教学反思

本节课围绕发明的历史开展丰富多彩的课堂教学活动，学习过去时的被动语态的构成和

用法。首先以中国古代四大发明导入新课，教学过去时的被动语态的结构，吸引学生的学习

兴趣的同时很自然地导入新课。然后运用直观的图片针对发明时间和发明者对过去时的被动

语态进行操练，同时为听力和口语练习打好基础。

本课时的教学活动坚持任务型教学的策略，自始至终贯穿了以交际为目的的原则，无论

是谈论发明的历史，还是发明的用途，所有情境设置都非常贴近学生生活，让学生谈论时有

话可说，使听力练习有一定的语言基础。学生可以在任务活动中了解、学习、掌握和应用知

识。听说训练时，重视学习策略的引导，尽可能地为学生创设真实可信的会话情景，引导学

生积极参与对话练习，使学生在愉悦的环境里潜移默化地接受、领悟和使用语言。

教学反思

本节课教学目标明确、教学思路清晰、重点突出，充分体现了新课标的理念。

首先以看图对话和小组活动复习被动语态，培养了学生运用本课所学内容来解决现实生

活中的实际问题的能力，开拓了学生的思维。同时通过教师示范和图片提示为学生练习搭建

了平台，能够使基础较差的同学也在这个平台的帮助下与其他同学一起顺利完成任务。

形成性评价贯穿课堂始终，提高了学生学习的兴趣和竞争性。教师自始至终关注学生情

感，设计有挑战性的话题，激发了学生的学习热情；适时用激励性的语言赞赏学生，教师贴

切的评价既保护了学生的自尊心，又使学生焕发出了极大的学习热情，营造了一个宽松、民

主、和谐的教学氛围。

本课时采用任务型教学法，从练习、阅读到语法归纳，各种任务活动都是围绕重要知识

点设计，逐步深入。同时采用一些真实的任务活动，如让学生讨论中国茶文化，激发了学生

学习的兴趣和热情，寓思想教育于语言教育之中。
