摘要:
该初中英语教学设计聚焦Unit 5 Power of ideas Section A 2a-2d,核心知识点为含有情态动词的被动语态(情态动词+be+done)。通过复习一般过去时被动语态的对话练习搭建学习支架,如A:What's your favourite invention?等对话回顾旧知,再过渡到3D打印机相关听力活动引入新语法。
该资料以3D打印机为主题开展听说教学,特色在于融合语言能力(听前预测、信息提取、对话实践提升理解与表达)、思维品质(逻辑推断与信息整合)和文化意识(探索中国发明的世界影响增强家国情怀)。采用任务型教学与分层次作业,帮助学生内化语法,提升表达能力,教师可高效落实重难点,实现学科育人。

设计意图及二次备课
Step 1.Revision
Ask them to make a dialogue,:
A:What's your favourite invention?
B:My favourite invention is
A:Who was it invented by?
B:It was invented by...
A: What was it used for?
B:It was used for ...
Step 2 Listening
1)Before listening, ask the students to read questions in 2a and try to guess where Han Line went according to Question Two.
2)Play the tape and ask them finish 2a.
Where did Han Lin go last weekend ?
What was Han Lin’s favourite invention? why?
3)Help them to check the answers.
Maybe they can't write Exhibition.
Step3.Finishing task (2b)
1).Before finishing, ask them to try to tell the differences among these five sentences.Especially pay attention to “on, by and to”.
2).Ask them to try to complete the sentences with the correct forms of the words in the box.
3).Check the answer by listening to the tape.
Step 4.Listening
1).Before listening,ask them to try to guess what the 3D printer can make.
2).Play the tape and ask them to finish 2c.
3).Help them to check the answers .
4).Help them to make the sentences according to 2c like this :
Hearts can be made by a 3D printer .
...
Step 5.Practice
List the things they use every day and choose one that is the most useful for their lives.Then talk about what it looks like and what it is used for with a partner.
A: What invention do you like the most ?
B: I like... the most
A:Why?
B:Because....
巩固旧知识,头脑风暴开展对话练习,巩固一般过去时被动语态,提高学生的口语表达与合作能力。
听前预测,培养学生认真读题的好习惯,激发学生的兴趣,获取已知信息、逻辑思维能力,帮助建立听力期待,降低听力理解难度。
引导学生梳理3D打印完整流程,辨别介词on, by, to的用法,通过听力来检查答案,明确听力要听什么,带着目标去听,掌握听力答题技巧。
通过听力活动培养学生能够抓住并提取信息的能力,并做出判断以及信息整合及内化的能力。进而对未知文本做出有效预测,预测--求证,也符合学生的认知规律。
帮助学生内化听力中的语言表达,有助于激发学生的想象力。同时培养学生的语音模仿能力,让学生能够用正确的语音语调完成对话练习任务。
