn)用隨機(jī)數(shù)表來模擬試驗(yàn)過程并給予解答。問題2：有四個(gè)鬮，其中兩個(gè)分別代表兩件獎(jiǎng)品，四個(gè)人按順序依次抓鬮來決定這兩件獎(jiǎng)品的歸屬，先抓的人中獎(jiǎng)率一定大嗎？教法：可組織學(xué)生用試驗(yàn)的方法來說明問題，對(duì)于試驗(yàn)的結(jié)果是有說服力的，很容易使學(xué)生相信摸獎(jiǎng)的次序?qū)χ歇?jiǎng)的概率沒有影響。問題3：彩民甲研究了近幾期這種體育彩票的中獎(jiǎng)號(hào)碼，發(fā)現(xiàn)數(shù)字06和08出現(xiàn)的次數(shù)最多，他認(rèn)為，06和08是“幸運(yùn)號(hào)碼”，因此，他在所買的每一注彩票中都選上了06和08。你認(rèn)為他這樣做有道理嗎？教法說明：要讓學(xué)生看到試驗(yàn)方法對(duì)試驗(yàn)結(jié)果的影響：1、 因?yàn)殚_獎(jiǎng)用的36個(gè)球是均勻的、無差別的，所以每個(gè)號(hào)碼被選為中獎(jiǎng)號(hào)碼的可能性是一樣的，不存在“幸運(yùn)號(hào)碼”。

Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.
人教版高中英語必修4A taste of English Humor說課稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

一、人類遺傳病1．概念2．分類(1)單基因遺傳病(2)多基因遺傳病(3)染色體異常遺傳?、僭颌陬愋?遺傳病的特點(diǎn)4．遺傳病對(duì)人類的危害八、說布置作業(yè)在作業(yè)的布置中，我嚴(yán)格遵循“重質(zhì)量、輕負(fù)擔(dān)”的指導(dǎo)思想。第一題主要是為了幫助學(xué)生及時(shí)糾正原有的對(duì)知識(shí)的錯(cuò)誤理解或片面認(rèn)識(shí)，培養(yǎng)學(xué)生的解題技巧和技能。所以我選用了該題。同時(shí)想借助該題培養(yǎng)學(xué)生對(duì)問題的科學(xué)的思維方法和探究的精神。幫助學(xué)生提高對(duì)信息技術(shù)運(yùn)用的熟練程度，發(fā)展學(xué)生的信息素養(yǎng)。附作業(yè)：1、連線題，請(qǐng)同學(xué)們連線指出下列遺傳各屬于何種類型？（1）苯丙酮尿病 A、單基因遺傳病（2）21三體綜合征（3）抗維生素D佝僂病 B、多基因遺傳?。?）軟骨發(fā)育不全（5）青少年型糖尿病 C、常染色體病2、以生物小組為單位進(jìn)行人類遺傳病的調(diào)查。
人教版高中生物必修1細(xì)胞中的無機(jī)物說課稿
為了加強(qiáng)學(xué)生的理解，讓學(xué)生討論以下問題。由師生共同總結(jié)。播放一個(gè)短時(shí)視頻，讓學(xué)生認(rèn)識(shí)到水的重要性后，展示節(jié)水標(biāo)識(shí)，說明由來。細(xì)胞中的無機(jī)鹽這部分，我將展示圖表，并列出問題：表中哪些成分屬于無機(jī)鹽？為什么要在運(yùn)動(dòng)員喝的飲料中添加無機(jī)鹽？無機(jī)鹽在細(xì)胞的生活中起什么作用？然后展示廣告語，讓學(xué)生思考和討論以下問題，并得到答案。再閱讀課本，驗(yàn)證自己的答案是否正確。關(guān)于無機(jī)鹽的作用較難理解，通過列舉人體生活與健康中的各種實(shí)例來加深感性認(rèn)識(shí)，加強(qiáng)對(duì)理論知識(shí)的理解3、課堂小結(jié)，強(qiáng)化認(rèn)識(shí)。（3—5分鐘）課堂小結(jié)，可以把課堂傳授的知識(shí)盡快地轉(zhuǎn)化為學(xué)生的素質(zhì)；簡(jiǎn)單扼要的課堂小結(jié)，可使學(xué)生更深刻地理解理論知識(shí)在實(shí)際生活中的應(yīng)用，并且逐漸地培養(yǎng)學(xué)生具有良好的個(gè)性。4、板書設(shè)計(jì)我比較注重直觀、系統(tǒng)的板書設(shè)計(jì)，還及時(shí)地體現(xiàn)教材中的知識(shí)點(diǎn)，以便于學(xué)生能夠理解掌握。5、布置作業(yè)。
