      《節約用水》的優秀教案

      教案 時間:2019-01-20 我要投稿
      【www.51cxty.com - 教案】

        教學類型:作文指導課

        課題詮釋:

        水危機已經是全球性事實,而學生浪費水的現象時有發生,選定“節約用水”這個話題,抓住這一現象對學生進行教育極具現實意義和典型意義。課堂上教師通過創設情境、交流、合作等方法力求讓學生在頭腦中再現生活、認識生活、表述生活,從而最終能運用于生活。

        教學要求:

        1、認識生活,懂得節約用水,保護環境的重要性。

        2、在交流意見的過程中培養學生讀、說、寫的能力。

        3、培養再現生活、表述生活,從而最終運用于生活的能力。

        教學基礎:

        學生通過平時生活中的真實體驗,已有初步的節約用水的意識,但其對節約用水的重要性認識還不夠深刻,措施行為也不到位。五年級學生已具備一定的聽說讀寫的能力,但還需要創設環境,激發學生表達的欲望,從而引導學生從多方面認識水的重要性,力求使學生充分認識生活,讓習作成為表達的需要。

        教學重點、難點:

        1、以讀促寫,認識生活。

        2、雙向互動,表述生活。

        3、自我教育,讓水危機的意識深入人心,讓節約成為一種自覺的行為,讓習作成為表述的需要。

        教學過程:

        一、創設情境,再現生活

        1、情景再現:師扮作一位頭戴小紅帽的紅領巾走到水池邊,痛痛快快地洗完手、臉后,揚長而去。

        2、同學們,看到這種現象怎么無動于衷呀!難道不應該做點什么嗎?

        引導學生上前制止,通過交流指出學生制止的理由不充分。

        3、因勢利導:感謝這些同學的參與,他們不但有節約用水的意識,而且還能勸阻他人,真了不起!當面勸告,態度一定要誠懇,理由一定要充分,動之以情,曉之以理,這樣才能打動人心,使人心服口服。

        二、列出發言提綱

        1、那么如果請你去勸告,你準備從哪些方面引導,快快開動你的腦筋,想好了把它一條條羅列下來,這就叫發言提綱。

        2、誰想來說說你列的提綱?

        生:① 來之不易

        ② 用途很廣

        ③ 算賬

        三、以讀促寫,認識生活

        1、大家想得很周到,講得很有道理。老師這里有一份《珍惜每一滴水》的讀書卡,請同學們認真閱讀,看看講了些什么?

        2、結合自己的生活體驗,小組討論,從三方面入手,想想怎樣勸說最具有說服力。

        待會兒,我還扮演這位小朋友,請你們來勸阻,看看誰說得好,演得棒,我們就推選誰為“最佳勸手”。

        四、雙向互動,表述生活

        1、同學們,剛才練得都很投入,聲情并茂,連說帶拉。現在我請一組同學到前面來勸說,其他同學在下面聽,允許插話,人人都來參與,看誰有口有心,能說會道。

        2、情景再現。

        3、同學們,謝謝你們的幫助,從今以后,我再也不浪費水了,我錯了。(低下頭,取下紅領巾)我現在不是浪費水的小朋友了。

        4、評“最佳勸手”,并向所有參與的學生表示肯定。

        五、圖片解說,激發寫作

        1、欣賞圖片,配畫外音。(多媒體課件展示)

        2、怎樣節約用水?說說你的高招!(一水多用)

        3、同學們,不光是這位小朋友,目前浪費水的現象比較普遍,所以我們必須把自己的認識寫下來告訴大家,讓每個人都認識到水來之不易,作用很大,都節約用水。怎么樣?好,體裁不限,給大家一分鐘時間構思。

        誰來說說你的設想?

        ——記述事例 倡議書 童話 詩歌

        六、總結升華,布置習作

        水危機已經是全球性的事實,無數有識之士為此憂心忡忡。讓我們也從自身做起,從小事做起,樹立人人珍惜水,人人節約水的良好風尚。要像愛護眼睛一樣去珍惜水資源!不要讓人類的眼淚成為地球上最后一滴水!

        下節課以節約用水為中心,讓我們用我們的心、用我們的筆,來喚醒我們身邊的每一個人:愛一滴水。就是愛全世界。
