The math teacher draws beautiful pictures with ＂function curve＂. It’s so beautiful! Students are reluctant to clean the blackboard.
Teacher Zhu is instructing students to learn mathematics.
Teacher Zhu’s paintings use parabola, hyperbola, ellipse, cubic parabola and other functional curves to show the beauty of smooth and soft curves.
Mathematics in senior high schools and universities always gives people the impression that it is abstract and boring and difficult to learn, and many students are afraid of difficulties in mathematics classes. Yesterday, in the math class of Yangzhou Higher Vocational and Technical School, the reporter of Yangzi Evening News saw the clever and beautiful picture drawn by the math teacher with "function curve" on the blackboard, which was unforgettable. In class, the teacher painted brilliantly and spoke vividly, and the students listened and remembered with great care. Do you envy such a "fancy math class"?
He is a "painter" delayed by mathematics.
A piece of chalk painting drawn by "mathematical language"
Although there are only a few strokes, they are vivid and vivid, just like works of art
Zhu Zhonghai, director of the Basic Education Department of Yangzhou Higher Vocational and Technical School, is a math teacher. At the age of 57, he has been teaching mathematics for 35 years. Yangzi Evening News reporter found Mr. Zhu yesterday and saw the chalk paintings he "created" last year and this year. The reason why we should use the formal word "creation" is because these chalk paintings in the eyes of reporters are vivid and vivid, just like works of art, although there are only a few strokes. Without a certain skill, it can’t be done just by some mathematical curves.
The Yangzi Evening News reporter noticed that these chalk paintings drawn in "mathematical language" include slender women, elderly people, naughty children and naughty kittens. From the action point of view, some are looking at the distance, some are enjoying flowers, some are dancing, some are playing the piano, some are picking, some are playing ball games, and some are observing bugs; From the color point of view, some have only one color, white or pink, and some have two colors, but no more than three colors. Whether it is one color or a limited number of two or three colors, the works are vivid and vivid, and a few gentle curves are combined slightly, which gives the works vitality and shows the author’s skillful and superb painting skills. In the corner of each painting, some of them are written with the titles of "childlike interest", "picking", "returning from the storm" and "sports beauty". Each painting is signed "Xiaohai", and the running script font is as smooth and agile as the picture. Teacher Zhu, who is nearly sixty years old, calls himself "little", which reflects his frank and modest character and attitude towards work.
"Teacher Zhu’s math class is nice, interesting and really beautiful! My classmates and I didn’t expect that the boring and difficult mathematical figures, those parabolas and function curves, came to Teacher Zhu, and when they were combined and matched, they were all a painting, and we were all attracted by him. " A classmate told the Yangzi Evening News reporter that when Mr. Zhu was in class, the whole blackboard was a blackboard newspaper with different fonts, large and small intervals, different colors and vivid illustrations. After class, the students in charge of health are reluctant to erase the blackboard. It’s really beautiful.
Teacher Zhu told the Yangzi Evening News reporter that he had taught high school mathematics, secondary vocational mathematics and higher vocational mathematics. "I’ve been thinking. In math class, can you make students’ eyes light up, calm their hearts and focus their attention on the blackboard? " Teacher Zhu told the Yangzi Evening News reporter that teachers’ professional ability is housekeeping skills, and their basic skills are not only "facade" but also core competitiveness. Mainly reflected in the calligraphy, pen, chalk and "three words and two words (painting)" in speech and painting, this is not achieved overnight, and it needs long-term tempering and accumulation. I practice calligraphy and painting every day and make progress every day.
"When I was teaching functions last year, when I talked about curves and equations, I thought that the beauty in life is everywhere, and the gentle curves in life are vivid and smart. After pondering and thinking, I created a series of chalk sketches" Dancing Functions ". Some are painted on the spot in class, some are painted in advance, and each curve can be defined, beautiful and related. The key is how to use them well and how to combine them so that they can present the most beautiful visual effect in the most suitable position. The students’ emotions were suddenly mobilized and attracted by every beautifully conceived function curve. " Recalling the "function curve drawing", Teacher Zhu said excitedly.
Painting depends entirely on self-study
Attract students with the "unique skills of board painting" with the integration of arts and sciences
"No matter which class I talk about, I should make students feel the charm of mathematics according to the culture behind the theme of the course and the related math stories. I have written a book" The Starry Sky of Mathematics "from my decades of teaching experience, which has now been published."
For Mr. Zhu, chalk painting is also gradual. The students said that he had a unique skill in drawing "unique skills" with chalk, and he could draw very, very round without compasses. Several times after class, the students verified it with compasses, and the results showed that it was almost the same, so the students all took it. "Of course, I didn’t draw a circle at first, but I painted a lot. I painted with my heart and accumulated it to a certain extent, and it became." Teacher Zhu told the Yangzi Evening News reporter.
"I use appropriate teaching methods and a blend of arts and sciences to teach. In addition to mathematics, I like literature and art very much, especially in vocational schools. I try my best to tell and interpret it in liberal arts during the teaching process. The examples I give are all examples from my classmates’ familiar life, combined with the students’ majors and what majors they study. What kind of relevant examples are given? " In recent years, Mr. Zhu has published nearly 100 essays, poems and prose poems. He doesn’t want to make any achievements in literature and art, but wants to improve his literary and artistic accomplishment and increase the thickness of his comprehensive quality, so as to promote himself to teach mathematics better, make his math class more agile and be accepted and liked by students. The Yangzi Evening News reporter learned that after Mr. Zhu created the painting "Dancing Function", he successively created a series of works such as "Community Style", "Rhythm on the Blackboard" and "Beauty of Points, Lines and Surfaces", totaling more than 200 paintings.
"Mathematics learning is abstract and boring. I decorate the classroom with sketches to make students’ eyes light up." Teacher Zhu told the Yangzi Evening News reporter, "I don’t specialize in painting, but because of my love and persistence, I am confident that I can draw well and influence my students."
He is like this in the eyes of his colleagues.
I can write poetry and prose, understand photography and have feelings.
"He has one share of magic to seize students."
"Teacher Zhu is a senior math teacher in our school and a middle-level cadre. He is recognized as a teacher with humanistic feelings in our school." Teacher Zhu’s colleague told the Yangzi Evening News reporter that teacher Zhu has many talents, not only teaching mathematics well, but also writing poetry, prose and photography, which is very popular among teachers and students. Mr. Zhu has won the title of National Excellent Teacher and the National Excellent Professor Medal. He is a young and middle-aged expert with outstanding achievements and the winner of the first batch of national backbone teachers in the "333 Project" in Jiangsu Province. Judging from the years of working and getting along with Mr. Zhu, he is well-deserved and worthy of these achievements and honors.
"His image and temperament are no different from everyone else’s, but there seems to be some magic in him that can catch students at once." A young teacher told the Yangzi Evening News reporter that the school has requirements for information-based teaching, and many young teachers may rely too much on PPT. After reading Mr. Zhu’s class, they were really inspired. Mr. Zhu, an uncle, used mathematical curves to draw beautiful and fashionable paintings, so it is no wonder that students like it so much. In fact, PPT teaching and classroom blackboard writing and blackboard drawing are not contradictory. If they are organically combined, the classroom efficiency will be higher.
He, deeply confided in his heart.
"I think PPT teaching should be moderate now. As a teacher, the essence of some teaching traditions can’t be lost, such as writing on the blackboard. In my opinion, writing on the blackboard on the spot, calculating and reasoning on the blackboard, and letting students learn and understand the reasoning process intuitively will definitely leave a deep impression. I also want to take my own practical actions, which I have persisted in for many years ‘ Old ox ’ The habit of writing on the blackboard sets an example for young teachers and influences them. " Teacher Zhu said that his teaching pursuit is to stand well in the classroom and make it full of vitality. Instead of filling the students’ baskets, we light the lights and use one soul to wake up another. "No job is easy to do. Instead of complaining uselessly and needlessly, it is better to calm down and do your own job in a down-to-earth manner. I don’t expect what I do to be brilliant, but at least I can make myself progress and get better gradually." (Correspondent Grace Wai Wong Yangzi Evening News/Zi Niu News reporter Yong Chen)
