    人教版高中語文必修3《宇宙的邊疆》說課稿2篇

    (有的恒星旋轉(zhuǎn)平穩(wěn)均衡,有些恒星是因快速旋轉(zhuǎn)而變了形。作者以擬人的手法,生動形象地描述,仿佛向我們展示了不同恒星的性情:有的穩(wěn)重沉靜,有的急切躁動。讀來生動有趣,妙趣橫生。)(3)我們探索宇宙的時候,既要勇于懷疑,又要富于想象。想象經(jīng)常能夠把我們帶領到嶄新的世界,沒有想象,我們就處處碰壁。懷疑可以使我們擺脫幻想,還可以檢驗我們的推測。(對于未知領域的探索是需要懷疑和想象的,想象是科學的翅膀,敢于想象,并不斷地探索驗證,所謂“大膽假設,小心求證”懷疑否定舊知,產(chǎn)生新知。作者以簡潔的語言闡述了想象和懷疑看似矛盾的兩者在宇宙探索中的相輔相成,和諧統(tǒng)一。作者不囿于介紹宇宙知識,還發(fā)表自己的見解。)(4)我認為宇宙里很可能到處都充滿著生命,只是我們?nèi)祟惿形窗l(fā)現(xiàn)而已。我們的探索才剛剛開始。

    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.

    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

Through the training of the unit, it also requires students to learn some Language skills such as the expressions of position and emotions.So it plays an important part in the English teaching in this book.After studying the teaching material and analyzing the rule of children’s growing of mind,I think the teaching aims are the followings:1.Knowledge objects:(1) make the students learn some new words and phrases(2) make the students understand the content of the lesson.2.Ability objects:(1)To develop the Ss’ abilities of listening, speaking, reading and writing. Especially reading and speaking ability.(2) learn to talk about the characters of Canada in English(3)To train the Ss’ ability of working in pairs.3.Emotion objects:(1)Enable students to understand the characters of Canada..(2)Stimulate Ss to work hard to make China stronger.Part 2 Teaching Methods:I think helping students learn to master new words and phrases and improve the students’ reading and speaking ability is import and the difficult.According to the analysis of the teaching material and the import points and the difficult points,I will use the following teaching methods : question-guiding approach; fast-reading and careful reading; multi-media teaching methods; discussion

    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.

    四、教學方法和學法。課前學生搜集有關《詩經(jīng)》的資料必不可少。另外,時隔數(shù)千年,年代久遠,文字的障礙很大,然而,過分糾纏于文字的疏通會破壞詩歌的“氣”,喪失詩歌的“神”,所以在學習時,應舍去條分縷析的理論評價,指導學生結(jié)合注釋疏通文字,然后引領他們經(jīng)由文字再現(xiàn)形象和事件,經(jīng)由形象和事件領略情感,感受其中濃濃的詩情。誦讀的環(huán)節(jié)是重要的,配以二胡獨奏《長相思》,營造意境,學生沉浸在音樂營造的意境中反復吟詠,讀出節(jié)奏,讀出音調(diào),讀出感情,細細體味,讓或優(yōu)或喜的情愫縈繞心間,我們就觸到了先民的靈魂。比興手法為《詩經(jīng)》獨創(chuàng),重章疊句同樣別致而新鮮,教學過程中結(jié)合具體語境讓學生自己去發(fā)現(xiàn)并進行討論,不搞枯燥的知識傳授。還引入講故事、改寫兩種活潑的學習形式,從而達到加深理解的目的。

    (二)分析課文,理清思路第1、2段為第一部分,主要是敘事、寫景,先敘述集會的時間、地點,然后渲染出蘭亭優(yōu)美的自然環(huán)境。在這里足以“游目騁懷”“極視聽之娛”,可以自由地觀察、思考,滿足人們目視耳聞的需求。這里正是與會“暢敘幽情”、盡興盡歡的絕好處所。這些描寫都富有詩情畫意,作者的情感是輕松愉快的。第3、4段為第二部分,主要是抒情、議論,作者由美景妙時引發(fā)出樂與憂、生與死的感慨。他認為人生的快樂是有極限的,待快樂得到滿足時,就會感覺興味索然。往事轉(zhuǎn)眼間便成為歷史,人到了生命的盡頭就會死亡。作者由“一死生為虛誕,齊彭殤為妄作”的認識,產(chǎn)生了一種珍惜時間、眷戀生活、熱愛文明的思考。雖然文中的壽夭、生死不能自由決定,從而有些傷感,但作者仍然認識到盛衰、生死是必然的。人生無常,時不我待,故著文留傳后世,以承襲前人,啟示來者。

    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?!队晗铩肥乾F(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

    人教版高中政治必修1市場配置資源說課稿

    (2)、市場調(diào)節(jié)存在固有的弊端:自發(fā)性:由于市場調(diào)節(jié)是在價值規(guī)律自發(fā)作用下進行的,在利益驅(qū)動下會產(chǎn)生一些違反市場原則的行為,如制造、銷售假冒偽劣商品,大量排放廢水、廢氣破壞環(huán)境,竊取他人智力成果等等。盲目性:由于人們不可能完全掌握生產(chǎn)各方面信息及其變化趨勢,致使決策帶有一定的盲目性。如某種商品有利可圖則一哄而上,反之則一哄而退,從而造成資源浪費和消費得不到充分滿足。滯后性:由于市場價格的形成和傳遞有一個過程,一旦傳遞到生產(chǎn)經(jīng)營者手中進行生產(chǎn)調(diào)整,就有一個時間差,致使市場調(diào)節(jié)帶有滯后性,成為一種事后調(diào)節(jié)。教師活動:請同學們想一想,市場的這些弊端和不足,會導致什么后果?(3)、危害教師總結(jié):資源浪費,經(jīng)濟波動與混亂,分配不公兩極分化等。設計意圖:通過創(chuàng)設情景,加深對市場調(diào)節(jié)局限性的理解;要求學生結(jié)合生活實例探討其弊端有助于加強對其產(chǎn)生原因和表現(xiàn)的記憶和理解。
