　　1 Overview of Case Method
　　1.1 Main Concept of Case Method
　　Wikipedia has defined that the case method is a teaching approach that uses decision-forcing cases to put students in the role of people who were faced with difficult decisions at some point in the past；②The case method belongs to a complex teaching method，which is based on a problem structure or a structure of recognizing a problem；③“The case method combines two elements：the case itself and the discussion of that case.A teaching case is a rich narrative in which individuals or groups must make a decision or solve a problem.A teaching case is not a“case study”of the type used in academic research.Teaching cases provide information，but neither analysis nor conclusions.”The case was provided first for the students as the educational materials，then students use the case do the analysis，decision discussion in classroom.The case which would be selected with educational purpose and come from the real word.

　　1.2.1 Problem-based
　　Case method starts with a problem，and the problem must come from the real word.In different educational settings，different real word problem can be used in the process.We can generally speak that the case method based on the problem，and this kind of problem with large and complicative meanings as to be analyzed by students to put forward their discussion.
　　1.2.2 Students’discussion happened widely in class
　　During the case method process，after instructors provide the case information for the students，students can work in a group to analyze the case and share their ideas with each other.Students do the arguments together in order to put forward different solutions in their way.Those discussions reveal the students’mastery about the case.That’s a process which can develop student’s problem thinking ability.
