The New Coronary Pneumonia epidemic affects the whole country, reducing personnel gathering and cutting off the transmission route have become the main prevention and control measures. Under the severe epidemic situation, the national education and training institutions have successively stopped offline teaching. The Ministry of Education also announced the extension of the spring semester originally scheduled to begin on February 17, 2020, calling on students to stay at home, not to gather, or to participate in concentration Sexual activity.
Responding to the online education of the epidemic to solve the urgent needs of primary and middle school students
. How to actively respond to the extension of school start and ensure the smooth development of education during the epidemic affects the hearts of all education practitioners. To this end, the Ministry of Education advocates "no suspension of classes" and encourages schools and educational institutions to transfer classrooms to the Internet so that students can complete their academic progress without leaving home.
This sudden outbreak has changed the original market structure of the education industry. Compared with the suspension of classes in major universities and the suspension of offline training institutions, online education has ushered in an unexpected opportunity and has become the best way to meet students' current learning needs.
Education bureaus, schools, schools and educational institutions around the country responded quickly. Enterprise service companies and technology giants took active actions and launched free policies and special technical support plans to gather resources and technical forces from all parties to step up to the "air classroom".
Compared with the traditional offline, "air classroom" refers to the online interactive education mode of online teaching and learning using modern information technologies such as the Internet and artificial intelligence. It is an important part of education services. It moves the lecture process to the Internet. There are no special requirements for students, as long as they can access the Internet, they can listen to lessons.
The "air classroom" is not restricted by region, and solves the problem of uneven distribution of traditional high-quality educational resources. Students and teachers do not have to visit the site to teach in person, saving many costs. The content of the course is open and transparent and easy to replay. Students have full autonomy to choose. They can also use the fragmented time of the Internet era to review after class. At the same time, combined with big data, artificial intelligence, VR, AR and other technologies, it can also achieve a high degree of matching of teaching style, teaching content, and student needs, which can fully stimulate students' interest in learning and improve learning effects.
Multiple positive online education has become the general trend.
China has always attached importance to education. In recent years, the development of online education in China has also ushered in many policy dividends. As early as April 2018, the Ministry of Education has issued the "Education Informatization 2.0 Action Plan", pointing out the importance of promoting the transformation and upgrading of education informatization.
In September 2019, with the approval of the State Council, the Ministry of Education, the Internet Information Office, the National Development and Reform Commission and other eleven departments jointly issued the "Guiding Opinions on Promoting the Healthy Development of Online Education", proposing to expand the supply of high-quality online education resources and encourage social forces to host online Educational institutions promote schools to increase research and development and sharing of online education resources, accelerate online and offline education integration, and build a policy system that supports the development of online education. This will undoubtedly bring many favorable policies for the development of online education.
With the huge domestic demand of students, parents, adults and other groups in online education, the market size of China's online education is also rising. According to the "2019 China Online Education Industry Market Outlook Analysis Report", the scale of online education users will continue to grow at a rate of about 15% in the next few years. It is expected to exceed 400 million people by 2024, and the overall market size will exceed 450 billion yuan. The "Internet + Education" market is ushering in a new round of talks.
How to create the best quality "air classroom"
with the outbreak of demand With the outbreak of "air classroom" during the epidemic, the number of online teachers and students has surged, the education platform and the educational information technology products, hardware equipment service providers, cloud services, and solutions behind it Solution providers are facing an urgent "big test".
How to quickly build an online education platform, realize the interconnection of teachers and students across the country, and ensure the best real-time audio and video communication multi-terminal interactive experience has become the first problem to be solved now. At the same time, various education bureaus and schools have special needs such as business security and copyright content protection.
So, what links do you need to focus on to build the best online education platform?
First of all, online education covers many business scenarios such as small class, large class, double teacher class, 1V1 tutoring, live broadcast of master teacher, recording and broadcasting, interactive question and answer, course management, etc. The video links involved include: video streaming, codec, audio 3A algorithm , Weak network transmission, encryption algorithm, multiplayer interactive live broadcast, player and other technologies, test the ability of end-to-end. Any missing or insufficient link will affect the teaching effect.
Secondly, online education scenarios have the characteristics of large bandwidth, long link transmission, and wide coverage. At the same time, due to the real-time and interactive nature of teaching, there are also high requirements for the low latency and anti-jitter ability of the network.
Thirdly, students are spread all over the country. Assuming that based on the principle of nearby access, online education platforms need to deploy access servers in major cities across the country. Theoretically, the more cities covered, the better the access effect and the more obvious the user experience improvement, but this Will face high costs. At the same time, facing a sudden business peak, the traffic has increased significantly, and the traditional IDC equipment room construction period is 3-6 months. It cannot respond to the rapid expansion of the platform in terms of server resources, bandwidth resources, and dedicated line resources. Learning experience.
In this way, whether the "air classroom" can achieve the best experience is closely related to many aspects such as video technology, transmission network and resource coverage.
Facing the challenge to use cloud's elasticity to end the problem The
epidemic is on the verge, and all sectors of the society have made a positive response and support. In the sub-battlefield of "suspending classes and non-stop schools", the power of cloud computing and technology has also played a key role.
Alibaba Cloud Video Cloud urgently launched a special support plan to release technology and resource dividends, provide personal technical support and customized escort service packages, and help various education departments, schools, and educational institutions to build multi-end remote teaching applications faster and more economically. And work with a number of SaaS partners in the education field to continue to support the establishment of "air classroom" in various places to ensure that primary and secondary school students can study at home in peace during the outbreak.
Based on strong resource elastic scalability, massive data processing capabilities and data intelligence capabilities, based on Feitian's ten years of technology precipitation and deep cultivation in the video field in the past three years, Alibaba Cloud will lead the video and network technology with Alibaba The deep integration of business scenarios has already created an intelligent, integrated, efficient, economical, stable and reliable video IT infrastructure service platform for vertical industries.
At the infrastructure resource layer, Alibaba Cloud Video Cloud builds a very fast content distribution network based on 2800+ global nodes, and implements security protection on top of the CDN to ensure business security and stability. At the same time, relying on the country's first full-coverage edge node to serve ENS nearby access, it achieves wide coverage, low latency, and high stability audio and video communication links. At the video application layer, Alibaba Cloud ’s self-developed RTC solution supports multiple teaching modes such as 1V1, small class, interactive large class, and double teacher class. The ultra-low latency live RTS service guarantees high concurrency and large class scenes are silky smooth , And video on demand and short video SDK also provide technical solutions for recording and after-class video playback.
In the face of the epidemic, technological rescue is equally important! Due to the current status of work stoppages and suspensions, the traffic of online education (including adult education) platforms has surged. Alibaba Cloud live video, CDN, edge node service ENS and other products have joined forces to help, and have provided video security for dozens of platforms and SaaS partners. Accelerate services and special technical support to ensure a stable and smooth interactive experience under high concurrency on all platforms.
To stop the epidemic with technology and resources, Alibaba Cloud is in action, and all technical personnel are in action. We can win this epidemic prevention and control battle!
