"math diary" is to let students record their understanding, evaluation and views on the contents of daily mathematics teaching in the form of diaries, including their true mentality and thoughts in mathematics learning. What does the math teacher teach students to write, math diary? This is the first problem to be solved. As a math teacher, you can instruct students to write the following: 1. Math diary content 1, the experience of writing a class diary, what thoughts, experiences, inspirations, discoveries, etc. Students have it when they are studying math, having math classes or doing math homework. You can write it in a diary to record students' mastery, listening, cooperation, thinking, innovation and application of knowledge and skills in class. For example, we learned about "triangle" today, and learned what a triangle is, its characteristics, its classification and its wide application in practice. What I learned most in this lesson is the characteristics of triangles, and there is another thing I don't understand: why can an obtuse triangle have only one obtuse angle instead of all three angles? I asked several other students, and they didn't want to. I have to ask the teacher to tell me again tomorrow. Look, it's good to have a problem. It can make me think more and understand what I have learned thoroughly. 2. The thinking diary should record the thinking process of students in class, homework and problem solving. For example, the teacher told us a question: 58 million kilometers = () 1 100 million kilometers. One team did this: the forward speed between 10,000 km and 100 million km is 10000, so divide 58 million km by 10000 and move the decimal point four places to the left, which is 58 million km. I have another idea: first rewrite 1 10,000 kilometers into kilometers, which is 58 million kilometers, and then put the decimal point in the lower right corner of its billion digits, which is 58 million kilometers. How's it going? Is my method good? 3. The cooperative diary mainly records students' mutual help, mutual promotion, mutual learning and cooperation and communication with classmates in mathematics learning. I didn't listen carefully today, so I handed in my homework very slowly. If not, I'll ask my classmate in the same place, but he won't talk. I know this because I have been asking him questions and bothering him these days. I don't blame him. Alas! You must listen carefully in the future. So I asked Liu Xiaoping, and she told me very carefully. When I handed in my homework, the teacher praised me for doing well, and I was very happy. In fact, the teacher should praise that classmate. As for which classmate, I think everyone already knows. 4. Life diaries are mainly used to record interesting and personally experienced situations about mathematics that children encounter in their lives, so that students feel that there is mathematics everywhere in their lives. For example, at noon today, my mother asked me to buy 1 50 cents of white sugar and 2 Jin of soy sauce, and gave me a piece of 10 yuan. After I bought it, the salesman gave me 30 cents change from 6 yuan. On the way home, I calculated: 1 kg soy sauce 1 yuan.60, 2 kg is 3 yuan.20, plus 1 yuan.50 sugar, one * * spent 4 yuan.70, 10 yuan -4 yuan.70: 5 yuan Triangle, so he should call me 5 yuan Triangle more. I went back to the clerk, who took back the extra change and said, "You are so honest and a good student!" " "ah! I used mathematics, and the role of mathematics is so great! 5. Emotional diary mainly records the development and changes of students' emotions and attitudes in mathematics learning. For example, at noon today, I found Zhang Can copying Jin Tairan's math study guide. I thought for a while, should I report to the teacher? If it is reported, it is for her good; If you don't report it, you will hurt her. So I told the teacher and the teacher called her out. She didn't say a word when she came in, as if she were angry with me. What should we do about such a thing? 6. The exam diary mainly records the students' exam situation before the math exam, the problems in the exam and the experience summary after the exam. For example, today, after we finished the exam, our grades came down. I estimated that we could get more than 90 points, but I only got 87 points. I was careless and made a mistake. For example, "add two zeros at the end of an integer, and the original number will be expanded by 100 times." "This judgment question is wrong, because adding two zeros after 0 doesn't count. I overlooked this point. We must carefully analyze and consider the problem comprehensively in the future. 7. Explore the diary. It mainly records the process of students' independent inquiry, active discovery and practical innovation in mathematics. For example, when playing with a calculator, I found a phenomenon: 21-kloc-0/2 = 9, 43-34 = 9, 65-56 = 9, 76-67 = 9, 87-78 = 9 ... 32l-123 = 66. 654—456= 198,765—567= 198…… 432 1— 1234=3087,5432—2345=3087,6543—3456=3087, 7654-4567 = 3087 ... 54321-kloc-0/2345 = 41976,65432-23456 = 41976,76543-34567. Through research, I know that as long as you are willing to explore, you will make many wonderful discoveries, and then you will find how interesting mathematics is. 8. The story diary mainly records some math stories that students have happened or heard. For example, at home today, I asked my father a question: What is 10+ 10? Dad said, "20", and I said, "Wrong!" Dad said, "How much is it?" I said, "You should use 18, 10, 10 as the base. Isn't that 18? " After that, we all laughed. 9. The teacher's diary mainly records students' attitudes, feelings and suggestions to the teacher. Write a difficult problem. When students encounter unsolvable problems in learning and doing math problems, they can write these problems in their diaries and ask their teachers for help. In math class, I always don't understand the examples explained by the teacher, and I am puzzled and afraid to ask questions. I can also write them in my diary and ask the teacher for individual counseling after class. Students can write their own opinions and suggestions on math teacher's class, homework assignment, homework correction, extracurricular counseling, exam evaluation and so on. In the diary; If you have other opinions about the math teacher, or have something to say to the teacher, you can also write it in your diary. A student wrote in his diary: "Teacher: I don't know why today, I can't hear your math examples, so I can't do a few math homework today." In order to complete the study task assigned by you, I had to copy some students' answers. I'm terribly sorry. If you have time, can you give me more tutoring? "For another example, the schedule teacher praised me three times. On one occasion, Sun Pei could not move the decimal point. I stood up and said to him, "expansion moves to the right and contraction moves to the left." "This is easy to remember." The teacher praised me for my good summary. The second time is to do a problem that is both enlarged and reduced. I have my good method: synthesize first, determine whether to enlarge or reduce in the end, and then move the decimal point. The teacher praised my novel and unique method. The third time is that I have been actively answering questions. The teacher praised me for my energetic study. I really like this course. Teacher, I want to say to you: "You should praise us more in the future, and everyone should praise us. In this way, I can guarantee that every class in our class is happy. " 10, growth diary mainly records students' academic progress, existing problems and the process of correction. For example, in class today, my energy is always distracted. I always think about this and that, and my grades are also declining. It seems that I have fallen into a trap (lack of energy) and can't climb up. I think I must try my best to climb this damn trap! I also hope that students who fall into this trap will climb up as soon as possible. 1 1, the flash diary mainly records my experience, knowledge, experience and every success and Excellence in mathematics learning. After accumulation, I have written more than 30 articles about math diary. My classmates in our group praised me for my good writing. I summed it up and got some experiences: writing about the process of mathematical events that happened today; Write your own ideas about learning mathematics; The purpose of writing mathematics ... as long as you grasp the previous content and write carefully, you can write a good diary. My class's monthly evaluation is: You have been rated as a small celebrity in math diary, congratulations! We believe that according to the way you keep a diary, the whole class can write one good diary after another. Math points learned every day, good questions and questions you don't understand, etc. I usually ask them to write some recently learned mathematics and observe it in daily life. For example, mom and dad work hard. Please record your parents' working hours in a 24-hour system, and then write an article about math diary. Second, math diary's request: 1, seeking truth from facts. Write as much as you want, just write clearly what you want to say to the teacher so that the teacher can understand. Don't moan and scribble 2, informal, like chatting. When writing about math diary, students seem to chat face to face with their teachers. They can write whatever they want, and anything related to mathematics can be written. Write at will, regardless of the writing format and requirements, very casual. 3, in a few words, don't bother. Can students write math diary? If the sentence is clearly written, don't use two sentences. If you can write it clearly in one paragraph, don't use two paragraphs. Don't decorate it with flowery words. Don't be wordy. Don't confuse the teacher. 4. Write with content, not every day. Students learn math, have math classes, do math homework, have experience, have questions and have suggestions, they will write ... if not, they will not write and will not adhere to unity. In other words, if they have the above contents today, they can write today, if they don't, they can write tomorrow, and if they want to. Give it to the teacher when you are finished. Thirdly, marking requires math teachers not only to seriously guide students to write math diary, but also to take every math diary written by students seriously and comment on them one by one. Mathematics teachers should answer the questions raised by students in their diaries, answer them face to face, or write comments at the back of students' diaries, so as to show teachers' affirmation or negation of students' experiences, opinions and suggestions written in their diaries. Pay attention to guidance and strengthen encouragement. After reading the students' math diary, the math teacher should praise and encourage those who have written well, give guidance to those who have not written well enough, and summarize and improve those who have written creatively. Only in this way can it be meaningful to guide students to write math diary; Students' math diary will get better and better.
