Under the background of big data information era,thinking mode needs to develop from low-level to high-level.The 'Ordinary High School Chemistry Curriculum Standards(2017 Edition)' also clearly stated that the development of students ' ' advanced thinking ' is the key to obtaining high-level chemistry core literacy and high-level academic quality.College entrance examination questions of electrochemical basis often involve the analysis and solution of problems in strange situations,which also require students to reside high-order thinking.Therefore,the cultivation of students ' high-order thinking should be emphasized in chemistry teaching.Problem solving mode is one of the common teaching modes in various subjects.How to integrate problem solving with high-order thinking in chemistry has become the focus of research.By analyzing the connotation and characteristics of chemical high-order thinking and the characteristics of chemical knowledge,the problem situation teaching mode was constructed to cultivate students ' chemical high-order thinking based on the problem situation and the experiment as the core on the basis of OBE(Outcome Based Education)teaching concept.What's more,combined with the general process of scientific inquiry,the practical points of the mode were put forward,which is to take the problem as the main line of thinking all the time to construct the classroom support to promote the formation of ' problem field '.The teaching will be carried out by adopting dual drive-the task and problem.This paper adopts the research method of combining theory with practice.After the theoretical framework is completed,the teaching content analysis,learning situation analysis and teaching design are carried out by taking ' electrochemical foundation ' as an example,and the teaching practice of ' raw battery ' and 'electrolytic battery ' is carried out in the experimental class.Then,the data analysis method is used to compare the changes of chemical scores and high-order thinking levels before and after the experimental class and the control class,and the practical conclusion is obtained : the teaching mode based on problem situation can effectively develop students ' high-order thinking in chemistry,especially in chemical experimental thinking and critical thinking.Finally,reflect on the problems existing in the whole research process,in order to implement and improve in the future teaching...
