    人教版高中語文必修3《愛的奉獻 學習議論中的記敘》說課稿

    教學過程:(一)導入:課前放《愛的奉獻》歌曲,同時不斷播放一些有關“愛”的主題的圖片,渲染一種情感氛圍。師說:同學們,誰能說說這組圖片的主題應該是什么?生(七嘴八舌):母愛,不對是親情……是友情、還有人與人互相幫助……那組軍人圖片是說保衛(wèi)國家,應該是愛國……那徐本禹和感動中國呢?…………生答:是關于愛的方面師說:不錯,是關于愛的方面。那么同學們,今天就以“愛的奉獻”為話題,來寫一篇議論文如何?生答:老師,還是寫記敘文吧。生答:就是,要不議論文寫出來也象記敘文。師問:為什么?生答:老師,這個話題太有話說了,一舉例子就收不住了,怎么看怎么象記敘文。生答:就是,再用一點形容詞,就更象了。眾人樂。師說:那么同學們誰能告訴我,為什么會出現這種問題?一生小聲說:還不是我們笨,不會寫。師說:不是笨,也不是不會寫,你們想為什么記敘文就會寫,一到議論文就不會了,那是因為同學們沒有明白議論文中的記敘與記敘文中的記敘有什么不同,所以一寫起議論文中的記敘,還是按照記敘文的寫法寫作,這自然就不行了。那好,今天我們就從如何寫議論文中的記敘講起。

  • 人教版高中地理必修1第一章第一節(jié)宇宙中的地球說課稿

    人教版高中地理必修1第一章第一節(jié)宇宙中的地球說課稿

    (一)教材的地位與作用本節(jié)描述地球所處的宇宙環(huán)境包括兩部分內容,一是能在天體系統(tǒng)中確定地球所在位置,二是結合太陽燃燒的穩(wěn)定狀態(tài)和大行星運軌道特征,說明地球存在生命的宇宙環(huán)境特征。這里需要補充太陽大小長期穩(wěn)定的燃燒保證地球表面長期保持適宜的溫度,有利生命進化;大小行星公轉各行其道,保證地球宇宙環(huán)境的安全。這兩點宜在討論地球是特殊的行星時補充。說明地球是太陽系中一顆既普通又特殊的行星要通過 3引導學生從圖文資料中找出地球與其他行星在運動特征和結構特征上的共性以及軌道位置和自身條件上的特性。運動特征共性包括同向性、共面性和近圓性;結構特征主要是通過與類地行星比較得出地球在質量和體積方面不具特殊性。地球上存在生命主要是因為日地距離適中,所以有適合的溫度;因為地球質量和體積適中,所以能吸引住大氣形成厚度、壓力適合的大氣層;因為地球存在巖漿活動,所以有地球內部氫氧分異化合的水汽溢出形成海洋。

    四.設計反思我在設計本課時,希望通過情境的創(chuàng)設充分再現歷史,并利用多媒體輔助教學,破重點、化難點,讓學生主動參與到學習過程中,從而突破狹小的教室空間,讓學生真正做到感知歷史,立足現實,展望未來。自主,交流、合作、探究是課程改革中著力倡導的新型學習方式。課堂教學中如何開展小組合作的探究學習存在著很多困難,首先是課堂教學時間有限,如何體現面向全體,給每個學生以機會?再次,歷史問題的討論只能依托于史料才能使討論不淪為空談,課堂上通過網絡提供大量的史料(文字、圖片或其他),勢必不能有充分時間讓學生閱讀分析。如何解決這些問題呢?措施一:要形成較固定的歷史學習合作小組。選定一位同學擔任組長,負責協(xié)調措施二:要設置有利于學生探究的問題情境措施三:要把課堂教學與課外學習結合起來。在課前就印發(fā)相關的材料,或引導學生去查閱相關的資料,讓學生有個充分的閱讀、思考、交流的時間,是保證課堂上小組交流能成功實現的一個前提

    人教版高中生物必修1細胞核—系統(tǒng)的控制中心說課稿

    首先引導回顧細胞質內各個細胞器的分工協(xié)作、產生分泌蛋白的過程;同時思考:為什么這些細胞器可以這樣有條不紊的密切協(xié)作?這中間有沒有專門起協(xié)調和控制作用的部門?從而導入本節(jié)內容。通過學生小組討論及師生共同分析“資料分析”中的4個實驗,總結出細胞核的功能,即細胞核是遺傳信息庫,控制細胞代謝和遺傳的功能。在此基礎上,向學生舉出克隆羊多莉的實例,加強理解。設問:那么細胞核為什么能成為細胞代謝和遺傳的控制中心?要弄清這個問題,我們必須從細胞核的結構中尋找答案,從而引出細胞的結構。在這部分,引導學生思考以下幾個問題:(1)細胞核能控制細胞的遺傳,說明其應該有什么物質?(2)含有DNA的結構如線粒體、葉綠體,它們的外面都有什么相同的結構?(3)細胞核能控制細胞,肯定能與外界聯(lián)系,如何能辦到?(4)學習RNA的分布時,RNA主要分布在細胞質,少量還分布在哪里呢?

    Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …h(huán)orse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.
