设计理念与特色：
1.自编《变色龙》练习及阅读文本，让学生通过观察图片和结合科普知识回答问题，进一步掌握四个重点词汇的音形义；
2.在完成练习的过程中，引导学生自己观察找出规律，培养学生自主学习的能力和习惯；
3.在任务型活动中教学，强调运用。
呈现方式：讲授与演示结合，简单交互。
微反思：本节课是重点复习black，white，orange，brown四个词汇。学生在一二年级时已掌握对这些词的读音。通过自编的一篇含有这些词的练习和阅读文本，让学生对这些词汇音义形的掌握更加牢固。另外，本节课引用了小学生感兴趣的科普知识作为知识铺垫，激发了学生学习的兴趣。
微点评：本节微课结合文本再构的理念较好地突破了对重点词汇black，white，orange，brown音义形的理解。整节课的主线清晰，并能运用课外的知识，创设情境，让学生较好的掌握了重点词汇的义和形。最后的练习结合phonics，以及整合第二单元的问候用语，让学生进一步学会用phonics认读单词，并学会灵活运用问候语。课件制作精美有趣，激发学生学习的兴趣。
