概念是人们在反复的实践和认识过程中,将事物共同的本质特点抽象出来,加以概括形成的对事物的认识,具有抽象性、概括性及语言的严密性等特点。纵观现在的小学数学课堂,概念教学普遍存在以下现状:一是脱离学生的数学现实,导致学生对概念的理解苍白无力;二是学生缺少自主探究的机会和时空,无法理解概念的本质内涵;三是忽视概念的综合应用,抑制学生解题能力的发展。笔者认为,教师 Concept is that people in the process of repeated practice and understanding, the common essence of things abstract out, to be formed on the understanding of things, with abstract, general and language rigor and so on. Throughout the present primary mathematics classroom, the concept teaching universally exists in the following status quo: First, from the mathematics reality of students, resulting in students’ weak understanding of concepts; Second, students lack the opportunity and space-time of independent inquiry, can not understand the essence of the concept; Third, ignore the comprehensive application of concepts and restrain the development of students’ ability to solve problems.
