Module 4 Sandstorms in Asia 乐山一中 方毅教学模式介绍PWP教学模式强调以学生为中心，以活动为载体. PWP模式就是当我们关注学生的学习过程时，我们可以把学习过程划分为Pre-learning，While-learning，Post-learning三个阶段Pre-learning Pre-learning （学习前）阶段是教师进行教学准备、学生自我准备、教师激活学生学习新的语言知识、形成新的语言运用能力所需的知识、能力的阶段，其目的是为新语言内容的学习进行准备这一阶段包括是课堂教学之前的一切准备活动，也包括课堂教学中开始学习新的语言内容之前的导入、启动、复习、激活等活动While-learning （学习中）阶段当然就是学习新语言的阶段，一般是在课堂进行，但也可以是学习在课堂之外的自我学习活动在这一阶段，教师进行知识呈现、讲解，引导学生进行训练，学生通过学习掌握语言内容，形成运用能力Post-learning （学习后）阶段是学习新语言之后的评价、运用阶段，这一阶段应该是课堂之外的运用活动阶段，因为课堂内的活动本质上都属于学习阶段的活动，即使是课堂内的运用活动也是促进学习的运用活动。

PWP教学过程可以用于英语教学的每一项具体语言教学内容，在技能教学中表现为不同的具体形式，如听力中的 Pre-listening, while-listening和post-listening，口语中的 Pre-speaking, while-speaking和 post-speaking，阅读中的Pre-reading, while-reading和 post-reading，写作中的Pre-writing, while-writing和post-writingPWP课堂教学模式的教学环节：Pre-learning——While-learning——Post-learningPeriod 1 Introduction设计思路说明【Pre-learning】通过图片讨论沙尘暴的危害While-learning】 学习关于沙尘暴词汇以及讨论沙尘暴的起因Post-learning】讨论应对沙尘暴的方法教材分析本模块以Sandstorms为话题，通过本模块的几篇阅读材料使学生对Sandstorms有所了解，并通过文章中提出的一些深刻的问题，比如，The desert is only 250 kilometers away to the west of Beijing使学生更好地了解我们的地球和我们的生活环境正遭受的破坏，并引发对“我们应该如何保护环境”的热烈讨论，通过这些讨论会激发学生对环境保护的了解和实施的自觉性。

通过讨论Sandstorms，让学生表达对沙尘暴的看法，以及我们应采取何种措施来提高环境质量并能就此设计海报来呼吁人们保护环境INTRODUCTION 复习和学习有关自然灾害的词汇,呈现了一些自然灾害的起因以及造成的危害,使学生对沙尘暴有初步了解教学目标【知识与能力目标】Enable the students to talk about the sandstorms, the reasons for causing sandstorms and the important of protecting environment.【过程与方法目标】Help students to learn how to talk about the sandstorms, the reasons for causing sandstorms and the important of protecting environment.【情感态度价值观目标】To realize the importance of protecting environment.教学重难点【教学重点】How to describe sandstorms & environmental protection.【教学难点】How to express one’s opinions.课前准备1.
