A whiteboard synchronous display method and system based on an Android smart classroom

Abstract

The invention discloses a whiteboard synchronous display method based on an Android terminal smart classroom, covering two aspects of the teacher terminal and the student terminal in the intelligent classroom. The teacher terminal and the student terminal communicate based on the MQTT instant messaging protocol. Through the protocol, teachers and students Can subscribe to the same topic. During the whole classroom activity, the teacher activates the whiteboard function in the teacher terminal, the teacher writes on the whiteboard and publishes the message to the students who have subscribed to the same topic, and the content of the whiteboard is displayed synchronously in the student terminal. The whiteboard data generated during the teaching process will be reported to the background server in accordance with the xAPI education big data standard. The present invention has lower requirements on hardware devices, and is especially suitable for working in a one-to-many scenario where there are a large number of devices, low computing power of devices, and an unstable network environment. It can more conveniently complete teaching interaction and sharing between teachers and students. Digital means ensure the efficient intercommunication, sharing and summarization of teachers and students' whiteboard content.

Description

technical field [0001] The invention relates to the field of classroom teaching assistance, in particular to a whiteboard synchronous display method and system based on an Android terminal smart classroom. Background technique [0002] With the continuous progress of society, the continuous development of the Internet, and the maturity of technologies such as big data and cloud computing, many industries have undergone revolutionary development. Human learning behavior is also changing quietly under the influence of the mobile Internet, and education informatization has developed rapidly in the era of big data. People's learning behavior is no longer limited to books and computers, and it has become a reality to use mobile phones to study anytime, anywhere. Smarter classrooms are gradually changing the way people learn, bringing more convenient and efficient teaching tools and learning methods.

AI Technical Summary

Problems solved by technology

[0003] Nowadays, the mainstream equipment in the classroom is to use electronic whiteboards, but traditional electronic whiteboards have the following disadvantages: 1. Limited use of space

The electronic whiteboard requires the operator to be in front of the electronic whiteboard to realize the corresponding control, which is not conducive to the interaction between teachers and students

2. Restrictions on interactive resources

This often conflicts with teachers' increasing demand for resource information. Teachers need to find additional resources according to their own needs, which is time-consuming and laborious.

3. Generate resource limitations

And multi-screen interactive technologies such as DLNA also have various problems: the device cannot perform other operations, consumes power quickly, is not stable, software compatibility is not good, and the content is not rich enough, etc.
