摘要
针对小学数学“角的度量”学习中机械模仿倾向显著、度量本质认知不足、动手操作活动缺失等问题,重构教学活动设计.沿循“抽象—类比—创造—反思”的学习路径,以现实情境问题的解决为起点,唤醒学生已有度量活动经验,沟通角的度量与长度、面积测量的内在逻辑关联,引导学生经历量角工具的创造过程.以此突破传统教学中量角画角机械训练的局限,促进学生理解测量单元数学实质,增强数学类比的意识和能力,实现数学学习从模仿走向创造.
Addressing issues such as significant mechanical imitation tendencies,insufficient cognitive understanding of measurement principles,and the lack of hands-on operational activities in the learning process of“Angle Measurement”in primarg school mathematics,this study reconstructs teaching activity design:Following the learning path of“abstraction-analogy-creation-reflection,”it begins with solving real-world contextual problems to awaken students’existing measurement activity experiences,establishes the intrinsic logical connections between angle measurement and the measarements of length and area,and guides students through the creation process of angle-measuring tools.This approach overcomes the limitations of traditional mechanical training in angle measurement and drawing,fosters students’comprehension of the mathematical essence of measurement units,enhances their awareness and ability in mathematical analogy,and transitions mathematical learning from imitation to creation.
