Class photos
The third class is a photo story of Chinese teacher Zhao Mengyun. After playing the flash video "Warm-up" made by Mr. Zhao, he showed the students three classic photos. One photo is the East Hospital of Wuhan University People's Hospital during the epidemic. On the way to escort the patient for CT, the doctor Liu Kai stopped specially to let the 87-year-old man who had been in bed for more than a month enjoy a long-lost sunset. A photo was taken in Shaoxing Central Hospital. Ze Ze, a two-year-old boy who is about to leave the hospital, suddenly bent down and bowed to the head nurse Cao Lingling to thank him. Cao Lingling immediately bowed back and thanked her. A photo shows a group of special "tourists" in Landno, a small town in North Wales, England. About 65,438+020 wild goats swaggered along the empty street. As a photography enthusiast, Teacher Zhao vividly tells the story behind three photos. She told everyone that a good photo is often emotional and valuable in life. Later, teachers and students freely shared the most impressive photos taken during the epidemic, told the stories behind them, and introduced their experiences of making three-minute videos for eight hours without sleep. Lu Siyi showed the flowers taken during the online class at her grandmother's house. Zhu Yuhan talked about the ideological baptism he experienced when he read Yu Hua's Living ... Finally, Mr. Zhao gave the students a little surprise. She asked her classmates to take a photo of herself and her classmates, print it out on the spot with a photo printer and send it to everyone, so that each classmate could write down his wishes for a new life in the new semester on the back of the photo.
The fourth class is taught by the head teacher and English teacher, Professor Zeng Li. Ceng Laoshi lets the children play the leading role and is presided over by two class cadres. This course includes learning famous sayings, poetry recitation, story telling, performance, discussion and exchange, oath and so on. , its content is rich and colorful. With the witness of the whole class and the encouragement of Ceng Laoshi, 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 are looking forward to being admitted to WISCO No.3 Middle School and then going to Wuda to see cherry blossoms, and some children want to be as brilliant as summer flowers ... The epidemic situation just passed and the pressure of the senior high school entrance examination in grade three are superimposed, which makes the children's oath full of ritual and particularly inspiring.
Huang Hanming, principal of Bai Yushan Middle School, said that the vast majority of students in this school are children of migrant workers, and the learning effect of online courses is somewhat different from expectations. "Teachers strive to turn the first class of the school into an anti-epidemic ideological and political class and a knowledge connection class, and never let a child fall behind in future work."
