3、若出現(xiàn)了個別明顯偏離絕大部分點所在直線的點，該如何處理？（對于個別明顯偏離絕大部分點所在直線的點，我們可以認(rèn)為是測量誤差過大、是測量中出現(xiàn)差錯所致，將它視為無效點，但是在圖像當(dāng)中仍應(yīng)該保留，因為我們要尊重實驗事實，這畢竟是我們的第一手資料，是原始數(shù)據(jù)。）4、怎樣根據(jù)所畫的v－t圖像求加速度？(從所畫的圖像中取兩個點，找到它們的縱、橫坐標(biāo)（t1，v1）、（t2，v2），然后代入公式，求得加速度，也就是直線的斜率。在平面直角坐標(biāo)系中，直線的斜率四、實踐與拓展例1、在探究小車速度隨時間變化規(guī)律的實驗中，得到一條記錄小車運動情況的紙帶，如圖所示。圖中A、B、C、D、E為相鄰的計數(shù)點，相鄰計數(shù)點的時間間隔為T＝0.1s。⑴根據(jù)紙帶上的數(shù)據(jù)，計算B、C、D各點的數(shù)據(jù)，填入表中。

一、設(shè)計思想通過本節(jié)教學(xué)，不但要使學(xué)生認(rèn)識掌握勻變速直線運動的規(guī)律，而且要通過對這問題的研究，使學(xué)生了解和體會物理學(xué)研究問題的一個方法，圖象、公式、以及處理實驗數(shù)據(jù)的方法等。這一點可能對學(xué)生更為重要，要通過學(xué)習(xí)過程使學(xué)生有所體會。本節(jié)在內(nèi)容的安排順序上，既注意了科學(xué)系統(tǒng)，又注意學(xué)生的認(rèn)識規(guī)律。講解問題從實際出發(fā)，盡量用上一節(jié)的實驗測量數(shù)據(jù)。運用圖象這種數(shù)學(xué)工具，相對強調(diào)了圖象的作用和要求。這是與以前教材不同的。在現(xiàn)代生產(chǎn)、生活中，圖象的運用隨處可見，無論學(xué)生將來從事何種工作，掌握最基本的應(yīng)用圖象的知識，都是必須的。學(xué)生在初學(xué)時往往將數(shù)學(xué)和物理分割開來，不習(xí)慣或不會將已學(xué)過的數(shù)學(xué)工具用于物理當(dāng)中。在教學(xué)中應(yīng)多在這方面引導(dǎo)學(xué)生。本節(jié)就是一個較好的機會，將圖象及其物理意義聯(lián)系起來。

人教版新課標(biāo)高中物理必修1速度變化快慢的描述─加速度教案2篇
【設(shè)計思路】新課程十分強調(diào)科學(xué)探究在科學(xué)課程中的作用,應(yīng)該說科學(xué)探究是這次課程改革的核心。我覺得：科學(xué)探究不一定是要讓學(xué)生純粹地通過實驗進行探究，應(yīng)該說科學(xué)探究是一種科學(xué)精神,學(xué)生只要通過自己的探索和體驗,變未知為已知,這樣的教學(xué)活動也是科學(xué)探究。本節(jié)課是概念教學(xué)課,讓學(xué)生純粹地通過實驗進行探究是不太合適的。但通過學(xué)生自己的探索和體驗,變未知為已知還比較合適。本節(jié)課的設(shè)計就是基于這樣的出發(fā)點,在引出加速度的概念時低臺階,步步深入,充分激活學(xué)生的思維,是學(xué)生思維上的探究。通過復(fù)習(xí)前邊速度時間圖像，從而得到從圖像上得到加速度的方法，為加深加速度概念和相關(guān)知識的理解有配套了相應(yīng)練習(xí)題目，做到強化練習(xí)的目的。【教學(xué)目標(biāo)】知識與技能1．理解加速度的意義，知道加速度是表示速度變化快慢的物理量．知道它的定義、公式、符號和單位，能用公式a=△v/△t進行定量計算．2．知道加速度與速度的區(qū)別和聯(lián)系，會根據(jù)加速度與速度的方向關(guān)系判斷物體是加速運動還是減速運動．

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.

人教版高中歷史必修1甲午中日戰(zhàn)爭說課稿
3．甲午中日戰(zhàn)爭中國戰(zhàn)敗的原因 對于“中國戰(zhàn)敗的原因”這一難點的突破，主要通過設(shè)置問題“中國之?dāng)≡趯嵙d于日本嗎？”通過幻燈片全方位分析其實中國的綜合國力當(dāng)時是強于日本的。并且在戰(zhàn)前，日本毫無取勝的把握。讓學(xué)生結(jié)合剛學(xué)習(xí)過的戰(zhàn)爭原因和經(jīng)過進行討論，從多方面分析中國戰(zhàn)敗的原因。經(jīng)過討論，學(xué)生可以得出以下結(jié)論：避戰(zhàn)自保方針，沒有積極備戰(zhàn)，將領(lǐng)臨陣脫逃，教師肯定并總結(jié)答案進行補充。中日對比：中國士兵出身農(nóng)民，軍事訓(xùn)練落后，散兵游勇；日本士兵出身武士，訓(xùn)練有素；中國將領(lǐng)大多臨陣脫逃，并相互猜忌，受當(dāng)時惡劣的官風(fēng)影響；李鴻章深知北洋海軍實情，缺乏軍費，軍備廢弛。為政治資本奉行避戰(zhàn)自保政策，慈禧太后挪用海軍軍費過壽，支持李鴻章。使中方處于被動的局面，一再貽誤戰(zhàn)機。而日本在天皇的帶動下，全民備戰(zhàn)，做了充分的戰(zhàn)爭準(zhǔn)備。

為了加強學(xué)生的理解，讓學(xué)生討論以下問題。由師生共同總結(jié)。播放一個短時視頻，讓學(xué)生認(rèn)識到水的重要性后，展示節(jié)水標(biāo)識，說明由來。細(xì)胞中的無機鹽這部分，我將展示圖表，并列出問題：表中哪些成分屬于無機鹽？為什么要在運動員喝的飲料中添加無機鹽？無機鹽在細(xì)胞的生活中起什么作用？然后展示廣告語，讓學(xué)生思考和討論以下問題，并得到答案。再閱讀課本，驗證自己的答案是否正確。關(guān)于無機鹽的作用較難理解，通過列舉人體生活與健康中的各種實例來加深感性認(rèn)識，加強對理論知識的理解3、課堂小結(jié)，強化認(rèn)識。（3—5分鐘）課堂小結(jié)，可以把課堂傳授的知識盡快地轉(zhuǎn)化為學(xué)生的素質(zhì)；簡單扼要的課堂小結(jié)，可使學(xué)生更深刻地理解理論知識在實際生活中的應(yīng)用，并且逐漸地培養(yǎng)學(xué)生具有良好的個性。4、板書設(shè)計我比較注重直觀、系統(tǒng)的板書設(shè)計，還及時地體現(xiàn)教材中的知識點，以便于學(xué)生能夠理解掌握。5、布置作業(yè)。
