概念是小学生学习数学知识的基础,对于培养学生理解能力以及发展数学思维起到决定性作用。本文从把握教学目标,处理认知矛盾;创设现实情境,引入新概念;利用迁移规律,构建概念体系;运用生活实践,发展数学思维四个方面进行阐述,旨在培养学生的理解能力。 The concept is the basis for primary school students to learn mathematical knowledge, which plays a decisive role in cultivating students’ ability to understand and develop mathematical thinking. This article elaborates four aspects: grasping the teaching goal, dealing with the cognitive contradiction, creating the realistic situation, introducing the new concept, using the law of migration, constructing the concept system, applying the life practice and developing the mathematical thinking, so as to cultivate the students’ understanding ability.
