人教版新目标八年级英语下册Unit3第一课时教案设计知识讲解

教案一、背景新目标初中英语教材采用任务型语言教学（TASK-BASED LANGUAGE TEACHING）模式，融会话题、交际功能和语言结构，形成一套循序渐进的生活话的学习程序。

以学生语言技能、语言知识、情感态度、学习策略和文化意识的发展为基础，培养学生英语综合语言运用能力。

强调从学生的学习兴趣、生活经验和认知水平出发，倡导学生体验、实践、参与和交流来中发展学生的综合语言运用能力。

增加了情感因素、学习策略以及文化意识和跨文化交际能力等方面，体现了以人为本的教育观念，培养学生的终生学习能力，培养学生健全的人格和技能发展能力，提到了教育成功的核心。

任务型的教学模式，其过程应该形成一种师生交往、积极互动、共同发展的过程。

应该形成一种民主、开放的课堂教学氛围。

让学生在教师的指导下，通过感知、体验、实践、参与和合作等方式，实现任务的目标，感受成功。

在学习过程中进行情感和策略调整，以形成积极的学习态度，促进语言实际运用能力的提高。

二、课题：八年级英语（新目标）下Unit 3 What were you doing when the UFO arrived ?Section A (1a—2c)三、教材分析本单元教学以“不明飞行物到达时你在做什么？”导入，围绕“谈论过去发生的事情”这个这个话题展开教学，引导学生通过学习本单元的语言素材看图说话、句型操练、实际描述、对话表演，使学生学会用英语讲故事。

这个话题贴近学生的生活，让他们有话可说。

本单元的教材特点是话题集中，但句型不多。

主要语法内容为when 引导的时间状语从句及过去进行时。

我选取的是本单元的第一个课时，本课出现了大量的地点名词（短语）；一些实意动词；学习过去进行时及when和while 的用法。

四、教学方法用计算机辅助教学，以任务型教学法为主体，以小组活动，两人协作为依托。

以游戏、听力、口头练习和笔头练习为载体开展教学。

根据材料的信息,课后完成小短文来检查巩固这节课的知识。
