“数学是思维的体操。”让学生掌握基本的数学思想和方法,培养和发展学生的思维能力是数学教学的—个重要任务,也是规范教学,减轻学生学业负担,提高教学质量的有效途径。问题是数学的心脏,方法是数学的行为,思想是数学的灵魂。不管是数学概念的建立,数学规律的发现,还是数学问题的解决,乃至整个“数学大厦”的构建,都离不开数学思想方法的培养 “Mathematics is the gymnastics of thinking. ” To enable students to master the basic mathematical thinking and methods, training and development of students ’thinking ability is an important task in mathematics teaching, but also standardize teaching, reduce students’ academic burden and improve teaching quality effectively way. The problem is the heart of mathematics, the method is mathematical behavior, the idea is the soul of mathematics. Whether it is the establishment of mathematical concepts, the discovery of mathematical laws, or the solution of mathematical problems, and even the building of “mathematical mansion,” we can not do without the training of mathematics and ideology
