形容词和副词比较级和最高级用法复习课教案(9页).doc

-形容词和副词比较级和最高级用法复习课教案一、内容分析 形容词和副词的比较级和最高级是人教版新目标八年级重要的语法项目之一，是学生平时常接触的，它在很多题型中都会遇到。因此，复习好形容词和副词比较级和最高级的用法是十分必要的。因为这个语法项目是八年级学过的语法内容，在平时的练习中也经常地接触，所以学生对该语法比较熟悉。但是由于时间间隔长，所以某些语法点及其特殊用法可能有点模糊。二、学生分析语法向来是学生头痛的一项内容，这次任教的十六中的学生应该基础都不错，如果语法复习基本以呈现理论为主再辅以练习，相对枯燥，学生兴趣不够，容易分散注意力，所以我想溶入一些新的教学元素。这个年龄的学生争强好胜，喜欢带有游戏性质的教育，于是我考虑借用大家感兴趣的话题来激发学生的热情，利用习题竞猜的方式调动学生的学习主动性，增强学习的效果。三、教学目标 新课标指导下的英语教学应该以综合语言运用作为最终目的。语法应该成为帮助学生理解英语句子，表达自己思想和情感的工具。所以，我确定了本节课的目标为：学生能够在训练语言综合实践活动中熟练掌握形容词和副词比较级和最高级的用法。（1）语言知识目标：复习形容词和副词比较级和最高级的规则变化和不规则变化的构成，掌握形容词和副词比较级和最高级的综合应用。（2）能力目标：能够在听说读写中熟练应用形容词和副词比较级和最高级。（3）情感态度目标：在学习中培养合作精神。（4）学习策略目标：学会总结所接触的语言材料中的语言规律并加以应用。四、教学重点和难点  教学重点:进一步明确容词和副词比较级和最高级的规则变化和不规则变化的构成，熟练掌握形容词和副词比较级和最高级常见的几种特殊用法。  教学难点:（1）让学生积极融入到课堂氛围中，总是带着问题去研究；能带着遇到的疑问，为了灵活运用而大胆讨论。（2）灵活运用形容词和副词比较级和最高级常见的几种特殊用法。五、教学手段与方法以学生为主体，尝试创新思维。采用讨论、协作、探究、竞争的教学模式，引导学生灵活运用所学语法知识。利用多媒体计算机、网络资源、音像等创设教学情景、问题情景，扩大教学容量，增强教学的趣味性和时效性。六、课前准备 1、分发本节课的练习题。 2、教师准备相关多媒体课件。七、教学过程知识导入3分钟导入呈现呈现操练30分钟幻灯片练习发现规律幻灯片运用运用提高10分钟综合运用归纳2分钟小结教学流程图八、教学过程步骤一：导入(课前播放一首学生们熟悉的歌曲)Teacher: Do you like the song that you heard just now?
