The types of wisdom classroom are mainly divided into standard wisdom classroom, discussion-type wisdom classroom and wisdom classroom. Based on the needs of teaching activities, the overall realization of comfortable, information, intelligent learning environment. Relying on information technology, it will deeply integrate modern educational technology with education and teaching reform, lead classroom teaching reform, provide diversified classroom teaching means, and make teacher-student interaction become the norm in class. Through data collection and mining analysis, the teaching administration is assisted in teaching tasks and teaching quality decision-making. The basic functions of the wisdom classroom are as follows:
(1) Smart classroom teaching
intelligent interaction and information collection in classroom teaching, open up all aspects of the teaching process before class, during class, after class and after class, through intelligent transfer and push of resources, classroom interaction and Q&A, multi-screen interaction between teachers and students, group screen interaction and management, efficient classroom management and teaching information collection, etc. Innovative teaching models such as flipped classroom teaching, inquiry teaching and interactive teaching should be realized to promote the deep combination of new teaching models and information technology. Each electronic display terminal has interactive teaching, two-way transmission and other functions. Teachers can control the permission to switch the screen, teachers and students do not need to switch the network and other apps on the mobile terminal, realize the real-time screen projection of the mobile terminal screen, documents, photos, videos, etc. Teachers can display and compare the contents of each group on the main screen; The split screen has the function of students' independent interactive learning, which can be independently controlled and used as a terminal display device in non-interactive situations.
(2) Classroom live broadcasting
utilize uses the live broadcasting system to build low-delay interaction of passing videos, and combines multi-channel real-time live video, chat text, document content, etc. into single output through the professional broadcasting console to achieve diversified signal live broadcasting, restore classroom teaching in an all-round way, and realize classroom live broadcasting and interaction between schools and classrooms. At the same time, it can also realize remote teaching and other functions, which is convenient for teachers to carry out online and offline synchronous teaching.
(3) Classroom recording
The classroom recording and broadcasting system is used to achieve normal classroom recording and broadcasting, and the recording and broadcasting equipment can automatically record and broadcast a full range of regular classroom courses when teachers teach, and can be stored in the resource library platform of the school to achieve online live broadcast and on-demand, which helps the school to carry out micro-class and MOOCs teaching, and helps high-quality teaching resources to better communicate across schools. The system has the function of searching sensitive words for teachers' teaching content.
(4) Online course tour
Online course tour School administrators can log in to the computer platform for online course tour and real-time view of the class situation of each classroom: administrators can conduct multi-angle patrol when entering the classroom (including teacher panorama, teacher close-up, student panorama, student close-up, multimedia board picture); The manager automatically rotates the recording and broadcasting screen of each classroom on the platform, quickly completes the class tour of the whole school, and immediately controls the class situation of the whole school.
(5) Intelligent operation and maintenance control
carry out network remote centralized management of classrooms. Based on B/S architecture, the system has the functions of remote control of classroom equipment, classroom and equipment management, classroom inspection and so on. Achieve regular course live broadcasting, course recording, course on-demand and resource management to achieve teaching resource accumulation. The system supports automatic synchronization of the curriculum schedule of the educational administration system to achieve course linkage and unified management, supports localized deployment, supports docking with the digital campus system such as unified identity authentication and one-code pass, and can stably support more than 3,000 users concurrently.
Through the shoot, recording, broadcasting and pipe of the recording classroom, we can meet the needs of education informatization construction for application construction, fully unify network construction and application construction, and completely get rid of the trouble that there is no application available in campus network use. To solve the problem that the school does not have practical teaching resources for a long time, and students cannot review the content of this class after class. In order to ensure the normal teaching of teachers and reduce the complexity of teachers' operation, this scheme is a fully automatic real-time recording and broadcasting system, which mainly completes the automatic video tracking and acquisition of teachers and students, intelligent audio acquisition, computer screen capture of teachers, and intelligent video/computer screen guidance of teachers/students. The above signal source is automatically transmitted to the courseware real-time recording system to generate high-quality courses, and at the same time, through the classroom live broadcast system, live broadcast on the local area network and the Internet to provide remote users with online real-time learning platform.
About the camera：This scheme is equipped with two binocular cameras with automatic tracking system and a 6-camera recording and broadcasting host to realize the production and transmission of network media courseware resources.
About record:The recording system can record three kinds of signals, namely: audio, video and computer screen signals; The recorded files are suitable for network transmission; The recording system can automatically generate indexes according to PPT and WORD; In order to facilitate the use of courseware, the recorded courseware resources are packaged by HTML and FLASH, and can be viewed through the browser. Using the network method to record the teacher's teaching screen signal, the computer screen resource resolution is more than 1280×1024 (16:9,4:3 adaptive), to ensure no distortion, dynamic video can reach 30 frames/second.
About seeding：The recorded courseware has an effective means of communication, which can be transmitted through the campus network and the Internet, and can be viewed through the browser.
About pipe：Provide courseware publishing tools to publish the recorded media courseware resources on the server; Courseware service can effectively manage many media courseware resources; Provide customized development services to build learning websites of network media courseware resources.
The centralized control management platform is to integrate the classroom's remote multimedia control system, IC card system, voice intercom system, monitoring system, electronic lesson patrol system, high-definition live broadcast system, information release system, electronic clock system, Internet of Things control system, autonomous broadcasting system, asset management system and electronic class card system. Form a network, a platform, management teachers as long as you log in to an account can fully manage and control the school classroom, to give teachers comprehensive support, interaction and service. In the background, through the visual interface, a comprehensive understanding of the big data presentation of each device and system, and a comprehensive view of the use, status and management of the classroom. The online management of classroom reservation and borrowing can be realized through various ways such as one-card, two-dimensional code and public number.
The system consists of front-end hardware, intermediate transmission and background platform. Adopting a distributed architecture, the host is equivalent to the distributed node of the Internet of Things, and each module belongs to the end module, and is connected by M2M interconnection, and the result and control transmission are communicated with the node. The background platform supports C/S+B/S hybrid architecture. The realization of visual management is boring data concretization and graphics.
