Accompanying the reading and punching equipment, the whole family went into battle, and the parents shouted: It’s too difficult.

  CCTV News:In the current global war "epidemic", it is almost a problem that all parents have to face when their children go to class online. As soon as this online class starts, it’s not just children who are busy. Maybe parents are more tired than children. Many parents shouted: It is too difficult to be a parent! Compared with the past, parents’ financial, time and psychological burdens have greatly increased.

  Online course consumables buy buy buys learning costs. 

  In online classes, equipment is just needed. The first is a computer or a tablet computer or a mobile phone, and the hardware for video connection is definitely indispensable. Then there is the printer and copy paper, and you have to finish the homework assigned by the teacher after class. According to online shopping data in JD.COM, the turnover of students’ tablet computers increased by 95% and that of home printers by 16 times in the week just after February 2 to 11. Baidu search data shows that in the past 90 days, the search popularity of children’s mobile phones, children’s computers and student computers increased by 95% year-on-year and 106% quarter-on-quarter. At the beginning of the online class, the sales of printers, tablets and laptops increased greatly, whether it was an e-commerce platform or an offline store, or even "one machine was hard to find". 

  If you can’t buy a printer or don’t want to buy a printer at the moment, you have to spend money on printing, and this cost is not a small sum.

  Accompanying reading and punching equipment, the whole family is busy with online classes.

  The task of children attending online classes at home and supervising learning falls on parents. At the beginning of the epidemic, parents had to do logistics support such as equipment debugging and environmental layout for their children’s online classes while working in the cloud.

  It’s okay for parents not to go to work. When more and more enterprises return to work, some families with dual employees are facing the problem of unattended children. In some families, the elderly can help look after the children, but they can’t afford to accompany them all day. Grandma Shi, an old couple in Shanghai, recently accompanied her first-grade granddaughter to have online classes at home every day, from 9: 00 in the morning until 4: 30 in the afternoon.

  It is not only time that makes parents feel pressure, but also technical support at home. Online classes, computer equipment must be adjusted, right? You have to know how to fix a broken network, right? You have to be able to switch videos, right? Punching in on different online class platforms requires skillful use of various apps. Some netizens concluded that children need at least six support groups for online classes: technical support group, supervision and management group, service support group, camera group, contact and communication group and security support group, and none of them can be less.

  Psychologically, it’s a little difficult for parents to accompany them in reading. 

  And even if these are all in place, parents had better review the books that were thrown away before. Because I have to be an accompanying teacher, the tasks of supervising study and checking homework are much heavier than before. Chinese, mathematics, geography, history, and even art, music, sports, and handicrafts must keep up with the progress, otherwise they may be embarrassed in front of children. Moreover, many parents still have a hard day at work during the day. After work, there is still a lot of homework waiting to be done with their children. Some netizens shouted: This session of parents is too difficult!

  Xiong Bingqi, vice president of 21st Century Education Research Institute, said that it may be because our children study at home, so many times, the school directly gives parents the task of helping their children do their homework, and it seems to be justified. But in fact, what we can see is that parents have different educational levels. In fact, parents have their own affairs, so in this process, parents are actually overwhelmed.
