初二第二课苍松柏4课时.doc

苍松翠柏1 课时：4课时 课时1 学习目标： 从作品中去了解中国画意境的表达。 如何去分析中国画。 中国画意境与中国文化的联系。 教学过程: 、自主学习： 1、阅读教材：本课《苍松翠柏》的教学内容是重点学习写意中国画的传统技法。以树的画法为媒介切入教学，进入到传统国画艺术中程式化表现方法的学习，《苍松翠柏》尝试引导学生运用中国画工具进行水墨写意的初步表现，并指向树、石组合的山水画写意小品练习松树树皮如鳞状，树叶如针状，这是松树区别其他树的最大特征。画松树皮用笔要苍劲有力，毛而不光，用墨较重，还要有变化，如受光部淡些，背光部就要重些。皴树皮不要一个个勾圆圈，要用长短不同、大小不同的方圆组成松皮，才不显死板。画整棵松树，树叶是由基本相同的单元组成，松针画法有半圆松针和圆松针两种，画松针时要注意参差错落和疏密的分布。画松针一般由外向里画，初学者可能画不准确，用笔往往不能集中在中心，只有通过不断地练习，才可以避免这个毛病。画松针用笔的粗细，要根据画面的需要来确定，比如有时近景的松树要求画得重些，松针用笔就要粗些，皴松树皮用笔更要粗些。松针一般着绿色或花青色。松树干一般着赭墨色（赭石加墨），也可以用赭石色按松皮的笔道勾勒一次。白皮松的树干要用淡绿色按松皮的笔道勾勒由披麻皴化出的两种基本皴法:(一)解索皴.以淡墨分左右,颤笔下勾,就像荷叶脉络一样由上往下颤笔拖下(也有荷叶皴与此大同小异)画解索皴可间以荷叶皴求变化,解索皴亦可以认为是放长了的披麻皴!注意:起稿即是曲折颤笔勾成.此皴法最适合那句口诀,千笔万笔不嫌多,一笔两笔不嫌少.全赖功力和风格定夺.(二)斧劈皴.有大小之分.其基本笔法一样,(宋.马远.夏圭最喜用此可观摩.明.王安洁王盖等亦法之)1 淡墨劈出大势(注意是劈出不是画出可体会用笔速度力度).2 次重墨重复勾石外廓(注意几何变化,已脱出披麻半圆基本形态)3 重墨干笔连勾带皴.丰富层次.(注意切不可多皴)4 贴石纹处以淡墨染,突出立体.5 最后点苔用小圆焦墨点(注意苔点的藏拙作用,既要提神又要掩盖败笔处需格外小心从事.还可在着色时加以调整.斧劈是山水画到一定功力时才能得心应手的皴法,所以披麻皴多练才会在画斧劈时打下线条基础. 重庆巴南中学初二美术导学案 主编：屈勇 审定：备课组 credit management: clear conditions and requirements for loan extension.
