一、教材分析(一)說本框題的地位與作用《樹立創(chuàng)新意識是唯物辯證法的要求》是人教版教材高二《生活與哲學(xué)》第三單元第十課的第一框題,該部分的內(nèi)容實(shí)質(zhì)上是在闡述辯證法的革命批判精神和否定之否定規(guī)律。是第三單元思想方法與創(chuàng)新意識》的重點(diǎn)和核心之一。學(xué)好這部分的知識對于學(xué)生進(jìn)一步理解辯證法的思維方法,樹立創(chuàng)新意識起著重要的作用。(二)說教學(xué)目標(biāo)根據(jù)課程標(biāo)準(zhǔn)和課改精神,在教學(xué)中確定如下三維目標(biāo):1、知識目標(biāo):辯證否定觀的內(nèi)涵,辯證法的本質(zhì)。辯證否定是自我否定,辯證否定觀與書本知識和權(quán)威思想的關(guān)系,辯證法的革命批判精神與創(chuàng)新意識的關(guān)系,分析辯證否定的實(shí)質(zhì)是"揚(yáng)棄",是既肯定又否定;既克服又保留。深刻理解辯證法的革命批判精神,分析為什么辯證法的革命批判精神同創(chuàng)新意識息息相關(guān)。
環(huán)節(jié)四 情感升華,感悟生活播放《愛我中華》,感受祖國的偉大,民族的團(tuán)結(jié)。設(shè)計(jì)意圖:使學(xué)生感受偉大的中華民族的精神,內(nèi)心產(chǎn)生共鳴,抒發(fā)強(qiáng)烈的愛國熱情。教師帶領(lǐng)學(xué)生一起合唱,用歌聲結(jié)束本堂課內(nèi)容,能再次喚起學(xué)生的愛國情感,使學(xué)生認(rèn)識到:維護(hù)國家統(tǒng)一和民族團(tuán)結(jié)是每個(gè)公民的義務(wù)。環(huán)節(jié)五 課堂小結(jié) 鞏固知識本節(jié)課我采用線索性的板書,整個(gè)知識結(jié)構(gòu)一目了然,為了充分發(fā)揮學(xué)生在課堂的主體地位,我將課堂小結(jié)交由學(xué)生完成,請學(xué)生根據(jù)課堂學(xué)習(xí)的內(nèi)容,結(jié)合我的板書設(shè)計(jì)來進(jìn)行小結(jié),以此來幫助教師在第一時(shí)間掌握學(xué)生學(xué)習(xí)信息的反饋,同時(shí)培養(yǎng)學(xué)生歸納分析能力、概括能力。本節(jié)課,我根據(jù)建構(gòu)主義理論,強(qiáng)調(diào)學(xué)生是學(xué)習(xí)的中心,學(xué)生是知識意義的主動(dòng)建構(gòu)者,是信息加工的主體,要強(qiáng)調(diào)學(xué)生在課堂中的參與性、以及探究性,不僅讓他們懂得知識,更讓他們相信知識,并且將知識融入到實(shí)踐當(dāng)中去,最終達(dá)到知、情、意、行的統(tǒng)一。
1.直觀圖:表示空間幾何圖形的平面圖形,叫做空間圖形的直觀圖直觀圖往往與立體圖形的真實(shí)形狀不完全相同,直觀圖通常是在平行投影下得到的平面圖形2.給出直觀圖的畫法斜二側(cè)畫法觀察:矩形窗戶在陽光照射下留在地面上的影子是什么形狀?眺望遠(yuǎn)處成塊的農(nóng)田,矩形的農(nóng)田在我們眼里又是什么形狀呢?3. 給出斜二測具體步驟(1)在已知圖形中取互相垂直的X軸Y軸,兩軸相交于O,畫直觀圖時(shí),把他們畫成對應(yīng)的X'軸與Y'軸,兩軸交于O'。且使∠X'O'Y'=45°(或135°)。他們確定的平面表示水平面。(2)已知圖形中平行于X軸或y軸的線段,在直觀圖中分別畫成平行于X'軸或y'軸的線段。(3)已知圖形中平行于X軸的線段,在直觀圖中保持原長度不變,平行于Y軸的線段,在直觀圖中長度為原來一半。4.對斜二測方法進(jìn)行舉例:對于平面多邊形,我們常用斜二測畫法畫出他們的直觀圖。如圖 A'B'C'D'就是利用斜二測畫出的水平放置的正方形ABCD的直觀圖。其中橫向線段A'B'=AB,C'D'=CD;縱向線段A'D'=1/2AD,B'C'=1/2BC;∠D'A'B'=45°,這與我們的直觀觀察是一致的。5.例一:用斜二測畫法畫水平放置的六邊形的直觀圖(1)在六邊形ABCDEF中,取AD所在直線為X軸,對稱軸MN所在直線為Y軸,兩軸交于O',使∠X'oy'=45°(2)以o'為中心,在X'上取A'D'=AD,在y'軸上取M'N'=½MN。以點(diǎn)N為中心,畫B'C'平行于X'軸,并且等于BC;再以M'為中心,畫E'F'平行于X‘軸并且等于EF。 (3)連接A'B',C'D',E'F',F'A',并擦去輔助線x軸y軸,便獲得正六邊形ABCDEF水平放置的直觀圖A'B'C'D'E'F' 6. 平面圖形的斜二測畫法(1)建兩個(gè)坐標(biāo)系,注意斜坐標(biāo)系夾角為45°或135°;(2)與坐標(biāo)軸平行或重合的線段保持平行或重合;(3)水平線段等長,豎直線段減半;(4)整理.簡言之:“橫不變,豎減半,平行、重合不改變?!?/p>

Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

1. 這個(gè)寓言是一個(gè)關(guān)于一位國王古寓言。 The fable is an old fable about a king.2.作者用這個(gè)故事讓讀者對于社區(qū)的問題負(fù)有個(gè)人責(zé)任的必要印象深刻。The author used the story to impress upon readers with the need to take personal responsibility for problems in the community.3. 這個(gè)故事十分成功的實(shí)現(xiàn)了它的目的。The story was quite successful in achieving its purpose.Step 7 WritingPlease write a review of the story according the outline above.The fable is an old fable about a king who thought his people are lazy, so he put a large stone in the middle of the road and hides and waited to see if anyone will try to move it.The author used this story to impress upon readers with the need to take personal responsibility for problems in the community. The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1. Does the writer give a short description of the story ?2. Does the description include the most important details of the story ?3.

In Picture 3, can you find which village it is? What time is it in the picture?It is Dong village. It is at night. Step 2 While-listeningJustin met a new friend while traveling in Guizhou. Listen to their conversation and complete the summaries below.Part 1Justin and Wu Yue watched some Miao people play the lusheng. The instrument has a history of over 3,000 years and it is even mentioned in the oldest collection of Chinese poetry. Then they watched the lusheng dance. Justin wanted to buy some hand-made silver/traditional accessories as souvenirs. He was told that the price will depend on the percentage of silver. Part 2They will go to a pretty Dong minority village called Zhaoxing. they will see the drum towers and the wind and rain bridges. They may also see a performance of the Grand Song of the Dong people.Step 3 Post-listening---TalkingWork in groups. Imagine Justin is telling some friends about his trip to Guizhou. One of you is Justin and the rest of you are his friends. Ask Justin questions about his trip and experience. The following expressions may help you.
Discuss these questions in groups.Q1: Have you ever been to a place that has a diverse culture ? What do you think about the culture diversity ?One culturally diverse place that I have been to is Harbin, the capital city of Heilongjiang Province. I went there last year with my family to see the Ice and Snow Festival, and I was amazed at how the culture as different to most other Chinese cities. There is a big Russian influence there, with beautiful Russian architecture and lots of interesting restaurants. I learnt that Harbin is called “the Oriental Moscow” and that many Russians settled there to help build the railway over 100 years ago.Q2: What are the benefits and challenges of cultural diversity ?The benefits: People are able to experience a wide variety of cultures, making their lives more interesting, and it can deepen the feelings for our national culture, it is also helpful for us to learn about other outstanding culture, which helps improve the ability to respect others.
