    人教版高中历史必修3美术的辉煌教案2篇

    画中的诸多图像反映了画家对于传统绘画因素的吸收。那个怀抱死去孩子的母亲图像,似乎是源自哀悼基督的圣母像传统;手持油灯的女人,使人联想起自由女神像的造型;那个高举双手仰天惊呼的形象,与戈雅画中爱国者就义的身姿不无相似之处;而那个张臂倒地的士兵形象,则似乎与意大利文艺复兴早期某些战争画中的形象,有着姻亲关系。由此可以看出,毕加索不仅是一位富于叛逆精神的大胆创新者,同时也是一位尊崇和精通传统的艺术家。教师须强调:现代主义美术是现代美术流派的总称,现代美术流派众多,多姿多彩,但它们也表现出许多共同的特征。在技法上,它们大都反对传统的写实主义,追求新奇,空间结构错乱,色彩配置随意,点线紊乱,缺乏透视可谓它们共有的特点。在创作主旨上,它们都主张强调自我,表现个人情感和内心世界。可以说,现代美术艺术再现了20世纪西方世界的精神状况。

  • 人教版高中政治必修1树立正确的消费观教案

    人教版高中政治必修1树立正确的消费观教案

    教师活动:针对学生的辩论作点评、总结:(4)勤俭节约、艰苦奋斗勤俭节约、艰苦奋斗是我国的传统美德,是一种民族精神,而不是一种具体的消费行为。作为精神,它是永远不过时的。特别是我国还处在社会主义的初级阶段,生产力水平还比较低,还面临人口、资源等压力,我们更应该发扬勤俭节约、艰苦奋斗的优良作风。从个人思想品德的修养角度讲,有利于个人优秀品德的形成和情操的陶冶,是有志者应该具备的精神状态。当然,不能把勤俭节约、艰苦奋斗与合理消费对立起来,勤俭节约不是抑制消费而是说不要浪费。总之,以上四个原则,是科学消费观的具体要求,我们要理解和掌握这些原则,并用他们指导自己的消费行为,既有益于个人,也有益于社会,将促进个人的健康发展和社会的可持续发展。

  • 人教版高中政治必修1市场配置资源教案

    人教版高中政治必修1市场配置资源教案

    教师点拨:这则材料说明,市场调节有其局限性,单纯的市场调节具有自发性、盲目性、滞后性等缺点。市场调节不是万能的。社会生活中有很多领域和产品不能用市场来调节,如国防、治安、消防等产品的供给问题,枪支弹药、麻醉品等都不能让市场来调节。市场调节具有自发性、盲目性、滞后性。自发性:由于市场调节是在价值规律自发作用下进行的,在利益驱动下会产生一些违反市场原则的行为,如制造、销售假冒伪劣商品,大量排放废水、废气破坏环境,窃取他人智力成果等等。盲目性:由于人们不可能完全掌握生产各方面信息及其变化趋势,致使决策带有一定的盲目性。如某种商品有利可图则一哄而上,反之则一哄而退,从而造成资源浪费和消费得不到充分满足。滞后性:由于市场价格的形成和传递有一个过程,一旦传递到生产经营者手中进行生产调整,就有一个时间差,致使市场调节带有滞后性,成为一种事后调节。

  • 人教版高中政治必修1税收及其种类教案

    人教版高中政治必修1税收及其种类教案

    教师总结:近二十多年来,我国个人所得税的征收发展迅速,这也反映了我国经济水平、人民生活收入有了较大提高。与增值税的计税方法不同,个人所得税采用累进税率的计税办法,就是个人所得越高,税率越高,纳税人个人收入越多,缴纳个人所得税越多。这一特点从教材83页个人所得税税率表上可以看出。教师点拨:个人所得税的计算办法是分段计算的,个人收入800元以内不计税,多余800元以上部分,按不同税率分段计税。请同学们计算教材所列题目。学生活动:计算。应税所得额:4000元;不超过500元部分:25元;500――2000元部分:150元;2000――4000元部分:300元;累计所得税:475元教师活动:同学们想一想,这样计算个人所得税有什么意义呢?学生活动:认真思考,回答问题教师点拨:有利于增加财政收入,有利于调节个人收入分配,实现社会公平。(三)课堂总结、点评
