“做功的過程就是能量轉(zhuǎn)化過程”，這是本章教學(xué)中的一條主線。對于一種勢能，就一定對應(yīng)于相應(yīng)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(yīng)從彈簧的彈力做功入手。然而彈簧的彈力是一個(gè)變力，如何研究變力做功是本節(jié)的一個(gè)難點(diǎn)，也是重點(diǎn)。首先，要引導(dǎo)學(xué)生通過類比重力做功和重力勢能的關(guān)系得出彈簧的彈力做功和彈簧的彈性勢能的關(guān)系。其次，通過合理的猜想與假設(shè)得出彈簧的彈力做功與哪些物理量有關(guān)。最后，類比勻變速直線運(yùn)動(dòng)求位移的方法，進(jìn)行知識(shí)遷移，利用微元法的思想得到彈簧彈力做功的表達(dá)式，逐步把微分和積分的思想滲透到學(xué)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(shí)例來創(chuàng)設(shè)情景，提出問題。給學(xué)生感性認(rèn)識(shí)，引起學(xué)生的好奇心；讓學(xué)生對彈簧彈力做功的影響因素進(jìn)行猜想和假設(shè)，提出合理的推測，激發(fā)學(xué)生的探索心理，構(gòu)思實(shí)驗(yàn)，為定性探究打下基礎(chǔ)。然后，引導(dǎo)學(xué)生通過類比重力做功與重力勢能的關(guān)系得出彈簧彈性勢能與彈簧彈力做功的關(guān)系。

【學(xué)習(xí)內(nèi)容分析】在行星運(yùn)動(dòng)規(guī)律與萬有引力定律兩節(jié)內(nèi)容之間安排本節(jié)內(nèi)容，是為了更突出發(fā)現(xiàn)萬有引力定律的這個(gè)科學(xué)過程。如果說上一節(jié)內(nèi)容是從運(yùn)動(dòng)學(xué)角度描述行星運(yùn)動(dòng)的話，那么，本節(jié)內(nèi)容是從動(dòng)力學(xué)角度來研究行星運(yùn)動(dòng)的，研究過程是依據(jù)已有規(guī)律進(jìn)行的演繹推理過程。教科書在尊重歷史事實(shí)的前提下，通過一些邏輯思維的鋪墊，讓學(xué)生以自己現(xiàn)有的知識(shí)基礎(chǔ)身于歷史的背景下，經(jīng)歷一次“發(fā)現(xiàn)”萬有引力的過程，因此體驗(yàn)物理學(xué)研究問題的方法就成為主要的教學(xué)目標(biāo)?！緦W(xué)情分析】在學(xué)太陽對行星的引力之前，學(xué)生已經(jīng)對力、重力、向心力、加速度、重力加速度、向心加速度等概念有了較好的理解，并且掌握自由落體運(yùn)動(dòng)和圓周運(yùn)動(dòng)等運(yùn)動(dòng)規(guī)律，能熟練運(yùn)用牛頓運(yùn)動(dòng)定律解決動(dòng)力學(xué)問題。已經(jīng)完全具備深入探究和學(xué)習(xí)萬有引力定律的起點(diǎn)能力。所以在推導(dǎo)太陽與行星運(yùn)動(dòng)規(guī)律時(shí)，教師可以要求學(xué)生自主地運(yùn)用原有的知識(shí)進(jìn)行推導(dǎo)，并要求說明每一步推理的理論依據(jù)是什么，教師僅在難點(diǎn)問題上做適當(dāng)?shù)狞c(diǎn)撥。
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(dòng)：那種“選舉與我無關(guān)”，“選誰都可以”的想法，是公民意識(shí)不強(qiáng)、主人翁意識(shí)不強(qiáng)的表現(xiàn)。那么，怎樣才能行使好自己的選舉權(quán)呢？請同學(xué)們根據(jù)上面的學(xué)習(xí)，談?wù)勛约旱南敕?。學(xué)生活動(dòng)：思考討論教師點(diǎn)評(píng)：2、 如何行使好自己的選舉權(quán)（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(shí)能代表人民利益的人。（2）要增強(qiáng)主人翁責(zé)任感和公民參與意識(shí)，積極參加選舉，認(rèn)真行使自己的選舉權(quán)。（3）要不斷提高政治參與能力，在理性判斷基礎(chǔ)上，鄭重投出自己的一票。（三）課堂總結(jié)、點(diǎn)評(píng)本節(jié)內(nèi)容講述了我國的選舉方式以及如何珍惜自己的選舉權(quán)利的有關(guān)知識(shí)，懂得我國是人民民主專政的社會(huì)主義國家，人民當(dāng)家作主，應(yīng)該增強(qiáng)主人翁責(zé)任感，自覺珍惜并運(yùn)用好選舉權(quán)，以促進(jìn)我國的民主政治建設(shè)，維護(hù)人民的根本利益。
