教學內容分析
本文是人教版選修八第三單元Inventors and Inventions的Using Language中的閱讀文本。文章從功能上來講，是介紹Alexander G. Bell的名人傳記。通過文本解讀可以發現，文章主線是Bell和他的發明。不同于以往的人物傳記總是以明顯的時間線為順序展開，本文只出現了1847和1876兩個時間。其語言特點是除名言、引語部分外，文章主體以第三人稱、過去時描述Bell愛發明緣起于興趣，貴在有不斷探索嘗試的精神和行動。文章以microphone、telephone、tetrahedron shape等的發明與發現，串聯起Bell孜孜不倦地通過發明給人類社會帶來科技進步的一生，讓學生學習偉大發明家的探索精神、社會責任感并了解從problem到research再到solution的發明產生過程。
教學目標 At the end of this period, students will be able to:
1. identify the writing style and main idea of the passage by using reading strategies, such as reading the title, the picture, the first and last paragraphs. 2. find detailed information about how Bell invented his most important invention—telephone by scanning.
3. interpret some key sentences representing Bell’s values and merits by reading between the lines and thinking logically after discussing with teammates. 4. construct the outline of a biography by analyzing key words of each paragraph.
5. relate Bell’s spirit to self-development by following his example to improve the smart phone through logical, critical and creative thinking.

1. Who is the inventor of the telephone? 2. What aspects do you want to know about the inventor?
利用圖片，引出電話的前世——telephone以及它的發明者Bell。通過問題2引
導學生在潛意識中思考人物傳記往往會聚焦哪些方面，形成閱讀期待，為接下來的環節做鋪墊。

Step 3 Reading
1. 1st Reading (1) Ss read the title and the picture and predict the type of writing.
(2) Ss read the title, the first and the last paragraphs and figure out the main idea of the passage.

Para. 6 most famous saying Para. 7 most famous invention
(4) Ss summarize the outline of a biography.
基于語篇，設計活動：通過使用閱讀策略，讀標題、讀圖、
讀首末段、讀首末句、找關鍵詞等，引導學生概括、梳理、整合信息，并使之結
構化。比如關注體裁、概括主旨、了解結構等。

3. 3rd Reading:
T asks Ss to go through the passage and then each group chooses one question to discuss and share:
(1) What does the “woods” in his most famous saying mean and what do you think of his saying “leave the beaten track and dive into the woods”?
(2) Bell was born in 1847, do you know when he died? What do you think of “he made his first invention at eleven and his last at seventy five”?
(3) Why is Bell most often associated with the invention of telephone?

課后 反思
1、思優：
1）形式上：通過小組成員面對面的座位安排和貫穿課堂始終的小組計分模式，充分調動學生們的學習積極性和合作學習的氛圍，課堂上回答問題的學生面擴大了、回答問題的次數增多了；多媒體與板書運用相結合，兼顧課堂的預設性和生成性。多媒體的使用擴大了課堂的容量，節約了問題的書寫時間，同時通過加粗體、標顏色等方式使重點一目了然。黑板的使用及時把生成性的學生回答中的重點、優點進行了記錄，一是對回答問題學生的肯定，二是方便其他學生跟隨記課堂筆記。
2）內容上：通過整理文章主線，設計由易到難有內在邏輯的問題鏈，在閱讀以及做任務的過程中從結構、語言、思維三方面給學生充分的訓練和培養。由于“腳手架”搭設合理，在課堂上調動起了學生的知識儲備，在生成性回答過程中，學生甚至給出了Alexander G. Bell名言中的woods是指dilemma，而不僅是用difficulty這樣較為簡單的詞匯；從Bell他11歲開始發明，至死方休的事實中得出他是a lifelong inventor；對Bell發明的電話，學生評論時用了indispensable這樣的超綱詞匯，拓展了同學們的單詞量。
2、思過：
兩位同學在duty report的過程中，向同學們提問，并把他們的答案要點
寫在黑板上時，我沒有及時查看拼寫，有一個拼寫錯誤到后面我去板書時才發現并修改。
3、思改：
1）思維導圖（mind map）是一種很清晰有效的幫助學生提綱挈領的工具，我在板書傳記體文章的結構時應該使用它，而不是用傳統型的1、2、3點去標示。
2）對學生的板書我今后要及時給予反饋或修正。
