教后反思：

本课时围绕“行路安全”这一话题，呈现了若干行路规则和安全知识，旨在引导学生树立正确过马路的安全知识。这一话题与学生的生活紧密相关，重点学习过马路的规则，在教学过程中我能联系生活实际，鼓励学生从自身的已有经验出发，说说自己日常的上学方式以及有关过马路的交通规则，并对学生的回答进行及时反馈。

在文本的学习中，我采取了总分总的方式展开，先让学生略读课文，对文本有大致的了解，接着集体学习有斑马线的情况下过马路的规则，并通过板书及图片带领学生复述文本，然后通过四个问题让学生自学没有斑马线的情况下过马路的规则，问题也许过于细化，所以课堂节奏较慢，最后通过图片法让学生自主归纳过马路一定不能做的事情，发挥了学生学习的自主性。

   由于文本存在一定的知识性，如何将其趣味性体现的更好，我为学生创设了一位母亲带孩子闯红灯的情景来让学生演一演交警，将红绿灯知识进行角色扮演，想法是好的，但在操作的过程中若能放开文本，发挥学生的创造性也许课堂效果会更好。

  通过这次的教学活动，我想我们应更关注学生的主观能动性，挖掘学生的无限潜能，让学生们爱上英语课，爱讲英语，爱展现自我。
