数学概念教学是整个数学教学的重要环节,也是数学教学改革的攻关课题之一。数学概念教学的根本任务是通过教学,正确有效的揭示概念的内涵与外延,即让学生全面地领会牢固地掌握概念所包括的一切对象的共同本质属性以及适合于该概念的一切对象的范围。让学生练习给数学概念下定义,不仅能加深对概念的理解,还能培养和发展学生的比较、分析、综合、抽象和概括等一系列的思维能力。下面将从三个方面谈谈如何进行概念教学。一、根据学生认识水平的变化,深化进行概念教学在教学的过程中应根据学生年龄、知识的增长,认
Teaching of mathematical concepts is an important part of the whole mathematics teaching, and it is also one of the key topics in mathematics teaching reform. The basic task of mathematical concept teaching is to correctly and effectively reveal the connotation and extension of concepts through teaching so that students can comprehensively grasp the common essential attributes of all the objects covered by the concepts and the scope of all the objects suitable for the concept. Let students practice the definition of mathematical concepts, not only to deepen the understanding of concepts, but also to develop and develop students' comparison, analysis, synthesis, abstraction and generalization and a series of thinking ability. Here are three aspects to talk about how to carry out the concept of teaching. First, according to the level of awareness of students to deepen the concept of teaching in the teaching process should be based on the age of students, knowledge growth, recognition
