学生由小学升入中学，正值发育的第二个高峰期。这一阶段的学生精力旺盛，独立性、自尊心和好胜心明显增强。他们行事处世，都有自己的观点，但并不成熟；有自己的思维，但并不全面；有自己的行动，但缺乏对自我行为的责任感。对于学校与教师的管理，他们既没有小学生的绝对服? Students from primary to secondary school are at the second peak of development. The students in this phase are energetic, independent, self-esteem and ambitious. They have their point of view when they act, but they are not mature enough. They have their own thinking, but they are not comprehensive. They have their own actions but lack the sense of responsibility for self-behavior. For the management of schools and teachers, they do not have the absolute service of primary school students?
