The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

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.

教學(xué)重點(diǎn)1．自由落體運(yùn)動的概念及探究自由落體運(yùn)動的過程。2．掌握自由落體運(yùn)動規(guī)律，并能運(yùn)用其解決實際問題。教學(xué)難點(diǎn)演示實驗和探究實驗的技巧及自由落體運(yùn)動規(guī)律的得出.教學(xué)過程設(shè)計思想：1、 先用游戲激發(fā)學(xué)生學(xué)習(xí)興趣，順理成章地研究落體運(yùn)動；2、 通過演示實驗讓學(xué)生自己總結(jié)出物體下落快慢不同的主要原因是空氣阻力，從而猜想若沒有空氣阻力會怎樣；3、 用牛頓管實驗驗證猜想，引入了新的理想運(yùn)動模型：自由落體運(yùn)動。講述1971年宇航員做的實驗，加深印象；4、 了解地球表面物體下落運(yùn)動近似成自由落體運(yùn)動的條件；5、 著手研究自由落體運(yùn)動的規(guī)律，利用打點(diǎn)計時器進(jìn)行研究，得到結(jié)論；6、 總結(jié)自由落體運(yùn)動特點(diǎn)及重力加速度；7、 應(yīng)用訓(xùn)練
人教版新課標(biāo)高中物理必修1牛頓第二定律教案2篇
1．這節(jié)課以實驗為依據(jù)，采用控制變量的方法進(jìn)行研究。這一方法今后在電學(xué)、熱學(xué)的研究中還要用到。我們根據(jù)已掌握的知識設(shè)計實驗、探索規(guī)律是物體研究的重要方法。2．定義力的單位“牛頓”使得k=1，得到牛頓第二定律的簡單形式F=ma。使用簡捷的數(shù)學(xué)語言表達(dá)物理規(guī)律是物理學(xué)的特征之一，但應(yīng)知道它所對應(yīng)的文字內(nèi)容和意義。3．牛頓第二定律概括了運(yùn)動和力的關(guān)系。物體所受合外力恒定，其加速度恒定；合外力為零，加速度為零。即合外力決定了加速度，而加速度影響著物體的運(yùn)動情況。因此，牛頓第二定律是把前兩章力和物體的運(yùn)動構(gòu)成一個整體，其中的紐帶就是加速度。四、評價方案及說明1、對科學(xué)知識與技能的評價要注重科學(xué)內(nèi)容的理解與應(yīng)用，而不是單純記憶。技能的評價目標(biāo)包括觀察技能、實驗技能等方面。對科學(xué)的技能的評價要盡量融合在科學(xué)探究過程的情景中。對科學(xué)知識的評價主要從兩方面，一是根據(jù)學(xué)生診斷性練習(xí)；二是通過學(xué)生作業(yè)反映學(xué)生掌握情況。
人教版新課標(biāo)高中物理必修1伽利略對自由落體運(yùn)動的研究教案2篇
猜想：既然物體下落過程中的運(yùn)動情況與物體質(zhì)量無關(guān)，那么為什么在現(xiàn)實生活中，不同物體的落體運(yùn)動，下落快慢不同呢？我們能否猜想是由于空氣阻力的作用造成的呢？如果沒有空氣阻力將會怎樣呢？學(xué)生討論后回答.三、猜想與假說伽利略認(rèn)為，自由落體是一種最簡單的變速運(yùn)動.他設(shè)想，最簡單的變速運(yùn)動的速度應(yīng)該是均勻變化的.但是，速度的變化怎樣才算均勻呢?他考慮了兩種可能：一種是速度的變化對時間來說是均勻的，即經(jīng)過相等的時間，速度的變化相等；另一種是速度的變化對位移來說是均勻的，即經(jīng)過相等的位移，速度的變化相等.伽利略假設(shè)第一種方式最簡單，并把這種運(yùn)動叫做勻變速運(yùn)動.四、實驗驗證實驗驗證是檢驗理論正確與否的唯一標(biāo)準(zhǔn).任何結(jié)論和猜想都必須經(jīng)過實驗驗證，否則不成理論.猜想或假說只有通過驗證才會成為理論.所謂實驗驗證就是任何人，在理論條件下去操作都能到得實驗結(jié)果，它具有任意性，但不是無條件的，實驗是在一定條件下的驗證，而與實際有區(qū)別.
人教版新課標(biāo)高中物理必修1力學(xué)單位制教案2篇
一、教材分析在初中階段，物理量單位的學(xué)習(xí)是學(xué)生較為困惑的問題之一。前面關(guān)于1N的規(guī)定給學(xué)生的印象總好像是有些隨意。尤其是牛頓、帕斯卡、安培、伏特、焦耳、瓦特等單位的規(guī)定。使得學(xué)生感動物理太復(fù)雜。事實上，只有把單位制放在整個物理學(xué)框架中加以認(rèn)識，并且知識有了一定的積累。經(jīng)歷了充分的學(xué)習(xí)過程后才能體會物理量單位的命名和使用規(guī)則。體會到其中對一些單位進(jìn)行規(guī)定的合理性和方便特征。物理學(xué)單位中，有很少幾個基本物理量，它們的單位就是基本單位。在進(jìn)行了這種選定之后，其它物理量的單位就是根據(jù)它的定義式，有所選擇的其他物理量的單位共同確定的。國際單位制的建立和使用，不僅方便了國際間的交流，也逐漸成為科學(xué)研究中計算和運(yùn)用的一種規(guī)范約束。中學(xué)生應(yīng)該注意學(xué)習(xí)，逐步習(xí)慣，在記錄、表達(dá)和計算中規(guī)范使用。二、教學(xué)目標(biāo)（一）知識與技能1．了解什么是單位制，知道力學(xué)中的三個基本單位；2．認(rèn)識單位制在物理計算中的作用

①平動的物體一般可以看作質(zhì)點(diǎn)做平動的物體，由于物體上各點(diǎn)的運(yùn)動情況相同，可以用一個點(diǎn)代表整個物體的運(yùn)動，在這種情況下，物體的大小、形狀就無關(guān)緊要了，可以把整個物體當(dāng)質(zhì)點(diǎn)。例如：平直公路上行駛的汽車，車身上各部分的運(yùn)動情況相同，當(dāng)我們把汽車作為一個整體來研究它的運(yùn)動的時候，就可以把汽車當(dāng)作質(zhì)點(diǎn)。當(dāng)然，假如我們需要研究汽車輪胎的運(yùn)動，由于輪胎上各部分運(yùn)動情況不相同，那就不能把它看作質(zhì)點(diǎn)了。要注意的是：同一物體在不同情況下有時可看質(zhì)點(diǎn)，有時不可以看作質(zhì)點(diǎn)，一列火車從北京開到上海，研究火車的運(yùn)行的時間，可將火車看成質(zhì)點(diǎn)，而火車過橋時，計算火車過橋的時間，不可以將火車看成質(zhì)點(diǎn)。②有轉(zhuǎn)動但轉(zhuǎn)動為次要因素例如：研究地球公轉(zhuǎn)時，可把地球看作質(zhì)點(diǎn)；研究地球自轉(zhuǎn)時，不能把地球看作質(zhì)點(diǎn)。③物體的形狀、大小可忽略再如：乒乓球旋轉(zhuǎn)對球的運(yùn)動的較大的影響，運(yùn)動員在發(fā)球、擊球時都要考慮，就不能把乒乓球簡單看作質(zhì)點(diǎn)。

（創(chuàng)設(shè)實例：多媒體播放視頻劉翔的110m欄。）1．提出問題：怎樣定量（準(zhǔn)確）人描述車或劉翔所在的位置？2．提示：你的描述必須能反映物體（或人）的運(yùn)動特點(diǎn)（直線）、運(yùn)動方向、各點(diǎn)之間的距離等因素。3．總結(jié)：①為了定量地描述物體的位置及位置的變化，需要在參考系上建立適當(dāng)?shù)淖鴺?biāo)系。坐標(biāo)系是在參考系的基礎(chǔ)上抽象出來的概念，是抽象化的參考系。為了定量地描述物體的位置及位置的變化需要在參考系上建立適當(dāng)?shù)淖鴺?biāo)系，如果物體在一維空間運(yùn)動，即沿一條直線運(yùn)動，只需建立直線坐標(biāo)系，就能準(zhǔn)確表達(dá)物體的位置；如果物體在二維空間運(yùn)動，即在同一平面運(yùn)動，就需要建立平面直角坐標(biāo)系來描述物體的位置；當(dāng)物體在三維空間運(yùn)動時，則需要建立三維坐標(biāo)系。①一維坐標(biāo)：描述物體在一條直線上運(yùn)動，即物體做一維運(yùn)動時，可以以這條直線為x軸，在直線上規(guī)定原點(diǎn)、正方向和單位長度，建立直線坐標(biāo)系。如圖1-1-1所示，若某一物體運(yùn)動到A點(diǎn)，此時它的位置坐標(biāo)XA＝3m，若它運(yùn)動到B點(diǎn)，則此時它的坐標(biāo)XB＝-2m（“-”表示沿X軸負(fù)方向）。
