With the reform of the new curriculum reform, both parents and teachers are paying more and more attention to the issue of education, and as the subject that has just come into contact with the third year, the subject of chemistry, which is in line with the life, has also received much attention from the outside world. Of the teaching, the analysis of chemical exercises can be regarded as a major problem students, many students are difficult to use the method of analysis of exercises, making the problem and the efficiency of learning can not be effectively improved, resulting in the students’ chemistry It is difficult to be improved.This paper analyzes and discusses the analysis of junior high school chemistry problem to find the problems in junior high school chemistry problem analysis and find out the corresponding countermeasures and then improve and improve the teacher’s problem teaching to junior high students The analytical skills of chemical exercises to a higher level.
