人教版高中地理必修2南京的自行車是多了還是少了說課稿
在學生回答的基礎(chǔ)上進行歸納小結(jié)：發(fā)展城市公共交通? 明確道路分工? 合理規(guī)劃停車場? 減少出行距離? 錯開出行高峰? 加大城市道路建設(shè)? 進行科學合理的交通管理，重視智能交通系統(tǒng)的建設(shè)提問：這組同學在幻燈片中提到城市環(huán)境污染源主要有哪些？城市交通環(huán)境問題除了交通工具的尾氣排放帶來大氣污染外，還會給城市環(huán)境帶來什么問題？這組同學基本同意自行車多是加劇南京空氣污染的間接原因，你同意他們的觀點嗎？在學生回答的基礎(chǔ)上，教師進行歸納小結(jié)：自行車是一種綠色交通工具，既環(huán)保又經(jīng)濟。只有當它在某些機動車和非機動車不分的地段，影響車輛行駛速度的時候，它才可能成為加劇空氣污染的間接原因。那么我們針對交通工具對環(huán)境造成的影響，除了這組同學提到的三點解決措施以外，我們還有什么要補充的解決方法嗎？

（三）反饋練習（5分鐘）1、伽利略研究速度與時間的關(guān)系時遇到那些困難？他是怎樣巧妙解決的？2、給出5分鐘讓學生閱讀課后的閱讀材料，體會伽利略一生中對科學和社會的重大貢獻。（四）課堂小結(jié)：教師將本節(jié)的學習目標投影到大屏幕上，和學生一起簡單的總結(jié)。（五）課后作業(yè)1、利用現(xiàn)代的測量儀器設(shè)計出一個研究自由落體運動規(guī)律的實驗，寫出需要的器材和實驗過程。2、請學生再總結(jié)出一些科學研究中常用的思路和方法。通過這兩個作業(yè)，進一步提高學生的科學研究的意識和素質(zhì)。本設(shè)計所涉及到的科學研究方法：1、歸繆法——伽利略用亞里士多德的觀點推翻了翻亞里士多德的觀點。2、轉(zhuǎn)換法——伽利略用數(shù)學推理和斜面實驗間接證明他的假設(shè)。3、邏輯推理法——用數(shù)學方法推理出速度正比于時間則位移與時間二次方成正比。4、外推法——由斜面實驗外推至自由落體運動運動規(guī)律
人教版新課標高中物理必修2探究彈性勢能的表達式說課稿4篇
設(shè)疑自探：一個壓縮或拉伸的彈簧就是一個“儲能器”，怎樣衡量形變彈簧蘊含能量的多少呢？彈簧的彈性勢能的表達式可能與那幾個物理量有關(guān)？類比：物體的重力勢能與物體所受的重力和高度有關(guān)。那么彈簧的彈性勢能可能與所受彈力的大小和在彈力方向上的位置變化有關(guān)，而由F=kl知彈簧所受彈力等于彈簧的勁度系數(shù)與形變量的乘積。預測：彈簧的彈性勢能與彈簧的勁度系數(shù)和形變量有關(guān)。學生討論如何設(shè)計實驗： ①、用同一根彈簧在幾次被壓縮量不同時釋放（勁度系數(shù)相同，改變形變量），觀察小車被彈開的情況。②、分別用兩根彈簧在被壓縮量相同時釋放（形變量相同，勁度系數(shù)不同），觀察小車被彈開的情況。交流探究結(jié)果：彈性勢能隨彈簧形變量增大而增大。隨彈簧的勁度系數(shù)的增大而增大。

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.
