在小学数学教学中,概念是基础性知识,是学生学好数学、构建知识系统的有效保证与基石。但在实际教学过程中,有些学生难以透彻理解数学概念,或者对概念性知识缺乏强烈的学习欲望,因而学习效率不高。这包括了教师与学生两方面的原因。首先,从小学生角度看,以形象思维为主,抽象思维能力较低,不能全面而准确地理解概念,难以运用数学语言加以表达。其次,从教师方面看,不少教师过于依赖教材与教参,单纯讲解,不利于学生理解概念。另外,由数学概念自身看,有着较强的概括性与抽象性,与生
In elementary mathematics teaching, the concept is basic knowledge, which is an effective guarantee and cornerstone for students to learn math and construct knowledge system. However, in the actual teaching process, some students find it difficult to thoroughly understand the concept of mathematics, or lack of a strong desire for learning about conceptual knowledge, so learning efficiency is not high. This includes both teacher and student reasons. First of all, from the point of view of pupils, taking the image thinking as the main factor, the abstract thinking ability is low, the concept can not be comprehensively and accurately understood, and it is hard to use mathematical language to express it. Second, from the teacher’s perspective, many teachers rely too much on teaching materials and teaching parameters, simply to explain, is not conducive to students to understand the concept. In addition, by the mathematical concept itself, has a strong generality and abstraction, and students
