STEM教育理念下的初中数学“扇形统计图”的探究式教学设计——以“绘制浙江地形统计图”项目为例

Inquiry Teaching Design of “Fan Chart” in Junior Middle School Mathematics under STEM Education Concept—Taking the Project of “Drawing the Topography Statistical Map of Zhejiang” as an Example

摘要: STEM是科学、技术、工程、数学四门学科英文首字母的缩写，具有跨学科与探究性学习的特征。本文基于STEM教育理念，在初中数学教学中融合了地理科学，信息技术，桥梁工程。以Excel软件为工具，通过创设调查浙江地形统计图的问题情景，对初中数学“扇形统计图”进行了项目化探究式的教学设计——绘制出浙江地形统计图，以提升学生的学习兴趣，并获得相应的数学活动经验。

Abstract: STEM is the abbreviation of the English initials of science, technology, engineering and mathemat-ics, which is characterized by interdisciplinary and inquiry-based learning. Based on STEM educa-tion concept, this paper integrates geographic science, information technology and bridge engineering in junior middle school mathematics teaching. Using Excel software as a tool, by creating a problem scenario to investigate the topography of Zhejiang, this paper carried out a project-based inquiry teaching design on the “fan statistical map” of junior middle school mathematics, drawing the topography of Zhejiang, in order to enhance students’ learning interest and obtain the corre-sponding mathematical activity experience.
