背景技术Background technique

大多学校现在对学生的考勤管理还停留在手工管理阶段和计算机辅助管理初级阶段,信息反馈不及时,有时候让学校与家长的信息沟通会出现断层。身为孩子家长,会担心工作太忙,与孩子交流时间太少;仅靠有限的几次家长会和学校平时的不定期的反馈,难以传递足够多的学生在校情况给家长,有甚至从新闻媒体上可见学生由于逃课、出走等,家长和学校由于沟通配合不够未能及时发现,直至发生意外。Most schools currently manage student attendance at the manual management stage and the primary stage of computer-aided management. The information feedback is not timely, and sometimes the information communication between the school and the parents will be disconnected. As a parent of a child, I worry that I am too busy at work and have too little time to communicate with the child; it is difficult to pass on enough information about the students’ school status to the parents only by relying on a limited number of parent meetings and the school’s usual irregular feedback. It can be seen in the news media that students skipped classes, ran away, etc., and parents and schools failed to find out in time due to insufficient communication and cooperation, until accidents occurred.
