The operating box is the ap under the umbrella of beijing knowledge impression technology ltd., which digitizes operations, digitizes data into daily teaching scenes and provides mobile operational tools for teachers and students. The workbox provides a whole-of-school k12, a full-scientific operating landscape, and an intelligent educational ecology from tool to content to big data. As of august 2018, the operating boxes had entered more than 70,000 schools in more than 400 municipalities in the 31 provinces and municipalities of the country, and more than 30 million primary and secondary school students and teachers were working with the operating boxes. At the student level, the method of working boxes is to resolve the submission of jobs, to fill out the objective questions directly, to upload the subjective questions, to reduce the burden on the school bags and to completely reduce the phenomenon of "forgotten workbooks", and to make it easier for students to complete the work assigned by their teachers. At the teacher's level, the first improvement in the work box is the teacher's experience: moving the office to free the teacher from office and working hours; reducing the volume of batches and making automatic changes in the selection of topics; reducing the cost of selecting topics by the volume library; and communicating with teachers and students at any time or place. The teacher's main function is a mass repository, which the team has always considered to be the focus. By the end of september, the public library will have reached the capacity of 4 million subjects, covering nine major subjects in primary and secondary schools. In addition, the workbox designs tools to enable teachers to upload their own subjectbooks and create a private library outside the public domain to meet the needs of teachers in different schools. (b) the work submitted by students, the choice of topics (single, multi-choice) does not need to be modified to see the results submitted by students; in addition, it is possible to see the selection of the specific name of each student for each choice, and the teacher prepares and delivers more targeted instruction. At the same time, it is clear to each student that he or she is a teacher of the results of his or her homework. After a certain amount of time, the teacher is able to look at each student's learning: the correctness of each knowledge point, the correctness of nearly 30 days, the performance of each student. On the basis of the student's operational data, the operating box is able to accurately depict the student's knowledge map and competency model, while the working data also serve as reverse data for the subject bank, helping teachers to flip class teaching and individualize teaching. The main function of student-end intelligence statistics for students is that the work is still done in the practice book, but the scene changes: open the business box client, enter the answer directly to the objective question, take a picture of the subject and file it in less than five minutes. When students submit their work, objective questions are automatically rated by the system, subject matter is modified manually by the teacher, who can also evaluate each subject. The students themselves also have access to the analytical data on the ap (the correctness of each knowledge point, the correctness of nearly 30 days, the performance of each student) in a timely manner. The work box aims to improve the efficiency of learning in this way, allowing students to achieve higher scores for less subjects。
