高二—人教版—英语—选择性必修四
Unit 1 Science Fiction
Lesson 4 Using Language (1)教学设计
课 型:听力课——探讨机器人和人工智能
教材分析:
本次课程的听力旨在引导学生们关注“话语标记”,同时鼓励学生们就机器人和人工智能展开讨论。课本提供了两道听力练习题,其中第一道为文章排序题,学生一方面可以通过本题预测听力文本可能的话题方向,有利于锻炼学生的预测能力;另一方面,借助本题,可以有效的检测学生对听力文本的掌握水平。第二道引导学生关注听力材料中的“话语标记”,这有助于帮助学生抓住听力文本的逻辑,帮助他们进一步掌握听力文本内容。同时,这也能启发学生关注文本的逻辑性,对应用文写作有很大帮助。
学情分析:
授课对象为高二学生。完成听力的活动1对学生应当不成问题,但是关于文章的“话语标记”,学生可能已经忘记其概念,需要先让学生领读听力小技巧,弄清楚“话语标记”的概念再做听力的活动2。就机器人和人工智能,学生应当是有话可说,且感兴趣的,但是,专业词汇上,学生可能会不知道如何用英文表达,所以一定要在让学生发表意见前,给足时间让他们去讨论,查词,组织语言。
教学目标:
在本课学习结束时,学生能够:
1. 借助听力技巧,掌握听力文本大意,并完成相对应的听力活动题;
2. 结合已有知识,就机器人和人工智能相关话题给出自己的见解。
教学重点:
借助听力技巧,掌握听力文本大意,并完成相对应的听力活动题;
教学难点:
结合已有知识,就机器人和人工智能相关话题给出自己的见解。
