On June 23, Jimu Journalists learned from Wugang No. 3 Middle School that the papers written by Shang Zequn, Tian Yao, and Yu Zhendong of the school in the second year of high school (12) of the school "Wuhan Water Quality Evaluation Based on Lake Water Color" was The "National High School Mathematical Modeling (Application) Capability Activities" won the first prize in the country, which is also the only national first prize in Hubei Province. In this competition, more than 2,000 high school students from Beijing, Jiangsu, Hebei, and Guangdong participated.

It is reported that the topic selection of this event is harsh, and the age and knowledge of high school students must be reflected. The equipment cannot be excessively professional. Data collection and theoretical analysis must have strong operability ... Inspection, after half a year, the three students of Shangze, Tian Yao, and Yu Zhendong of Wugang No. 3 Middle School (12) made a satisfactory answer.

During the modeling stage, in order to collect data, the students ran to take pictures throughout the lakes of Wuhan, such as Yangchun Lake, and Nanhu in Donghu, Yangchun Lake, and Nanhu. Sometimes, in order to reduce the impact of light on the lake, they had to be cold and bitter for a long time. For the first time, the students realized that they couldn't stretch their fingers. The group member Shang Zequn said: "This time I can use the knowledge I have learned to systematically evaluate the water quality of Wuhan Lake. Maybe this work may not be perfect, but I am proud of myself."

After the early modeling ideas were finished, they checked the reference. Under the teacher's dial, the paper was modified several times by word to use rigorous academic vocabulary to express their research results and avoid spoken expression. In the final defense session, the students still did not let go of every detail and strived to be perfect. The opening whistle of "the judge is good", the group member Yu Zhendong practiced countless times. The group member Tian Yao said that after the model was built, in order to test the accuracy of the model, they took several groups of water samples for testing.

Han Qi, a math teacher and a group instructor of Wugang No. 3 Middle School, said: "Facing the difficulties of choosing topics and the difficulties of collecting data, the Shangze Group can support each other and do not bow their heads in encouragement; encourage each other. Wrong, find out and correct the problems in time. "The success of the topic is inseparable from the joint efforts of teachers and students. It is a picture of the team fighting side by side.

Award certificate

In the new curriculum standards, "Mathematics Modeling" is one of the six core literacy of mathematics disciplines, which has changed the status of mechanical learning in the middle and long -term existence of basic mathematics education in my country, allowing students to learn to use mathematical tools to solve practical problems, re -cognitive awareness The essence of mathematics. In December 2020, Wugang No. 3 Middle School successfully passed the recommendation and review, and was approved as a practical base for the Mathematical Modeling Education Center.
