Description
Technical Field
The invention belongs to the technical field of laboratory management systems, and particularly relates to an efficient, accurate, clear and standard laboratory attendance check-in evaluation management system and a management method.
Background
The laboratory is used as an important component of the school, and the quality of management plays an important role in the development of the school. Traditional laboratory management mode is manual operation mostly, does not have archival record or more with the paper form to the use and the maintenance of laboratory and records, saves, causes later stage information inquiry difficulty to be unfavorable for promoting laboratory management's efficiency and level. With the continuous development of information technology, computer technology, network technology and database technology are increasingly applied to various kinds of management, and the management of laboratories by using information systems will become a future trend. The application of computer technology will make the management means more perfect and the management data more uniform and rigorous. The laboratory management system is upgraded from relatively single laboratory maintenance into a whole-course laboratory management system integrating course management, personnel management, asset management and statistical management, and in addition, a mode of independently managing the laboratory by the laboratory staff is changed into a management mode of jointly participating by a college leader, a teaching teacher, a laboratory staff and students, so that the management quality of the laboratory is greatly improved.
In recent years, with the increase of college enrollment quantity, the biogenesis quality is continuously changed due to reasons of descending and admission, the learning ability and the self-restraint ability of students are different to a certain extent, some students can well utilize the autonomous life of colleges to reasonably arrange the learning time of themselves, but some students take ascending learning as the relief of learning, and the desire for knowledge is gradually reduced. Therefore, many colleges face the embarrassment of learning wind gliding and relaxing, and many students break away from the supervised education of parents after entering school and tend to autonomize in school life. Students are responsible for learning in the school books, but some students do not pay much attention to their own academic industry and are on the way to absenteeism. Serious absenteeism not only influences the order of teaching, also can cause the serious waste of teaching resource simultaneously, and the student can not form good study custom in the study, and this learning wind-force of school in the past also can receive the influence of different degrees, and certainly most mainly still leads to the fact certain influence to the student later development. As is known, the study performance is directly determined by the study initiative and the degree of bitterness, and attendance is a consideration of the study initiative of students and a direct reference reflecting the attentiveness and diligence of students.
With the development of science and technology and the improvement of living standard of people, especially the popularization of mobile internet, the number of surfing the internet by using mobile terminals is increased sharply, and at present, almost all students have a smart phone in high schools, wherein the number of Android operating systems is the first. The traditional attendance mode not only wastes teaching time, and inefficiency just appears the inaccurate scheduling problem of attendance very easily. However, with the progress of science and technology, attendance checking modes are more and more, and measures and tools for preventing 'card punching instead' are more and more. From the traditional paper attendance card to the fingerprint attendance, even the real-time positioning network attendance function software similar to the nail appears, and tools for enabling an attendance system to play a role are changed day by day. Therefore, the attendance system capable of improving the attendance rate of students, facilitating the attendance in class of teachers, saving class time and improving teaching efficiency is designed, and has very important significance.
