一、课例类型
高三写作课之润色训练
二、课例背景
随着新一轮课改轰轰烈烈地开展,我校掀起了一场“以学为主”的教学热潮。这节课即是本人参加学校“以学为主”赛课的一节课。这节课从备课磨课到开课历时一个多月,让本人真切体会和实践了“以学为主”的教学理念,受益颇丰。故以此课例与大家分享,希望能起到抛砖引玉的作用。
三、课例设计
1. 教学目标简述
学情分析:根据本班学生在2016年温州市二模书面表达(30分)得分的情况,全班40人,有36人得分集中在11-20分之间,班级均分15分。学生普遍渴望提高一个分数档次。
教学目标:在这节课,学生能够通过自己写,互相讨论并修改、润色的学习过程,体验并学习如何使用高级词汇和丰富句型。
教学难点:预测学生在现场作文中可能会用到什么的词汇句型,同时还得注意把握好时间的控制。
教学重点:引导学生使用高级词汇和高级句型
高级词汇: have a gift for; call for; significant; contribute to
高级句型: As we know,... It is known that... What is known is that... Difficult as/though cars are,...
The more..., the more
(注:因为这节课的发挥程度建立在学生的输出情况基础上,故教学的重难点还有一部分是学生现场生成性的。以上重难点是本人在备课时,根据学情和教材预设的。)
2. 教学程序设计
第一步: 导入 (阿Sa的两张对比照片)
(设计意图:唤起学生的注意力;指出漂亮的卷面是作文的高分的亮点)
第二步:回顾二模书面表达
(设计意图:从学生的实际出发,引发他们的困惑,为本节课的展开铺垫)
第三步:现场作文(一封本班学生来信)——情境设置
(设计意图:让学生觉得亲切,因为是本班同学的信;内容也是与本节课相切;信中涉及到许多的词汇和句型, 可作为语言输入,同时又是学生的输出活动,体现了“以学为主”的主题。)
第四步:小组讨论(协作学习)
随意挑选2份学生的作品, 幻灯显示
(1)找错误,并修正
(2)润色,使之更优美
(学生活动的同时,教师板书呈现学生的成果,并做适当的引导)
(设计意图:这个环节让学生能根据自身行动反馈信息来形成对知识的认知和培养解决实际问题的能力,以及合作能力,培养互助分享的意识)
第五步:江西高考作文润色
(1)分配任务,润色划线句子
(2)代表逐个上台展示成果,合作形成一篇作文
(设计意图:以真实的高考书面表达题最后让学生输出, 知识得到了应用而得以巩固。同时让学生自己呈现成果,让学生完成对知识的意义建构, 并体现了集体合作。)
第六步:家庭作业:改写整篇作文
(设计意图: 学生根据课上每个小组的分享内容, 合并自己小组的内容, 弥补课堂上由于时间原因,不可能完整写一篇作文的缺陷。 这不仅是在大家修改润色基础上延伸写作, 更是巩固本课堂内容的切实有效的手段。)
3. 板书设计

四、课堂实录片段
授课时间:2016年5月20日上午第5节
授课地点:本校多功能厅
授课对象:本校高三(2)班
实录片断:以下是本节课中第四步教师引导学生对同伴同学现场作文进行润色的精彩片段。
屏幕上显示学生现场修改过无误的六个句子:
(1)As we all know, English is an important subject, but I am not good at it.
(2)Although English is difficult, I dont give it up.
(3)I believe if I study harder, my English will be better.
(4)I think its important to improve English writing.
(5)Success needs hard work.
(6)I can make progress only by more practice.
以下是師生对话:
T: Now we have found all the mistakes of the 6 sentences. Now its time for you to polish the six sentences, making them more beautiful, more fluent and more elegant. You discuss with your group partners for one minute. And then every group shows your opinion. Here you go! (one minute later) Now, Group One, show me your groups opinion!endprint
S1: In sentence one, “ as we all know” can be replaced by” It is commonly accepted that...” or “It is universally acknowledged that...”
T: (板书以上两句) Good! Perfect job! Sit down please! (turn to Group Two) Group Two, how about your opinion?
S2: In sentence one, “ I am good at” can be replaced with “ I do well in...”
T: (板书do well in 和be good at) Do you remember we have learned another phrase which has the same meaning, “对……有天赋”?
S2: Have a gift for
T: (板书have a gift for) Thats it! You are so smart! (turn to Group Three) Group Three, its time for me to hear your voice.
S3: In Sentence Three, the word “ important” can be replaced with “ significant”.
T: (板书significant) Yeah, I agree with you! (turn to Group Four)Group Four, do you have a better opinion about this sentence?
S4: We can use “I attach great importance to improving English”, or “I cannot emphasize the importance of improving English too much.”
T: (板书以上两句) Fantastic! Wonderful! (turn to Group Five) What other sentences can be improved? Your group, please!
S5: Sentence Six, only放句首, 倒装句!Only by more practice can I make progress.
T: Wonderful answer! Thank you! (Face the whole class) What else?
S6: Sentence Four! We can say “Success calls for hard work”.
T: (板书call for)Wow, gorgeous! Ok, everyone,please look at the last sentence, who can polish this sentence?
S7: If I take pains to study harder,...; 或者If I spare no efforts to study harder, ...
T: (板书take pains和spare no efforts) Aha, terrific! You used advanced vocabulary! Who can use an advanced sentence pattern to improve it?
S8: The harder I study, the better my English will be.
T: (板书 The more...,the more...) Pretty nice! Now, translate my sentence “你吃的越多,你就越肥”into English.
S9: The more I eat, the fatter I will be.
五、教学反思
在备课时,我尽可能预测学生在现场作文中可能会用到什么的词汇句型,同时还得注意把握好時间的控制。但是虽然“法网恢恢”,但是现实中总难免还是有“疏漏”!在6次磨课中,每次上课效果都不尽一致,甚至是大相径庭。教学本身就是随机生成的东西,教学是一门有遗憾的艺术,没有最好,只有更好。为此,我们要在备课上花足工夫,才能具备“兵来将挡,水来土掩”的能力,才能把遗憾尽可能减少到最小。
