本文从“抓住易错问题、理解数学本质”的视角出发,提出数学教学中学生产生错误的原因,分别从双基基础教学、思想方法教学、能力素养培养等几个方面来阐述技巧,并结合案例进行说明,以期通过学生易错点的“以点及面”教学,成就数学教学的高效率. From the perspective of “grasping the error-prone problem and understanding the nature of mathematics”, this paper puts forward the reasons why students make mistakes in mathematics teaching, and elaborates the skills from such aspects as basic teaching of double bases, teaching of ideological methods and ability literacy cultivation, And combined with the case to illustrate, with a view to students through the wrong point “to point and surface ” teaching, achievement mathematics teaching high efficiency.
