Unit 6
When was it invented
Section B 1a-1e
一、教材分析
今天我的课堂阐述的内容是人教版《新目标英语》九年级全一册Unit6When was it invented (1a-1e).
本单元的核心话题是谈论发明，主要介绍了古今中外的一些重要发明。本课的教学内容与学生的实际生活密切相关，容易引起学生兴趣。本节课内容中的被动语态，是中考的一个重点，也是难点。学生必须通过学习能够正确地运用被动语态，对发明作出自己的反馈和评价，同时能够详细的用所学句型去介绍自己喜欢的或熟悉的发明物。
在新课程理念的指导下，结合本课的实际情况，我制定了以下核心素养:
(1)知识与技能目标通过本节课的学习，学生能够运用相关词汇和句型谈论发明物。并能进一步了解被动语态，并能模仿运用。
(2)过程与方法目标
通过情景对话、小组竞赛、游戏等活动培养学生的观察力和表达能力。通过听力及上下文的学习提高学生的听力技巧和逻辑思维能力。
(3)情感态度价值观目标
通过谈土豆条的发明让学生了解发明都偶然中的必然。
