人教版高中歷史必修2物質生活與習俗的變遷說課稿2篇
【課外延伸】閱讀思考：1、改革開放以來，東西方文明的交流、碰撞更加劇烈。對于外來文化，目前有不同的觀點，現引入兩種觀點：觀點1：這是一種進步。改革開放以來，中國不斷發(fā)展，這時候舊的文化顯然是不合時宜的，西方文化的進入，給我們帶來了新的生活方式和生活態(tài)度，中國逐漸改掉了一些陋習，與世界接軌。觀點2：這是一種文化侵略。西方文化的進入，使中國傳統(tǒng)文化一步步淪喪，特別是我們過著西方圣誕節(jié)時，中國的傳統(tǒng)節(jié)日端午節(jié)已被韓國申報為非物質文化遺產。這告訴我們，我們應該保護我們的傳統(tǒng)文化。面對東西方文化的交匯、碰撞，你認為該怎樣正確看待外來文化和傳統(tǒng)文化？請寫篇小論文闡述你的觀點。2、設計以下表格：利用搜集的資料按照“衣、食、住、行、風俗”五部分進行比較，再將現代社會物質生活和習俗細分為“辛亥革命前和辛亥革命后”兩部分內容進行比較。

人教版高中英語必修4A taste of English Humor說課稿3篇
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

感受生活中的法律 說課稿
一、教材分析《感受生活中的法律》是統(tǒng)編教材小學《道德與法治》六年級上冊第一單元第1課，共有三個話題，本節(jié)課學習的是第一個話題《法律是什么》，主要是引導學生初步了解法律的概念，旨在引導學生通過身邊熟悉的日常生活，感受法律無處不在。二、學情分析六年級的學生在五年的學習中，已經了解了《義務教育法》、《未成年人保護法》等法律，知道生活中有很多規(guī)范我們要遵守，生活中我們有權利，也有義務，但對于法律是什么還都不了解。因此，要通過有效的教學，幫助引導學生通過身邊熟悉的日常生活，了解法律的概念。三、教學目標與重難點基于教材、學情的分析，以及對小學道德與法治課程的理解，我確定了本節(jié)課的教學目標與重難點。教學目標我確定了三個。1.感受日常生活與法律息息相關。2.了解法律規(guī)定了人們的權利與義務。3. 認識以法律為代表的社會規(guī)則。教學重點是：了解法律是什么。難點是：引導學生理解紀律、道德與法律的關系。

師：分析得非常到位。大家來看看薛寶釵是怎么說的？薛寶釵的評論：“不像吟月了，月字底下放一個‘色’字倒還使得，你看句句倒是月色。這也罷了，原來詩從胡說來，再遲幾天就好了。”生：（讀第三首詩）“精華欲掩料應難，影自娟娟魄自寒。一片砧敲千里白，半輪雞唱五更殘。綠蓑江上秋聞笛，紅袖樓頭夜倚欄。博得嫦娥應借問，緣何不使永團圓！”這首詩語言很樸實，但意境很深遠。我雖然讀過《紅樓夢》這本書，也看過電視劇，但我閱歷太淺，說不出詩中所包含的深刻內涵。師：賈寶玉的評論：“這首不但好，而且新巧有意趣，可知俗語說的‘天下無難事，只怕有心人。2．意識的形式是主觀的意識是人腦對客觀存在的反映，意識是不是僅僅是人腦對客觀存在原原本本的反映呢？“龍、鳳”是中華民族的象征，是炎黃子孫的兩大主要圖騰，但地球上從來就沒有出現過“龍、鳳”，那么“龍、鳳”的觀念又是從何而來的呢？原來，“龍、鳳”的觀念最早產生于原始社會的圖騰崇拜。、

1、課題引入：我設計以提問哲學到底是什么？的問題激發(fā)學生的閱讀興趣。我設計典型事例，通過學生討論，教師總結的形式，并得出其實哲學就在我們身邊。2、講授新課：（35分鐘）通過教材第一目的講解，讓學生明白，生活和學習中有許多蘊涵哲學道理的故事，表明哲學并不神秘總結并過渡：生活也離不開哲學，哲學可以是我正確看待自然、人生、和社會的發(fā)展，從而指導人們正確的認識和改造世界。整個過程將伴隨著多媒體影像資料和生生對話討論以提高學生的積極性。3、課堂反饋，知識遷移。最后對本科課進行小結，鞏固重點難點，將本課的哲學知識遷移到與生活相關的例子，實現對知識的升華以及學生的再次創(chuàng)新；可使學生更深刻地理解重點和難點，為下一框學習做好準備。

為了加強學生的理解，讓學生討論以下問題。由師生共同總結。播放一個短時視頻，讓學生認識到水的重要性后，展示節(jié)水標識，說明由來。細胞中的無機鹽這部分，我將展示圖表，并列出問題：表中哪些成分屬于無機鹽？為什么要在運動員喝的飲料中添加無機鹽？無機鹽在細胞的生活中起什么作用？然后展示廣告語，讓學生思考和討論以下問題，并得到答案。再閱讀課本，驗證自己的答案是否正確。關于無機鹽的作用較難理解，通過列舉人體生活與健康中的各種實例來加深感性認識，加強對理論知識的理解3、課堂小結，強化認識。（3—5分鐘）課堂小結，可以把課堂傳授的知識盡快地轉化為學生的素質；簡單扼要的課堂小結，可使學生更深刻地理解理論知識在實際生活中的應用，并且逐漸地培養(yǎng)學生具有良好的個性。4、板書設計我比較注重直觀、系統(tǒng)的板書設計，還及時地體現教材中的知識點，以便于學生能夠理解掌握。5、布置作業(yè)。
