高中英语新教材Unit11教案

一、教学分析

1、教材内容分析

本单元围绕“Scientific achievements”这一中心话题,从科学家、科学假说、科学理论、科学探索等方面设计听、说、读、写等一系列教学活动。“Warming up”部分设置了三个问题,要求学生就重要的科学成就进行讨论,从而帮助学生认识重要的科学成就,了解科学成就对社会发展、人类进步的重大贡献,同时激发学生热爱科学、投身于科学研究的热情,探索科学研究的方法。“Listening”部分设计了两道材料问题和一道开放性的情景话题。主要培养学生捕捉和筛选信息的能力,然后要求学生在一定语言输入后进行语言输出,旨在培养学生的想象能力和应用能力,通过自己的语言体会重大科学成就的意义。“Speaking”部分重点训练表达意图和愿望的日常交际用语,以五人小组的活动形式组织学生扮演科学家的角色,陈述各人的研究方向并阐明其重要性来申请科研经费。“Reading”部分为一篇介绍中关村的形成、发展及其重要意义的记叙文。通过对文章的理解,学习中关村人的创业精神。“Language study”部分由词汇和语法两部分组成,该部分不仅教授了四种构词法知识,更鼓励学生通过四项练习,运用构词法知识提高阅读能力。“Integrating skills”部分设计了一个阅读和写作的练习,在学生了解四大科技成就及其重要性后,要求学生略加扩充写一篇最伟大的科学成就的文章。“Tips”部分提出了说服性写作必须论点明确、论据充分,为写作提供了写作方法。

2、教学重点、难点:

本单元的重点在于借助“高科技成就”这一话题,学习、复习涉及这一话题的有关语言知识和语言技能(见教学目标),激发学生热爱科学、奋发图强、献身于科学的热情。

本单元的难点在于培养学生充分利用已有的英语知识表达自己,谈论科学家、科学成就、理想抱负。

二、教学目标

同时要求学生掌握本单元出现的构词法及一些常见的前缀后缀及词根的意义。

2、语言技能目标

通过本单元的内容培养学生良好的“听、说、读、写”的技能,使学生能运用所学的知识解决相关情景中的一些类似问题,并能结合所给任务,综合运用新旧知识解决问题,完成任务,在此基础上鼓励学生大胆地根据各自的语言基础与能力,有个性地解决问题,就科学成就提出独特的见解。

3、情感目标

教学反思

本单元的教学设计从学生实际出发,以科技成就为主线设计了若干情景与活动,旨在让学生积极参与学习活动,开口说英语,并使学生在轻松愉快的氛围中掌握语言知识,锻炼阅读理解能力。在教学实践中笔者体会到,教学应注意以下几点::

1. 学生在合作中学习更有助于提高学生学习的积极性,以及课堂参与的积极性。所以应当发挥小组功能,在合作中操练。小组活动是课堂活动的主要形式,如何落实小组中各个学生的角色是组织好小组活动的关键。这需要教师长期的训练。

2.设计活动时要充分考虑学生的情感态度,要设法让学生在快乐中学习。但教师不能片面地追求所谓的“快乐”,一味强调课堂气氛的活跃,而忽视学生对知识的掌握和对学生能力的培养。

3.信息技术的运用要为教学服务,不可喧宾夺主。在教学过程与信息技术的整合过程中,教师应注意信息技术只是一种辅助手段,不能由它控制全部流程。同时也应有效地利用这种手段,加快课堂节奏,增加课堂容量,提高课堂教学效率,使课堂气氛更加活跃,让学生在轻松愉快的环境中得到感情上的升华。

4.要处理好实践与反思的关系。反思是实践的一面镜子,能折射出实践中的成功和不足之处,以期在以后的教学中借鉴成功,改进不足。
