图形与几何教学模式实施策略与案例研究——以四川师范大学附属实验学校为例

Implementation Strategies and Case Studies of Graphic and Geometric Teaching Models—Taking the Experimental School Affiliated to Sichuan Normal University as an Example

摘要: 本研究以四川师范大学附属实验学校2024届157名学生为研究对象，系统探讨“图形与几何”领域的教学改革实践。通过构建“技术赋能–分层实施–情境驱动”的三维教学模式，整合希沃白板、AR技术、分层学习包等创新工具，实施动态教学策略。实践表明，该模式使七年级学生空间观念测评达标率提升至87%，几何直观能力增长34%，教师信息技术应用能力合格率从61%提升至89%。本研究为义务教育阶段数学教学改革提供可复制的实践方案，具有显著的区域推广价值。

Abstract: This study systematically explores the teaching reform practice in the field of “Graphics and Geometry” by taking 157 students from the 2024 grade at the Experimental School Affiliated to Sichuan Normal University as the research subjects. By constructing a three-dimensional teaching model of “technology empowerment—hierarchical implementation—context-driven learning”, integrating innovative tools such as Seewo whiteboards, AR technology, and hierarchical learning packages, and implementing dynamic teaching strategies, the practice shows that this model has increased the pass rate of spatial concept assessment for seventh-grade students to 87%, enhanced their geometric intuition ability by 34%, and raised the pass rate of teachers’ information technology application ability from 61% to 89%. This study provides a replicable practical solution for the reform of mathematics teaching in compulsory education, with significant regional promotion value.
