初中英语_人教版八年级下册unit7课语法练习讲评课教学设计学情分析教材分析课后反思

教学设计课前设计：老师精选测评题目，限定时间集中练习，老师提供答案，学生自主纠错，合作交流，提供给老师需要讲解的题目。

教师课堂活动设计：老师通过课件向学生展示一首与本节有关的英文小诗，为下一步的学习烘托气氛。

对于要讲评的题目，都配有相关的知识链接。

易错题集中讲完后，为进一步巩固本节知识点，老师又提供变式练习，使学生随堂达标。

学生课堂活动设计：学生要结合考点知识链接，先讨论后由小组长解读每个易错题，对于变式练习，学生可独立思考，可合作交流，然后展示自己。

在课堂活动中，教师要善于对每位学生察言观色，讨论情况，回答展示情况，保证良好的学习效果。

学情分析通过初中一年半的英语学习，大多数学生已能听懂有关熟悉话题的语段和简短的故事，能就熟悉的话题交换信息，能读懂短篇故事，能写便条和简单的书信，并具备了一定的语法基础。

学生在课前进行了自主纠错，合作探究并提交了需要老师共同讲解的题目，但由于各种因素的影响，学生发展参差不齐。

少数学生因为基础不够好，学习很吃力而自暴自弃，学生两级分化严重，本节授课内容不宜过多，用多种教学手段充分调动学生的学习兴趣。

效果分析通过本节语法专项练习的讲评，实现了预设教学目标,学生语法知识掌握较好，基本技能得到训练。

课堂上学生智力活动活跃，师生互动，生生互动，合作探究，百分之百的学生主动参与语言实践。

教材分析本套教材采用任务链的编写模式， a.提供听觉或视觉的输入信息引入主话题，作为真实任务目标的示范；b.提供本单元要完成的各项任务所需的语言知识、相关语境和训练形式；c.设计完成任务的输出形式（如，填表，做笔记，进行小组讨论，集体做游戏等）；d.完成任务，对整个过程进行评价.本节课重、难点是通过谈论有关地理和自然的话题，进一步学习学习形容词和副词的比较级和最高级的用法，学会用形容词和副词的最高级来描述个人喜好。

以及如何表达较大数字。

本单元应包括新授课、复习课、训练课、讲评课。

只有全面深刻的教材分析，才能很好地去组织教材、优化教学方法，写出可行的教学预案。
