1、一整体思路说明： 运用多媒体辅助教学，将英语学习与游戏相结合，引导学生积极主动 的投入到学习活动中去。老师尽可能创造让学生说和展示的机会,把课堂 交给学生,通过设计活动,使学生在练习的过程中,习得语言。 二教学背景分析： 1.教学内容分析： 本单元主要学习有关反义词的英文表达， 反义词在二年 级曾经学过一部分,本单元的反义词是在原基础上的补充和提高。本课 是本单元的第3课，学生在前三课已经学习了有关dark-light, empty-full, strong-weak,wet-dry等词汇及用反义词简单的表述等。 本课主要学习clean和dirty的表达， 能用clean,dirty进行简单的

There are no. pond Apond B 九教学反思： 本节课上下来，整体感觉比较顺利。教学设计中的教学目标基本达到。学 生能够很好的掌握本节课的重点单词和句型。通过学生的听说读写能力均得到 了练习。课堂评价与本本课内容紧密相关,虽然pond是新单词,但在一开始,就已 经渗透在教学中。There be句型操练扎实,学生掌握较好。课堂生成方面比预期 要好,原以为学生只能按照我给出的句型来描述,但实际上,学生做到了从正反 两个角度来描述。如:The pond is clean.There are some fish in the pond.There are no trash in the pond.由此可以发现,学生真正学会,学懂了, 而且能够灵活运用。 不足之处是，时间没有把握好,写的训练时间比较紧张,每组只完成了一道 题。
