要提高数学教学质量。对教师来说,中心问题是要上好课。要想把课上好,需要的条件很多。数学教学既是一门科学,又是一门艺术,它要求教师除了具有足够的知识水平和相当的教学能力外,还应该具有良好的教师素质和丰富的教学经验。这些要求是宏观的,似乎很抽象。但正是它们决定着教师的教学水平属于哪一个层次。并在教学活动的每一个角落都会有它们的反映。因此教师要想从根本上提高自己的教学水平,就应该从这些方面加强修养。如果从微观的,较为具体的角度来讨论怎样上好课,那么起决定作用的是备课了。钻研教材是备课过程中较为重要的一环。本文结合《有理数大小的比较》这节教材①,谈谈怎样钻研教材。一般说来,开始备课,总是先把要上的教材从头
To improve the quality of mathematics teaching. For teachers, the central issue is to take good lessons. If you want to get a good lesson, you need a lot of conditions. Mathematics teaching is not only a science but also an art. It requires that teachers not only have sufficient knowledge level and considerable teaching ability, but also have good teacher quality and rich teaching experience. These requirements are macro and seem very abstract. But it is they that determine which level a teacher’s teaching level belongs to. And they will be reflected in every corner of the teaching activities. Therefore, if teachers want to fundamentally improve their teaching level, they should strengthen their cultivation from these aspects. If we discuss how to get good lessons from a microscopic, more specific point of view, then the decision-making role is to prepare lessons. Studying teaching materials is an important part of the lesson preparation process. This article combines “Rational size of the comparison” in this section of the teaching material 1, talk about how to study materials. Generally speaking, when preparing lessons, you always start with the textbook you want to use.
