第3篇大班故事教案
once upon a time...
there lived a king who was deeply in love with a princess, but she could not marry anyone, because she was under an enchantment. so the king set out to seek a fairy, and asked what he could do to win the princess"s love. the fairy said to him:"you know that the princess has a great cat which she is very fond of. whoever is clever enough to tread on that cat"s tail is the man she is destined to marry."
the king said to himself that this would not be very difficult, and he left the fairy, determined to grind the cat"s tail to powder rather than not tread on it at all.
you may imagine that it was not long before he went to see the princess, and puss, as usual, marched in before him, arching his back. the king took a long step, and quite thought he had the tail under his foot, but the cat turned round so sharply that he only trod on air. and so it went on for eight days, till the king began to think that this fatal tail must be full of quicksilver it was never still for a moment.
at last, however, he was lucky enough to come upon puss fast asleep and with his tail conveniently spread out. so the king, without losing a moment, set his foot upon it heavily.
with one terrific yell the cat sprang up and instantly changed into a tall man, who, fixing his angry eyes upon the king, said:
"you shall marry the princess because you have been able to break the enchantment, but i will have my revenge. you shall have a son, who will never be happy until he finds out that his nose is too long, and if you ever tell anyone what i have just said to you, you shall vanish away instantly, and no one shall ever see you or hear of you again."
though the king was horribly afraid of the enchanter, he could not help laughing at this threat.
"if my son has such a long nose as that," he said to himself, "he must always see it or feel it; at least, if he is not blind or without hands."
but, as the enchanter had vanished, he did not waste any more time in thinking, but went to seek the princess, who very soon consented to marry him. but after all, they had not been married very long when the king died, and the queen had nothing left to care for but her little son, who was called hyacinth. the little prince had large blue eyes, the prettiest eyes in the world, and a sweet little mouth, but, alas! his nose was so enormous that it covered half his face. the queen was inconsolable when she saw this great nose, but her ladies assured her that it was not really as large as it looked; that it was a roman nose, and you had only to open any history to see that every hero has a large nose. the queen, who was devoted to her baby, was pleased with what they told her, and when she looked at hyacinth again, his nose certainly did not seem to her quite so large.
the prince was brought up with great care; and, as soon as he could speak, they told him all sorts of dreadful stories about people who had short noses. no one was allowed to come near him whose nose did not more or less resemble his own, and the courtiers, to get into favor with the queen, took to pulling their babies" noses several times every day to make them grow long. but, do what they would, they were nothing by comparison with the prince"s.
when he grew sensible he learned history; and whenever any great prince or beautiful princess was spoken of, his teachers took care to tell him that they had long noses.
his room was hung with pictures, all of people with very large noses; and the prince grew up so convinced that a long nose was a great beauty, that he would not on any account have had his own a single inch shorter!
when his twentieth birthday was passed the queen thought it was time that he should be married, so she commanded that the portraits of several princesses should be brought for him to see, and among the others was a picture of the dear little princess!
now, she was the daughter of a great king, and would some day possess several kingdoms herself; but prince hyacinth had not a thought to spare for anything of that sort, he was so much struck with her beauty. the princess, whom he thought quite charming, had, however, a little saucy nose, which, in her face, was the prettiest thing possible, but it was a cause of great embarrassment to the courtiers, who had got into such a habit of laughing at little noses that they sometimes found themselves laughing at hers before they had time to think; but this did not do at all before the prince, who quite failed to see the joke, and actually banished two of his courtiers who had dared to mention disrespectfully the dear little princess"s tiny nose!
the others, taking warning from this, learned to think twice before they spoke, and one even went so far as to tell the prince that, though it was quite true that no man could be worth anything unless he had a long nose, still, a woman"s beauty was a different thing; and he knew a learned man who understood greek and had read in some old manuscripts that the beautiful cleopatra herself had a "tip-tilted" nose!
the prince made him a splendid present as a reward for this good news, and at once sent ambassadors to ask the dear little princess in marriage. the king, her father, gave his consent; and prince hyacinth, who, in his anxiety to see the princess, had gone three leagues to meet her was just advancing to kiss her hand when, to the horror of all who stood by, the enchanter appeared as suddenly as a flash of lightning, and, snatching up the dear little princess, whirled her away out of their sight!
the prince was left quite inconsolable, and declared that nothing should induce him to go back to his kingdom until he had found her again, and refusing to allow any of his courtiers to follow him, he mounted his horse and rode sadly away, letting the animal choose his own path.
so it happened that he came presently to a great plain, across which he rode all day long without seeing a single house, and horse and rider were terribly hungry, when, as the night fell, the prince caught sight of a light, which seemed to shine from a cavern.
he rode up to it, and saw a little old woman, who appeared to be at least a hundred years old.
she put on her spectacles to look at prince hyacinth, but it was quite a long time before she could fix them securely because her nose was so very short.
the prince and the fairy (for that was who she was) had no sooner looked at one another than they went into fits of laughter, and cried at the same moment, "oh, what a funny nose!"
"not so funny as your own," said prince hyacinth to the fairy; "but, madam, i beg you to leave the consideration of our noses--such as they are--and to be good enough to give me something to eat, for i am starving, and so is my poor horse."
"with all my heart," said the fairy. "though your nose is so ridiculous you are, nevertheless, the son of my best friend. i loved your father as if he had been my brother. now he had a very handsome nose!"
"and pray what does mine lack?" said the prince.
"oh! it doesn"t lack anything," replied the fairy. "on the contrary quite, there is only too much of it. but never mind, one may be a very worthy man though his nose is too long. i was telling you that i was your father"s friend; he often came to see me in the old times, and you must know that i was very pretty in those days; at least, he used to say so. i should like to tell you of a conversation we had the last time i ever saw him."
"indeed," said the prince, "when i have supped it will give me the greatest pleasure to hear it; but consider, madam, i beg of you, that i have had nothing to eat today."
"the poor boy is right," said the fairy; "i was forgetting. come in, then, and i will give you some supper, and while you are eating i can tell you my story in a very few words--for i don"t like endless tales myself. too long a tongue is worse than too long a nose, and i remember when i was young that i was so much admired for not being a great chatterer. they used to tell the queen, my mother, that it was so. for though you see what i am now, i was the daughter of a great king. my father----"
"your father, i dare say, got something to eat when he was hungry!" interrupted the prince.
"oh! certainly," answered the fairy, "and you also shall have supper directly. i only just wanted to tell you----"
"but i really cannot listen to anything until i have had something to eat," cried the prince, who was gettin
g quite angry; but then, remembering that he had better be polite as he much needed the fairy"s help, he added:
"i know that in the pleasure of listening to you i should quite forget my own hunger; but my horse, who cannot hear you, must really be fed!"
the fairy was very much flattered by this compliment, and said, calling to her servants:
"you shall not wait another minute, you are so polite, and in spite of the enormous size of your nose you are really very agreeable."
"plague take the old lady! how she does go on about my nose!" said the prince to himself. "one would almost think that mine had taken all the extra length that hers lacks! if i were not so hungry i would soon have done with this chatterpie who thinks she talks very little! how stupid people are not to see their own faults! that comes of being a princess: she has been spoiled by flatterers, who have made her believe that she is quite a moderate talker!"
meanwhile the servants were putting the supper on the table, and the prince was much
amused to hear the fairy who asked them a th
第4篇大班故事教案
九年義務(wù)教育人教版第5冊(cè)的課文《一個(gè)小村莊的故事》。這篇課文講述了一個(gè)美麗的小村莊,由于村里的人們不加節(jié)制地砍伐樹木,周圍環(huán)境遭到了嚴(yán)重的破壞,最后受到了大自然嚴(yán)厲的懲罰整個(gè)小村莊都被咆哮的洪水卷走了,那個(gè)美麗而寧?kù)o的小村莊從此消失的無(wú)影無(wú)蹤。它告訴了人們要愛護(hù)樹木,保護(hù)大自然的生態(tài)環(huán)境。
整組課文都是圍繞著保護(hù)環(huán)境為主題,通過(guò)質(zhì)樸、深蘊(yùn)的語(yǔ)言,優(yōu)美真實(shí)的課件演示,將學(xué)生帶入了一個(gè)全新的視野窗口,從這個(gè)窗口里他們看到了歷史環(huán)境的巨大變遷,激發(fā)了他們內(nèi)心強(qiáng)烈的的情感共鳴,深深感受到環(huán)境保護(hù)的重要性,從而深化了主題。下面我把它從教材、教法與學(xué)法、教學(xué)過(guò)程、以及教學(xué)板書這個(gè)方面進(jìn)行說(shuō)課。
一、教材分析
首先我說(shuō)說(shuō)教材。根據(jù)新課程標(biāo)準(zhǔn),本組課文訓(xùn)練的主要意圖,和學(xué)生的實(shí)際,我們確定了本課的教學(xué)目標(biāo)。
知識(shí)目標(biāo):有感情的朗讀課文,通過(guò)朗讀,交流、體會(huì)含義深刻的句子,悟出課文中蘊(yùn)含的道理。
技能目標(biāo):培養(yǎng)學(xué)生結(jié)合句子聯(lián)系上下文理解詞語(yǔ)的能力
情感目標(biāo):教育學(xué)生從小熱愛大自然、保護(hù)大自然。
發(fā)展目標(biāo):培養(yǎng)學(xué)生愛護(hù)家園、保護(hù)環(huán)境、為后人造福的憂患意識(shí)。
二、教學(xué)重點(diǎn):
它采用了設(shè)置懸念的方式,引發(fā)學(xué)生的創(chuàng)造思維,因此我們認(rèn)為這篇課文的教學(xué)重點(diǎn)是了解小村莊變化的原因。
三、教學(xué)難點(diǎn):
體會(huì)課文中蘊(yùn)含的道理是本課的教學(xué)難點(diǎn)。
四、教法和學(xué)法:
在這堂課中,我們綜合了觀察法、談話法、討論法、隨機(jī)通達(dá)教學(xué)、自上而下教學(xué)設(shè)計(jì)及情境性教學(xué)方法來(lái)引導(dǎo)學(xué)生自學(xué)、討論、交流。
五、教學(xué)過(guò)程
在本課的教學(xué)中,我們采用了自主學(xué)習(xí)、合作探究的教學(xué)方式,實(shí)踐與想象充分結(jié)合的教學(xué)方法,為學(xué)生營(yíng)造了一個(gè)新型的良好的課堂氛圍。為達(dá)到本課的教學(xué)目標(biāo),主要從四個(gè)方面進(jìn)行教學(xué)。
?。ㄒ唬?chuàng)設(shè)情境,激活情感
在這里,一個(gè)山清水秀、鳥語(yǔ)花香的小村莊在老師的故事中娓娓而來(lái),通過(guò)直觀畫面,直接刺激學(xué)生的視覺思維,首先學(xué)生感受到美的氛圍。然后畫面急劇變化,突如其來(lái)的洪水毀掉了這個(gè)美麗的村莊,從聲音、畫面方面激活學(xué)生潛在的情感。讓他們的思維處于一種張開的狀態(tài),在他們幼小的心靈里,感受到村莊從美麗到毀滅的`過(guò)程給他們帶來(lái)的那種震撼心靈的感覺。第一次與大自然進(jìn)行心靈碰撞為他們理解村莊的消失奠定了情感基礎(chǔ)。
?。ǘ⒛M調(diào)查,滲透新知
在學(xué)生自由讀課文的基礎(chǔ)上,深入了解小村莊變化的原因。并且采用新穎而獨(dú)特的教學(xué)方法激發(fā)學(xué)生的興趣和強(qiáng)烈的求知欲。在教學(xué)中,課件演示讓學(xué)生看到了一個(gè)色彩斑斕的情感畫卷。在這個(gè)時(shí)候,學(xué)生的心里一定有很多的疑問,很多的想法,再運(yùn)用模擬調(diào)查的方式,首先激起學(xué)生的興趣,小學(xué)生的情感極易受環(huán)境氣氛和他人情感的感染而產(chǎn)生共鳴,學(xué)生通過(guò)剛才的課件觀看,聽老師逐步深入的引導(dǎo),拉近了學(xué)生與課文之間的時(shí)空距離。學(xué)生心里那么多的問號(hào)就會(huì)在他們自己的探索中一步一步的清晰、明顯。
?。ㄈ?、自主釋疑,知識(shí)反饋。
《新課程標(biāo)準(zhǔn)》提出,小學(xué)語(yǔ)文教學(xué),應(yīng)立足于促進(jìn)學(xué)生的發(fā)展,使他們成為語(yǔ)文學(xué)習(xí)的主人,在這課里,要引導(dǎo)學(xué)生根據(jù)單元訓(xùn)練目標(biāo),讓學(xué)生提問,把學(xué)習(xí)的主動(dòng)權(quán)放給學(xué)生,這樣做,為學(xué)生指明了方向,也體現(xiàn)了教師的主導(dǎo)作用。在這個(gè)教學(xué)步驟中,我們以課堂為主陣地,始終將分組討論、合作交流作為一種激活課堂信息交流、促進(jìn)學(xué)習(xí)目標(biāo)達(dá)成的有效教學(xué)方式。首先是討論前留出足夠的時(shí)間給學(xué)生,讓學(xué)生開展觀察思考,比如:什么都沒有了所有靠斧頭得到的一切包括那些鋒利的斧頭。。學(xué)生經(jīng)過(guò)有目的地觀察和有意識(shí)地思想,有針對(duì)性去討論,對(duì)問題產(chǎn)生了獨(dú)特的想法,才能充分、深刻地發(fā)表自己的見解。弄明白所有靠斧頭得到一切不僅僅指前面提到的用斧頭得到的房子、家具還有靠斧頭得到的所有不錯(cuò)的生活。討論中學(xué)生都有各不相同的想法,有的是成熟的見解,有的僅僅是幼稚的疑問。這些想法,都使學(xué)生有一種一吐為快的心理需求,此時(shí),正是討論的最佳時(shí)機(jī)。討論時(shí),引導(dǎo)學(xué)生有序地發(fā)言,特別注意讓只習(xí)慣于說(shuō)的學(xué)生有聽的耐心,使羞于發(fā)言的學(xué)生有講的信心,從而使每個(gè)學(xué)生都能有條理地將自己的意見充分表露,使課堂討論呈現(xiàn)一種個(gè)性思想展現(xiàn),交流意識(shí)濃厚的良好氛圍。討論后,再引導(dǎo)學(xué)生進(jìn)行整理,對(duì)于這些意見的聯(lián)結(jié)點(diǎn),讓學(xué)生從中歸納出正是因?yàn)檫@些村民亂砍亂伐,造成了對(duì)周圍環(huán)境的破壞,最終受到了大自然的懲罰,由此看出保護(hù)環(huán)境的重要性。然后讓學(xué)生通過(guò)多種形式的讀,來(lái)體會(huì)文章中所蘊(yùn)含的深刻道理。
(四)、發(fā)展思維、深化主題
孩子們對(duì)大自然總是有一種莫名的親近,而且還有著意想不到的創(chuàng)造潛能。學(xué)完全文后,采用記者采訪的形式,讓學(xué)生談?wù)勛约旱母惺軄?lái)發(fā)展學(xué)生的創(chuàng)造性思維。古人說(shuō):感人心者,先莫乎于情。在這種引放的教學(xué)方式下,教師始終通過(guò)充沛的情感,用生動(dòng)語(yǔ)言掀起學(xué)生情感的波瀾,使自己和學(xué)生的情感融為一體。
六、板書設(shè)計(jì):
這堂課的板書設(shè)計(jì)非常簡(jiǎn)單但又層層進(jìn)入,從直觀上一目了然但又意義深遠(yuǎn),從而深化了整個(gè)主題。
內(nèi)容概括:這篇介紹了關(guān)于《一個(gè)小村莊的故事》說(shuō)課設(shè)計(jì),一個(gè)小村莊的故事,希望對(duì)你有幫助!
