Whiteboard synchronous display method and system based on Android side smart classroom

Abstract

The invention discloses a whiteboard synchronous display method based on an Android side smart classroom, which covers the two aspects of a teacher end and student ends in the smart classroom. The teacher end and the student ends communicate with each other on the basis of the MQTT instant communication protocol through which a teacher and students can subscribe to the same topic. During the wholeclassroom activities, the teacher enables a whiteboard function in the teacher end, the teacher writes on the whiteboard and issues a message to the students who subscribe to the same topic, and thewhiteboard content is simultaneously displayed in the student ends. Whiteboard data generated during a teaching process will be reported to the backend server according to the xAPI education big datastandard. The whiteboard synchronous display method has lower requirements on hardware devices, and is particularly suitable for working in a one-to-many scenario where the number of devices is large,the computing power of the devices is low, and an network environment is unstable, can easily complete the teaching and interactive sharing of teachers and students, and uses a digital means to ensure the efficient exchange, sharing and aggregation of whiteboard content of the teachers and the students.

Description

technical field [0001] The present 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 quietly changing 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 learn anytime and anywhere. Smart classrooms are gradually changing the way people learn, bringing more convenient and efficient teaching tools and learning methods. [0003] Nowadays, the mainstream equipment in the classroom is to use...

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.
