"The transmission model of the novel coronavirus is a mathematical model that advances from a simple exponential growth layer by layer to a complex one. From a mathematical point of view, China's epidemic prevention measures are scientific and rigorous..."In class, the problems in life become Li Bingzhao's vivid teaching cases。

Mathematics is the foundation of natural science, and major innovations cannot be achieved without the support of mathematics。In 2001, Li Bingzhao graduated from the Department of Mathematics of Beijing Institute of Technology and stayed to teach there. He successively undertook the teaching work of courses such as "University Mathematics", "Mathematical Modeling", "Mathematical Experiments" and "Mathematical Methods in Information Analysis"。After teaching for more than 20 years, Li Bingzhao, a mathematics teacher, has overcome the "abstract gate", let students learn mathematics well, and become innovative talents with profound mathematical foundation。

"Mathematical Experiments", "Looking at the world through Mathematics" pay attention to the foundation of mathematics, "Mathematical modeling contest guidance", "optimization theory and method", "SPSS statistical analysis" help students participate in mathematical modeling, "Mathematical model" focuses on mathematical principle derivation..."Talking about a mathematics class, Li Bingzhao is like a gem。

After years of deep education in college mathematics teaching, Li Bingzhao gradually found that practical and innovative courses such as mathematical experiments and mathematical modeling can help students solve practical problems with abstract mathematical knowledge, and promote students' mathematical thinking and innovation ability in the integration of theory and practice。

"The utility of just one or two courses is too small，Let mathematics knowledge "come alive"，And make classes' swarm '!"To improve students' ability to use mathematics，Achieve a deep integration of theory and practice，Li Bingzhao led the reconstruction of the mathematics practice curriculum system with the cultivation of students' practical innovation ability as the core，After years of deep ploughing，A clear architecture and a clear teaching focus，A curriculum system that can help students master abstract mathematics knowledge effectively，Set up in the Beijing Institute of Technology。

"Teacher Li's unique insight, the profound mathematical principles of the explanation of easy to understand, greatly inspired our enthusiasm for mathematics learning.。Teachers are great!"There are plenty of student comments like this on college MOOC platforms。

After reshaping the innovative curriculum system of mathematics practice, Li Bingzhao did not stop his exploration。Since 2016, he has led the team to plan the construction of practical online teaching resources such as mathematical modeling and mathematical experiments。"Mr. Li is from Shandong, with a generous personality and no reservations about the help and guidance of the team teachers.。It is also under his influence and drive that our team focused on the mathematics experiment curriculum system and put forward many innovative ideas and methods。"Mathematical modeling teaching team young teacher Room Yongfei introduced。

2017年，"Mathematical Experiment MOOC" was launched on the Love Course platform;The year 2020，"Mathematical Modeling MOOC", "Seeing the World Through Mathematics MOOC" launched;Since 2017，"Mathematical experiment Course", "Mathematical Modeling advanced", "Mathematical modeling excellent paper compilation" and other supporting textbooks have been published...One course followed the other，Complementary textbooks are published and distributed，It indicates that the curriculum system of mathematics practice innovation in BEIT has begun to take shape。

In addition to innovative curriculum system，Li Bingzhao has also worked hard to improve the quality of classroom teaching，The research teaching mode of discussion and question is put forward，And summed up the "three combination" principle in mathematical modeling teaching，It is to combine classical mathematical problems with real hot spots, case introduction with theory explanation, experiment teaching in class with extracurricular mathematical contest in modeling。

0.13%!Cultivate "gold medal" talents

Li Bingzhao answers questions for students in class

Tens of thousands of teams worldwide, two years, two grand prizes, probability 0.13%！

Model, solve, verify, write papers in a limited time, and compete with thousands of teams around the world...This is the "originator of mathematical Contest in Modeling" - the American College student Mathematical Contest in Modeling。In 2020, Li Bingzhao guided undergraduate students Yu Dingyi, Ren Weiming and Wang Sichun to win the highest award of the competition - Outstanding Winners, refreshing the best performance of BTU in the competition。In 2021, Pan Jiong, Chen Longfei and Zhang Leyi, all undergraduates under the guidance of Wang Hongzhou, a teacher in Li Bingzhao's team, won the top prize in the world's top mathematical modeling competition for college students again, and the winning rate in this competition was only 0.Thirteen percent of the tournaments were successfully defended。

"The scientific and effective training and guidance model and the training base with a strong innovative atmosphere are the booster for us to win the highest podium in the mathematical modeling contest, and the careful guidance of Li Bingzhao is a beacon for us to travel the world of mathematical modeling.。Yu Dingyi, a 2017 undergraduate from the College of Mathematics and the winner of the Grand prize of the United States Mathematical Contest in Modeling, said with deep feelings。

In recent years, Li Bingzhao has guided graduate students to win 8 awards such as the National Graduate Mathematical Contest in Modeling, the "Sharing Cup" Innovation Competition of Science and Technology Resource Sharing Service for College students, and the Innovation Scholarship of the Ministry of Industry and Information Technology, and has guided graduate students and undergraduates to publish more than 10 academic papers。Every year, the team organized nearly 2,000 people to participate in various mathematical contests in modeling at all levels, and guided undergraduates to win more than 1,000 awards in various mathematical contests in modeling。

Behind the repeated awards in the mathematical modeling contest and the explosion of innovative talents, Li Bingzhao and his team of teachers have devoted themselves to exploring and innovating for many years。In order to let more students feel the charm of mathematics and expand the influence of mathematical modeling，Li Bingzhao's team reorganized the "whole chain" of mathematical modeling innovation activities，This paper puts forward a new model of tutoring in mathematical contest in modeling, which has the spiraling pattern of "coaching, training, competition, coaching, competition, research and innovation"，This achievement also won the first prize of the 2013 Beijing Higher Education Teaching Achievement Award。

"To promote the sustainable development of mathematical modeling, we must not only stimulate students' enthusiasm for innovation, but also have projects suitable for students to participate in.。Under the leadership of Teacher Li，Since 2013, we have been exploring the integration and collaboration between scientific research projects and the cultivation of innovative talents in mathematics practice，On the one hand，Encourage teachers to transform the scientific research projects they undertake into innovative mathematical experiments;On the other hand，Interested students are also encouraged to actively participate in the research topics of the team teachers，Generate new research results。"Room Yunfei talk。

Li Bingzhao's team gave full play to the role of the mathematical experiment center, and developed a mathematical experiment innovation platform open to undergraduate and graduate students in the university。The platform brings together innovative topics proposed by the teachers in the team，At the same time, it combines the research projects undertaken by the Beijing Key Laboratory of Mathematical Representation Analysis and Application of Complex Information and the Key Laboratory of Mathematical Theory and Computing Industry and Information Technology of the Ministry of Information Security，The college students mathematical modeling innovation project "reservoir" was constructed.，Provide continuous project support and intellectual guarantee for students to participate in innovative activities。

At present, the mathematical experimental innovation platform has designed more than 10 mathematical practice topics, such as the model-based auto insurance pricing model, the data analysis and processing model of photovoltaic power station, the prediction and estimation model of oil water content, the comprehensive service evaluation model of national fitness, and the mathematical model in signal processing。

As the initiator of the National Mathematical Contest in Modeling for College students and one of the first four mainland universities to participate in the United States Mathematical Contest in Modeling for College students，Under the efforts of many mathematics teachers represented by Li Bingzhao，Beijing Institute of Technology mathematical modeling teaching research has been in the forefront of the country，It has formed a distinctive model of mathematical modeling teaching and counseling。

"Strict Teacher" is also a "warm man"

Li Bingzhao took a photo with the graduates

"I was eager to carry out research, but I lacked understanding of the professional direction, and I did not know where to start, and the whole person was in a confused and anxious state.。Teacher Li was very careful. After observing my state, he took the initiative to communicate and talk with me for many times, and helped me choose the research direction according to my situation, which laid the foundation for my subsequent rapid scientific research。Under the careful guidance and care of his mentor Li Bingzhao, Gao Wenbiao, a doctoral student of 2018, "resisted" anxiety, and grew academic day by day, with fruitful results, and won a series of honors such as academic scholarship and excellent doctoral thesis seedling Fund of Beijing Polytechnic。

In the first impression of the students, Li Bingzhao is a "strict teacher", but with the increase of contact, Li teacher is a "warm man"。In Li Bingzhao's view, moral education should not only pay attention to students' learning, but also focus on the comprehensive development of students, he encourages students to actively participate in work and activities other than scientific research to exercise comprehensive ability, and take good care of students in life。

Gao Wenbiao, who first came to the research group, is introverted and unwilling to contact and communicate with people。Li Bingzhao encouraged him to be a teaching assistant for "Mathematical Analysis" and "linear Algebra", and arranged for him to give a report at an academic conference. After several years of exercise, Gao Wenbiao not only improved his academic ability, expanded his professional knowledge, and greatly enhanced his interpersonal communication。Because of the epidemic, Gao Wenbiao has not been able to go home for the New Year for three consecutive years, Li Bingzhao learned that not only vacated his office to give him temporary study space, but also bought a lot of snacks to ease his homesickness。

"Mr. Li is humorous, rigorous and serious, meticulous in his work and attentive to his students。As the instructor of the mathematical modeling team, Ms. Li will give detailed guidance to the whole process from pre-competition preparation, guidance and training to competition registration and payment process。Through three consecutive participation in the national (United States) mathematical Contest in modeling, undergraduate Yu Dingyi also forged a deep friendship with Li Bingzhao。

Noble quality, warm character, exquisite scientific research ability, Li Bingzhao moistens things silently, love life like son。Since his teaching career, Li Bingzhao has trained 52 master students, 11 doctoral students, and guided and trained more than 200 award-winning students such as mathematical contests in modeling。

"As the country pays more and more attention to basic disciplines，Mathematics discipline ushered in the history of the best moment and development opportunities，We need to innovate from the perspective of mathematical practice，Based on national strategic needs，Stimulate students' interest and ambition in learning mathematics and applied mathematics，To cultivate a group of top-notch innovative talents with outstanding mathematical ability for the Party and the country。In the future, Li Bingzhao will lead the team to build a higher level and more professional mathematical practice innovation system, constantly improve the ability and level of education, and escort the students of Beijing Institute of Technology to have a deeper mathematical foundation and a more prominent innovation ability。
