  • 万里一线牵 说课稿

    尊敬的各位评委、各位老师,大家好,今天我说课的内容是《万里一线牵》。下面我将从“说教材”、“说学情”、“说教法”、“说程序”、“说板书”五个方面对本课进行具体研说,恳请大家批评指正。一、依标扣本,说教材《万里一线牵》是部编版《道德与法治》三年级下册第四单元《多样的交通和通信》的第三个主题中的内容。这个主题主要是了解多样便捷的现代通信方式;通过古今通信方式的对比,感受通信发展给人们带来的便利。本课教学通过帮助学生运用已有的生活经验和调查资料相对比,通过对知识的探究发现问题,从而使学生对现代通信方式的发展有初步了解,知道多种多样的现代通信方式,以及通信方式的发展给人们生活带来的便利。 二、以人为本,说学情对于现代通信方式,小学生使用的已经很广泛了,但是小学生真正运用现代通信方式解决生活问题的经验不足、缺乏体验,对本知识点的了解很少。因此,依据学生的生活实际和本课的教学目标,我以学生的生活实际为起点,利用课程资源,使教学与学生生活贴得更近,让学生更好的感受现代通信的迅猛发展,以及给生活带来的无限便捷,体验通信愉悦,并在以后的生活中学会合理运用通信方式解决实际问题,更好地服务于当下和未来的生活。
