Math diary's content is rich and colorful. He can write about the review and reflection on the study of mathematics, the application of mathematics in life, the mathematical phenomena he saw, the mathematical problems he thought of, the stories related to mathematics, and the mathematical knowledge he saw in books, including interesting mathematics, mathematical stories, mathematical jokes, introduction to mathematicians, and how to play mathematical games. You can also write your own answer to a math problem, your own experience in learning math, and your own learning methods. In a word, math diary's content is very extensive, and its form is also eclectic. But when writing, you must pay attention to your own ideas, be novel, and keep the words concise and clear, preferably about 200 words.
Math diary can express his ideas through words, mathematical symbols, graphics and drawings, and record the process of his thinking and discovery. It is a good math diary.
When writing about math diary, we should also pay attention to collecting mathematical information. A large amount of information provides students with a broad learning space. Pay attention to observation at ordinary times and record the mathematical information you see. You can also collect math information by going to the library and participating in various activities, and put the collected graphic materials into your math bag to enrich your math knowledge.
For example, after learning the multiplication distribution rate, a student wrote: Today, after learning the multiplication distribution rate, he learned that the letter expression of the formula is: a×(b+c)=a×b+a×c, and he also knew how to apply it in life. That day, my mother and I went shopping. My mother bought three pounds of tomatoes and three pounds of zucchini. When my mother asked about the price, I calculated the total price 12 yuan. At this time, the aunt who sells vegetables said, how do you calculate so fast? I said, "I used the multiplicative distribution rate!" " My mother looked at me doubtfully, wondering what was going on. I said, "I'll tell you about it at home." So we went home happily.
The child used to write badly in math diary, but he always wrote something that had little to do with mathematics. After learning the method of writing math diary, I not only know what to write, but also apply the learned mathematical knowledge to real life, and gradually develop good habits.
Second, stimulate students' interest in learning and make them happy to write about math diary.
Interest is a person's inclination to something. Once a person is interested in something, he will have an urgent desire and a strong demand to understand and master it. Teachers' tasks and methods drive students to write, but if they simply write without a certain sense of accomplishment, students' interest will disappear. Therefore, mathematics teaching should not only stay in textbooks, but also stimulate students' enthusiasm to write about math diary in various ways, and combine the "small classroom" in school with the "big classroom" in society. In teaching, I stimulate students' interest in learning from the following aspects:
(A) the use of modern information technology to stimulate students' interest in writing about math diary
Making full use of modern information technology and subject integration can not only overcome the difficulties in teaching, stimulate students' strong interest, expand their knowledge horizons, but also deepen their understanding of knowledge. Only when students understand it can they use it better. Students can only write math diary well if they are interested.
For example, when using calculator to explore the law, the introduction part presents the knowledge of palindromes to students with courseware. Students are deeply attracted by interesting palindromes, so they learn palindromes with strong interest. Next, use the animation effect of courseware to guide students to explore the laws in calculation, and finally use courseware to let students know more about palindromes. The whole class is full of interest. Through the application of modern information technology, they have deepened their understanding of knowledge and realized the endless fun contained in mathematics. Guided by this interest, the students wrote a better math diary with great interest.
At the same time, I also make the students' math diary into an electronic newspaper, and organize pictures, words, sounds and other information according to their interrelationships. Students can see their math diary through this form, feel the joy of success, further stimulate their desire to write, and further promote the formation of students' good habits.
(B) with real life, to stimulate students' interest in writing about math diary.
The new curriculum points out that "the relationship between mathematics and life is close". Therefore, the teaching space of mathematics should not be confined to the classroom, and the connection between mathematics and life should be strengthened in many ways. Guide students to pay attention to observation, use local materials in connection with real life, and choose topics close to students themselves, so that students will be interested and apply what they have learned.
For example, when learning the math knowledge in buying gifts, let students go to the supermarket to observe or accompany their mothers to buy things and observe how to buy gifts. How much did you spend to get a few things in these activities? How much did you actually spend and how much was it cheaper? How did you work it out? Students have a strong interest in such a problem that is closely related to real life, think actively, and finally learn a lot of knowledge in the activities of promoting consumption. After observing and thinking, ask the students to write it down in the form of "math diary". In this way, they are motivated to learn mathematics, and they really use mathematical knowledge and mathematical thinking methods to solve practical problems in real life.
(3) Stimulate students' interest in writing math diary through the exchange of mathematics activities and math diary.
In addition to using various teaching methods to stimulate students' desire for learning, we should also combine mathematics activities to improve students' interest in writing math diary. Let students participate in practice, discover mysteries and sum up laws.
For example, when learning the histogram, divide the students into five groups, count the skipping situation of the students in this group, and draw the statistical results into a histogram. Students are interested in statistics and communicate with each other in the same group, which not only enables students to firmly master the knowledge of statistical charts, but also exercises their brain and hands-on ability and the spirit of unity and cooperation among students. At the same time, students are also willing to participate in activities, thus enhancing students' interest in writing about math diary and writing about math diary with interest.
The level of students' writing about math diary is also uneven. Let students talk about the advantages and disadvantages of their diaries and what needs to be improved by using activities such as math diary exchange. Activities exude students' intelligence and make the classroom a stage to show their talents. At the same time, let students appreciate some good math diary, let students learn through communication and improve through learning.
