Especially in rural junior high schools, the proportion is even larger. I think there are the following reasons for the formation of post-graduation students: (1) Due to economic reasons, parents of rural junior middle school students are busy with their work and can not pay attention to their children’s study. (2) Rural schools, lack of experimental research equipment, the vast majority of experiments can not be carried out, so that students interested in intuitive experimental inquiry teaching mode can only become empty preaching model. (3) The lack of teachers’ teaching level, the initiative to explore and reform the teaching of law is not strong, the traditional model
