With the continuous development of multimedia teaching, teachers put forward higher requirements for the application of multimedia assisted teaching.

The research shows that many new problems are exposed in the process of using multimedia classroom, such as: frequently switching slides and blackboard writing in front of blackboard and multimedia platform, which limits teachers’ classroom teaching ability; the large amount of courseware information causes the accumulation of content, which makes it difficult for students to digest and understand the teaching content; the “intermittent” presentation of courseware, which separates teaching The teacher is too much rigidly attached to the content of the courseware.

In view of these problems, BJcast has constructed a new solution of four screen interactive teaching system, and made a beneficial exploration and attempt in the teaching mode and classroom construction, in order to provide a reference solution for the construction of smart classroom.

The interactive technology is based on the desktop wireless projection technology of the operating system. The traditional teaching software can only adapt to one screen and achieve full screen display and operation within the scope of one desktop. The four screen interactive teaching software adds judgment and processing in the case of multiple screens in the software logic.

When the device is connected to more than one screen, the software will create a software window that can cover more than one screen to make full use of the existing display space. With the double screen teaching software, we can control the contents of the two screens at will, which makes the application of this technology in the field of teaching possible.

By switching between different teaching modes, the multi screen interaction between the large screen of classroom platform and the screen of student group can be realized, and a demand of smart teaching for teachers in smart classroom in the future can be realized, so as to launch the smart classroom solution.

Aiming at the interactivity and two-way of smart classroom, this scheme integrates “two-way interaction, multi screen display and intelligent control”. It is mainly composed of “teacher teaching mode”, “group discussion mode” and “centralized display mode”. Between different modes, the teacher can install the intelligent management system on Android Tablet and windows computer for real-time control.
