近年来优化课堂教学是小学数学教学改革中深入研究的一个问题。课堂教学是个有机的整体,它是以教材为中介,师生双边活动的过程。优化课堂教学的关键在于正确处理教与学的关系,发挥师生双方的积极性,通过准确、科学的途径获取知识、形成能力。但是由于数学本身高度的抽象性和小
In recent years, optimizing classroom teaching is an issue that is deeply studied in the elementary mathematics teaching reform. Classroom teaching is an organic whole, which is based on teaching materials as an intermediary, the process of bilateral activities of teachers and students. The key to optimizing classroom teaching lies in correctly handling the relationship between teaching and learning, giving play to the enthusiasm of both teachers and students, obtaining knowledge and forming capabilities through accurate and scientific methods. But due to the high degree of abstraction and smallness of mathematics itself
