Behind a good child, there must be a good parent who teaches him lifelong benefits. Tolstoy, a great Russian writer, said: "Without his father's pioneering example, all empty talk about educating children would become empty talk." There are only a few steps to a person's growth, and primary school to junior high school is one of them. The necessity of "connecting junior high school with senior high school" Primary education and junior high school education have the function of connecting the past with the future. The success or failure of transition has a great influence on the quality of education, but this combination is a weak link that has been neglected for a long time in basic education. Because primary school graduates have different levels of mastering basic knowledge and different cognitive premises, it intensifies the inadaptability of primary school students in learning, psychology and life after entering junior high school. This maladjustment is reflected in "teachers and students, teaching and learning", which is two-way and mutual. These maladjustments are mainly reflected in: the physical and mental changes of primary school students after entering junior high school, the difficulty of management, the contradiction with parents, teachers and schools, and the serious polarization. These problems have seriously hindered the healthy development of education. The main reason for this maladjustment is that the psychological age characteristics of freshmen are still in a state of semi-childish, semi-mature, semi-independent and semi-dependent, and consciousness and childishness are intertwined. In their eyes, middle school is a brand-new environment and a strange world: new schools, new teachers, new classmates, new teaching tasks and new teaching methods. Homework has increased from a few courses to more than a dozen courses, with more content, greater difficulty and higher requirements. In addition, they don't know much about the new study life, study tasks and standard requirements, so that most students are often in a passive state in psychology, study and communication, and can't adapt quickly, resulting in some students falling behind the times, taking detours and declining their grades.
