2學(xué)情分析 新入學(xué)的學(xué)生第一次接觸正規(guī)化的美術(shù)課,對(duì)一年級(jí)學(xué)生來(lái)說(shuō)是新 奇、有趣、好玩的,而且新生入學(xué)前所受的教育各不相同,心理因素 也不一樣,在繪畫(huà)上、工藝制作上一定有著自己的創(chuàng)造思維、想象能 力和自己的個(gè)性,但這些會(huì)造成學(xué)習(xí)的不一致性、習(xí)慣不統(tǒng)一化,給 美術(shù)課的課堂帶來(lái)不必要的麻煩。因此, 對(duì)待這些剛進(jìn)入課堂的小朋友, 我們?cè)谇楦袘B(tài)度上要做出很大 的努力,小學(xué)生在思維的想象力、創(chuàng)造力方面發(fā)展的空間很大,所以 我們要好好把握機(jī)會(huì), 激發(fā)孩子們對(duì)美術(shù)學(xué)習(xí)的興趣,讓孩子們能發(fā) 現(xiàn)美,有創(chuàng)造美的想法。
