Method and system for realizing real-time classroom interaction, and related method

Abstract

The invention discloses a method for realizing real-time classroom interaction. A student end is a mobile terminal, SSE push information is simulated according to a preset method, after a connection is established with an SSE server, the student end can receive related teaching instructions and data sent by a teacher end in real time and perform corresponding processing so as to ensure the instantaneity of classroom interaction items such as answering, asking questions, lock screens, and name-calling, meanwhile the resource overhead can be reduced, the technical complexity is reduced, and theproject maintenance cost is reduced. The invention further discloses a system for realizing real-time classroom interaction, and a method for simulating SSE push information in a mobile terminal.

Description

technical field [0001] The invention belongs to the field of mobile Internet information communication, and specifically relates to a method, system and related methods for realizing real-time interaction in classrooms. Background technique [0002] With the development of the mobile Internet era, information technology has penetrated into the field of education. The information-based teaching mode is mainly that teachers use multimedia devices such as PCs or all-in-one machines to teach, and students interact in class through mobile devices such as PADs or mobile learning terminals. Teachers can use PAD or mobile phone to teach, leave the podium to turn courseware pages, answer questions, ask questions, call names, lock the screen, send files, take photos and upload and compare student works, and also take pictures of the learning process for live video and other classroom interaction forms. This is conducive to improving students' initiative, enthusiasm, mutual assistance...

Problems solved by technology

Although this method is simple, it has many disadvantages

One is that many requests will be generated, which is a waste of pressure on the server and user traffic

The second is that the message is still not timely enough, regardless of the transmission time, the longest delay is the polling interval

However, WebSocket technology is also more complicated, including server-side and browser-side implementations that are different from general Web applications.

The performance is as follows: For front-end developers, it is often necessary to have the ability to use javascript driven by data, and it is necessary to maintain the ws connection (otherwise the message cannot be pushed); for back-end developers, the difficulty has increased a lot. The code for back-end processing business is more stable (don’t just crash the process and the framework), the second is that the push message is relatively complicated, and the third is that WebSocket is too new in the mature HTTP ecosystem, and there are not many components that can be reused
