随着社会转型和国家改革开放的不断深入,教育领域中出现了流动儿童、留守儿童等弱势儿童群体。~[1]调查表明,流动儿童由于受地域文化的差异和陌生的环境、父母的教养方式等因素影响,其学习适应能力、自信程度等均低于平均水平。~[2]伴随城市化进程的加快以及外来务工人员的增多,广州市南沙区逐渐出现较多的流动儿童,如大塘小学全校共398名学生,其中195名为流动儿童,学校社区儿童和流动儿童的比例已经接近1∶1。在这样
With the social transformation and deepening national reform and opening up, disadvantaged groups such as migrant children and left-behind children have emerged in the field of education. According to the survey, migrant children are below average due to their differences in regional culture, unfamiliar environment and parental rearing patterns. With the acceleration of urbanization and the increase of migrant workers, more migrant children are gradually emerging in Guangzhou’s Nansha District. For example, Datang Primary School has a total of 398 students, of whom 195 are migrant children, school community children and The proportion of migrant children is already close to 1: 1. In this way
