8、课本内容， 与高考中的应用文写作相结合， 让学生们学习书 信的一些常用句式和表达方法， 并且在理解课文的基础上， 进一步强 化他们的基础知识的学习，为以后的英语学习打下坚实的基础。效果分析新课程提倡自主、 合作、探究的学习方式，课堂教学是学生学习 科学文化知识的主阵地， 也是对学生进行思想品德教育的主渠道。 教 师应着力构建自主的课堂， 让学生在生动、 活泼的状态中高效率地学 习。如何才能提高课堂教学的有效性， 我在本节课中的教学中主要运 用了以下几种方法。一、温故知新，激发学生的学习兴趣“兴趣是最好的老师 ,有兴趣不是负担” , 这句话饱含深刻的道理。 对知识有浓厚兴趣时 ,就会产生不断前进

9、 , 渴求新知,欲求明白的强烈 渴望, 就会全身心的投入到所感兴趣的学习中。在教学中我从学生的 实际出发，首先复习 26 个字母的背诵和默写。学生刚刚学完字母， 这样通过背诵和默写加深了学生记忆， 及时的表扬增加了学生成就感。 让学生感觉到英语不是高不可攀， 而是很容易掌握。 让学生看着我课 前打印好的字母表，很容易找出缺少的元音字母。二、鼓励学生主动参与，积极交往 要使课堂教学真正成为高校课堂的主渠道， 必须着力唤醒学生的 主体意识， 让学生主动地参与教学活动。 在课堂教学中应坚持学生活 动的自主性， 使学生主体处于活跃兴奋状态， 使学习成为学生自己的 活动，让学生在教学实践过程中学会选择、

10、学会参与。例如在教授元 音字母的发音我通过听读、 试读、猜读等多种形式鼓励学生主动参与。三、巧设目标，提高学生对知识的吸收率 教学方法是教师借以引导学生掌握知识，形成技巧的一种手段， 要提高课堂教学效果，必须有良好的教学方法，深入浅出，使学生易 于吸收。在本节课中，我设计课堂教学目标时几次修改，最终定为初步感知元音字母的发音。通过大量的师示范读、领读等手段落实本课 的重点和难点。最后，我让学生之间围绕学习内容而进行互检互测。测试学生新课学习后教学目标达成率，检验学生运用知识、解决问题的能力。为 体现科学知识的实用与趣味性，练习题我尽量结合实际，且逐步递进, 这样的达标检测不仅能客观评价学生的学

11、习状况， 更可以激发学生进 一步努力学习的勇气。但与自己曾设想的效果还是有一定的差距。首先，在课堂形式上显得比较单一，和孩子们的互动不是很多， 替孩子们回答的较多，在课堂中出现的问题没能够灵活处理， 给学困 生的鼓励较少。其次，在知识的讲解上也存在一些问题，比如在新旧知识的衔接 上不够灵活。再次，小组合作学习时间太少，教师指导还不到位，只照顾到个 别小组。因此，汇报交流时，个别小组不太积极。总之，课堂教学是教师与学生的双边活动。 要提高中学数学课堂 教学质量，必须以学生为本，凭借数学思维性强、灵活性强、运用性 强的特点，精心设计，给学生一些机会，让他自己去体会；给学生一 点困难，让他自己去解决

12、；给学生一个问题，让他自己找答案；给学 生一种条件，让他自己去锻炼；给学生一片空间，让他自己去开拓。 注重学生优秀思维品质的培养，变被动为主动，变学会为会学，这样 就一定能达到传授知识，培养能力的目的，收到事半功倍的效果。教材分析Using language 部分主要是让学生们就“ What can we do about global Warmi ng ”进行讨论。课文中，欧阳光给关爱地球组织杂志写 电子邮件，请求帮助。杂志社在回信中指出，这个问题要靠大家的共 同努力。他们提出了几个建议： 1. 尽量减少电器的使用； 2. 尽量步 行或者骑自行车； 3. 回收能够再利用的物品； 4. 劝父母

13、多购买节能 产品；5. 植树；6. 宣传有关知识以影响更多的人。 通过课文的学习， 可以引导学生进行更加深入的思考， 从自身出发， 怎样做才能更好地 保护环境，保护我们的地球，以减缓全球变暖的趋势，为人类的生活 环境的改善做出自己的贡献。观评记录赵老师的这节课内容丰富， 思路清晰，很多活动设计也比较新颖。 同时，赵老师的个人学科素养非常高，语音非常标准，语言运用恰当 得体，与学生的互动也较好，课堂节奏非常合理并且紧凑，对课堂的 掌控能力也非常突出。在教学过程方面， 首先赵老师让学生初步感知文本， 从文本的题 材入手，让学生获取基本信息，比如写信日期、对象等。之后，引导 学生层层深入，逐渐加深对

14、课文的理解和把握。最值得一提的是，通过课文的学习，把情感目标自然地融入语言学习中， 让学生在学习英语知识的同时，深深体会到了自己在全球变暖这么大的一个课题面前，并不是无能为力的，而是可以通过自己的努力，让我们共同的家园有 一个美好的明天。总之，赵老师的这节课把知识与情感融为一体，巧妙结合，非常完美地实现了预定的教学目标，促进了学生英语水平的提高，取得了 良好的教学效果。评测练习【学习目标】1.
