10月20日，我校小学部数学教研组三位骨干教师继续赴紫荆小学，参与主题为《“支架赋能，思维可见——从“会算平均数”到“懂统计意义”》的两校联合教研活动。老师们共同观摩韩小羽老师执教的《平均数的意义与计算①》一课。本课依托STAR备课模型设计，打破重计算、轻说理的传统模式，聚焦概念意义建构，搭建情境、工具、图形与语言多层学习支架，打通新旧知识、图形与数量的关联，引导学生思辨说理，发展数据意识。课后，两校教师围绕本节课支架的设计与运用、统计素养在课堂中的落实等要点深入交流，分享教学思考，碰撞教学思路，在研讨中互学共进。

On October 20, three teachers from our primary math group visited Zijing Primary School for a joint research activity. They observed Ms. Han Xiaoyu’s lesson, “The Meaning and Calculation of the Mean.” Using the STAR model, the lesson built multi-layered scaffolds to help students understand statistical meaning and develop data awareness. Afterwards, teachers from both schools exchanged views on scaffold design and statistical literacy, sharing ideas and learning from each other.
