1、名师精编优秀教案课题与教学内容2 下雪的声音课时安排2 教学目标知识技能1.学会 17 个生字，会认字 8 个，会写字 9 个，理解“倏忽、翩翩而至、袅袅婷婷、窸窸窣窣、窃窃私语”等生词的意思。2.能正确、流利、有感情地朗读课文。背诵课文。3.初步体会比喻、拟人等表达方法在课文中的作用。4积累优美的词句。过程方法学生经历自主识字、初读感知、随文理解词意、再读课文、品味语言的过程，理解课文内容，用心感受下雪的声音，体会作者笔下所描绘的情境，提高学生的阅读能力。情感态度体会作者笔下描绘的情景，领略大自然的美好。名师精编优秀教案教学札记下雪的声音一课的重点句是：下雪的声音，与其用耳朵听，不如用心去感

2、受。对这一重点句的理解，我在课堂上是这样处理的，先让学生默读课文找出描写下雪声音的句子，反复朗读理解，学生能够准确地找到，也能体会到作者的描写都是用心去感受到的。但是让学生想想在生活中有过“与其用耳朵听，不如用心去感受”的体验吗？学生哑口无言，我想原因之一可能学生是对这句话的理解，只停留在课文中，他们并未完全消化与生活相联系。原因之二是学生不注意平时的生活积累，不善于发现生活中的问题。这大概也是学生语文阅读能力、写作能力差的原因吧！教学过程设计预设教学路径预设学生活动备择方案文档编码:CP2D8Y6H4C5 HD8B2K1O8S3 ZX5R9K6H2H7文档编码:CP2D8Y6H4C5 HD8
