摘要
随着《普通高中数学课程标准(2017年版2020年修订)》的深入实施,核心素养已成为高中数学教育的核心目标。为克服传统“课时主义”导致的知识碎片化弊端,探索素养落地的有效路径,本文立足于“大概念”的统摄作用,对高中数学单元整体教学策略进行系统探讨。首先厘清了核心素养、大概念与单元整体教学三者之间的协同关系,进而提出“课标解读—教材梳理—学情分析”三位一体的大概念挖掘路径,最终构建了“贯通式情境、呼应式问题、项目式活动、嵌入式评价”的单元整体教学策略体系,并结合典型案例进行阐述,力求为素养导向的大概念单元教学提供一些有益的参考。
With the in-depth implementation of the Mathematics Curriculum Standards for Senior High Schools(2017 Edition,Revised 2020),core competencies have become the central goal of high school mathematics education.To overcome the knowledge fragmentation caused by traditional"period-based teaching"and explore effective pathways for realizing core competencies,this paper systematically investigates strategies for integrated unit teaching in high school mathematics based on the overarching role of"big ideas".It first clarifies the synergistic relationship among core competencies,big ideas,and integrated unit teaching.Subsequently,it proposes a tripartite path for identifying big ideas:"curriculum standard interpretation–textbook analysis–learner analysis".Finally,it constructs a strategic system for integrated unit teaching comprising"connected scenarios,echoic questioning,project-based activities,and embedded assessment",which is elaborated with typical teaching cases.This study aims to provide valuable references for big idea-based unit teaching oriented towards core competency development.
