一、教材分析
牛津初中英语八(上)第四单元以介绍野生动物及保护野生动物为中心话题。而本课作为本单元的最后一个课时,主要是进一步帮助学生掌握条件状语从句以及because和because of的用法,复习表示野生动物的词汇,并对本单元进行综合复习,进一步激发学生的学习兴趣和保护野生动物的意识。
二、学情分析
经过初一的学习,初二大部分學生能利用已学的英语知识进行简单交流。经过本单元前几课时的学习,学生对野生动物这个话题的相关词汇也有了一定的积累。本课的授课对象为宜兴外国语学校的学生,英语基础好,理解能力和开口能力也强。结合这些实际,笔者以创设情景、合作学习模式展开教学活动。希望完成本课时教材知识学习的同时,学生的团队合作精神、共同探索能力也可以进一步得到提高。
三、设计思想
笔者遵循任务性教学的原则来设计各项语言实践活动,创设真实环境,让学生利用所学知识解决实际问题,采用情景教学法、游戏教学法、竞赛法、合作学习法等多种教学方法。主要流程:导入——拯救熊猫“希望”——讨论保护“野生虎”。
四、教学目标
1.通过复述法、游戏法,学生能复习、巩固与动物有关的词汇和短语。
2.通过练习法、竞赛法,培养学生将名词归类的意识。
3.通过讨论法、归纳法,学生能进一步掌握条件状语从句以及because和because of的用法。
4.通过情景教学法、小组合作法,培养学生团队合作意识,锻炼其与他人协作的能力。
5.通过对野生动物濒临的危险和保护措施的讨论,学生能提升保护动物意识。
五、教学准备
知识层面准备:构思拯救熊猫“希望”的情景,把教材内容、复习回顾、游戏有机地组合在一起;创作阅读材料“野生虎”,并精心设计听、说、读、写各项拓展活动。
课件准备:上网搜索图片、背景音乐,制作多媒体课件。
