Zhang Jiantao, a science teacher from rural Henan, has the "superpower" of using inconspicuous materials such as plastic bottles, rubber bands, straws, etc., to make very interesting experiments in the eyes of children. In a rural primary school with limited materials, Zhang Jiantao tried his best to turn waste into treasure and plant the seeds of science for children. What is he busy with this winter vacation? Let's take a look at the ** Radio and Television Station CCTV report with Education Xiaowei
When I met Zhang Jiantao, he was rushing from his hometown in Henan to Suzhou, thousands of miles away, to participate in the winter vacation empowerment training for science teachers in the eastern, central and western regions. It was the first time to go to other provinces to participate in the training, and Mr. Zhang also experienced the feeling of wearing an experimental white coat for the first time.
During the week, teachers from different regions communicated with each other, systematically learned the knowledge of life sciences, and shared their teaching experience. Although there are no ready-made science teaching aids, Zhang Jiantao still showed everyone the scientific experiment of turning waste into treasure. Plastic bottles, rubber bands, straws, and inconspicuous materials made the classroom boil, and some children looked through the cracks in the door.
In this training, Mr. Zhang also gained knowledge about life sciences, and also brought back 50 sets of DNA science teaching aids to the township school in his hometown, and he plans to start teaching in the new semester.
The reporter followed Mr. Zhang to the place where he developed interesting scientific experiments. In the laboratory of the No. 1 Primary School in Zhangguangmiao Town, Gushi County, Henan Province, carbonated drink bottles and PVC water pipes. They are all Mr. Zhang's "treasures". Zhang Jiantao, who can turn waste into treasure and play science with children, was admitted to the rural teacher post three years ago and was assigned to teach mathematics.
With the popularization of science education, his township school built a multi-purpose laboratory, and Zhang Jiantao applied to become a science teacher. Although he did not come from a professional background, Zhang Jiantao studied in online public classes, where he made garbage cans fly over roofs, made ping-pong balls levitate in the air, and sent drink bottles into the sky.
Eighty percent of the children in Zhang Jiantao's township primary school are left-behind children. This winter vacation, Mr. Zhang held a "science parent-child camp" in the school. The family after a long absence, in the fun science experiment, shortened the distance.
"Water Rocket" is the children's favorite science experiment, and this is also the finale experiment in the parent-child camp.
Ni Na, a parent of the student: The children are very curious about everything now, especially the national rocket, and they are very excited and want to know about it.
The water rocket "soared into the sky, and the sense of science and technology was bursting. But what everyone doesn't know is that Mr. Zhang failed more than 150 times to make "water rockets" with drink bottles.
Zhang Jiantao, science teacher at the first primary school in Zhangguangmiao Town, Gushi County, Henan Province: Every time you fail, you have to record it, you have to take pictures to see it, and slowly see which position it fails, I have calculated for myself, I have to launch 3 to 5 times at noon every day, and the children will surround you for experiments. It's like your own little brother and sister, they surround you, and after a long time, it feels like there is a meeting with their hearts, and you can feel that children like these things, and they need these things.
In the face of repeated failures, 40 children retrieved 253 drink bottles, which provided materials for the "launch module" of the water rocket. Zhang Jiantao said: Learning to persevere in the face of failure is an important lesson in science education.
Xiong Lei, a parent of a student: Children often make a small invention of mineral water bottles and some things that they don't feel to be used at home, and there are many failures, but I think the "seeds" of science have indeed been planted in children's hearts.
Before the winter vacation, Ms. Zhang asked the children to talk about their dreams. Some children speak boldly, while others silently recite in their hearts. Teacher Zhang asked the children who did not speak to write down their dreams and paste them on water rockets.
Zhang Jiantao, science teacher at the No. 1 Primary School in Zhangguangmiao Town, Gushi County, Henan Province: I want to know their dreams, and I found that many children want to become scientists and astronauts. And what I am most pleased about is that some students want to become a science teacher, a science teacher like Ms. Zhang.
In Ms. Zhang's view, science education affects the future of children and the future of the country. Last semester, Zhang Jiantao was given a new identity as one of the first science popularization experts in Xinyang City, and he was also the only expert from the countryside.
Zhang Jiantao, science teacher at the No. 1 Primary School in Zhangguangmiao Town, Gushi County, Henan Province: I think my direction is clearer, and my energy will be more concentrated. I also have the confidence to take this road further and wider.
During this winter vacation, Mr. Zhang packed a box full of experimental tools and props to take home to prepare for the experimental class in the next semester. The reporter returned to this old house in the countryside with him and found that it was completely a "dream space" for scientific experiments. In the process of experimental production, Mr. Zhang also used ** to record every improvement and summary of experience. During the winter vacation, he discussed with science teachers from other places in the cloud to share more experiences.
In Zhang Jiantao's view, no matter what environment you are in, you should boldly pursue your dreams. He named the laboratory of this township primary school: Eagle Science and Technology Museum, which is about to usher in the new spring semester, and his greatest wish is to bring more children into the spring of science.
Zhang Jiantao, science teacher of the first primary school in Zhangguangmiao Town, Gushi County, Henan Province: We feel that we have been making progress and need to improve, so we named a Young Eagle Science and Technology Museum. (CCTV reporter Liang Zhengzheng, horsepower).
