七、Homework: 1.复习介词。
2.完成资料上的介词练习。
3.运用今天所复习的介词写写你的房间或你的教室。
反思：
今天，我给六年级的孩子们复习了in，on，over，under，near，in front of，behind等几个介词。按说，这要多少的涉及语法知识。但是，为防止挫伤孩子们学习英语的兴趣，小学不讲语法。
考虑到小学生的思维方式以形象思维为主，我决定将以上的几个介词“具象化”，而不再仅仅是讲单词那么“抽象”。于是在课件上，我运用色彩艳丽的篮子，并将猫放入篮子中，学生们脱口而出“in”，
4
接下来我又将书放在书桌上，学生们依然异口同声“on”，然后我不停地变换图片的位置：前、后、邻近、旁边、两者之间、上方...学会了基本的词汇后，我有示范并说出一个句子，如:Ms Jiang is in front of the whiteboard.让学生描述教室中人，物之间的方位关系。学生也会自然地回答出来。一个个介词，简简单单地就攻下了。
“生活即教育”，作为新时代的教师，要及时转变角色，教师不仅仅是“传道授业解惑”，更重要的是要发挥好“激趣启思导疑”的角色，在日常英语教学中，需要关注学生的生活世界，打破学生书本和生活之间的界限。书本和现实生活相比逊色很多，丰富多彩的现实生活对学生来说更有吸引力，让学生在课堂上也感受到生活化的气息，让学生的学习不再是一种负担，而变成一种真实、快乐、幸福、愉悦的体验过程。
课堂上要最大限度地创造生活化的语境，将课本上死的单词句子，以各种各样真实的生活情景展现在学生的面前，帮助学生更加具体、直观地感理解语言材料，让孩子们在真实的生活环境和语境下交流和学习，让学生认识到学习英语的乐趣和成就感，让学生的学习变得有声有色。
