      ”Mathematics Curriculum Standards" pointed out: "Mathematics is a kind of human culture,Its content, ideas, methods, and language are an important part of modern civilization."therefore,In the process of teaching mathematics,How to perfectly combine teaching content, teaching ideas, teaching methods, teaching language and teaching methods,Should become an important research topic for mathematics teachers.Teachers should not only focus on the results of students' thinking,Should pay more attention to the learning process,Pay attention to the two-way communication between teachers and students.The author seized the opportunity of curriculum reform,For several years, I insisted on encouraging students to write math diary,And insist on reviewing.Practice has shown that writing a math diary can cultivate students' emotions towards mathematics,Can strengthen the communication between teachers and students,So as to improve teaching methods,Improve math grades.

      1. It is conducive to understanding students' learning and thinking conditions,Teach students in accordance with their aptitude

      A classmate in the class I just took wrote: In elementary school,My math grades have always been good,It was okay at the beginning of junior high school,But when learning graphics,Especially when it comes to proof questions,Feel a little difficult,I asked the teacher again and again,Until I figure it out.More times,The teacher became a little impatient,Until one time he said,"It's not so simple?Think about it before asking the teacher in the future!"I haven't asked the teacher again since then.I don't like learning math anymore,Mathematics scores are not as good as one time.How I hope my math scores can improve,You tell your classmates to keep a math diary,In this way, we can understand our learning thinking and learning situation,If you don't understand, you can ask for advice.thus,I learned about the student's learning emotions, academic performance and psychological barriers,At the same time, I also reflect on whether some of the teacher's actions are appropriate.I wrote in this classmate's diary: "Thank you very much for your trust in me,I was moved by your persistent spirit,You can ask me for advice anytime in the future,I will definitely help you!"

      In the course of the teacher's demonstration of problem-solving in the classroom,Some students think for themselves,But did not communicate with the teacher,The discussion of different solutions to the exercises in the homework,Learning emotions and experiences,It can be recorded in the form of a math diary.such,The math diary has become a fixed bridge for mutual understanding and communication between teachers and students.

      2. Conducive to cultivating students' ability to discover problems and analyze and solve problems

      After a student learned the nature of the vertical bisector of a line segment,Wrote like this: self-study tonight,When doing a proof question in the workbook,I heard what the teacher said to me a few days ago: "You have to prove this problem congruently twice (the title is: Known: AB=AC,DB=DC,AD and BC intersect at point E,Verify: EB=EC) There is nothing wrong,Originally I didn't want to deduct points,But in order to remind you to use the easiest way to solve the problem,I still deducted one point from you."After reading the title,Can't help but feel confused: Is there an easier way to this question?经过几分钟的思考,我终于想出了一种简单的方法来证明线段的垂直平分线的这一问题。我为此感到非常高兴,因为今天我克服了另一个刻板印象,成为学习中的成功人士。我在评论中写道:“老师的话,给你启示我真的很高兴实际上, 我们将继续在解决问题的过程中进行反思和总结,将提出许多独特的解决方案。老师希望您能找到更多更好的捷径来解决问题。“通过日记,我发现学生的分析和解决问题的能力有了显着提高。

      3。 有利于培养学生的分类能力, 总结和组织

      一位学生在研究了“有理数”一章后写道:“零,英文字母是零,它的特征表明没有,那是, 与任何数字相乘得到零; 它除以任何数字(除自身外)为零; 加减任何数字即可得到数字本身; 例如:a×0 = 0,0÷a = 0; a + 0 = a; a-0 = a。它没有对等。 相反的数字和绝对值本身是对的; 数字线上的原点由它表示; 它既不是正数也不是负数; 这都是自然数它也是一个整数; 它是正数和负数家族的中间人,不要干扰他们。 它的优点是无处不在,而且它的缺点是没有。 它的人生座右铭是,我天生就是有用的。“我写给他的评论是:“您可以很好地归纳零的相关性质:分为几类,有条理,说明您已经动用了大脑,这真的是“一项艰苦的工作, 一收”,我相信您的分类能力, 总结和组织将得到改善。"

      学生分类 总结和整理他们在必要时学到的知识,这是学生必须具备的数学素养之一。学生独立进行分类, 总结和整理他们所学的知识,可以帮助学生建立知识网络,积极解决问题的思维。

      第四, 有利于激发学生的学习兴趣,调动学生的学习热情。

      刚转学到我们学校的一个学生写道:这个学期我来了一所中文学校,从乡村到城市,生活条件好多了但是因为学习不好我担心同学会看不起我这样我就不敢举手在课堂上讲话。在今天的数学的第三季度,老师叫我回答问题,我必须低下头固执地回答这个问题,我刚说完全班同学都大笑起来此时,老师不仅及时阻止了他们,他还说:“虽然龙永兴在回答问题时口吃了一点,主要是因为太紧张但是答案是正确的,别笑不会太久他会说得比你们好因为他很努力学业成绩将超过同班同学中的相当一部分。”听到了,我无法表达内心的喜悦,我暗自下定决心,我必须支持老师所说的。 我对这位同学的评论是:“作为老师,像这样说很常见有这样的决心对你有好处,不断克服教室里的不良心态,老师给了你一句话, “有意愿的地方, 将会完成”,老师期待着您的好消息。“一个学期后,通过他自己的努力 这个成绩不好的学生取得了不错的成绩,学期末, 他被任命为学习活动家,他得知消息后,第一个打来电话告诉我,我放心了。
