Listening and Speaking introduces the topic of “ask about online habits”. Many middle school students have been surfing the Internet for many years, but what they do with the Internet and how much time they spend every day may not be very clear to themselves, nor to other students. This section allows students to investigate their peers' Internet use, which is conducive to their mutual understanding and understanding of the Internet. It can also help them reflect on their own online behavior, learn from other people's good online habits, and get rid of their bad online behavior.The listening text of this section is an investigation interview. The investigators interview specific groups with the same questions to obtain information, so as to understand their views, practices or attitudes on this issue. There are two specific questions: “how much time do you spend online every day? What do you usually do online?”. The answers of the three respondents provide rich and different information, and achieve the purpose of the investigators. The oral discourse structure of survey interviews generally includes greeting and explaining the purpose of the interview, presenting the interview questions and the respondents' answers. Listening and Talking introduces the theme of “choosing the right application ". Listening text is a conversation between Laura and Xiao Bo. In this part of listening, “oink”; “piggy bank” may cause the students' hearing comprehension limitation. Oink refers to sound word and pig's sound. So, add some oink to my piggy bank is often used to describe "making a little money".1. Guide students to understand the content of listening texts in terms of listening for definitions.2. Cultivate students' ability to define words and understand an investigation interview.

1.用CAI課件模擬汽車的啟動過程。師生共同討論:①如果作用在物體上的力為恒力,且物體以勻速運動,則力對物體做功的功率保持不變。此情況下,任意一段時間內的平均功率與任一瞬時的瞬時功率都是相同的。②很多動力機器通常有一個額定功率,且通常使其在額定功率狀態(tài)工作(如汽車),根據P=FV可知:當路面阻力較小時,牽引力也小,速度大,即汽車可以跑得快些;當路面阻力較大,或爬坡時,需要比較大的牽引力,速度必須小。這就是爬坡時汽車換低速擋的道理。③如果動力機器在實際功率小于額定功率的條件下工作,例如汽車剛剛起動后的一段時間內,速度逐漸增大過程中,牽引力仍可增大,即F和v可以同時增大,但是這一情況應以二者乘積等于額定功率為限度,即當實際功率大于額定功率以后,這種情況不可能實現。
(五)平拋運動規(guī)律的應用例1:一架老式飛機在高出海面45m的高處,以80m/s的速度水平飛行,為了使飛機上投下的炸彈落在停在海面上的敵船,應該在與轟炸目標的水平距離為多遠的地方投彈?不計空氣阻力。分析:對于這道題我們可以從以下幾個方面來考慮:(1)從水平飛行的飛機上投下的炸彈,做什么運動?為什么?(2)炸彈的這種運動可分解為哪兩個什么樣的分運動?3)要想使炸彈投到指定的目標處,你認為炸彈落地前在水平方向通過的距離與投彈時飛機離目標的水平距離之間有什么關系?拓展:1、式飛機在高出海面45m的高處,以80m/s的速度水平飛行,尾追一艘以15m/s逃逸的敵船,為了使飛機上投下的炸彈正好擊中敵船,應該在與轟炸目標的水平距離為多遠的地方投彈?不計空氣阻力。2、在一次摩托車跨越壕溝的表演中,摩托車從壕溝的一側以速度v=40m/s沿水平方向向另一側,壕溝兩側的高度及寬度如圖所示,摩托車可看做質點,不計空氣阻力。(1)判斷摩托車能否跨越壕溝?請計算說明(2)若能跨過,求落地速度?
3.進一步體會力是產生加速度的原因,并通過牛頓第二定律來理解勻速圓周運動、變速圓周運動及一般曲線運動的各自特點。(三)、情感、態(tài)度與價值觀1.在實驗中,培養(yǎng)學生動手、探究的習慣。2.體會實驗的意義,感受成功的快樂,激發(fā)學生探究問題的熱情、樂于學習的品質。教學重點1.體會牛頓第二定律在向心力上的應用。2.明確向心力的意義、作用、公式及其變形,并經行計算。教學難點1.對向心力的理解及來源的尋找。2.運用向心力、向心加速度的知識解決圓周運動問題。教學過程(一)、 引入新課:復習提問:勻速圓周運動的物體的加速度——向心加速度,它的方向和大小有何特點呢?學生回答后進一步引導:那做勻速圓周運動物體的受力有什么特點呢?是什么力使物體做圓周運動而不沿直線飛出?請同學們先閱讀教材
一般情況下,凡是支持物對物體的支持力,都是支持物因發(fā)生形變而對物體產生彈力。所以支持力的方向總是垂直于支持面而指向被支持的物體。例1:放在水平桌面上的書書由于重力的作用而壓迫桌面,使書和桌面同時發(fā)生微小形變,要恢復原狀,對桌面產生垂直于桌面向下的彈力f1,這就是書對桌面的壓力;桌面由于發(fā)生微小的形變,對書產生垂直于書面向上的彈力f2,這就是桌面對書的支持力。學生分析:靜止地放在傾斜木板上的書,書對木板的壓力和木板對書的支持力。并畫出力的示意圖。結論:壓力、支持力都是彈力。壓力的方向總是垂直于支持面而指向被壓的物體,支持力的方向總是垂直于支持面而指向被支持的物體。引導學生分析靜止時,懸繩對重物的拉力及方向。引導得出:懸掛物由于重力的作用而拉緊懸繩,使重物、懸繩同時發(fā)生微小的形變。重物由于發(fā)生微小的形變,對懸繩產生豎直向下的彈力f1,這是物對繩的拉力;懸繩由于發(fā)生微小形變,對物產生豎直向上的彈力f2,這就是繩對物體的拉力。
一、教材內容經全國中小學教材審定委員會2004年初審查通過,人教育出版社出版的普通高中課程標準實驗教科書《物理必修①》,第三章第5節(jié)內容“力的分解”。二、教學目標1.知識與技能(1)理解分力的概念,理解力的分解是力的合成的逆運算,遵循平行四邊形定則。(2)初步掌握一般情況下力的分解要根據實際需要來確定分力的方向。(3)會用作圖法和直角三角形的知識求分力。(4)能區(qū)別矢量和標量,知道三角形定則,了解三角形定則與平行四邊形定則的實質是一樣的。2.過程與方法(1)進一步領會“等效替代”的思想方法。(2)通過探究嘗試發(fā)現問題、探索問題、解決問題能力。(3)掌握應用數學知識解決物理問題的能力。3.情感態(tài)度與價值觀(1)通過猜測與探究享受成功的快樂。(2)感受物理就在身邊,有將物理知識應用于生活和生產實驗的意識。三、教學重點、難點在具體問題中如何根據力的實際作用效果和平行四邊形定則進行力的分解。
l.知識與技能:(1)知道摩擦力產生的條件。(2)能在簡單問題中,根據物體的運動狀態(tài),判斷靜摩擦力的有無、大小和方向;知道存在著最大靜摩擦力。(3)掌握動磨擦因數,會在具體問題中計算滑動磨擦力,掌握判定摩擦力方向的方法。(4)知道影響到摩擦因數的因素。2.過程與方法:通過觀察演示實驗,概括出摩擦力產生的條件及摩擦力的特點,培養(yǎng)學生的觀察、概括能力。通過靜摩擦力與滑動摩擦力的區(qū)別對比,培養(yǎng)學生分析綜合能力。3.情感態(tài)度價值觀:在分析物體所受摩擦力時,突出主要矛盾,忽略次要因素及無關因素,總結出摩擦力產生的條件和規(guī)律。二、重點、難點分析1.本節(jié)課的內容分滑動摩擦力和靜摩擦力兩部分。重點是摩擦力產生的條件、特性和規(guī)律,通過演示實驗得出關系f=μN。2.難點是學生有初中的知識,往往誤認為壓力N的大小總是跟滑動物體所受的重力相等,因此必須指出只有當兩物體的接觸面垂直,物體在水平拉力作用下,沿水平面滑動時,壓力N的大小才跟物體所受的重力相等。
3、課堂小結,強化認識。(2—3分鐘)通過總結本課的知識,簡單的用三個概念三個關系,簡明扼要的總結出本節(jié)課的知識,突出本框題的重難點。其中重點給學生梳理一下哲學的含義,使學生在學習的最后對于哲學有一個全面而準確的理解,強化學生對于哲學的認識。4、課堂練習針對高中學生初步接觸哲學,運用哲學思維來分析哲學問題的能力還需要今后的培養(yǎng),我進行了分層的方式來設計習題,這樣設計一方面符合學生認知的能力,由簡單到困難,一步步的深入,另一方面,在練習的過程中,也可以使學生鞏固基礎知識,使學有余力的學生繼續(xù)提高,充分考慮到學生的實際情況。5、板書設計為了強化教學效果,我會在授課的過程中適時的書寫板書,我的板書設計總的來說是以簡潔明了的形式展示,便于學生一目了然的把握本節(jié)課的重難點,也可以建立知識間的聯系,便于學生形成完整的知識體系。
一、教材分析1、本框題在教材中的地位。本框題教材所處的地位及聯系:《關于世界觀的學說》是人教版2004年12月第一版教材高二政治必修4第一單元第二框題,在這之前學生已經學習了生活處處有哲學的內容,了解了哲學與我們的生活息息相關,這為過度到本框題的學習起到了鋪墊的作用。本框題又是學生進入哲學的入門,因而它在生活與哲學中具有不容忽視的重要地位。學好本框題,為學生從總體上對哲學的理解,為以后學好哲學做了良好的鋪墊作用。本框題是進入哲學與生活不可缺少的部分,也學生的學習生活常常遇到的問題。2、教學目標:1. 知識目標:(1)哲學的含義;(2)哲學與世界觀的關系;(3)哲學與具體科學知識的關系。2. 能力目標:(1)通過對哲學與世界觀、方法論、具體知識三對關系的分析,培養(yǎng)辯證思維的能;(2)通過對身邊生活事例、哲理故事、哲學家觀點的體悟,培養(yǎng)分析問題的能力;
讀《環(huán)境污染組圖》思考:造成交通擁擠的原因是什么?有什么危害?(原因:汽車的增加、汽車數量與道路狀況的比值越來越大造成的。危害:交通阻塞,導致時間和能源的嚴重浪費,影響城市環(huán)境質量。)3.增加就業(yè)困難,失業(yè)人數增多思考:產生這個問題的原因是什么?(隨著城市化發(fā)展,城市科學技術提高,機器化大生產使勞動者數量要求降低,城市人口本來就未充分就業(yè),再加上鄉(xiāng)村人口大量涌入,導致失業(yè)人數增多。)二、解決辦法:(以上海市為例,講解解決的辦法。)1.改善城市環(huán)境:治理河流、控制大氣污染物、大力加強綠化建設為改善城市環(huán)境,上海市全面展開對大氣、河流、噪聲等多方面的治理工作。如蘇州河的治理、降低城市污染物濃度、加強綠化建設,截止1990年,市區(qū)綠化覆蓋率達到20.3%。
