人教版高一英语必修二Unit3 听说课 课程教学设计
Unit3 听说课名师教学设计（一）Uni t3 ComputersListening and Talking教学设计【教材内容分析】本节课是人教版《普通高中课程标准试验教科书—英语（必修2）》Unit3 Computers workbook 中listening部分，本部分是本单元的第六课时，本单元是以“计算机”为中心话题的说明文，内容涉及计算机的发展历史、计算机的应用等。
整个单元多以计算机为第一人称进行自白，这种拟人的手法使得文章谈起来妙趣横生，抽象的专业知识介绍起来也浅显易懂。
本节课是以一则机器人广告为听力材料呈现在本单元的语言运用环节。
且以第一人称的口吻自述其本身特点、功能、及其价格等方面。
主要是让学生运用本单元所学的语言知识与阅读内容进行听、说、写的训练。
这样,既帮助学生巩固所学的语言及文化知识,也练习学生语言运用能力。
因此学习这节内容意义重大。
【学情分析】新课改的核心就是为了每一位学生的发展。
在我任教的高一年级的两个班级学生对初中阶段英语词汇及句法相对掌握较好。
所以他们平时擅长识记，但英语语言运用能力相对较低。
所以老师在语言运用教学中需要下功夫，做到合理选材,科学设计，有效练习。
我班大部分学生对英语有一定的兴趣，但其学习主动性,自主运用、探究学习的能力还有待于提高。
这就要求有梯度的设置任务，使用分层教学,提高学生的参与度，使不同层次的学生有机会展示自己,获得成就感，体验学习的快乐。
经过小学和初中的英语学习，他们已经积累了一定的语言知识，加上生活中对电脑的了解，学生已经掌握了一些与本主题相关的语言知识，为学好这一课打下了较好的知识和能力基础。
再加上学生是在练习了热身，读前和主阅读内容的基础上展开的，可以引导学生在原有的知识经验基础上通过听力来复习和了解新的内容，并通过解决问题的方式督促学生训练听力技能。
本班大多数学生比较活泼好动，因此只有投其所好,才有可能调动学习的积极性，为此我特意设计小组活动及合作探究的学习方法。
