第三篇：高中英語組教案檢查情況反饋
高中英語組教案檢查情況反饋
（一）、優點
1．教案質量普遍提高，教案與進度相符。教案完整、規範，備寫認真、字跡工整，內容充實、教學環節完備，教學過程詳細，説明大家都認真鑽研了教材。如覃智，魏小玲，嚴琴等老師的教案。
2．教案既有單元知識點、三維目標，語法功能的整體介紹，又有課時的知識目標，認知目標，重難點的介紹，而且教學過程詳細，教學手段靈活多樣，對每一課的知識點、語法內容分析透徹。如覃智、敖小梅等老師的教案。
3．對每一課的重難點把握的比較準確。如陳雯、餘祥英，陳惠貞，顏素文、嚴琴，等教師的教案。 ４．導學方式靈活多樣，能調動學生的學習興趣。如顏素文，覃智、敖小梅 魏小玲等老師。
5．板書設計圖文並茂，重點突出。如魏小玲，敖小梅老師的教案。
（二）、不足
１．部分教師的教案中的三維目標對能力目標和情感態度目標體現的不夠明確。
２．部分教師的各個教學環節銜接不自然。
３．個別教師在板書設計中沒有寫課題。
4．個別老師反思次數比較多，幾乎課課有反思，但是每次反思字數過少，甚至一兩句就結束了，沒有實效性和指導性。還有部分教師的反思次數很少。
三、建議
１．所有老師對教案、作業檢查應重視起來，多關心自己的教案、作業檢查結果，多從自己找原因。 ２．各位教師要深入備課，集體教研，才能取得良好的教學效果，教案寫得好的老師要全無保留的傳授經驗、方法，全面提高我校英語教師的整體水平。
３．備課要有針對性，要備符合我們學生實際的課。
4．教案要重視教學手段的設計，尤其要重視教與學雙邊活動的設計。
第四篇：高中英語話題作文教案
高中英語網
話題作文《成功》
一、話題導入
同學們，今天這節課，咱們來點輕鬆的，聊聊天，談談話，上一節輕鬆的話題作文課，怎麼樣？（稍事停頓，看同學們的反應，學生積極性）（今天來了這麼多老師聽課，。今天的話題，是大家非常熟悉也非常關心的——今天幾號了？（同學們答3月17日），相信同學們目前最大的心願就是大學聯考成功。好，咱們就來聊與成功有關的話題，
二、作文開講
（讀慢點，注重停頓和語氣） 有位老這不算什麼，還有大學呢；你大這不算什麼，你還沒有參加工作呢；你參加工作謀了你有了好位置，不一定就能扮好你的社會角色。只有你用自己的學識、聰明、勇氣和毅力贏得了社會財富，你才算成功了，但這也不是最後的成功。
這位老師對一名學習成績差的同學説：你國小沒考上第一名，這
高中英語網
不要緊，還有中學呢；中學沒考上第一名，這不要緊，還有大學呢；大學沒考上第一名，這不要緊，你將來還要走上社會呢；參加工作了，沒有謀個好工作，這不要緊，你還可以尋找；一時尋找不到，這也不要緊，嘗試着做幾件事，你就會對自己有所發現。你一直沒有成功，這不要緊，或許這是件好事，這反倒使你一直保持一種冷靜、。同學們對這個話題有了初步的理解，話題作文的由頭——“成功”（板書：成功，字寫大一點，居中）
1（選材）
絕大多數同學對話題作文的理解仍然停留在材料作文上，不自覺地被材料暗示的中心所左右，以至於寫出的作文千人一面，觀點雷同，沒有多少新意，這是當前的通病。因此，我在這裏需要非凡強調一下話題作文與傳統的材料作文的區別。所謂“話題”，就是談話的中心，就是引發談話的由頭。由某個設想好的“話題”所引
高中英語網
出的作文就是“話題作文”。也可以這樣理解：話題好比一個圓的圓心，從圓心到圓周上的任何一點連起來的線都可視為一個話題作文的寫作角度。而與此相對的材料作文的主題則必須從材料中提煉，行文也必須依循“引議聯結”的模式，具有很強的限制性。話題“成功”的選材朋友的成功，可以寫成功的感受等。（請3有把握的，有話可寫）題選材，題範圍，章來。如話題作文“呼喚”實在有偏題的嫌疑。
如何熟悉成功？[成功是什麼（宏觀、抽象）]，1、話題中的兩種成功觀，讓學生找出來，即文中加橫線的部分。2、現代漢語詞典解釋：成功就是預期目標的順利實現。3、聞名乒乓球運動員李楠的成功觀：“成功是努力的過程，是自己所鍾愛的事業的不斷進步，是
高中英語網
自己能夠為自己愛的人和愛自己的人帶來歡樂，是留在人生路上堅實而乾淨的腳印。”4、自己（曾嵐）的成功觀：成功是什麼？是我們生命中想達到我們的目標而奮鬥的過程，是一條線，而不是一點。5、其他（同學們的立意）[成功是什麼（微觀、具體）]1、每個人都有自己不同的成功觀點，可以分三類。一類：他們獲得到一世的功名，他們心中裝自己的同時心中容着天下人的成功。1在於征服，在於從士兵到將軍的過程。2世界的人都用我的視窗系統。二類：只因他們心中惟有自己沒有天下人。1高境界的實施。2三類：天。12、教師説：成功3、清潔工説：成功是天天早晨給人們不多
3、取一個吸引人的標題。（題目）
作文題目其實好比人的衣裳，就象報紙的標題一樣，往往起到搶眼的作用，有很多同學不重視，相當一部分同學是作文寫完了之後才草草地擬一個標題，有時候甚至忘記了，沒有標題，這是一個誤區，
高中英語網
要吃很大的虧。大學聯考閲卷老師平均兩三分鐘就改完一篇作文，標題的映象對於他給你的分值太重要了。因此，在構思文章的時候，把精力多用一點在題目上是十分關鍵和重要的。就成功話題作文而言，可以考慮擬如下題目，大家一起來比較篩選。一種方法是給話題前面或後想，一名高三學生的成功觀，作文內容或中心的體現。如(我們一定會做的更好)，讓我捧走等
4、寫自己最擅長的文體（形式）
議論文、
三、佈置作業
完成“成功” 提示：根據剛才對選材、審題、立篩選，確定自己熟悉的一個角完成整篇文章，當然成文時還要注重佈局某篇板書設計（略）
附：話題作文材料 高中英語有位老師對一名學習成績優秀的同學説：你在國小考第一名，這不算什麼，還有中學呢；你在中學考了第一名，這不算什麼，還有大學呢；你大學考了第一名，這不算什麼，你還沒
高中英語網
有參加工作呢；你參加工作謀了個好差事，這也不算什麼，有了好差事，你並不一定就有了好位置；你有了好位置，不一定就能扮好你的社會角色。只有你用自己的學識、聰明、勇氣和毅力贏得了社會財富，你才算成功了，但這也不是最後的成功。這位老師對一名學習成績差的同學説：你國小沒考上第一名，這不要緊，你還可以尋找；一時尋找不到，這也不要緊，你就世上本來就沒有最後成功的歸宿。
