Unit 3 Computers教學設計 篇2
【單元重點內容與教學目標】
本單元的話題是it技術，計算機的發展史和機器人。
warming up 部分通過展示算盤、計算器、計算機等圖片，引導學生思考計算機的不同形式，并要求學生運用“做決定”的表達。
pre-reading 提出兩個問題，引導學生談論計算機對我們生活的影響。引起學生對計算機這個話題的興趣。
reading 部分運用擬人的手法， 以第一人稱的身份按時間順序介紹了計算機的發展史。
comprehending 部分主要要求學生掌握以時間為線索的文章的特點，并能通過填寫時間表來歸納出文章的主要信息。
learning about language 部分的練習引導學生關注新出現的詞匯以及形容詞和副詞的區別； 并且通過仿照例子，初步掌握“現在完成時的被動語態”。
using language 部分的聽說讀寫都是圍繞不同形式的信息技術和不同種類的電子計算機各自的優缺點這兩個話題展開訓練。而且要求學生在聽說讀之后，能用上“做決定”、“ 推理”的表達法和“現在完成時的被動語態”進行報告，學會寫作關于機器人話題的文章。
learning tip 部分建議學生多從圖書館、報刊、雜志、網絡等途徑， 多方面來增加詞匯、提高聽說讀寫的能力。
【教學設計】
將 warming up 部分與 pre-reading, reading, comprehending 部分放在同一課時教學，設計成一節閱讀課。
將 learning about language 及 workbook （wb）中的 using structures 放在一起教學，上一節詞法、語法課。把 using language 中的 reading and speaking 部分的閱讀文章布置為課外閱讀作業。
將 using language 中的 listening and writing，speaking and writing（把 reading and speaking 中的任務改為“向老師銷售電腦”）和 writing 部分設計成一節語言運用課（1），重點是培養學生“說”的技能。
把 using language 中的 writing 部分布置為課外作業。將 wb 中的 listening、talking 和 listening task 結合在一起，設計成一節語言運用課（2），重點是培養學生的“聽”的技能。把 wb 中的u sing words and expressions 布置為課外作業。
將 wb 中的 reading task 與 speaking task 結合在一起，設計成一節語言運用課(3)，重點是培養學生的“讀”和“說”的技能。
將 wb 中的 writing task 設計成一節寫作評價課。
