指向数据意识培养的小学数学课堂教学——以苏教版“统计与概率”领域下的百分数教学为例

Primary School Mathematics Classroom Teaching Aimed at Cultivating Data Awareness-Taking Percentage Teaching in the Field of Statistics and Probability Published by the SU Edition as an Example

《义务教育数学课程标准(2022版)》明确指出,数据意识是小学阶段数学核心素养之一,也是“统计与概率”领域所对应的主要学科核心素养。文章结合苏教版六年级上册“百分数的意义”,从数据意识的角度,分析百分数这一内容跨领域调整的意图,并从关注知识本质内涵、准确定位教学目标和科学建构教学活动三个方面,探究在小学数学课堂中培养学生数据意识的有效策略。

The Mathematics Curriculum Standards(2022 Edition)clearly states that data awareness is not only one of the core competencies of mathematics for primary school students,but also the corresponding core competency in the realm of the“Statistics and Probability”.This paper takes the lesson“What Percentages Mean”,from the sixth-grade textbook published by Jiangsu Education Press,as an example to analyze the intentions behind the cross-disciplinary adjustment of this content from the perspective of data awareness.It also investigates effective strategies for cultivating students’data awareness in primary school mathematics classes from three aspects:focusing on the intrinsic essentials of knowledge,accurately formulating teaching objectives as well as scientifically performing teaching activities.
