Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0037] Such as figure 1 , 2 A method for distributing and answering test questions on a mobile terminal based on the MQTT protocol, comprising the following steps:

[0038] S1. The teacher-side application logs in to the MQTT server, subscribes to the "teacher" topic, and starts listening to messages from the MQTT server.

[0039] S2. The student application logs in to the MQTT server, subscribes to the "all students" topic, and starts listening to messages from the MQTT server.

[0040] S3. If the test questions sent by the teacher are in picture format, the pictures of the test questions need to be uploaded to the file server first. Otherwise skip to S5.

[0041] S4. The teacher terminal receives the URL path of the test question picture returned by the picture ser...

Abstract

The invention discloses a mobile terminal test question distributing and answering method based on a MQTT (message queuing telemetry transport) protocol. The method includes that a teacher sends test question information in a JSON (JavaScript object notation) format through a teacher side in mobile terminal, and the test question information is distributed to student sides in the mobile terminal through a MQTT server; after receiving test questions, the student sides answer the test questions and send results to the teacher side through the MQTT server, and the teacher scores the answer results of students after receiving the same. By the method, in the process of test question distributing and answering, if the test questions or the answer results are in a picture format, the test questions or the answer results need to be uploaded to a special file server or downloaded from the same; related data generated in the process of test question distributing, answering and evaluating are all uploaded to a special data statistical server, and all statistical data in the related data meet xAPI education big data standards.

Description

technical field [0001] The invention relates to the field of classroom teaching, in particular to a method for distributing and answering test questions on a mobile terminal based on the MQTT protocol. Background technique [0002] With the rapid development of mobile terminals and the mobile Internet, the digitalization of school classrooms has become popular. Compared with traditional teaching methods, using mobile terminals as teaching tools in the classroom can greatly improve the efficiency of many teaching links, which is very representative. The most important thing is the question distribution and answering link. The teacher only needs to set the questions on the mobile terminal and distribute them to the students. The students can answer immediately, feedback the results to the teacher, and record the answers for analysis and statistics. [0003] At present, this is only an ideal state that people expect to achieve, and there is no very mature way to meet people's ...
