三、反思
1.本文所設計的問題實際上是英語課與生物課中的“環保”章節的整合,學生較熟悉。老師讓學生列舉污染源,學生講出了很多的污染源——空氣污染、水污染、土壤污染、噪音污染等。
2.老師讓學生分組討論如何解決這些污染問題,巧妙地運用合作學習法,從而不但培養了學生探究問題和自主解決問題的能力,而且培養學生參政議政的意識。學生們以主人翁的身份,提出了種種解決方法。解決水污染問題,他們先用勸說的辦法,當此法行不通時,再借助新聞媒體的力量,最后上告政府;解決空氣污染問題,他們號召人們騎車上班。當老師提醒他們,若家離工作地方很遠,不能騎車上班時,該怎么辦?他們馬上想到了公交車。他們要求政府增加公交車輛,建造地鐵。
3.老師因勢利導,請他們回憶一下,以前有否做過有損于環保的事情。其實是英語課與政治課的整合。在這么和諧、民主、激動的氣氛中,學生們毫無顧忌,暢所欲言,紛紛講述了自己以前的不文明表現。當老師問他們以后還會做這種事嗎?他們很真心地回答:“No.”自然恰當的德育滲透,起到一箭雙雕的作用,使活動達到了高潮。
總之,整個過程,教師不是在“教教材”,而是在“用教材教”。教師根據學生的實際情況和生活經驗創造性地使用教材,從學生熟悉的知識入手,創設一個個與學生生活密切相關的問題情境,讓學生帶著問題思考,尋找解決問題的辦法。真正體現了《新課標》的精神:“在發展語言能力的同時,發展思維能力,激發想象力和創造力。”同時,也實現了“六環節”課堂教學中,堅持“以學定教、高效互動”的基本理念。
