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!

三、說學法學生是學習的主體,應在學習中充分發(fā)揮自己的主體能動作用,所以本節(jié)課學生主要采用以分組實踐、自主探究、合作交流為主要形式的“探究學習法”,目的是通過豐富多彩的小組活動,觀察實踐,以合作學習促進自主探究。首先是小組合作觀察藥箱和其他立體圖形的活動,我先讓小組成員獨立思考,然后組內討論交流,達成共識,最后小組成員一齊操作。然后是小組議一議的活動,老師先引導學生:關于觀察物體,你有什么新發(fā)現(xiàn)?學生在獨立思考的基礎上討論交流,各抒己見,共同促進。組與組之間也有交流。學生合作過程中,教師適當?shù)膯l(fā)、引導,學生的學習方式主要是自主、合作和探究性的。
這一活動把現(xiàn)實和情景結合起來,讓學生真正領悟如何愛護動物,保護大自然,動物是我們的朋友,我們應該和動物互相依存,共同生活在這個世界上,誰也離不開誰?;顒尤何沂钦娴南矚g你們1、出示生活中孩子們對待動物的錯誤方式。讓孩子們討論今后我們應該怎么做。2、對孩子們的回答進行引導,教會孩子們如何去愛護動物。3、抓住典型,使學生明白喜歡動物不是單純的覺得自己對動物好就是喜歡,而是從動物本身出發(fā),想想動物它們到底需要什么。這三項活動具有連續(xù)性,主要是引導學生從生活中明白如何去愛護動物,保護大自然,理解怎樣才是真正的喜歡。(三)拓展延伸1、孩子們,動物也有發(fā)脾氣的時候,如果我們遇到了這樣的情況,你們知道如何應對嗎?2、出示與動物相處時的注意事項。拓展孩子們的課外知識。五、說板書設計根據(jù)一年級學生的年齡特點,我采取直觀形象的板書,使學生一目了然地知道學習步驟,引導學生愛護動物,保護大自然。

尉氏鴨蛋及養(yǎng)鴨基地賈魯河畔尉氏燴面是河南燴面的一個重要分支,與其它地方不同的是尉氏燴面是羊肉濃湯鍋中下面并取湯,尉氏燴面是以獨家祖?zhèn)髅胤秸{制的香料配上滾滾的羊湯而成。放入羊肉丁、蔥花、香菜或是五香菜,芝麻醬,同時以個人口味放入用牛羊油潑的油辣椒,濃香味美、回味無窮······人們說到尉氏縣洧川鎮(zhèn),首先想到的一定會是洧川豆腐。有許多人也是因為洧川豆腐,才認識了洧川鎮(zhèn)。因為這小小的豆腐在洧川鎮(zhèn)的周邊縣市實在太有名了,迄今已有2000多年的歷史。 洧川豆腐與眾不同之處在于其表面呈琥珀色,切刀處為純白色,韌性十足,能用麻繩串起來,可用秤鉤掛著稱,放在鍋里越煮越筋,烹炸煎炒則風味各異。由于洧川豆腐的制作一直采用傳統(tǒng)工藝,2011年,洧川豆腐被評為河南省非物質文化遺產(chǎn)。
《采茶》是大班下學期的韻律活動,這4曲子分為四個樂句,講述了春光明媚,采茶姑娘高高興興走到茶園,忙著采茶的歡快場面。音樂節(jié)奏歡快,每一句都以長音結尾,讓幼兒比較容易地區(qū)分樂句?,F(xiàn)在正是春暖花開,茶香飄逸的時期,蘇州名茶“碧螺春”已家喻戶曉。前兩天還組織了幼兒到東山茶莊去親自嘗試了采茶、制茶、品茶的活動。為了能進一步深化這次實踐活動的教育功能,表達幼兒的內心體驗,我選擇了這個教材,讓幼兒將生活化的動作向著細膩化的表達?!毒V要》明確地強調,豐富幼兒的藝術活動的能力是在大膽表現(xiàn)的過程中逐漸發(fā)展起來的,教師的作用在于激發(fā)幼兒感受美、表現(xiàn)美的情趣,豐富他們的審美經(jīng)驗,使之體驗自由表達和創(chuàng)造的快樂。我班有部分幼兒信心不足不愿意表演給別人看,特別是韻律活動中,孩子們大部分趨向模仿教師的示范,創(chuàng)新意識不強。
能正確、流利、有感情地朗讀課文,背誦課文,并學習生字,積累詞語。???????????????(2)過程與方法目標:借助多媒體課件等資源,創(chuàng)設情境,引領學生自主探究,互動交流,在讀中理解,讀中感悟。? (3)情感態(tài)度與價值觀目標:體會紅軍大無畏的英雄氣概和革命樂觀主義精神。? ?三、說教學重難點:? 1.抓住重點詩句品讀感悟,體會紅軍大無畏的英雄氣概和革命樂觀主義精神。?2.理解本詩高度的藝術概括性和極度夸張的手法。?四、說教法這首詩的時代背景是紅軍長征時期,離學生的生活年代比較遠,學生要把握詩中的思想感情有一定的難度。根據(jù)學生實際情況和課文特點,我主要采用“情境教學法”和“朗讀體會法”,即通過反復朗讀,讓學生讀出詩的韻味,在讀中理解詩意,在讀中感受毛主席及其領導的中國工農紅軍大無畏的革命精神和英勇豪邁的氣概,達到熟讀成誦的效果。另外,利用創(chuàng)設情境法,將學生帶入特定的歷史背景中,讓學生合作學習、小組交流,為學生營造了一個和諧的課堂氛圍。
1.展示海洋魚類圖片,并導入課題。師:夏季炎熱的天氣已經(jīng)開始了,老師帶來了一份涼爽禮物想送大家,你們猜猜是什么呢?生:……師:想知道嗎?這份禮物就是幾張美麗的圖片,請看大屏幕:在深藍色的海底世界里,一群可愛的海洋魚在悠閑地游來游去,好涼快,好舒服呀。喜歡這個禮物嗎? 生:…… 師:喜歡呀,老師太高興了。同學們再來看一看,在這幾張漂亮的圖片里,除了讓我們感受到大海的涼爽和美麗之外,你還發(fā)現(xiàn)什么了嗎?
2學情分析這是一個學生比較感興趣的內容,通過學習不僅能提高學生的學習欲望,更希望能根據(jù)一句話或者一段話以畫畫的形式表現(xiàn)出來。3重點難點重點:了解繪畫故事的表現(xiàn)特點,感受真、善、美。繪畫自編故事的創(chuàng)作特點及步驟。難點:選材、構思設計、構圖與繪制。
2學情分析四年級的學生正處于素質教育的階段,學生對美術正逐步深入了解,并掌握了一些美術基礎知識和基本技能,多數(shù)同學對美術興趣濃厚,有較強的求知欲和教強的創(chuàng)新力,學生的美術素質得到進一步提高。3重點難點教學重點:讓學生從大自然和生活的萬物中發(fā)現(xiàn)線條的幾種變化,發(fā)現(xiàn)圓點在紙上的不同位置產(chǎn)生的不同感覺。
1、游戲法:游戲是幼兒最喜歡的活動,是引導幼兒主動學習的重要方式。在活動中,我設計了讓幼兒《穿衣服比賽》比一比誰最能干。在游戲中使幼兒自然習得對手的認識,知道了手能做許多事情。2、談話法:所謂談話法,就是圍繞活動內容,通過教師提問,引導幼兒回答的一種方法。由于幼兒年齡小,經(jīng)驗少,在引導幼兒認識到自已在一天天長大,要自已動手做事。通過以教師為主,幼兒為輔的談話,師幼進行談話、討論,達成共識完成教育目標。3、經(jīng)驗感知法:由于幼兒的經(jīng)驗缺乏又喜歡模仿,容易在經(jīng)驗分享的現(xiàn)象。所以我精心制作了精美的課件,拓展幼兒的經(jīng)驗,再通過教師適時的引導,幼兒的思路就會打開,經(jīng)驗就能較好的分享,知道很能干,會做許多的事情,并能嘗試著用語言表達出來,這樣能夠有效的化解難點,突破重點。
一、 設計理念新課程標準強調的數(shù)學學習的基本理念之一人人都能獲得良好的數(shù)學教育,不同的人在數(shù)學上得到不同的發(fā)展。基于以上理念,我們必須改革課堂教學中教師始終“講”、學生被動“聽”的局面,將傳統(tǒng)意義上的“學生除了做題還是做題”的“紙筆方式”創(chuàng)造性地設計成學生動手操作方式。充分相信學生,把學習的主動權交給學生,充分調動學生的學習積極性。為此,我在教學設計的時候要力求做到“生活問題數(shù)學化”。始終將數(shù)學的教與學置于各種奇妙的富于思考的問題情境之中,讓學生用腦想數(shù)學,用腦積極地思考數(shù)學或與之有關的問題。這種設計就是很好地貫穿了問題化設計理念。在教學中采用了“引導探索學習,促進主動發(fā)展”的教學方法,讓學生真正成為學習的主人,學會學習,培養(yǎng)學生學數(shù)學,用數(shù)學的情感。
一、情景激趣,引入新課現(xiàn)代心理學告訴我們,直覺、興趣是產(chǎn)生學習動力最活躍的成份,上課開始,我 (設計意圖)在信息技術課的“任務”設計中,要充分發(fā)揮多媒體計算機具有綜合處理圖形、圖像、動畫、視頻以及聲音、文字等多種信息的功能。這樣情境的意圖是激發(fā)學生對這些問題的興趣,使他們帶著激動的情緒去學習和思考。抓住這一契機,我很自然的提示課題。
二、說活動目標幼兒園數(shù)學是一門系統(tǒng)性、邏輯性很強的學科,有著自身的特點和規(guī)律,新《綱要》提出“數(shù)學教育必須要讓幼兒能從生活和游戲中感受事物的數(shù)量關系并體驗到數(shù)學的重要和有趣;教師要引導幼兒對周圍環(huán)境中數(shù)、量、形、時間和空間等現(xiàn)象產(chǎn)生興趣,建構初步的數(shù)概念,并學習用簡單的數(shù)學方法解決生活和游戲中某些簡單的問題。”由此可見生活化、游戲化已經(jīng)成為構建數(shù)學課程最基本的原則。在對教材和本班幼兒的學習情況有一定了解后,我制定出本次活動目標:1、學習5的分解和組成,引導幼兒歸納分合式中兩邊數(shù)列分別是遞增、遞減的關系。2、激發(fā)幼兒主動探索、與同伴交流的興趣。三、說重點難點大班思維中出現(xiàn)抽象邏輯思維的萌芽,在認識事物方面,不僅能夠感知事物的特點,而且能夠進行初步的歸納和推理。因而本次活動的重點:讓幼兒學習5的分解和組成,難點:在此基礎上引導幼兒歸納出分合式中兩邊數(shù)列的關系。四、說教法和學法
