数学直观想象核心素养在初中数学教学中的应用研究

Research on the Application of Mathematical Intuitive Imagination Core Literacy in Junior High School Mathematics Teaching

摘要: 《义务教育数学课程标准(2022年版)》对初中数学教学提出了更标准的要求，强调落实素质教育理念，改革学生学习方式，对课程改革提供了方向。初中数学教学不仅要实现素质教育背景下的全新教学目标，同时也要兼顾培养每一位学生的数学核心素养。数学直观想象作为数学学科核心素养之一，对学生数学能力的提升至关重要。故本文从实物直观、几何直观、模像直观以及言语直观的角度出发，通过列举部分案例探讨直观教学法在初中数学课程中的运用。随着GeoGebra等教学软件的发展，数学直观性教学的优势逐渐突显，不但有利于学生将形象思维发展至抽象思维，而且可为学生构建多元化思维空间从而提高思维能力。基于此，数学直观教学应获得足够重视与广泛应用。

Abstract: The Compulsory Education Mathematics Curriculum Standards (2022 Edition) puts forward more standard requirements for junior high school mathematics teaching, emphasizes the implementation of the concept of quality education, reforms students’ learning methods, and provides a direction for curriculum reform. The teaching of mathematics in junior high school should not only achieve the new teaching goal in the context of quality education, but also take into account the cultivation of the core literacy of mathematics of each student. As one of the core literacies of mathematics, intuitive imagination is very important for the improvement of students’ mathematical ability. Therefore, from the perspectives of physical intuition, geometric intuition, image intuition and verbal intuition, this paper discusses the application of intuitive teaching method in junior high school mathematics curriculum by citing some cases. With the development of teaching software such as GeoGebra, the advantages of intuitive teaching of mathematics have gradually become prominent, which is not only conducive to the development of students’ visual thinking to abstract thinking, but also can build a diversified thinking space for students to improve their thinking ability. Based on this, the intuitive teaching of mathematics should be paid enough attention and widely used.
