合理利用信息技術,提高英語課堂效率

一、合理運用信息技術，激發學生學習興趣

“Go for it!”九年級Unit 7 “Where would Sam like to visit?”Section A. Task 1: 視頻欣賞旅游視頻。我適時加以提示補充，同時引入新單詞。Task 2: 目標語呈現。給學生展示世界地圖，提問：“Where would you like to visit? Why?”學生回答：“I would like to visit...”幫助學生用剛學的單詞講述理由：“Because I want a peaceful trip.” Task 3:我用幻燈片展示圖片Eiffel Tower， Sydney Opera， the Great Wall， Disneyland，逐張圖片提問:“Would you like to visit...? Why would you like to visit it?”學生:“Because it’s fascinating / relaxing / peaceful / educational / thrilling / fun.”引人學生熟悉的桂林、黃山、夏威夷、尼亞加拉瀑布、亞馬遜叢林、佛羅里達州和墨西哥等，提問:“Where would you like to visit? Why would you like to visit...?”

二、靈活運用信息技術，豐富英語課堂教學

執教“Go for it!”九年級Unit 9“When was it invented?”，重點是被動語態的學習。我播放了北京奧運會的開幕式上的煙花“腳印”和印刷術的視頻，引出中國古代的四大發明。學生看到壯觀而熟悉的場面時，激動而投入，我立刻提問：“These are two of the four inventions in ancient China. Do you know the other two of them? What are they?”學生回答后，我又問：“Which one was invented first? Do you know?”學生進行小組討論，從實踐中感受學習成功的樂趣，當他們整合出答案后，我說：“Who invented paper? Ts`ai lun invented paper， right? Who was paper invented by? It was invented by Ts`ai lun.”引出新的語法知識后，我展示電話、計算器、汽車、電視機和計算機的圖片，讓學生猜：“When was it invented? Which one was invented first? In what order do you think these were invented?”學生從英語課的練習中感受了歷史學科的魅力。在他們爭論不休時，我說：“Let’s listen to the tape and check your answer.”聽力結束后，在學生還有余興時，我通過電燈泡引出新句型：“Who was light bulb invented by? When was it invented? What is it used for?”利用自己加工過的圖片展示heated ice cream scoop，shoes with adjustable heels和battery-operate slippers，練習同一句型。

三、充分運用信息技術，擴展英語教學資源

“Go for it！”八年級(上) Unit 3 Reading “Do you remember what you were doing”涉及了“9.11事件”。學生不僅要從字面上理解何謂恐怖分子、恐怖事件，還要從政治的角度理解這事件對世界格局的影響。備課時，我用Google搜索到的相關圖片做成超鏈接。課堂上我先提問學生：“What happened to the World Trade Center?”點擊超鏈接，打開視頻：世貿中心被飛機撞擊時，總統先生坐在教室里聽課。然后呈現問題：

Where was President Bush when 9.11 attacks happened?

A. In the White House. B. In New York.C. In a classroom.

我提出下一個問題：“What was President Bush doing at that time?”一個學生回答：“President Bush was studying in a class.”她用了過去進行時，離正確的答案已經不遠：President Bush was sitting in a Florida classroom.
