China’s students will now study online because coronavirus has shut schools
The news: China has launched a national cloud learning platform and started broadcasting primary school classes to ensure the country’s 180 million students can still keep learning even though schools are closed, according to state-run news agency Xinhua. A new school semester, scheduled to start today, has been postponed indefinitely as part of measures to combat the coronavirus. China authorities have encouraged people to stay at home to help reduce its spread.
School on TV: The approach differs by age. Primary school classes are being broadcast on one of China’s state TV channels. Junior and senior high school students in China can use an online learning platform which has 169 lessons covering 12 subjects for the first week, based on the national curriculum. Teachers will keep updating the platform with new materials as needed.
Bandwidth: The government has enlisted the China's three biggest telecoms operators—China Mobile, China Unicom and China Telecom—plus tech companies like Huawei, Baidu and Alibaba to back up the platform with 90 terabytes of bandwidth and 7,000 servers, ensuring up to 50 million students can use it simultaneously, according to state broadcaster CCTV News. About 600,000 teachers have also been using a livestreaming service called Dingtalk, built by Alibaba, to conduct online classes, the company said (although it has apparently not gone down so well with many students.)
