【Abstract】 taking the problem solving as the center to culture the students’dialectic ideation should base on the chemistry thought, the question chain structure of chemistry knowledge, and the dialectic in the thinking process of problem solving. The fundamental ways of taking the problem solving as the center to teach chemistry are to: (1) establish the teaching structure of problem solving; (2) establish the system of problem classification;(3) establish the reasoning mode based on the problems;(5) establish the mode of combining the experiment explore with logic reasoning;(6) establish the cognition regulation strategy system in which the problem solving is considered as the basic unit.更多还原
