Narrator: Qiao Lei, a teacher from Tahe County, Harbin No.17 Middle School, who assisted in teaching in Daxing'anling, teaches and educates children. In my opinion, it is to use scientific professional skills and warm education to safeguard children's growth. My daily work is not so grand and bustling, but more ordinary day after day. Planting my own heart and watering the hearts of children is the joy of being a role model. In 2022, Heilongjiang Province will send outstanding cadres and talents to the border to assist in revitalizing the border and enriching the people. I arrived at Tahe No.1 Middle School in the Greater Khingan Mountains with four other teachers from the provincial capital of Harbin. There are a total of nine classes in three grades of the school, and the overall aging of teachers is severe. Every year, a large number of teachers retire, and new students cannot be recruited in a timely manner, resulting in many courses facing the dilemma of lacking professional teachers. Many teachers are teaching across disciplines. At first, I took on the teaching of mathematics for two graduating classes in junior high school, with 18 classes per week. After graduation, I also took on the teaching of two classes in seventh grade. Among the students I have taught, a simple and humorous girl named Xue Hui left a deep impression on me. After every class, she likes to gather around me and talk and laugh. In a unit test at the beginning of a school year, she only scored 6 out of 100 points. During that time, her smile decreased and she looked at me from a distance after class. I knew she was too embarrassed to approach me because of her grades. No child can be left behind. I took the initiative to talk to her, and I said to her, "Seeing this result, anyone would be very sad. I understand you, but I appreciate your idea of change more. To solve this problem, I am an expert, and with my support behind you, we will have changes. In the future, you should be prepared to endure hardship with me, okay?" "Well, don't worry, I am not afraid of hardship." We encouraged each other. Afterwards, I used my daily break time to help Xue Hui sort out the knowledge points; After class, use WeChat to help her closely follow up on her practice; Using the Feynman learning method, let her speak on her own and output ideas. Hard work pays off for those who have a heart. After a semester of hard work, Xue Hui's grades have increased from 6 points to 40 points, from 40 points to 76 points, and from last semester to over 80 points! The gratifying progress has made Xue Hui more confident, and she is also able to face every fluctuation in her grades more confidently. This year's Teacher's Day, I received heartwarming blessings from Xue Hui: Dear Teacher Qiao, thank you for always encouraging me. When I was in elementary school, my math grades were never good, but since I met you, I realized that math can still be learned this way. It's really fortunate to be your student. Xue Hui's progress is a microcosm of many students, and all I can do is to stimulate their intrinsic motivation through a continuous stream of encouragement and companionship that complements teaching and learning. I believe that every child has infinite possibilities. In teaching, I also realize that some children may not necessarily reach the level of excellence recognized by the public, but we can cultivate them to have the correct outlook on life, values, and basic learning qualities. Today's children will become tomorrow's parents, and the seeds of hope will be passed down through generations of progress. I think home school education will be a new topic that we need to delve into in our future teaching. In addition, I
