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于傳統(tǒng)繪畫因素的吸收。那個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，同時也是一位尊崇和精通傳統(tǒng)的藝術(shù)家。教師須強調(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，它們大都反對傳統(tǒng)的寫實主義，追求新奇，空間結(jié)構(gòu)錯亂，色彩配置隨意，點線紊亂，缺乏透視可謂它們共有的特點。在創(chuàng)作主旨上，它們都主張強調(diào)自我，表現(xiàn)個人情感和內(nèi)心世界。可以說，現(xiàn)代美術(shù)藝術(shù)再現(xiàn)了20世紀西方世界的精神狀況。
