基于问题解决的教学设计--以碳酸钠和碳酸氢钠为例

Teaching Design Based on Problem Solving--Take the Sodium carbonate and Sodium Bicarbonate for Example

实际问题解决就是教师和学生基于真实问题情境,通过探究、协作、对话来实现问题的解决。化学教学设计要以真实的生活情境作为问题线索,把知识点分散在这些真实的问题情境中,最后逐步引导学生利用所学化学知识解决生活问题。

Practical problem solving means that teachers and students should solve problems through inquiry,cooperation and dialogue based on real problem situation.The chemistry teaching design should take the real situation as the clue,scatter the knowledge points in the real situation,and gradually guide the students to use the chemistry knowledge to solve the life problems.
