用袁隆平的故事做了版 思政选必三6.3课件

用袁隆平的故事做了版 思政选必三6.3课件

✅适用教材：高中思政选择性必修3

✅配套资料：PPT课件30P+教案

✨教学过程
1、导入新课
播放袁隆平《种子》MV 视频，引导学生在情境中感受推理魅力，自然引入本节课主题。

2、探究新知
🎯一、联言推理及其方法
以袁隆平水稻故事为引，引导学生分析推理有效性，师生共同总结联言推理组合式与分解式的形式、要点。

🎯二、选言推理及其方法
结合梦想与挑战素材，让学生判断推理结构，思考 “禾下之梦”，总结选言命题含义、真值及推理形式。

🎯三、假言推理及其方法
借袁隆平成功秘诀与小明小夏讨论，指导学生读文析理，梳理假言推理类型与有效推理形式，突破难点。

3、课堂小结与作业布置
梳理联言、选言、假言三种复合判断演绎推理的规则与有效式，巩固重难点；布置课后作业强化应用。
