三、孟德爾遺傳規(guī)律的現(xiàn)代解釋①分離定律:在雜合體的細胞中,位于一對同源染色體上的等位基因,具有一定的獨立性;在減數(shù)分裂形成配子的過程中,等位基因隨同源染色體的分開而分離,獨立地隨配子遺傳給后代。②自由組合定律:位于非同源染色體上的非等位基因的分離或組合是互不干擾的;在減數(shù)分裂過程中,同源染色體的等位基因彼此分離的同時,非同源染色體上的非等位基因自由組合??偨Y(jié):再次強調(diào)孟德爾遺傳定律的現(xiàn)代解釋課堂練習:書本31頁6、教學反思:本節(jié)課設置了一系列問題情境,層層設問,在學生答問、質(zhì)疑、討論過程中讓學生建構新概念和新的知識體系,并通過教師及時掌握反饋信息,適時點撥、調(diào)節(jié),讓學生在推理判斷中培養(yǎng)良好的思維習慣和對知識的遷移能力,而且通過留出一定的時間讓學生提問,體現(xiàn)了以學生為主體的思想。

四、說教學程序(一).溫故知新、導入新課復習提問:基因突變導致生物變異的原因是什么?回答:基因突變是基因結(jié)構發(fā)生改變,從而使遺傳信息改變,使蛋白質(zhì)結(jié)構改變、生物性狀改變,即生物發(fā)生了變異。那么,基因是什么?它和染色體又有何關系?回答:基因是有遺傳效應的DNA片斷,染色體是DNA的載體,基因在染色體上呈線形排列。引出新知:對于一個生物體來說,正常情況下,其染色體的結(jié)構和數(shù)量都是穩(wěn)定的。但在自然條件或人為因素的影響下,染色體的結(jié)構和數(shù)量均會發(fā)生改變,從而導致生物性狀的改變,這就屬于染色體變異。(二).把握重點、突破難點重點的把握:1、染色體結(jié)構的變異播放影片:貓叫綜合征幼兒。讓學生觀察: 患兒哭聲輕、音調(diào)高,很像貓叫。教師補充: 患兒的征狀---兩眼較低、耳位低下,存在著嚴重的智力障礙。闡述病因---染色體片段缺失

一. 教材分析1. 本單元的中心話題是“計算機(Computers)”,內(nèi)容涉及計算機的發(fā)展歷史,計算機的應用等。本節(jié)課是該單元的第一課時,我將Warming up, Pre-reading and Comprehending這四部分整合為一節(jié)精讀課。其中。Reading部分是題為WHO AM I?的文章,以第一人稱的擬人手法介紹了計算機發(fā)長演變的歷史和計算機在各個領域的應用,其主旨是表達計算機的發(fā)展變化之快以及在生活中用途之廣。而Warming up部分以圖片的形式展現(xiàn)了計算機的發(fā)展歷程;Pre-reading中的問題和排序分別是為了預測語篇的內(nèi)容和測試學生對計算機歷史了解的情況;Comprehending則通過各項練習訓練學生的閱讀技能,從而加深對文章的理解。可見這幾部分是一個有機的整體。2. 教學目標:1) 語言目標:重點詞匯及短語:abacus, calculate, calculator, PC, laptop, PDA, robot, analytical, technological, universal, mathematical, artificial, intelligent, network, explore, in common, as a result.重點句子:a. My real father was Alan Turing, who in 1963 wrote a book to describe how computers could be made to work, and build a “universal machine” to solve any mathematical problem.

Ⅲ. Analysis of the teaching material:The topic of this unit is cultural relics. Students are quite interested in topics about different cultures around the world. This is the second period of the whole unit. As a reading class, the passage mainly talks about the history of the amber room (how it was made, sent as a gift, lost and rebuilt).According to the new national curriculum, when teaching reading, much emphasis should be put on training the students’ reading skills.Ⅳ. Teaching objectives1. Language objectives:1) Students are required to master the key words and phrases occurred in the passage (e.g. amazing, decorate, belong, in return, less than etc.)2) Students are required to learn the attributive clause and acquire the sentence pattern.2. 1) Students are required to describe a certain thing by using the new sentence patterns.2) Students are required to master two kinds of reading skills—skimming and scanning, and learn to use them in their daily reading.3. 1) Students are required to know the history of the amber room.2) Students are required to appreciate cultural relics and understand the importance of protecting them.Ⅴ. Teaching important and difficult points1) the new words, phrases, and sentence pattern in the course of reading.2) Teaching difficult point: Help the students master two kinds of reading skills—skimmingand scanning and learn to apply them in daily use.Ⅵ. Teaching methods:Task-based method & Top-down model Ⅶ. Teaching aids: PPT, pictures, blackboard Ⅷ. Teaching procedure:

Purpose of my design:To ask the students to do these two tasks will make the Ss predict the story of this passage. As a result, it will deepen Ss’ memory of this story because they will have their own understanding of this story.Step 3. While-readingTask 1. (Individual work _____min)Skimming: ask students to skim the text and the main ideas of each paragraph in this passage. Please read it quickly and then match the sentences with the letters.Task 2. (Individual work _____min)Scanning: read the text quickly and decide the whether the following statements are true or false and give reasons.Task 3. (Pair work _____min)Listen to the tape and fill in the banks. Then read the paragraph with expression to your partner.Task4 (individual work min)Listen to the tape again and write down the main idea in one sentence.Purpose of my design: Enable students to understand the given material better by using different reading skills. And proper competition can arouse the Ss’ interest in English learning. “Task-based” teaching method is used here todevelop the Ss’ ability of communication and also their ability of co-operation will be well trainedStep 4. Post-readingTask 1. (Individual work, pair work, group work, class work; _____min)Discussion (group of 4):1. If you were Hippomenes, would you run against Atlanta?2. Do you think Hippomenes deserved to win the race? Why or why not?Step 5. HomeworkPlease read the story again carefully after class and imagine: What will happen during the race between Hippomenes and Atlanta? Who do you think will win the race? Do you think Atlanta would marry Hippomenes? Write an end for the story with thses questions.Purpose of my design: Homework is so important and necessary for to master the knowledge they learned after class. It will check whether the Ss achieve the teaching aims.Part 5 Blackboard design

Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.

When it comes to the students’ studying methods, I'd like to introduce my Ss first. The Ss have a good command of basic language points. They’re interested in learning English, and they take an active part in English class, so they will have fun in autonomous, cooperative and inquiry learning. I will just serve as a guide, showing them the way to explore how to make more progress in their English learning.Now it’s time for the most important stage of this lesson. My teaching procedures are arranged as follows:Step1.Leading-in (3 minute)Play a video of a wide variety of wildlife to introduce my topic. Step2. Speaking (12 minutes)We will use our textbook Page25. Let the Ss fast read the short paragraph to warm up. Ask them to talk about the report on some endangered wildlife in China with the dialogue patterns on the screen. Lastly, I will invite some groups to demonstrate their dialogues about saving wildlife in China.Step3.English play (3 minutes)Watch another video in praise of their excellent performance just now. It’s about Jack Chen’s(成龍)and Yang Ziqiong’s wildlife protection.Step4. Listening (twice 13 minutes)This time, I’ll ask the Ss to fill in the blanks of the monologue of the 2 movie stars above. Step5.Discussion (3 minutes)Which would you like to choose to wear, clothes made of cotton, artificial leather or animal skins? Why ?Step6. Summary (3 minutes)1. If there were no wildlife, there wouldn’t exist human beings. If the buying stops, the killing can, too.2. Animals are our friends. To love animals is to love ourselves. Stop hunting, killing and destroying wildlife.3. Let’s live in harmony with all the living things in the world. Step7. Music appreciation (3 minutes)Let the Ss appreciate the song Earth Song by Michael Jackson. Last but not the least, I will show you my blackboard design.

Teaching plan for Unit 1 book3Good morning, teachers. It’s my great pleasure to be here because I can share my lesson with you and I can learn a lot from it. I’ll begin my lesson from the following four parts, the teaching material, the teaching methods, the studying methods and the teaching procedure.Firstly, let me talk about the teaching material. The content of my lesson is the reading passage festivals and celebrations of Unit 1 Festivals around the world. This passage is about festivals and celebrations. By studying this passage, we’ll enable the students to know that festivals exit everywhere, and many of festivals in different countries celebrate similar ideas. As we all know, the reading passage is the center of each unit.

Computer assisted language teaching.3. question-and–answer methodThirdly, Studying Methods:

在接下來的細讀環(huán)節(jié),我套用了高考對閱讀理解的考查方式設置了5個問題,分別為三個推理判斷題,一個細節(jié)題和一個主旨大意題。學生需要對文章的內(nèi)容進行分析、歸納、推理、猜測等高級思維活動才能做出正確的回答?!驹O計意圖】這一過程是對學生進行細讀的訓練,培養(yǎng)學生獲取特定信息和挖掘文章深層次信息的能力。第三環(huán)節(jié):Intensive-reading (精讀) 15′第三個環(huán)節(jié)精讀,既是最重要的環(huán)節(jié),也是突破本課重難點的關鍵。首先,讓學生思考劇本中人物看到百萬英鎊前后的態(tài)度發(fā)生了怎樣的變化。其次,讓學生仔細閱讀文章,找出可以表現(xiàn)人物態(tài)度變化的具體的語言和動作。最后,讓學生總結(jié)人物的態(tài)度發(fā)生變化的根本原因是什么,從而引出Money Talks, 供學生思考?!驹O計意圖】通過一系列的活動培養(yǎng)學生學習從人物的語言和動作探究人物的心理,使學生進一步體會戲劇語言的魅力,從而對文章背后所反映的社會問題進行思考,也為下一步的討論環(huán)節(jié)做好鋪墊。

In this class, I have 3 teaching aims, that is, knowledge aims, ability aims and emotion aims.1) Knowledge-Teach students new words and expressions, such as temporary, bleed,sprain choke, first aid, fall ill and so on.-Enable students to have a better understanding for some basic knowledge of first aid.2) Ability-Train students’ speaking, reading and writing abilities by different teaching activities, such as skimming, comprehending, team work, role play, retelling and writing.-Develop students’ reading strategy on how to move general idea to specific information.3) Emotion-Promote students’ awareness of giving first aid.- Cultivate students’ creativities.Then let’s come to my teaching methods and activities.III. Teaching methods and activities:To achieve different teaching aims, various kinds of teaching methods and activities will be adopted throughout this period, such as TBL (task-based learning), skimming, team work, brainstorm and others, which can offer students opportunities to fulfill tasks in which they can use language to achieve a specific outcome.IV. Teaching aids:Computer and blackboardV. Teaching important points:1) Make students have a clear mind for the structure of the text.2) Help students understand the theme of the text.VI. Teaching difficulties:1) So many new words may affect students’ understanding.2) How to get students to know about the functions of the skin and thecauses, characteristics and treatments for different degree burns,and the knowledge about giving first aid. VII. Blackboard design:

Good afternoon, everyone. It’s my great pleasure to be here sharing my lesson with you. The content of my lesson is Senior English for China Book5 Unit 3 Life in the Future. I’ll be ready to begin this lesson from six parts: Analysis of the teaching material, Analysis of the students, Teaching aims and important and difficult points, Teaching methods and aids, Teaching procedures, and Blackboard design. First, let me talk about the teaching material.Part 1 Analysis of the Teaching Material:This unit is about what human beings’ life will be like in about one thousand years. By studying of this unit, we’ll Enable the students to know the changes in humans’ life and some new inventions bringing about the change and develop the interest in science. This lesson plays an important part in the English teaching in this unit. This is an important lesson in Book Five. From this lesson, it starts asking the Ss to grasp contents of each passage. Therefore, this lesson is in the important position of the teaching material. If the Ss can learn it well, it will be helpful to make the Ss learn the rest of this unit.Part 2 Analysis of the SsAs Senior2 Ss, they are at different levels of English fluency, some of them have lost interest in English.

各小組派代表匯報。4、教師提出問題組織學生討論:⑴要想了解更多的綠色食品,了解綠色食品的銷售情況,我們應該怎么做?⑵要想了解廣大消費者對綠色食品的態(tài)度,食用綠色食品的意義,是否懂得辨認綠色食品,以及什么樣的人群對此知識最缺乏等,我們應該怎么做?組織學生匯報交流。5、做個“綠色食品”廣告設計師。為你喜歡的綠色食品設計廣告語,每組推薦一個。6、讓學生了解綠色食品認證程序。7、綠色食品打“假”隊員在行動。8、向?qū)W生介紹生態(tài)綠色食品基地。三、活動總結(jié):通過研究、探討,了解學生對綠色食品的態(tài)度。提問:民以食為天,吃,是一個大問題,如果你的爸爸媽媽讓你到超市買牛奶、方便面等,你會選擇什么樣的食品?為什么?希望通過今天的學習,同學們能夠做到綠色消費,也希望你們向自己的家人、向周圍的了解學生對“無公害食品”、“有機食品”與“綠色食品”的認識。

1.說教材《記念劉和珍君》是魯迅先生用飽醮著熱淚,用悲憤的筆調(diào)寫下的一篇感人至深的散文,既有對愛國青年沉痛的悼念,又有對反動派憤怒的控訴,也有對覺醒的國民的吶喊。《記念劉和珍君》是高中語文必修1第三單元第一課的講讀課文。文中描摹人物的音容笑貌,敘述人物的行為事跡,都融入了作者真摯的情感和深刻的感悟。對學生明辨是非,領悟時代精神和人生意義,有著重要的作用。新課標強調(diào)了要全面提升高中學生的語文素養(yǎng),初步形成正確的世界觀、人生觀、價值觀,并學會收集、判斷、處理信息,具有人文素養(yǎng)、創(chuàng)新精神與實踐能力。同時,《記念劉和珍君》感情真摯,感悟深刻,具有典型人文性。結(jié)合本單元教學目標,確立教學目標如下。

3、拓展延伸,啟迪心智,創(chuàng)設課堂訓練營。三、說學法1、紙上得來終覺淺,圈點、勾畫、批注法,學好文言基本功。2、自主合作加探究,眼耳口腦手并用,破疑解難在其中。四、說課時安排《鴻門宴》篇幅較長,文言知識較豐富,文章內(nèi)涵豐厚,因此我設計用五課時教學本文。第一課時:了解作家作品,積累文言知識,感受作者隱忍發(fā)憤的著書精神(初讀)第二課時:理清故事情節(jié),概括人物形象,學習客觀地評論歷史人物,(熟讀)第三課時:進一步梳理文言知識,精讀課文,要求讀透。(精讀)第四課時:通過對人物、事件的賞析,加深學生對人物的理解,鍛煉學生的開放性思維,由學生自主認識到人物的性格,悲劇的原因等問題。(賞讀)第五課時:補充課本教學內(nèi)容:同學生一起閱讀古今關于劉邦項羽的一些篇章:讓學生投入進來,把握自己眼中的項羽。(展讀)在文言文學習的過程中,采取五步學習法:初讀-熟讀-精讀-賞讀-展讀(板書)

一.教材理解教材地位與作用:本單元“閱讀與鑒賞”部分,本單元要求學生能在了解詩歌創(chuàng)作的時代背景的情況下通過反復誦讀詩歌,把握其中豐富的意象,領悟詩歌獨特的意境和詩人所要表達的情感。《雨巷》是現(xiàn)代派大師戴望舒的成名作和前期的代表作,他曾因此而贏得了“雨巷詩人”的雅號。本單元以《雨巷》為例子給學生展示了象征主義詩歌的特點,《雨巷》運用了象征性的抒情手法。詩中那狹窄陰沉的雨巷,在雨巷中徘徊的獨行者,以及那個像丁香一樣結(jié)著愁怨的姑娘,都是象征性的意象。這些意象又共同構成了一種象征性的意境,含蓄地暗示出作者即迷惘感傷又有期待的情懷,并給人一種朦朧而又幽深的美感。富于音樂性是《雨巷》的另一個突出的藝術特色。詩中運用了復沓、疊句、重唱等手法,造成了回環(huán)往復的旋律和宛轉(zhuǎn)悅耳的樂感。因此我把本課的教學重點和難點確定為:教學重點:通過反復誦讀,領略詩歌的音樂美以及分析其成因教學難點:分析意象以及其象征意義初步掌握鑒賞詩歌的方法

陸王心學與程朱理學相比有何異同?生 不同點:在理的內(nèi)涵上不同,程朱理學認為“理”是貫通于宇宙、人倫的客觀存在,是一種普遍的規(guī)律準則;陸王心學認為心即理,是“良知”,認為人心便是世界萬物的本原。方法上也有不同:前者向外追究,“格物致知”;后者向內(nèi)探求,“發(fā)明本心”以求理,克服私欲、回復良知。生 相同點:都提出了一個宇宙、社會、人生遵循的“理”。師 對。程朱理學是客觀唯心主義,陽明心學是主觀唯心主義。這兩者的分歧是理學范圍內(nèi)的分歧,其基本思想是一致的。師 宋明理學與漢唐以前的儒學比較,最大的特點在于批判地吸收了佛教哲學的思辨結(jié)構和道教的宇宙生成論,將儒家的倫理學說概括升華為哲學基本問題。其實質(zhì)是把佛、道“養(yǎng)性”“修身”引向儒家的“齊家”“治國”“平天下”,對儒家的綱常道德給予哲學論證,使之神圣化、絕對化、普遍化,以便深入人心,做到人人遵而行之。

In this step, give students a few minutes to read the passage . While they are reading, I will write some key words of the text on the blackboard. Then ask students to retell the passage according to the key words.By retelling, students can improve their ability of language organization and have an overall understanding of the article.Step 4 Group discussionIn this step, students will be divided into groups of 4 to discussion the following question: What qualities make a great person?After their discussion, invite a few groups to make a report to the class.This group discussion can practice students’ oral English and cultivate their abilities of cooperation and communication.Step 5. HomeworkLet students write a short passage to introduce a great person he or she admires.The homework can consolidate the knowledge the students have learned and cultivate their writing ability.

On the left, there will be some new words and expressions. In the middle of the blackboard, I will write some useful sentence structures so that the students can know clearly what they’ve learned and then try to master the knowledge.OK. That’s all for my presentation. Thank you for your attention.

分析過焦作市的地理概況和產(chǎn)業(yè)優(yōu)勢后,就需要針對由于資源枯竭所帶來的問題提出合理化的建議。既然是談經(jīng)濟轉(zhuǎn)型,就應該將話題的范圍明確在這一領域內(nèi)。通過材料3的相關內(nèi)容,我們了解到焦作市需要在產(chǎn)業(yè)結(jié)構調(diào)整、培育新的優(yōu)勢產(chǎn)業(yè)、增強綜合競爭力等三個整改方針上下功夫。因而引導學生針對優(yōu)勢與不足提出建議,以三個整改方針為基準,衡量建議的可行性是鍛煉學生解決此類問題的有效途徑。在此我將教會學生的是解決問題方法而非案例的內(nèi)容,正所謂“授之以魚,不如授之以漁”。接下來針對學生的建議和教材資料分析所羅列的10點整改思路,由學生自由發(fā)言提出看法,通過教師的指導和學生的討論,進而確定經(jīng)濟轉(zhuǎn)型建議的具體方案。最后注意將建議與產(chǎn)業(yè)優(yōu)勢相對照,看建議是否都是圍繞著產(chǎn)業(yè)優(yōu)勢而提出的,這樣做會加深學生的印象,通過建議和優(yōu)勢的對應關系,將不難找出此類問題的解題思路。
