优点：1、从化学反应的分类入手，引出新的分类方法。引发认知冲突；一氧化碳还原三氧化二铁的反应不属于四大基本反应。
2、板书配合讲述，将氧化反应和还原反应的关系阐述的非常清晰。
缺点：知识之间的过渡有些生硬。
优点：
1.从化学反应的分类入手，制造认知冲突：一氧化碳还原三氧化二铁的反应不属于四大基本反应，引出新的分类方法。
2.有突出主题的板书，将氧化反应和还原反应的关系阐述的非常清晰。
3.和同学有适当互动
4.在练习的过程中引导学生发现问题：氧化还原反应不只是得失氧的反应，化合价才是更一般的本质
缺点：知识之间的过渡还需要再优化
优点：1.通过初中所学的四大基本反应类型入手，体现了巩固性原则。
2.语速适中，表达还是很清晰的。
3.板书字迹工整。
缺点：
知识之间的过渡有些不自然
优点：1.和学生互动性较强，主要引导学生进行自主思考，突出学生的主体性；2.思路清晰，通过一步步设置认知冲突，激起学生的学习兴趣；3.运用类比的思想，类比一氧化碳还原氧化铁、氧化铜；4.配合使用简洁的板书
缺点：1.要多关注学生一点；个人认为四大反应可以不作为引入，这样显得引入太过长，可以在后面讲
