The importance of language in mathematics classrooms

"Infectious Disease Model and Solving Equations" by mathematics teacher Yang Ye

The second lesson of the class is "Infectious Disease Model and Solving Equations" by mathematics teacher Yang Ye. Her scenario introduction is impressive: pneumonia caused by the new coronavirus affects the hearts of people across the country, and influenza often occurs in spring and autumn. How to use mathematics to interpret the spread of infectious diseases? She gave an example: one person contracted an infectious disease, and after two rounds of infection, 121 people became sick. On average, how many people did one person infect in each round of infection? Through lively discussions and explorations, students learned the mathematical model of infectious disease transmission, realized the importance of using mathematical language to describe and solve practical problems, and enhanced their knowledge and understanding of the importance of "epidemic prevention."

The third lesson is "The Story of Photos" by Chinese teacher Zhao Mengyun. After Teacher Zhao played a hand-made flash mob video for the resumption of online classes to "warm up", he showed the students three classic photos. One photo shows the East Branch of Wuhan University People's Hospital during the epidemic. On the way to escorting a patient for a CT scan, doctor Liu Kai stopped to let the 87-year-old man, who had been lying in bed for more than a month, enjoy a long-lost sunset; The photo is of a two-year-old boy named Ze Ze who was about to be discharged from Shaoxing Central Hospital. He suddenly bent down and bowed to the head nurse Cao Lingling. The small town of Llandudno in North Wales, England, welcomed a special group of "visitors". A group of about 120 wild goats strutted around the empty streets. As a photography enthusiast, Teacher Zhao vividly told the stories behind the three photos. She told everyone that a good photo, a photo that can truly touch people's hearts, is often emotional and has life value. Later, teachers and students freely shared the most impressive photos taken during the epidemic and told the stories behind them. They introduced their experience of working without sleep for 8 hours to make a 3-minute video to Wenbo students; Lu Siyi showed how to stay at home Flowers taken during the online class at grandma's house; classmate Zhu Yuhan described the ideological baptism she experienced after reading Yu Hua's "To Live"... Finally, Teacher Zhao gave the students a small surprise. She asked her colleagues who were attending the class I took a group photo of myself and my classmates, printed it on the spot with a photo printer and sent it to everyone, asking each student to write down their wishes for the new semester and new life behind the photo.

The fourth class was taught by the head teacher and English teacher Zeng Li. Teacher Zeng let the children be the protagonists and was presided over by two class cadres. This class includes the study of famous quotes, poetry recitation, story telling, performance, discussion and exchange, swearing-in, etc. The content is rich and colorful. With the witness of the whole class and the encouragement of Teacher Zeng, the students boldly read out their dreams and solemnly posted the prepared dream cards on the dream wall. Some children want to be a sunny and gentle girl, some children hope to be admitted to Wuhan Iron and Steel No. 3 Middle School and then go to Wuhan University to see cherry blossoms, and some children hope to have a child as bright as summer flowers... The epidemic has just passed and the third grade of junior high school is approaching. The added pressure of the high school entrance examination made the children's oath-taking ceremony full of ceremony and particularly encouraging.

Huang Hanming, the principal of Baiyushan Middle School, said that the vast majority of the school’s students are children of migrant workers in the city, and the learning effect of online classes is far from expected. The epidemic ideological and political course is also a knowledge connection course. No child will be left behind in future work.
