优点：1.从之前学习过的溶液导入，在通过蔗糖和氯化钠溶液的分析进一步引入溶液的定义
2.所选择的视频对于溶液形成的微观解释很生动，可帮助学生更好理解溶液的形成，在视频过长时适当和同学交流
3.宏微结合
4.对于溶液概念的关键点进行了诠释并举例
5.有突出重点的板书
6.和学生有适当的互动
缺点：有一处用词不够准确（水，或许蒸馏水更恰当）实在没啥缺点！
优点：从学生的已有知识入手，回顾学生所学的溶液；板书清晰，字迹工整
缺点：在视频播放时可以适当加入讲解，有意无意地引导学生关注重点
优点：1、利用实验视频：宏微结合讲解溶解现象。
2、PPT结合板书，思路清晰，阐述清晰。
3、注意知识点对于学生的易混易错之处：PPT直观图片，溶液不一定是无色。
缺点：1、可以在实验视频中加入一些讲解和介绍
2、语言科学性需要注意：严格来说，蒸馏水不是溶液，水是溶液。应该跟学生说明。
优点：1.从学生曾接触过的溶液来引出本节内容；2.通过视频对比，可以更易让学生理解溶解过程在宏观与微观上的表现；3.有意帮助学生理解溶液的均一稳定性质以及区分无色与透明
缺点：教学过程中，姿势较为拘束
