Teaching Practice of"Separation and Purification of Substances"in Junior High School Chemistry Based on Model Construction
Starting from"differences in the properties of substances",students are encouraged to engage in independent exploration and collabo-rative investigations into the separation and purification of substances.Through various modeling activities,students can gain a better understand-ing of methods and skills related to analyzing and solving problems,and effectively overcome potential misunderstandings related to the separation and purification process.By working with these thinking models,students can develop important scientific thinking skills,including critical think-ing,analytical and synthetic skills,and the ability to think creatively to refine ideas and methods.Ultimately,these activities can help build a more efficient and productive classroom.
