所谓数学能力,就是学生利用数学知识、方法来认识和解决问题的一种能力。数学中的基本概念、基本定理、运算法则和公式、基本作图等是知识体系的核心,只有把这些核心知识教深教透,学生才能以此为框架,构建起立体式、有层次的认知结构,才能有效地减轻学生的学习负担,提高学生的数学能力。《面向21世纪上海市中小学数学学科教学行动纲领》指出:“必须正确处理学习主体与客体间的关系。要注重学生学习自行获取数学知识的方法,学会主动参与数学实践的本领,获取终生受用的数学基础能力和创造才能。”如何在数学教
The so-called mathematical ability, is the ability of students to use mathematical knowledge, methods to recognize and solve problems. The basic concepts, basic theorems, algorithms and formulas in mathematics, basic drawing and so on are the core of the knowledge system. Only by teaching these core knowledge deeply, students can use this as a framework to build a three-dimensional, hierarchical recognition Knowledge structure, can effectively reduce the student’s learning burden, improve students’ mathematical ability. The “Action Plan for Teaching Mathematics in Primary and Secondary Schools in Shanghai in the 21st Century” states: “The relationship between the subject of study and the subject must be properly handled. Students should pay attention to the methods of acquiring their own mathematical knowledge and learn the skills of taking the initiative to participate in mathematical practice, The basic mathematical skills and creative talents to use. ”How to teach in math
