Pep 四年级上册Unit 5 《Dinner’s ready》Let’s spell
导入环节教学案例及优化

（1）优化前导入环节设计
本课的教学目标是通过学习学生能够感知-e结构的发音，并能够认读拼读符合规律的单词。导入环节设计如下：

T: Boys and girls, Let’s sing a song of the letter e.
“ Letter e letter e, /e/ /e/ /e/, the bed is red, the pet is in the net.”
T: Well done. Today we are going to learn another sound of the letter e. What is it?

（2）优化意图
课堂教学中，我发现，孩子们很喜欢这首欢快的歌曲，唱跳的很投入，课堂气氛一下子就被点燃了，但是却对顺其自然的导入新课没有什么帮助，很多孩子不明白，为什么字母e在歌曲中的发音是/e/，一下子又变成了/i:/，本来十分活跃的课堂也变得沉闷很多。因此我进一步优化了这个环节的导入方式，由于学生之前已经学过了字母E在-e-结构、-元音字母-e结构中的发音规律，因此我放弃了常用的歌曲导入法，改而设计了一个与已知相结合的帮助单词分类并回家的游戏，在复习旧知基础上自然导入新课。

（3）优化后导入环节设计
优化后设计如下:
T:Boys and girls, look, here are many words with the letter e, right? They can’t find their home, here are three houses, too. Can you help them to find their own home? Let’s have a try first.
