“Smart classroom“, as a typical smart learning environment, arises at the historic moment under the promotion of the Internet of things, cloud computing, big data and other emerging information technologies, and is the inevitable product of the development of school informatization to a certain stage.
“Multi screen” classroom refers to the smart classroom in which more than four screens are installed on the four walls of the classroom, excluding the computer classroom (multi screen of one person and one computer).
“Multi screen” classroom looks simple, but the technical implementation is more complex. Between multiple screens, a variety of different operating systems (such as IOS, Android, windows, etc.) and terminal devices (such as main screen, split screen, pad, etc.) need to be connected through wireless network, and the content or screen on the device can be shared to the user through a protocol supported by multi screen interactive technology by a certain software Other devices, to achieve multi platform screen sharing, multi screen interaction.
The trend of smart classroom transformation in domestic universities is not original in China, but an imitation of the construction of “future classroom” in Europe and America. European and American scholars believe that it should break the boundaries of formal learning and informal learning to adapt to the changing needs of the times.
Based on the characteristics of classroom teaching in Europe and America, small class discussion and group discussion learning have almost become a common norm. In order to deal with this kind of teaching mode, there is a “multi screen” equipment supporting group discussion and group presentation.
In Europe and the United States, the mode of multi whiteboard or notebook screen projection in smart classroom is called “group teaching multi screen interaction“. The complex environment requires stable, smooth and clear screen casting equipment. Bijie network optimizes the multi screen casting in the teaching process, significantly increases the transmission distance and image quality, covering the vast majority of mobile devices in the market.
After in-depth research and development, Bijie’s screen casting technology is more suitable for the screen casting habits of teachers and students, making teachers and students more focused on the ideas and contents of communication, and significantly improving the efficiency and quality of classroom communication and interaction.
