数与代数的内容是义务教育阶段教学课程的重要组成部分,它的重要性和基础性是显而易见的,是学生认识数量关系,探索数学规律以及建立数学模型的基石。它可以帮助学生从数学的思维角度,更准确、更清晰地认识、描述和把握现实世界。一、关注教学思维过程1.联系实际,体现知识的形成和应用过程运用所学知识进一步探究新的实际问题,提高对数学内容及其应用的理解,从而体现“实践——理论——实践”的认识过程。案例1:如:在进行“无理数的概念”教学时,设计如下的数学实
The content of numbers and algebra is an important part of the curriculum of compulsory education. Its importance and foundation are obvious. It is also the cornerstone of students’ understanding of quantitative relations, the exploration of mathematical laws and the establishment of mathematical models. It can help students understand, describe and grasp the real world more accurately and clearly from the perspective of mathematics. First, pay attention to the process of teaching thinking 1. Contact with practice, reflect the formation and application of knowledge process Use the knowledge to further explore new practical problems, improve the understanding of the mathematics content and its application, so as to reflect the “practice - theory - practice ”Understanding process. Case 1: Such as: In the “concept of irrational numbers ” teaching, the following mathematical design
