Thinking of solving step in middle school mathematics' teaching

The purpose of the article is to explore the method of solving step knowledge in the middle school mathematics' teaching.The article instances the front-line teaching and uses the comparative method to achieve the goal of better teaching effect.This article puts forward some methods of solving step knowledge in the middle school mathematics' teaching by taking the teaching of linear equation in one unknown as an example.The writers show their common characteristics,compares their differences,analyses their advantages,disadvantages and maneuverability,and refers the knowledge of educational psychology to expound their different effect.Considering the character of education object,the expectation of teaching,the process of teaching,the rethinking of teaching,evaluation of the teaching effect,and so on,the writer put out the reasonable teaching method,which is mixing the advance organizer,discussion of teaching,mutual learning,expository method,and strengthening theory together,meanwhile,the writers make proper argument about the rationality of the teaching mode by considering learners,the targets,methods and evaluation.
