人教版新課標(biāo)高中物理必修1摩擦力教案2篇
l．知識(shí)與技能：（1）知道摩擦力產(chǎn)生的條件。（2）能在簡單問題中，根據(jù)物體的運(yùn)動(dòng)狀態(tài)，判斷靜摩擦力的有無、大小和方向；知道存在著最大靜摩擦力。（3）掌握動(dòng)磨擦因數(shù)，會(huì)在具體問題中計(jì)算滑動(dòng)磨擦力，掌握判定摩擦力方向的方法。（4）知道影響到摩擦因數(shù)的因素。2．過程與方法：通過觀察演示實(shí)驗(yàn)，概括出摩擦力產(chǎn)生的條件及摩擦力的特點(diǎn)，培養(yǎng)學(xué)生的觀察、概括能力。通過靜摩擦力與滑動(dòng)摩擦力的區(qū)別對(duì)比，培養(yǎng)學(xué)生分析綜合能力。3．情感態(tài)度價(jià)值觀：在分析物體所受摩擦力時(shí)，突出主要矛盾，忽略次要因素及無關(guān)因素，總結(jié)出摩擦力產(chǎn)生的條件和規(guī)律。二、重點(diǎn)、難點(diǎn)分析1．本節(jié)課的內(nèi)容分滑動(dòng)摩擦力和靜摩擦力兩部分。重點(diǎn)是摩擦力產(chǎn)生的條件、特性和規(guī)律，通過演示實(shí)驗(yàn)得出關(guān)系f=μN(yùn)。2．難點(diǎn)是學(xué)生有初中的知識(shí)，往往誤認(rèn)為壓力N的大小總是跟滑動(dòng)物體所受的重力相等，因此必須指出只有當(dāng)兩物體的接觸面垂直，物體在水平拉力作用下，沿水平面滑動(dòng)時(shí)，壓力N的大小才跟物體所受的重力相等。

人教版高中歷史必修3美術(shù)的輝煌教案2篇
畫中的諸多圖像反映了畫家對(duì)于傳統(tǒng)繪畫因素的吸收。那個(gè)懷抱死去孩子的母親圖像，似乎是源自哀悼基督的圣母像傳統(tǒng)；手持油燈的女人，使人聯(lián)想起自由女神像的造型；那個(gè)高舉雙手仰天驚呼的形象，與戈雅畫中愛國者就義的身姿不無相似之處；而那個(gè)張臂倒地的士兵形象，則似乎與意大利文藝復(fù)興早期某些戰(zhàn)爭畫中的形象，有著姻親關(guān)系。由此可以看出，畢加索不僅是一位富于叛逆精神的大膽創(chuàng)新者，同時(shí)也是一位尊崇和精通傳統(tǒng)的藝術(shù)家。教師須強(qiáng)調(diào)：現(xiàn)代主義美術(shù)是現(xiàn)代美術(shù)流派的總稱，現(xiàn)代美術(shù)流派眾多，多姿多彩，但它們也表現(xiàn)出許多共同的特征。在技法上，它們大都反對(duì)傳統(tǒng)的寫實(shí)主義，追求新奇，空間結(jié)構(gòu)錯(cuò)亂，色彩配置隨意，點(diǎn)線紊亂，缺乏透視可謂它們共有的特點(diǎn)。在創(chuàng)作主旨上，它們都主張強(qiáng)調(diào)自我，表現(xiàn)個(gè)人情感和內(nèi)心世界。可以說，現(xiàn)代美術(shù)藝術(shù)再現(xiàn)了20世紀(jì)西方世界的精神狀況。
