1.整体设计思路、指导依据说明
本模块的话题是“A Lesson in a Lab”。

本课是一节语法课，训练学生正确表达各种比较级的能力。

本课注重多种不同形式的比较级的教学，将语法通过图片导入——提问——示例——归纳总结——强化练习等一系列的步骤传递给学生。

本课共设计了5个教学环节，运用“任务型”教学和多媒体辅助教学等手段指导学生进行语法训练,在学习过程中，强调发挥学生的自主参与意识,以达到新课标对学生综合能力的要求。

总之，整体设计思路遵循的教学原则是：
从总结规则熟练应用、从整体感知深层评价、从感性理性的原则。

2. 学生情况分析
教学对象是高一年级的学生，初步掌握了一些简单的形容词副词比较级的语法规则，具有一定的分析、概括能力，他们的英语基础知识和基本技能处在一个逐步上升阶段，因此，调动学生的学习兴趣，并引导学生进行扎实有效的学习是课堂教学的关键。

本课主要采用启发诱导的方法，从易到难，从提问到归纳的精心设计教学活动，给学生提高自我，展示自我的机会，激发学生的学习兴趣，让学生体验成功。

3.教学目标分析
教学目标应落实到与本课教学内容相关的具体语言知识或某项技能上，即：通过本节课的教学，重点解决什么问题（知识目标），达到什么样的要求（能力目标）1．知识目标学习并巩固与比较级有关的重点结构和句型：
倍数＋as＋形容词＋as…
倍数＋形容词的比较级＋than…
倍数＋the size ( length, width,height, depth)＋of…
“越来越……”
①单音节形容词/副词的比较级+单音节形容词/副词的比较级
②more and more+多音节形容词
“越…,越…”
The +形容词/副词的比较级+主+谓, the +形容词/副词的比较级+主+谓2．能力目标通过课堂教学活动，使学生形成良好的语言学习习惯，逐步形成归纳总结的能力，并最终形成一定的自学能力等。

学生在一定程度上形成自主学习、合作学习、信息处理、英语思维能力以及综合运用语言能力。
