In the past two days, "nucleic acid testing" has become the main word in the lives of Shanghainese. On Thursday, the children of Shanghai World Foreign Chinese Primary School received a special task from principal Zhang Yueying through the school's WeChat public account - "In nucleic acid testing, how to let everyone carry out nucleic acid testing at designated sampling points in accordance with the requirements of the staff to ensure that no household is missed and no one is left behind?" Students, you are welcome to participate in the collection of this plan, the plan can be in the form of text, can also be in the form of charts, of course, if you can use information means and tools, make a table, design a small program it is better! ”
The children's program soon flew to the school's email address. Among them, a "nucleic acid detection notifier" designed by le Mengchen, a boy in the third (2nd) class, is eye-catching.

Not long ago, when it was the turn of the community where Xiao Lejia was located to test for nucleic acid, it was already late at night. Because they did not know when the "big whites" would come, many residents went downstairs in advance to wait, and XiaoLe felt that this was both anxious and a little unsafe. He also saw that since it was almost time for rest, in order to ensure that every household could receive nucleic acid test notices, the volunteers of the neighborhood committee ran to every floor and every household, and made one notification after another.
"I think they're very, very hard, and I wonder if I can design a little program to help them." Le Mengchen said.
However, Mom and Dad are busy with work, and no one can help him. Xiao Le's father is the deputy leader of the fifth batch of "group-style" medical aid to Tibet task force in Shanghai and a doctor aiding Tibet in Ruijin Hospital affiliated to Shanghai Jiao Tong University, Xiao Le can only tell stories through video chat with "Father Yun" since the first grade; his mother works in the laboratory of Shanghai First Maternal and Infant Health Hospital, the epidemic has returned, Xiao Le's mother and colleagues have a sharp increase in workload, "six to six" every day, and the pace of work has not stopped.
The boy, who usually had a lot of whimsical ideas in his head, took the inventory out of the baby box and began to think of a way. The number of babies is limited, and they are all hoarded by him on weekdays - to "When the school was in micro: bit programming class, the teacher gave us a motherboard, I joined the programming school team, the teacher sent a motherboard, and there was a buzzer in the box, so I thought I could use them!" Xiaole envisioned that if the volunteers had a transmitter in their hands and each household had a receiver with a buzzer, as long as the transmitter and receiver used the same wireless group, they could communicate with each other! A building uses a password, and volunteers can notify a building with a single click, just like turning on a TV remote control.
The small program is not complicated, in addition to forgetting to set the receiver and transmitter in the same wireless group at the beginning, there was a "bug", Le Mengchen spent two hours to get it done, and also took a video of the explanation. When my mother came back from work, she was really surprised and told my father who was far away in Tibet. "Daddy Cloud" helped the little guy re-edit the video as an encouragement.
Parents let go and encourage their children to think big
"During the epidemic, my focus is not on his achievements, but on such an experience of growing up independently, which is precious to children." Le's mother told reporters that during the last epidemic, Xiaole was only in the first grade, and there were still some hands and feet; but this time, the child obviously grew up - only his grandmother was at home with him during the day, xiaole not only set several alarm clocks on his iPad, reminding the start time of the live class, and the "looking time" of his eyes to rest; printing, handing in homework and other things, all came by himself. Le's mother felt, "Maybe because we have to 'let go', the child has more possibilities for growth." ”
On the other end of the phone, Xiao Le couldn't wait to tell reporters that on the days without his parents, he alone made up how strange little things to drink, such as "anti-head long buzzer", "sports fan", "old money profit and loss calculator", etc., as well as the "password memory" that was popular with his mother.
In fact, Xiao Le also said that his small device is still only a very preliminary idea, and problems such as remote control distance and accuracy need to be consulted by the teacher. But in the view of principal Zhang Yueying, the important thing about this small task of children may not be the result, but a passion for paying attention to life and society. Two or three days have passed, and some children have handed in mind maps, some have handed in text and pictures, and some have just handed over a simple word document. Regardless of the form, in this process, learn how to use "project-based" thinking, master the methods and paths to find problems and solve problems, this is the harvest.
