人教版新課標高中物理必修1探究加速度與力、質量的關系教案2篇
三、制定實驗方案的兩個問題：1．怎樣測量（或比較）物體的加速度：引導學生思考、討論并交流。學生可能會提出下面的一些方案：方法一：測出初速度為零的勻加速直線運動的物體在 時間內的位移 ，則 ；方法二：在運動的物體上安裝一條打點計時器的紙帶，根據紙帶上打出的點來測量加速度；方法三：測出兩個初速度為零的勻加速運動的物體在相同的時間內發(fā)生的位移 、 ，則 ；方法四：測出兩個初速度為零的勻加速運動的物體在相同的位移內所用的時間 、 ，則 ；2．怎樣提供并測量物體所受的恒力：教師提出：現實中，除了在真空中拋出或落下的物體（僅受重力）外，僅受一個力的物體幾乎是不存在的。然而，一個單獨的力作用效果與跟它大小、方向都相同的合力的作用效果是相同的，因此，實驗中力 的含義指物體所受的合力。以在水平軌道上用繩牽引小車加速運動為例，小車受到四個力的作用，即重力、支持力、繩的拉力和軌道對小車的摩擦力（當物體運動的速度比較小時，我們可以忽略空氣的阻力）。

1．加速度與力的關系：實驗的基本思路是保持物體的質量不變，測量物體在不同的力的作用下的加速度，分析加速度與力的關系。有了實驗的基本思路，接下去我們就要準備實驗器材，以及為記錄實驗數據而設計一個表格。為了更直觀地判斷加速度與力的數量關系，我們以 為縱坐標、 為橫坐標建立坐標系，根據各組數據在坐標系中描點。如果這些點在一條過原點的直線上，說明 與 成正比，如果不是這樣，則需進一步分析。2．加速度與質量的關系：實驗的基本思路是保持物體所受力不變，測量不同質量的物體在該力作用下的加速度，分析加速度與質量的關系。有了實驗的基本思路，接下去我們就要準備實驗器材，以及為記錄實驗數據而設計一個表格。為了更直觀地判斷加速度與質量的數量關系，我們以 為縱坐標、 為橫坐標建立坐標系，根據各組數據在坐標系中描點，根據擬合的曲線形狀，初步判斷 與 的關系是反比例函數。再把 圖像改畫為 圖像，如果是一條過原點的斜直線，說明自己的猜測是否正確。
人教版新課標高中物理必修2探究彈性勢能的表達式教案2篇
“做功的過程就是能量轉化過程”，這是本章教學中的一條主線。對于一種勢能，就一定對應于相應的力做功。類比研究重力勢能是從分析重力做功入手的，研究彈簧的彈性勢能則應從彈簧的彈力做功入手。然而彈簧的彈力是一個變力，如何研究變力做功是本節(jié)的一個難點，也是重點。首先，要引導學生通過類比重力做功和重力勢能的關系得出彈簧的彈力做功和彈簧的彈性勢能的關系。其次，通過合理的猜想與假設得出彈簧的彈力做功與哪些物理量有關。最后，類比勻變速直線運動求位移的方法，進行知識遷移，利用微元法的思想得到彈簧彈力做功的表達式，逐步把微分和積分的思想滲透到學生的思維中。本節(jié)課通過游戲引入課題，通過生活中拉弓射箭、撐桿跳高和彈跳蛙等玩具以及各種彈簧等實例來創(chuàng)設情景，提出問題。給學生感性認識，引起學生的好奇心；讓學生對彈簧彈力做功的影響因素進行猜想和假設，提出合理的推測，激發(fā)學生的探索心理，構思實驗，為定性探究打下基礎。然后，引導學生通過類比重力做功與重力勢能的關系得出彈簧彈性勢能與彈簧彈力做功的關系。

說明：“倍增法”是一種重要的物理方法，歷史上庫侖在研究電荷間的相互作用力時曾用過此法，但學生在此前的物理學習中可能未曾遇到類似例子，因此引導學生通過交流，領會“倍增法”的妙處，這是本節(jié)課的一個要點．可用體育鍛煉中的“拉力器”來類比。（2）該方案消除摩擦力影響的方法：所用的消除方法與實驗方案2一樣。也可使用氣墊導軌代替木板，以更好地消除摩擦影響。（3）小車速度的確定方法：①確定打出來的點大致呈現什么規(guī)律：先密后疏（變加速），再均勻分布（勻速）；②應研究小車在哪個時刻的速度：在橡皮筋剛恢復原長時小車的瞬時速度，即紙帶上的點剛開始呈現均勻分布時的速度；③應如何取紙帶上的點距以確定速度：由于實驗器材和每次操作的分散性，尤其是橡皮筋不可能長度、粗細完全一致，使得每次改變橡皮筋的條數后，紙帶上反映小車勻速運動的點數和點的位置，不一定都在事先的設定點（即用一條橡皮筋拉小車，橡皮筋剛好恢復原長時紙帶上的點）處。

人教版高中政治必修2民主選舉：投出理性的一票教案
教師活動：那種“選舉與我無關”，“選誰都可以”的想法，是公民意識不強、主人翁意識不強的表現。那么，怎樣才能行使好自己的選舉權呢？請同學們根據上面的學習，談談自己的想法。學生活動：思考討論教師點評：2、 如何行使好自己的選舉權（1）要不斷提高自己參與民主選舉的素養(yǎng)，端正參加選舉的態(tài)度，提高選舉能力，選出切實能代表人民利益的人。（2）要增強主人翁責任感和公民參與意識，積極參加選舉，認真行使自己的選舉權。（3）要不斷提高政治參與能力，在理性判斷基礎上，鄭重投出自己的一票。（三）課堂總結、點評本節(jié)內容講述了我國的選舉方式以及如何珍惜自己的選舉權利的有關知識，懂得我國是人民民主專政的社會主義國家，人民當家作主，應該增強主人翁責任感，自覺珍惜并運用好選舉權，以促進我國的民主政治建設，維護人民的根本利益。

（3）人民幣外匯牌價：我國通常采用100單位外幣作為標準，折算為一定數量的人民幣。如果用100單位外幣可以兌換更多的人民幣，說明外匯匯率升高；反之，則說明外匯匯率跌落。教師活動：大家知道匯率是經常變動的，為什么匯率經常變動？我國在美國、日本等國再三施加壓力的情況下，為什么保持匯率穩(wěn)定，人民幣不升值？學生活動：學生就老師提出的問題去閱讀教材；然后展開討論，并回答（4）保持人民幣幣值穩(wěn)定的意義教師點評：影響匯率變動的因素主要有：外匯的供求關系、通貨膨脹（或緊縮）率的差異、經濟增長率、利率水平、國家貨幣當局的干預與管制、市場預期、外匯投機活動等。外匯在國家經濟發(fā)展和國際貿易中具有重要的作用：通過匯率的升降調節(jié)進出口貿易；可以影響國際資本的流動方向和數量；可以影響國內物價水平；影響外匯儲備的實際價值等。
人教版高中語文必修3《馬嵬（其二）》教案2篇
結合歷史自古以來，江山美人歷來都是引無數英雄豪杰競折腰的，如果說英雄選擇了美人卻丟了江山，把所有罪名都歸結于“女人是禍水”。但是，紂王無道，和有了妲己有必然的聯系嗎？有人說妲己壞透了，壞透了的妲己如果不是取得紂王的信任是壞不起來的，紂王聽信了妲己的讒言，聽與不聽決定權在紂王，而不在妲己。強勢永遠在紂王一邊。再來看看西施和楊貴妃：西施是作為越國貢獻給吳國的供品來到吳王夫差的身邊的，楊貴妃更是先是李隆基的兒媳婦被看中而得寵的。所以，西施和楊貴妃這兩個可憐的女人根本沒有自己的獨立選擇，沒有獨立的愛情，如果沒有西施，就會有南施，或北施；如果沒有楊貴妃，就會有李貴妃，王貴妃，總之什么施，什么妃是不能少的，因為那是吳王和李隆基的需要。

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.
