教學(xué)目標(biāo):1、引導(dǎo)學(xué)生通過(guò)計(jì)算、比較、觀察、等實(shí)踐活動(dòng),使學(xué)生理解倒數(shù)的意義,掌握求倒數(shù)的方法,并能正確熟練的求出倒數(shù)。2、通過(guò)自主探究、合作交流的方式培養(yǎng)學(xué)生與人合作的能力。3、提高學(xué)生學(xué)習(xí)數(shù)學(xué)的興趣,發(fā)展學(xué)生質(zhì)疑的習(xí)慣。教學(xué)重點(diǎn):知道倒數(shù)的意義和會(huì)求一個(gè)數(shù)的倒數(shù)教學(xué)難點(diǎn):1、0的倒數(shù)的求法。二、說(shuō)教法基于教材內(nèi)容比較單調(diào),那么只有在教法上體現(xiàn)新、奇、特,才能讓學(xué)生想學(xué)、要學(xué)。在教學(xué)過(guò)程中,我將始終扮演一個(gè)組織者、引導(dǎo)者、合作者的角色,根據(jù)小學(xué)生從具體的形象思維逐步向抽象的邏輯思維發(fā)展的思維特點(diǎn),聯(lián)系小學(xué)生熟悉的身邊實(shí)際,使抽象的內(nèi)容直觀化,激發(fā)學(xué)生的學(xué)習(xí)興趣,引導(dǎo)學(xué)生去發(fā)現(xiàn)問(wèn)題、討論問(wèn)題,放手讓他們自主探究和合作交流,幫助他們?cè)谧灾魈骄?、合作交流中真正理解并掌握本?jié)課的數(shù)學(xué)知識(shí)、技能、思想和方法。
一、教材:《畫(huà)一畫(huà)》這一內(nèi)容是在學(xué)生學(xué)習(xí)了《變化的量》和《正比例》這兩節(jié)內(nèi)容以后安排的,學(xué)生已經(jīng)結(jié)合大量的生活情境認(rèn)識(shí)了生活中存在的許多相互依賴的變量,而且體會(huì)了這些變量之間的關(guān)系,認(rèn)識(shí)了正比例及其意義,能初步判斷兩個(gè)相關(guān)聯(lián)的兩是不是成正比例,感受了正比例在生活中的應(yīng)用,學(xué)生對(duì)正比例的認(rèn)識(shí)有了一定的基礎(chǔ)。教材安排這一內(nèi)容,一是讓學(xué)生進(jìn)一步認(rèn)識(shí)正比例,以及正比例中兩個(gè)相關(guān)聯(lián)的量之間的關(guān)系;二是通過(guò)讓學(xué)生在方格紙上描出成正比例的量所對(duì)應(yīng)的點(diǎn)并能在圖中根據(jù)一個(gè)變量的值估計(jì)它所對(duì)應(yīng)的變量的值,從而認(rèn)識(shí)正比例圖像的特點(diǎn)。主要意圖是引導(dǎo)學(xué)生運(yùn)用已有的知識(shí),用圖的形式去直觀表示兩個(gè)成正比例的量的變化關(guān)系,鼓勵(lì)學(xué)生發(fā)現(xiàn)當(dāng)兩個(gè)變量成正比例關(guān)系時(shí),所繪成的圖像是一條直線,在此基礎(chǔ)上,鼓勵(lì)學(xué)生利用圖,進(jìn)行一些估計(jì),解決一些問(wèn)題,為以后進(jìn)一步學(xué)習(xí)正比例函數(shù)打下一定的基礎(chǔ)。
2.放大空間,升華思考由于我對(duì)教材的二度開(kāi)發(fā)留給了學(xué)生足夠的探索空間,課上學(xué)生探索數(shù)學(xué)的熱情被充分調(diào)動(dòng),我們欣喜地看到:有的學(xué)生嘗試著不同平面圖形的旋轉(zhuǎn);有的學(xué)生只用一種平面圖形,卻旋轉(zhuǎn)出不同的立體圖形;有的學(xué)生的思維并沒(méi)有停留在表象上,而是在深入地思考產(chǎn)生這一現(xiàn)象的原因……交流時(shí)學(xué)生的發(fā)現(xiàn)遠(yuǎn)遠(yuǎn)超出了我們的想象,這份生成帶給我們的是驚喜,是贊嘆,更是“以操作促思考”的教學(xué)行為結(jié)出的碩果。3.巧用課件,形成表象本節(jié)課,我充分運(yùn)用現(xiàn)代信息技術(shù)將平面圖形經(jīng)過(guò)旋轉(zhuǎn)形成立體圖形的過(guò)程生動(dòng)、逼真地再現(xiàn)出來(lái),幫助學(xué)生將抽象的空間想象化為直觀,進(jìn)而形成表象,深植于學(xué)生的腦海中,促進(jìn)了學(xué)生空間觀念的形成。總之,在這節(jié)課上,我堅(jiān)持把“促進(jìn)學(xué)生發(fā)展”作為第一要素貫穿于課堂教學(xué)的始終,讓學(xué)生在充滿著民主、探究、思考的氛圍中,積極操作、主動(dòng)思考,發(fā)展了學(xué)生的空間觀念。
四、說(shuō)教法、學(xué)法我在教學(xué)中主要采用的教學(xué)方法是先學(xué)后教中的“兩學(xué)兩教”。輔之以多媒體教學(xué)手段(主要通過(guò)微課視頻的觀看學(xué)習(xí))。本課學(xué)生的學(xué)習(xí)方法主要有:自主發(fā)現(xiàn)法、合作交流法、自學(xué)嘗試法等。1.學(xué)生在自主探究解答例題,求兩種品牌罐頭的合格率時(shí),主要采用自學(xué)嘗試法,根據(jù)知識(shí)的遷移,學(xué)生能夠正確求出產(chǎn)品合格率。2.在總結(jié)小數(shù)、分?jǐn)?shù)化成百分?jǐn)?shù)的方法時(shí),學(xué)生主要采用自主發(fā)現(xiàn),合作交流的方法。首先讓學(xué)生觀察例題板書(shū),想一想怎樣把小數(shù)、分?jǐn)?shù)化成百分?jǐn)?shù),采用了“兵教兵”的方法,達(dá)到了人人參與的目的。當(dāng)然,由于學(xué)生所處的文化環(huán)境,家庭背景和自身思維方式的不同,不同的學(xué)生所采用的方法也不盡相同,作為教師要尊重學(xué)生的選擇,允許學(xué)生用自己喜歡的方式學(xué)習(xí)數(shù)學(xué)。五、說(shuō)教學(xué)過(guò)程
④聯(lián)系生活實(shí)際解決身邊的問(wèn)題,讓同學(xué)初步感受數(shù)學(xué)與日常生活的密切聯(lián)系,體驗(yàn)數(shù)學(xué)的應(yīng)用,促進(jìn)學(xué)生的發(fā)展。接下來(lái),我再具體談一談這堂課的教學(xué)過(guò)程。3、說(shuō)教學(xué)過(guò)程第一環(huán)節(jié):創(chuàng)設(shè)情境,激qing導(dǎo)入。同學(xué)們你們看屏幕上的是什么?(出示圖片)那么自行車車輪是什么形狀的?為什么車輪要設(shè)計(jì)成圓形?這里面有什么奧妙呢?學(xué)了今天的內(nèi)容大家就會(huì)明白的。這節(jié)課我們就走進(jìn)圓的世界去探尋其中的奧妙。板書(shū)課題:圓的認(rèn)識(shí)設(shè)計(jì)意圖:通過(guò)生活中實(shí)際例子引入課題,一方面引起學(xué)生的學(xué)習(xí)興趣,另一方面為學(xué)習(xí)新知識(shí)做了鋪墊,從思想上吸引了學(xué)生主動(dòng)參與學(xué)習(xí)的活動(dòng)。這一環(huán)節(jié)的設(shè)計(jì),主要是想體現(xiàn)數(shù)學(xué)就在我們的身邊,從而激發(fā)學(xué)生學(xué)習(xí)的興趣及學(xué)習(xí)的積極性。

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. Part 6 Blackboard Design(板書(shū)設(shè)計(jì))That’s all my teaching procedures. Finally, I’d like to say sth about part 6 blackboard design. On the top is the title. 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.
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 methods:Task-based method & Top-down model Ⅶ. Teaching aids: PPT, pictures, blackboard Ⅷ. Teaching procedure:
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.
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.
Language learning needs a context, which can help the learners to understand the language and then can product comprehensible output, so computer has the advantages to make the materials attractive.Part 3 Learning MethodsTask-based, self-dependent and cooperative learningPart 4 Teaching ProcedureStep One Lead-in“Interest is the best teacher.” Therefore, at the very beginning of the class, I should spark the students’ mind to focus on the centre topic “the band”. I’ll show some pictures of food to attract their attention and then bring some questions.Question:What kind of food they like?What should go into a good meal?The answers must relate to the diet. After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.
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:
今天我們來(lái)介紹一下必修五第四單元的授課方式。這個(gè)單元的題目是Making the news。應(yīng)該是學(xué)生比較感興趣的話題,學(xué)生往往對(duì)新聞工作充滿好奇,所以我們可以利用這個(gè)機(jī)會(huì)多設(shè)計(jì)一些師生互動(dòng)和學(xué)生互動(dòng),來(lái)激發(fā)起學(xué)習(xí)的積極性,提高學(xué)習(xí)效率。同時(shí)我們可以利用這個(gè)單元不僅幫助學(xué)生掌握語(yǔ)言知識(shí),培養(yǎng)語(yǔ)言能力,同時(shí)讓其了解新聞工作的重要性,培養(yǎng)起社會(huì)智能感。這個(gè)單元分為六個(gè)課時(shí),它的教學(xué)目標(biāo)是這樣的:語(yǔ)言目標(biāo)是掌握詞匯表中的常用單詞和短語(yǔ),掌握倒裝句的一些基本用法。 技能目標(biāo)是能初步掌握約會(huì)的基本句型并在真實(shí)的場(chǎng)景下正確運(yùn)用。新聞報(bào)道類文章的寫(xiě)作技能。采訪的基本規(guī)范和溝通技能。情感目標(biāo)是對(duì)新聞報(bào)道的客觀性和真實(shí)性有更好的理解。對(duì)新聞?dòng)浾叩穆殬I(yè)有更深入的了解,并能體會(huì)其工作的重要性。下面我們來(lái)介紹一下第一課時(shí)的授課方式,第一課的教學(xué)目標(biāo)是這樣的第一課時(shí)的教學(xué)目標(biāo)語(yǔ)言目標(biāo):單詞:Occupation, journalist, editor, photographer, curious, personality, enthusiasm
3.請(qǐng)幾組同學(xué)表演這幾個(gè)的場(chǎng)面,其他同學(xué)做評(píng)委,從模仿表演中享受學(xué)習(xí)音樂(lè)的快樂(lè)。五.課堂小結(jié) (階段目標(biāo):以“我的收獲”(課件十)幫助學(xué)生總結(jié)所學(xué)內(nèi)容,知道音樂(lè)中,不同的音樂(lè)要素可以表現(xiàn)不同的人物、場(chǎng)面)課后反思:(課件十一)在本節(jié)音樂(lè)欣賞教學(xué)中,我堅(jiān)持以“聽(tīng)”為核心(因?yàn)橐魳?lè)是一門(mén)聽(tīng)覺(jué)藝術(shù)),讓學(xué)生“帶著問(wèn)題聽(tīng)”、“想著聽(tīng)”、“動(dòng)著聽(tīng)”、“演著聽(tīng)”等多元化的“聽(tīng)”的形式。一系列“聽(tīng)”的任務(wù)不僅提高學(xué)生的注意力,而且提高學(xué)生“聽(tīng)”的興趣與“聽(tīng)”的質(zhì)量。而且我創(chuàng)造和諧的課堂氣氛,積極引導(dǎo)學(xué)生把對(duì)音樂(lè)的內(nèi)心感受大膽地用語(yǔ)言表達(dá)出來(lái),讓學(xué)生主動(dòng)參與音樂(lè)快樂(lè)學(xué)習(xí)的實(shí)踐中去,創(chuàng)建出有利于學(xué)生發(fā)展的生動(dòng)活潑的音樂(lè)課堂情景,讓學(xué)生的了解音樂(lè),感受音樂(lè),融入音樂(lè)。
三、聆聽(tīng)、表演《小寶寶睡著了》 1、聆聽(tīng)歌曲啟發(fā)學(xué)生說(shuō)說(shuō)聽(tīng)到歌曲時(shí)感受到了什么?2、復(fù)聽(tīng),跟著歌曲,輕柔地拍節(jié)拍。 3、聽(tīng)琴聲逐句學(xué)唱歌曲。 4、指導(dǎo)學(xué)生用連貫、輕柔的聲音,唱準(zhǔn)、唱好歌曲。 5、重點(diǎn)引導(dǎo)學(xué)生說(shuō)說(shuō)結(jié)尾的處理方式——對(duì)比練習(xí),看哪一種方法更恰當(dāng) 6、引導(dǎo)學(xué)生用自己創(chuàng)作的方式為歌曲伴奏、伴舞。 四、小結(jié)。 教學(xué)反思:一年級(jí)課堂上會(huì)有一些學(xué)生在上課的時(shí)候出現(xiàn)喊唱的現(xiàn)象,我在歌曲處理這一環(huán)節(jié)對(duì)歌曲的意境作了這樣的描述:靜靜的夜晚,天上的星星睡了、月亮睡了、地上的鳥(niǎo)兒、蟲(chóng)兒也都進(jìn)入了夢(mèng)鄉(xiāng),小寶寶也在悠蕩的搖籃里,聽(tīng)著媽媽甜美的歌聲,漸漸入睡了。同學(xué)們媽媽哄寶寶睡覺(jué)唱歌的聲音應(yīng)該是歡快的,還是輕柔的?經(jīng)過(guò)我的描繪和講解學(xué)生理解了在演唱搖籃曲時(shí)應(yīng)該用輕柔的聲音,要把每一句都連貫的唱起來(lái),不僅句與句之間要連貫,第一、第二段也要銜接緊湊,輕輕的哼唱出來(lái),體會(huì)媽媽哄小寶寶睡覺(jué)時(shí)是多么的溫柔。
3、用木魚(yú)來(lái)演奏音樂(lè)的不同節(jié)奏。(1)師:小動(dòng)物們都能聽(tīng)著音樂(lè)按節(jié)奏走路了,下面我想考考你們能不能用這種樂(lè)器來(lái)演奏不同的節(jié)奏呢。(2) 出示木魚(yú),演示木魚(yú)的演奏方法。師:左手拿木魚(yú),右手拿木棍,敲的時(shí)候要注意不要打在自己的手指上,打在手指上是沒(méi)有聲音的。(3) 玩游戲《聽(tīng)一聽(tīng)》,訓(xùn)練學(xué)生的聽(tīng)辨能力和記憶能力。師:我們先來(lái)玩一個(gè)游戲,老師敲出幾個(gè)不同的節(jié)奏,你們聽(tīng)聽(tīng)哪個(gè)是最慢的,哪個(gè)是最快的,看誰(shuí)的耳朵最靈敏。(4) 學(xué)生練習(xí)演奏木魚(yú),學(xué)會(huì)用木魚(yú)敲出不同的節(jié)奏,教師個(gè)別指導(dǎo)。師:現(xiàn)在就請(qǐng)同學(xué)們自己來(lái)演奏木魚(yú),你可以嘗試著怎樣敲會(huì)快一點(diǎn),怎樣會(huì)慢一點(diǎn)。(木魚(yú)學(xué)生人手一個(gè))[設(shè)計(jì)思路]在分層教學(xué)過(guò)程中,由于個(gè)別學(xué)生的基礎(chǔ)比較差,第一和第二段音樂(lè)的演奏訓(xùn)練還不能完全掌握,所以花的時(shí)間比較長(zhǎng)。導(dǎo)致接下的第三和第四段音樂(lè)的木魚(yú)節(jié)奏訓(xùn)練沒(méi)有時(shí)間完成。我將在第二課時(shí)的復(fù)習(xí)鞏固課上再讓同學(xué)們來(lái)練習(xí)演奏。
課堂上隨機(jī)給出鼓勵(lì)和肯定的語(yǔ)言更顯教師的親和力,營(yíng)造出一個(gè)自由、民主的課堂教學(xué)氛圍。如:“你很棒”“說(shuō)得太好了”“掌聲鼓勵(lì)”等等,聽(tīng)似平淡無(wú)奇,但結(jié)合那時(shí)那景則顯得老師語(yǔ)言的樸實(shí)與自然,學(xué)生同老師間的默契與和諧。聽(tīng)完朱老師執(zhí)教的《西風(fēng)的話》一課,通過(guò)認(rèn)真反思我真切認(rèn)識(shí)到:一堂好課是否愉悅高效,就看教師是否真正用心的地去詮釋作品,真正用心地去備課。孫老師執(zhí)教的《西風(fēng)的話》平實(shí)、淡雅,教師教態(tài)自然大氣,言談中充滿著激情,讓我們的心不自覺(jué)跟著一起走。我想不出什么華麗的詞藻來(lái)描述這堂課,但我卻深深地被吸引,這應(yīng)該就是生命課堂的魅力所在吧。聽(tīng)了孫老師執(zhí)教的《西風(fēng)的話》后收獲很多,能于言表的也還沒(méi)有表達(dá)充分,但更多的是帶給我的觸動(dòng)和對(duì)自己所教學(xué)科如何“高效愉悅”的思索。也希望憑借著“高效愉悅”課堂活動(dòng)的深入開(kāi)展,讓自己的美術(shù)課堂靈動(dòng)起來(lái),讓我們的課堂真正成為孩子們探求知識(shí)的樂(lè)園。
一、教材分析:本節(jié)課選自北京師范大學(xué)教育出版社七年級(jí)上冊(cè)第五章第三節(jié),是學(xué)生學(xué)習(xí)一元一次方程的含義,并掌握了解法后,通過(guò)分析圖形問(wèn)題中的數(shù)量關(guān)系,建立一元一次方程并用之解決實(shí)際問(wèn)題,是學(xué)生運(yùn)用數(shù)學(xué)知識(shí)解決生活中實(shí)際問(wèn)題中的典型素材,可提高學(xué)生解決問(wèn)題的能力,提高學(xué)習(xí)數(shù)學(xué)的興趣,形成學(xué)以致用的思想,認(rèn)識(shí)方程運(yùn)用模型的重要環(huán)節(jié)。二、學(xué)情分析:通過(guò)前幾節(jié)解方程的學(xué)習(xí),學(xué)生已經(jīng)掌握了解、列方程的基本方法,在此過(guò)程中也初步掌握了運(yùn)用方程解決實(shí)際問(wèn)題的一般過(guò)程,基本會(huì)通過(guò)分析簡(jiǎn)單問(wèn)題中已知量與未知量的關(guān)系列出方程解應(yīng)用題,但學(xué)生在列方程解應(yīng)用題時(shí)常常會(huì)遇到從題設(shè)條件中找不到所依據(jù)的等量關(guān)系,或雖能找到等量關(guān)系,但不能列出方程這樣的問(wèn)題,因此,在教師的引導(dǎo)下,通過(guò)學(xué)生親自動(dòng)手制作模型,自主探索在模型變化過(guò)程中的等量關(guān)系,建立方程,從而將圖形問(wèn)題代數(shù)化。
(三)實(shí)踐操作,表現(xiàn)歌曲。課標(biāo)中指出,“表現(xiàn)是實(shí)踐性很強(qiáng)的音樂(lè)學(xué)習(xí)領(lǐng)域,是學(xué)習(xí)音樂(lè)的基礎(chǔ)性內(nèi)容,是培養(yǎng)學(xué)生音樂(lè)表現(xiàn)能力和審美能力的重要途徑?!痹偌由蠈?duì)于這個(gè)年齡段的學(xué)生來(lái)講,他們特別喜歡表現(xiàn)自己,所以,我充分發(fā)揮集體的力量,設(shè)計(jì)“小小音樂(lè)家”的教學(xué)環(huán)節(jié),讓同學(xué)們?cè)谛〗M中合作學(xué)習(xí),采用不同形式演唱、用打擊樂(lè)器伴奏、歌舞表演等形式將唱、奏結(jié)合,唱、演結(jié)合,鞏固學(xué)生對(duì)歌曲的學(xué)習(xí),體驗(yàn)合作學(xué)習(xí)的快樂(lè),養(yǎng)成學(xué)生共同參與的群體意識(shí)和相互尊重的合作精神和實(shí)踐能力,這也更體現(xiàn)了課標(biāo)中音樂(lè)課程價(jià)值所提出的要培養(yǎng)學(xué)生的“社會(huì)交往價(jià)值”。(四)拓展延伸,創(chuàng)編歌曲。課標(biāo)中的“文化傳承價(jià)值”中明確提出:“要讓孩子們通過(guò)學(xué)習(xí)世界上其他國(guó)家和民族的的音樂(lè)文化,拓寬他們的審美視野,認(rèn)識(shí)世界各民族音樂(lè)文化的豐富性和多樣性,增進(jìn)對(duì)不同文化的理解、尊重和熱愛(ài)?!?/p>
2學(xué)情分析 通過(guò)本課的學(xué)習(xí),調(diào)動(dòng)和激發(fā)學(xué)生參與學(xué)習(xí)活動(dòng)的熱情,使學(xué)生在游戲活動(dòng)中通過(guò)教師的引導(dǎo)及自己動(dòng)手實(shí)踐的親身體驗(yàn),感知泥性并自我解決如何使泥巴聽(tīng)話,如何玩出新的方法這一問(wèn)題。同時(shí),在教師的鼓勵(lì)下,使學(xué)生能大膽自由的進(jìn)行造型活動(dòng)并大膽發(fā)表自我感受。3重點(diǎn)難點(diǎn) 1.探索感知泥性,歸納玩泥的幾種方法。2.感受、探索、泥性及口頭表達(dá)。
