CRA教学在数学学习障碍教学中的应用

The Application of CRA Sequence in the Mathematics Teaching for Students'with Learning Disabilities

具体-表征-抽象(Concrete-Representational-Abstract,CRA)教学是一种基于证据的实践,通过3种渐进式的数学教学方式,使用直接教学结合三维操作工具及视觉化的支持,为数学学习障碍生提供一种有效的方法,帮助他们建立概念性知识与程序性知识之间的联结,提高教学效率和学习效果。对CRA教学的理论基础与相关研究进行梳理,阐述其在数学教学中的具体应用,旨在为我国数学学习障碍学生的教学研究与实践提供一定的参考。

(CRA)Sequence is an evidence-based practice that provides an effective approach for students with learning disabilities in mathematics through three progressive math teaching methods and by using direct teaching combined with 3D operational tools and visual support to help them establish the link between conceptual and procedural knowledge,so as to improve the teaching efficiency and learning effect.This paper analyzes the theoretical basis and related research of CRA Sequence,and expounds its specific application in mathematics teaching,aiming to provide references for the teaching research and practice for students with learning disabilities in mathematics in China.
