(一)教材的地位與作用本節(jié)主要闡述太陽輻射和太陽活動(dòng)對(duì)地球的影響。太陽輻射對(duì)地球的影響主要是從太陽為地球提供能量這個(gè)方面來闡述,通過圖片的形式從四個(gè)方面來分析。不應(yīng)讓學(xué)生記憶這四個(gè)方面,需要?dú)w納為:(1)直接或間接(化石燃料)為地球提供大部分能量。(2)維持四大圈層物質(zhì)循環(huán)和能量交換,決定地理環(huán)境的基本特征。(二)教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo):1.闡述太陽對(duì)地球的影響。太陽對(duì)地球的影響,包括太陽輻射對(duì)地球的影響和太陽活動(dòng)對(duì)地球的影響。2.太陽輻射的概念、來源、波長等只作一般了解;太陽活動(dòng)對(duì)地球影像是通過作用氣候、地球電離層和磁場(chǎng)而發(fā)生的,主要包括磁暴、無線電短波通訊被干擾、極光和氣候異常等。3.教材涉及太陽活動(dòng)的概念、標(biāo)志和周期需要明確,而太陽大氣分層及對(duì)應(yīng)太陽活動(dòng)現(xiàn)象只作一般了解。

(一)教材的地位與作用該節(jié)教材以水資源作為案例,說明在不同的生產(chǎn)力條件下,水資源的數(shù)量和質(zhì)量對(duì)人類生存和發(fā)展的意義。教材首先從水資源的概念入手,介紹世界和我國的水資源的狀況,接著辨證論述水資源與人類社會(huì)之間的相互影響,緊扣水資源的數(shù)量和質(zhì)量隨時(shí)空變換,對(duì)人類生存與發(fā)展的影響,科技對(duì)水資源的利用也發(fā)揮了一定作用,但是隨著人口持續(xù)增長、經(jīng)濟(jì)高速發(fā)展,不能從根本上解決水資源的短缺,因此必須要從開源和節(jié)流兩方面合理利用水資源。此部分內(nèi)容穿插圖片和實(shí)例,特別是通過以色列水資源的利用和咸海面積縮小的兩個(gè)案例,讓學(xué)生明確和鞏固以上觀點(diǎn)。(二)教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo):1.通過讀圖分析數(shù)據(jù)明了水資源的概念。2.結(jié)合事例了解水資源對(duì)人類發(fā)展的意義。3.通過分析圖表資料認(rèn)識(shí)全球和我國的水資源狀況,提高讀圖分析能力。4.以我國為例,針對(duì)我國的水資源利用狀況,結(jié)合所學(xué),學(xué)生合作探究我國水資源合理利用方案,進(jìn)而歸納基本的水資源可持續(xù)利用策略和措施。

為使學(xué)生對(duì)知識(shí)達(dá)到深化理解、鞏固提高的效果,我結(jié)合兩個(gè)討論題專門設(shè)計(jì)了一組即時(shí)訓(xùn)練題,做完后,屏幕展示匯總,以及時(shí)鞏固新知。然后,進(jìn)行當(dāng)堂訓(xùn)練,這部分習(xí)題分AB兩個(gè)層次,適合不同能力的學(xué)生做,做完后收上,課后批改后會(huì)了解學(xué)生掌握的情況,從而得到準(zhǔn)確的學(xué)習(xí)信息。這部分用時(shí)約6分鐘。三)結(jié)課組織學(xué)生總結(jié)本節(jié)課。引導(dǎo)學(xué)生可對(duì)照教學(xué)目標(biāo)總結(jié)知識(shí),從而盡快將知識(shí)形成能力;也可總結(jié)方法,從而理解生物學(xué)分析思路;還可以談?wù)劯邢?,從而理解人與自然的和諧相處的必要性。最后要求學(xué)生完成課后習(xí)題,課后時(shí)間允許的話還可組織有興趣的同學(xué)進(jìn)行對(duì)當(dāng)?shù)剞r(nóng)田生態(tài)系統(tǒng)的能量流動(dòng)情況得調(diào)查。這部分用時(shí)大約4分鐘。七說板書設(shè)計(jì)生態(tài)系統(tǒng)的能量流動(dòng)一概念:生態(tài)系統(tǒng)中能量的輸入,傳遞和散失過程

本節(jié)課是新版教材人教A版普通高中課程標(biāo)準(zhǔn)實(shí)驗(yàn)教科書數(shù)學(xué)必修1第四章第4.3.2節(jié)《對(duì)數(shù)的運(yùn)算》。其核心是弄清楚對(duì)數(shù)的定義,掌握對(duì)數(shù)的運(yùn)算性質(zhì),理解它的關(guān)鍵就是通過實(shí)例使學(xué)生認(rèn)識(shí)對(duì)數(shù)式與指數(shù)式的關(guān)系,分析得出對(duì)數(shù)的概念及對(duì)數(shù)式與指數(shù)式的 互化,通過實(shí)例推導(dǎo)對(duì)數(shù)的運(yùn)算性質(zhì)。由于它還與后續(xù)很多內(nèi)容,比如對(duì)數(shù)函數(shù)及其性質(zhì),這也是高考必考內(nèi)容之一,所以在本學(xué)科有著很重要的地位。解決重點(diǎn)的關(guān)鍵是抓住對(duì)數(shù)的概念、并讓學(xué)生掌握對(duì)數(shù)式與指數(shù)式的互化;通過實(shí)例推導(dǎo)對(duì)數(shù)的運(yùn)算性質(zhì),讓學(xué)生準(zhǔn)確地運(yùn)用對(duì)數(shù)運(yùn)算性質(zhì)進(jìn)行運(yùn)算,學(xué)會(huì)運(yùn)用換底公式。培養(yǎng)學(xué)生數(shù)學(xué)運(yùn)算、數(shù)學(xué)抽象、邏輯推理和數(shù)學(xué)建模的核心素養(yǎng)。1、理解對(duì)數(shù)的概念,能進(jìn)行指數(shù)式與對(duì)數(shù)式的互化;2、了解常用對(duì)數(shù)與自然對(duì)數(shù)的意義,理解對(duì)數(shù)恒等式并能運(yùn)用于有關(guān)對(duì)數(shù)計(jì)算。

一、教學(xué)理念在新課改精神指導(dǎo)下,我在本課教學(xué)中力求貫徹以下教學(xué)理念:新課標(biāo)的指引觀 、生本位的學(xué)生觀、探究式的學(xué)習(xí)觀、多角色的教師觀、 發(fā)展性的評(píng)價(jià)觀二、教材地位《馬克思主義的誕生》是人教版必修一第五單元第18課內(nèi)容,本課講述的是國際共產(chǎn)主義運(yùn)動(dòng)范疇的歷史,是人類社會(huì)進(jìn)入一個(gè)新的發(fā)展時(shí)期。從總體上概述了社會(huì)主義從空想到科學(xué),從理論到實(shí)踐的歷程。說明了科學(xué)社會(huì)主義理論是歷史發(fā)展的必然結(jié)果。本課在國際工運(yùn)史上占有重要的地位。通過學(xué)習(xí)學(xué)生可對(duì)馬克思主義加深了解,理解人類歷史發(fā)展的必然趨勢(shì)以及人類一直不斷追求進(jìn)步的精神,幫助學(xué)生樹立正確的人生觀、價(jià)值觀,達(dá)到以史鑒今,服務(wù)現(xiàn)實(shí)的目的。

二、學(xué)情分析:學(xué)生目前對(duì)形變和彈力有一定的感性認(rèn)識(shí)但是不夠深入;知道支持力、壓力都是彈力,但是不能夠概括產(chǎn)生的原因。理性思維還沒有達(dá)到一定的層次,要想理解彈力這一抽象概念還有一定困難。因此我采取引導(dǎo)、啟發(fā)的教學(xué)方式。

一、說活動(dòng)背景(幻燈片)在新中國成立70周年之際,中華人民共和國國家勛章和國家榮譽(yù)稱號(hào)頒受儀式29日在京舉行。今天,我們要敬仰英雄、學(xué)習(xí)英雄、忠誠擔(dān)當(dāng),為實(shí)現(xiàn)中華民族偉大復(fù)興的中國夢(mèng)貢獻(xiàn)力量?,F(xiàn)在的孩子,物質(zhì)生活極為優(yōu)越,但在他們心中只有“小我”,而無“大志”。在這樣的背景下,對(duì)學(xué)生進(jìn)行正確價(jià)值觀、人生觀的思想教育顯得十分必要。因此,特設(shè)計(jì)本節(jié)隊(duì)課。二、說設(shè)計(jì)理念(幻燈片)主要培養(yǎng)隊(duì)員“愛祖國,擔(dān)責(zé)任,立大志,圓夢(mèng)想”的思想,并使做中華有志少年的種子融入隊(duì)員的理想之中。說活動(dòng)目標(biāo)和前期準(zhǔn)備本節(jié)課的活動(dòng)目標(biāo)是:1.引導(dǎo)隊(duì)員了解英雄的事例和“時(shí)代精神”的真正內(nèi)涵。2.通過本次少先隊(duì)活動(dòng)課幫助隊(duì)員樹立正確的價(jià)值觀,做新時(shí)代中華民族有志少年。

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.

The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

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.
