义务教育数学课程标准修订的新视角:指向小学图形与几何领域的素养及其达成

A New Perspective on the Revision of Compulsory Education Curriculum Standards:Mathematics:the Core Competencies in the Areas of Graphics and Geometry in Primary School and Their Attainment

《义务教育数学课程标准(2022年版)》确立了以核心素养为导向的课程目标。在小学阶段图形与几何领域中,核心素养主要表现为空间观念、量感、几何直观和推理意识。课标中的四个重要变化是促进素养达成的关键:完善主题结构,增强空间观念;单列关键词,增强体验,突出量感;新增尺规作图,增强几何直观;明确基本事实,加强推理意识。课标新增学业要求和学业质量标准,旨在为素养达成提供相应的评价依据。

Compulsory Education Curriculum Standards:Mathematics(2022 Edition)has established the core competencies-oriented curriculum objectives.The core competencies related to graphics and geometry in primary school are mainly spatial concept,sense of quantity,geometric intuition and reasoning awareness.Four important revisions in the standards are key to promoting the achievement of competencies:improving the structure of the subject to enhance students’concept of space;listing key words to enhance the experience and highlight students’sense of quantity;adding contents about drawing with compass and ruler to promote students’geometric intuition;and clarifying basic facts to strengthen students’sense of reasoning.The new academic requirements and academic achievement standards are designed to provide a corresponding assessment basis for the achievement of competencies.
