在学校教育中,数学是一门知识性、概念性、严谨性和应用性极强的基础课程。它具有高度的抽象性、严密的逻辑性和广泛的实用性。其概念严谨、准确、精练,是反映现实世界的空间形式和数量关系本质属性的思维形式。它揭示了事物的本质属性和相互间的内在联系,是数学知识体系中的基本元素,是数学基础知识的核心成分。积极开展初中数学概念教学,既是学习和掌握数学基础知识的前提,又是奠定数学课程活动的基石,更是培养学生进行正确抽象概括、形成方法和理论的先决条件。本文在重新审视概念教学意义上,主要从有效模式构建和良好途径畅通等角度,试对此做出抛砖引玉之论。
In school education, mathematics is a basic course of knowledge, concept, rigor and application. It has a high degree of abstraction, strict logic and a wide range of practicality. The concept of rigorous, accurate and concise, is to reflect the real world of the relationship between the spatial form and quantity of the nature of the relationship between the forms of thinking. It reveals that the essential attributes of things and the interrelationships between them are the basic elements in mathematical knowledge system and are the core components of the basic knowledge of mathematics. To actively carry out junior high school mathematics concept teaching is not only the premise for learning and mastering the basic knowledge of mathematics, but also the cornerstone for laying the foundation for mathematics curriculum activities. It is also a precondition for training students to correctly abstracted and form methods and theories. In the sense of reexamining the concept of teaching, this article tries to give some suggestions on how to construct a valid mode and how to get a good way.
