Inquiry Learning: Summary Report on "The Application of Mathematics in Life"
I. Research background:
Mathematics is a very useful subject. Since the day when human beings appeared on the earth, people have gradually gained a profound understanding of mathematics while understanding and transforming the world. As early as ancient times, there was a legend that primitive people "dabbled in counting" and "knotting a rope". It can be seen that in some early ancient civilized societies, the beginning and bud of mathematics have been produced. Before mathematics appeared in Babylon and Egypt around 3000 BC, human beings did not make more progress in mathematics, but after the appearance of ancient Greek scholars from 600 BC to 300 BC, mathematics began to enter the big stage of human development history as an organized, independent and rational discipline.
Nowadays, mathematical knowledge and ideas are widely used in industrial and agricultural production and people's daily life. For example, after shopping, people should keep an account for year-end statistical inquiry; Go to the bank to handle savings business; Check the water and electricity charges of each household. These facilitate the use of knowledge of arithmetic and statistics. In addition, the "push-pull automatic telescopic door" at the entrance of the community and government compound; Smooth connection between straight runway and curved runway in sports field; Calculation of the height of the building whose bottom cannot be closed: determination of the starting point of two-way operation of the tunnel; The design of folding fan and golden section is the property of straight line in plane geometry, and it is about the application of solving right triangle knowledge.
It can be seen that throughout the ages, human society has been developing and progressing in the process of constantly understanding and exploring mathematics. Mathematics has played a decisive role in the development of human civilization.
Second, the purpose and significance of the study:
1. Feel mathematics and appreciate its value. The research study of "the application of mathematics in life" allows students to collect and develop materials in their own lives, feel the close relationship between mathematics and our real life, let everyone feel the coexistence of life and mathematics, and experience the value of mathematics itself.
2. Understand mathematics and sublimate your thoughts. The research study of "the application of mathematics in life" allows students to experience the re-creation of knowledge, the formation process of knowledge, form their own effective knowledge and further sublimate their own thoughts.
3. Can use mathematics. The research study of "the application of mathematics in life" allows you to learn to apply mathematics and achieve the ultimate goal of directly creating value for society.
Third, the research process
1. Set up a research group (week 12 of the first semester).
2. Opening the topic (week 13 of the first semester). Organize students to give a report on the opening of the project, and introduce the background, conception, demonstration and implementation plan of the project.
3. research. (week 14 of the first semester to week 15 of the second semester) Under the guidance of teachers, students in this project team actively participated in the exploration, research and calculation of the topic "Application of Mathematics in Life" through math textbooks and chemical materials in their spare time. Some students verified the research results through experiments, which reflected their rigorous scientific attitude. Under the guidance of the teacher, I will write a small paper about the research results and experience of "the application of mathematics in life".
Fourth, topic: the research results of "Application of Mathematics in Life".
Essay: Application of inequality, sequence and function in life (see attachment 1).
Verb (short for verb) experience
Through this research study, we have learned a lot and learned a lot. In the past, learning mathematics was generally a theory, lacking the connection with practice, and I didn't know how to use it after learning it. The biggest gain of this research study is not to get any results, but to cultivate a habit of thinking, a habit of turning phenomena in real life into problems and conducting research. When we write on the blackboard and break the chalk with too much force, have you ever thought about how long the chalk is? When we make a phone call, can we think of this as a "function model" to find out the function of telephone charges and time? Even when we play games, can we use discrete and probabilistic ideas? After you can't help laughing, you will find that these problems actually come from our lives, but their combination and extension may involve the forefront of today's science.
In addition, I feel that my knowledge is still not wide enough. For example, the teacher gave us many valuable questions. Because of our shallow knowledge, we finally chose "the application of function, inequality and sequence in life" to explore and study. It is ok to calculate the problem data, but when looking for the law of calculating the data, we encountered difficulties and the teacher gave us guidance. If you study at ordinary times, pay more attention to the combination of theory and practice, apply what you have learned and start research-based learning, you will be more successful.
After all, research study is a collective project, which not only cultivates our spirit of cooperation, but also cultivates the spirit of unity, friendship, mutual assistance and cooperation. Therefore, after forming a group, our group often discusses topics together, and then carries out computational research when the discussion is mature. As the saying goes, three heads are better than one Zhuge Liang. If we make something together, we will have a sense of accomplishment, which is also the fun that research-based learning brings us.
Research-based learning cultivates innovative spirit and the ability to solve problems quickly. Participating in the research study group also gives us a simple understanding of scientific research work. The rigor and boldness required by scientific work are fully reflected in such activities. It makes us realize the hardship of scientific research work, which will have a positive effect and far-reaching influence on our future study and work.
