1、“学案导学”模式下高中英语写作教学中的实效性案例分析一、 背景1. 教材分析：本节课的教学内容为高中英语北师大版Module3 Unit9 Communicaiton Workshop “关于北京交通状况的报告”。学生在本单元积累了有关交通的词汇， 了解了目前的交通状况和有效地改善交通拥堵等问题的建议，因此，结合课文内容和生活实际，分析北京目前的交通状况，写一份分析报告是本节课的主要教学内容。2. 学生情况： 本课教学对象是普通中学的学生，英语基础比较薄弱，词汇句型积累较少，经常会出现对书面表达构思不够重视，不假思索，甚至逐词逐句翻译，致使作文的信息点叠加在一起，句与句之间逻辑联系不紧密，从篇

9、础不同，进行分层写作。基础较弱的学生可参考教师提供的写作提纲，补充细节内容。基础较好的同学可在领会写作方法后，能较详尽地体现出实质内容和各部分之间的逻辑联系，大胆地独立完成。在这一过程中，教师巡视，给与学生必要的帮助和指导，特别是帮助指导一些有困难的学生。查看学生写作的内容要点是否齐全，表达是否准确，用词、句型结构的使用是否正确，单词拼写是否有误，语法结构的数量和准确性，上下文的连贯性以及语言的得体性。鼓励学生在完成这一任务的过程中应用较多的语法和词汇，合理使用较复杂结构和较高级词汇。Write a report about the transport situation in Beijing
