The classroom is the main environment for students to learn, and a good classroom environment plays a key role in improving the quality of teaching. With the continuous advancement of information technology, smart classrooms have gradually developed and matured, meeting the development requirements of educational informatization . Today, I want to share with you popular science, the development of smart classrooms over the years, what evolutions have passed, and what changes have occurred.
1. Multimedia classroom
The earliest and most common smart classroom is just a simple application of multimedia computers in the classroom – multimedia classroom. Multimedia classrooms are usually composed of multimedia computers, LCD projectors, digital video display stands, central control systems, projection screens, audio equipment and modern teaching equipment, and flexibly combine text, sound, image, video, animation and other media. Make the teaching content more vivid, vivid and intuitively displayed in front of the students. It enhances the appeal of teaching, avoids the trouble of teachers writing and drawing a lot, and improves the classroom efficiency.
However, the limitations of most multimedia classrooms are becoming more and more obvious at present, as follows: there are many types of equipment in multimedia classrooms, which are seriously fragmented and can only be controlled manually; multimedia classrooms are widely distributed and difficult to manage and maintain in the later stage; Only pay attention to the investment stage of hardware equipment, and the deployment design of the software application interaction platform is almost zero; the level of information application is low, and the technical scalability and scalability are weak.
2. Recording classroom
The recording and broadcasting classroom is another manifestation of the application of multimedia technology in the smart classroom. Through software and hardware, various resources and data generated in the recording and broadcasting classroom are recorded, processed, and processed in a centralized manner, and the generated teaching resources promote teaching research and teaching management, and enrich teaching methods to a certain extent.
The recording and broadcasting classroom can comprehensively record the whole process of teaching activities with high quality, and then through processing, to a certain extent, it can meet the recording tasks of video public lectures, quality courses, and distance education in some schools, as well as recording important meetings and academic reports. On the one hand, it enriches and enriches the school’s curriculum teaching resource library and improves teaching informatization; on the other hand, it allows advanced information technology to serve teaching more effectively.
3.Internet of things classroom
The Internet of Things classroom is a modern intelligent teaching environment based on the traditional multimedia classroom, which integrates the temperature and humidity, access control, and screen projection equipment in the classroom, such as linkage, environmental optimization and adjustment, and mobile interactive teaching. Intelligent identification, presentation, monitoring and management.
The Internet of Things classroom is an upgrade of the multimedia classroom, but at its root, there is no essential breakthrough in the teaching level. The Internet of Things classroom focuses more on the intelligent environment and equipment in the classroom, and does not pay attention to the teaching itself. The teaching scene is only limited to the classroom itself. Once teachers and students leave the classroom environment, it is difficult to carry out teaching activities.
4. Digital Classroom
Based on the advantages and disadvantages of the above-mentioned multimedia classrooms, recording and broadcasting classrooms, and Internet of Things classrooms, the digital transformation of the teaching environment is an inevitable trend, and digital classrooms have also emerged as the times require.
Digital classroom, which is what we usually call the teaching cloud platform, provides a full-space and all-round teaching scene, realizing the combination of online and offline, indoor and outdoor synchronization and ubiquitous educational resources Sharing and other functions.
Compared with all the smart classrooms mentioned above, the digital classroom will be very convenient for teachers and students to quickly use high-quality teaching resources shared on the Internet through digital technology and cloud optimization, so as to help teachers improve teaching efficiency and reduce the production cost of teaching resources, allowing teachers to focus on Teaching itself, in addition to
carrying out the whole process of integrating theory with practice, he also pays attention to the diversification of teaching scenarios and the multiple applications of teaching models, providing a ubiquitous environment for teaching, and realizing multi-level teaching online and offline, on-campus and off-campus, at the same time, it can also realize the teaching resources for everyone, and one for everyone, and promote the high-quality development of the “three classrooms”.
In short, the development of smart classrooms has gone through the process of “multimedia classrooms – recording and broadcasting classrooms – Internet of Things classrooms – digital classrooms”. The digital classroom currently under development aims to provide a humanized and intelligent interactive space for teaching activities ; through the combination of physical space and digital space, the combination of local and remote, the relationship between people and the learning environment is improved, and the learning space is realized. The natural interaction with the environment promotes personalized learning, open learning and ubiquitous learning. It also promotes the digitalization of the classroom teaching process and helps the comprehensive digital transformation of education as a strategic action!
