主题活动中培养学生量感实践——以物体容积为例

Cultivating Students’ Sense of Quantity in Thematic Activities—A Case Study of Object Volume

摘要: 《义务教育数学课程标准（2022年版）》明确指出要发展学生量感，强调通过实践探究助力学生建立对“量”的直觉与估测能力。主题活动契合新课标“做中学”理念，为落实核心素养目标提供了切实可行的路径。量感是数学核心素养的关键构成，是学生理解数量关系、解决实际问题的核心能力。本课题旨在研究主题活动中培养学生量感的实践路径与发展规律。

Abstract: The Mathematics Curriculum Standards for Compulsory Education (2022 Edition) clearly states that students’ sense of quantity should be developed, emphasizing that practical exploration helps students build intuition and estimation ability for “quantity”. Thematic activities align with the “learning by doing” philosophy of the new curriculum standards, offering a feasible pathway for realizing the goals of core competencies. The sense of quantity is a key component of mathematical core competencies and a fundamental ability for students to understand quantitative relationships and solve real‑world problems. The purpose of this research is to study the development of students’ sense of quantity through thematic activities.
