The courseware management unit faces students at the same time, and negative messages of teachers can cause bad influence on the students, so the message unit board is independently arranged in the video management unit.
The search unit in the teaching resource management module enables a teacher to search needed resources more efficiently, and only keywords of course contents or teacher names are input. In this embodiment, the searched ranking includes downloading amount ranking and message amount ranking, and may be selected to be arranged in a descending order according to the downloading amount or the message amount of the teaching video, the courseware management unit defaults that the message amounts of all courseware are zero, and the courseware ranked in a descending order according to the downloading amount after searching.
The search unit enables students to search courseware of teaching teachers more efficiently, and only the keywords of teacher name, subject and teaching chapter are input.
A teacher with a teaching authority can initiate voting on the voting module and appoint students in a certain class group to perform anonymous voting.
After the voting module is arranged, when the opinion divergence occurs and data statistics is needed, the problem can be solved in a non-name voting mode. For example, the teacher may ask for the arrangement of the content of the next lesson, and the teacher explains the new lesson to teach new knowledge and the job explanation to perform a periodic test, and then may initiate a vote, and specify students of the corresponding class to perform the vote, and determine the content of the next lesson according to the voting result.
The student can vote according to his will without any contraindication in some voting (such as the cadre election).
