高中英语教学案例分析Vocabulary learning in smart ways 二. 课型：学习方法探究课二. 教材分析 ：1. 教学内容：SEFC Book 6必修 阶段性词汇学习方法探究 （见文末）2. 教材处理：这是一堂笔者根据新的课程标准,结合本人对词汇教学方法的实践积累和思考进行设计的一堂探究课。该课创造性地选择了授课内容，对使用性较强的词汇方法进行了整理与补充，改变注重传授知识的倾向，采用“任务型”教学模式，进行了一次实验和探究。该课的中心话题是“三鹿毒奶事件”，内容引发学生对食品安全的关注和思考。该课旨在启发学生去思考自我梳理知识和自主学习的模式，让学习过程有一个延续的趋势。同时，提供一次实际运用英语表达交流思想的机会，增强使用英语的信心。 三、学情分析：笔者首先考虑为什么和怎么上这节课，使教学目标的设计实在可行。笔者的授课对象是属于三流水平的一个互助结对县中学，这个班为普通平行班，英语基础较差，但是大部分学生的思维活动、学习热情、表现欲望和合作精神是可以在平时的教学中不断提高和培养的。怎样使得一节课对学生今后的学习有所思考和帮助，也是笔者要考虑的问题。综上因素，根据学情，笔者采用活动式的教学方法上一堂关于词汇学习的课，期待对今后的学习中新旧知识的连接有所帮助；同时注意运用鲜活真实的语言材料吸引学生，提高学生答题的兴趣，同时便于设题。兼顾设计内容简单化，便于调动全班学生的积极性，在互动中实现教学任务和目标。四、教学目标1、学习并改善词汇学习的效果；2、能根据词汇的构成特点，归纳整理学习和记忆的方法；3、增强社会责任感，关注和谐社会的发展。 五、设计理念： 高中英语新课程标准加强了对词汇的要求，高中阶段从原来的18002000个增加到3300个单词和400500个习惯用语或固定搭配，词汇量掌握的多少在一定程度上制约着学生运用语言能力的高低。 英语单词的学习既是一种挑战，又是一种磨练。新教材的词汇的特点大致可以概括为新，长，杂，多。学生投入大量的时间和精力但是效果不甚理想，影响了学习的信心和积极性。怎样继承传统的词汇教学的精华，把行之有效的方法介绍给学生是笔者一直思考的问题。掌握生词和短语除了坚忍不拔的毅力之外，还需要两样东西：已经掌握的单词和短语和不同的记词法。因此，将生词与熟词以各种方式捆绑记忆，是诀窍之一。心理学研究表明，经过归类的知识要比零散的知识记得牢固。因此，综合运用多种记忆法，将词汇以链式或发散式的形式联系，而非一盘散沙，是诀窍之二。这样，既可以系统整理要记忆已经学会的词汇，又可以使其以有效的方式扩展词汇量。六，教学手段：多媒体辅助教学七、教学过程：Step I leadin Skill one: the diversion of words part of speechGreet with a typical tongue-twister.1.

But when the day came, he got cold feet and let the chance slip for a lack of confidence of speaking English before a large audience. Finally, after my encouragement he took part in it. I suggested he practice repeatedly before the competition, which helped to put his best foot forward to the jury. We often feel afraid to speak with a native speaker.

A true friend is someone who reaches for your hand and touches your heart. Truly great friends are hard to find, difficult to leave and impossible to forget. One friend in a lifetime is much, two are many, three are hardly impossible. Fate chooses our relatives; we choose our friends. Strive to make friends, for life without friends is like life on a desert island. To find one real friend in a lifetime is good fortune; to keep him is a blessing.Step III SummaryStep IV Assignment
