数学概念是人对客观事物中有关数量关系和空间形式方面本质属性的抽象。数学教学首先要搞好概念教学,这是由数学学科本身的特点所决定的:正确理解各种数学概念是掌握数学基本知识和基本技能的基石;是发展数学思维的必要前提条件。当前小学数学概念教学中存在不少问题:忽视概念的教学,在讲概念时一带而过;忽视概念的形成,在教学概念时往往强输硬灌,要求学生死记硬背。忽视概念间的联系;忽视概念的灵活运用。本文从充分利用感性经验,帮助学生形成概念;运用变式,突出概念的本质属性;运用迁移规律,促进举一反三;形成概念体系,达到融会贯通等方面对如何提高概念教学的有效性作了一些探索。
Mathematical concepts are abstractions of the essential attributes of the objective things in terms of quantity and space. First of all, to improve the concept of teaching mathematics teaching, which is determined by the characteristics of the mathematical discipline itself: a correct understanding of various mathematical concepts is to grasp the basic knowledge of mathematics and basic skills; is the necessary prerequisite for the development of mathematical thinking. At present, there are many problems in the teaching of mathematical concepts in primary schools. Teaching that ignores concepts is not only a part of the teaching of concepts, but also overlooks the formation of concepts. Ignoring the connection between concepts; ignoring the concept of flexible use. This article makes some exploration on how to improve the effectiveness of concept teaching from the aspects of making full use of perceptual experience, helping students to form concepts, using the variations, highlighting the essential attributes of concepts, using the law of migration, and promoting one-sidedness, forming a conceptual system, and reaching a consensus.
