数学概念的认知理解是高中生进行数学学习中的核心部分。数学概念反映了一类对象在空间形式和数量关系方面的本质属性,是学生进行数学学习的基础。高中阶段的数学有很多概念知识,涉及范围很广,几何、代数、三角等分支学科中都包含大量数学概念,成为学生学习的难点和重点。在传统的应试教育体系下,数学教学重解题、轻概念学习的现象十分普遍,导致很多学生缺乏对概念的真正理解,对以后的学习带来了一定的困难。因此,帮助学生理解和掌握数学概念就成为数学教学设计中的重点。一、充分利用概念的历史和现实背景一些数学老师认为给学生介绍概念的发展是浪费时
Cognitive understanding of mathematical concepts is a core part of high school mathematics learning. The concept of mathematics reflects the essential attributes of a class of objects in the relationship between spatial form and quantity, and is the basis of students’ mathematics learning. High school mathematics has a lot of concept knowledge, covering a wide range of geometry, algebra, trigonometry and other disciplines include a large number of mathematical concepts, as the difficulties and focus of student learning. Under the traditional examination-oriented education system, mathematics teaching re-solving problems and learning light concepts are very common, causing many students to lack a true understanding of the concepts and bring some difficulties to their future study. Therefore, to help students understand and master mathematical concepts has become the focus of mathematical teaching design. First, make full use of the historical and realistic background of the concept Some math teachers think it is a waste of time to introduce the concept to the students
