    人音版小学音乐六年级下册龙腾虎跃说课稿

    聆听感悟—本环节是模式实施的重要环节,也是围绕新课程理念提高审美,落实教学目标的关键。在此,从学生学习的角度出发,又细化为三个步骤具体实施:1、初步感知2、深入体验3、复听感悟。这三个步骤的实施目的在于,使得学生对于音乐的体验和感悟呈现出一个由表及里循序渐进的过程。先是使学生获得初浅的整体印象,再由教师精心选择设计特色音乐片段共同聆听体验,并引导启发学生感悟音乐,使学生逐步积累一些欣赏音乐的知识,有意识地将听觉、音乐理论及自身感悟巧妙融合,形成学习和鉴赏的基本方法,从而提高对于音乐的感悟和鉴赏能力。其中复听感悟环节往往会受到乐曲篇幅及时间所限制,如本课《龙腾虎跃》一曲,如果完整欣赏一次需八分多钟的时间,因此,考虑到学生学习民乐的经验和实际情况,故作调整:将总体感悟乐曲放到第二课时进行。

  • (说课稿)部编人教版三年级下册《童年的水墨画》

    (说课稿)部编人教版三年级下册《童年的水墨画》

    一、说教材《童年的水墨画》是统编小学语文三年级下册第六单元的一篇精读课文,本文是一组儿童诗,由诗人张继楼的《溪边》《江上》《林中》三首小诗组成,以跳跃的镜头捕捉了乡村儿童的典型生活场景,展现了儿童生活的丰富多彩以及无穷趣味。 《溪边》一诗生动形象地描绘了儿童垂钓的场景。诗歌先描绘平静的溪水把人影染“绿”,再写水面钓竿上立着一只“红”蜻蜓,这一“绿”一“红”,既是和谐唯美的相互映衬,又是恰到好处的点缀,使画面充满了色彩美感;接下来,描绘了静静的溪水映着柳树、钓鱼孩子的倒影、钓鱼竿、红蜻蜓,空气都仿佛停止了流动,直到鱼儿上钩的一刹那,溪水动了,人影碎了,鱼跃人欢,画面顿时变得生机盎然。这一静一动的结合,是本诗的微妙高明之处。 《江上》描摹了一群水乡孩子江中嬉戏的欢乐场面。一群戏水的孩子,那样的调皮,像鸭群一样钻入水中,接下来“一阵水花”与“两排银牙”,将童年的烂漫快乐渲染得淋漓尽致,鲜活的画面仿佛定格在我们的脑海之中。

    部编人教版五年级下册《童年的发现》说课稿

    一、本节课的设计理念: 课题中的“发现”一词是本文的文眼,教学中引导学生从课题入手提出疑问,然后进行梳理明确主要学习任务。学生自主学习,了解“我”发现了什么,重点了解“我”是怎么发现的,理清作者童年时发现胚胎发育规律的过程。二、教材分析:本课是一篇鼓励求知、鼓励大胆想象、鼓励探究发现的课文,通过作者回忆童年时发现胚胎发育规律这件趣事,反映了儿童求知若渴的心理特点和惊人的想象力。第一部分先概述了“我”九岁时发现了有关胚胎发育的规律,却在后来因此受到惩罚。第二部分具体叙述“我”发现有关胚胎发育规律的前后经过。最后,写这个发现在几年后老师讲课时得到证实,“我”情不自禁地笑出了声,结果被老师误解受到处罚,但“我”从中获得感悟。本文故事情节充满童真童趣,语言风趣幽默,并有多处内心活动的描写,真实展现了孩子内心世界。

    新人教版高中英语必修3Unit 5 The Value of Money-Reading and Thinking教学设计一

    Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
