Technical Field

[0001] The embodiments of the present invention relate to the field of communications, and in particular, to a roll-call method, device, storage medium and electronic device. Background Art

[0002] Roll call in class is a basic and important interaction between teachers and students. Its functions include testing students' knowledge mastery, maintaining classroom discipline, and maintaining students' concentration. The traditional roll call method is related to the teacher's familiarity with the students. However, it is difficult for teachers to remember the names of many students. The following problems may arise when taking roll calls:

[0003] 1. When teachers call on students to answer questions, the choice of names is easily influenced by subjective impressions. For example, teachers often call on students who can remember their names, which leads to unequal frequency of classroom interaction between teachers and students. For students who actively raise their hands to speak, not being called on for a long time can easily dampen their enthusiasm; for students who do not speak, not participating in classroom interactions for a long time is not conducive to the development of learning and social skills.

[0004] 2. When students are absent-minded or whispering to each other in class, teachers who are not familiar with the students' names will usually use the method of "student in the x-row, y-number" or pointing with their fingers to locate the students. Students are prone to errors or misunderstandings when translating such instructions to specific individuals, resulting in inaccurate roll call information.

[0005] It can be seen from this that the related technology has the problem of poor roll call effect.

[0006] With respect to the above-mentioned problems existing in the related technologies, no effective solution has been proposed yet. Summary of the invention

That is, when the teacher selects a specific student, the student number, seat number, name, etc. of the specific student can be broadcasted by voice, and one or more of the student number, seat number, name, and face image of the specific student can also be displayed on the electronic blackboard. For example, the teacher determines the position of the person being called on the global auxiliary roll call interface image, and clicks on the position by touch. The central control processing unit matches the student information of the image coordinate position, and uses synthesized voice to announce the name and student number of the person being called through the speaker module.

[0043] In the above embodiment, when the target instruction is a switching instruction, the electronic blackboard can also be switched according to the instruction. For example, after the teacher completes the roll call, he or she can return to the teaching interface by touching and clicking the return button on the GUI.

[0044] It should be noted that the target instruction can be an instruction input by the teacher through the touch-screen electronic blackboard, or an instruction input through a terminal device that can control the electronic blackboard, or an instruction input by voice, gesture operation, physical button, etc.

[0045] In an exemplary embodiment, when the target instruction is a roll call instruction, the method further includes: determining the target student indicated in the target instruction; and updating the number of times the specific student has been called in the historical roll call record in which the target student is recorded. In this embodiment, when the target instruction is a roll call instruction, it is determined that the teacher has selected the specific student, and the number of times the specific student has been called can be updated in the historical roll call record of the target student, such as adding 1 to the number of times the specific student has been called.
