摘要
聚焦基于STEAM理念的初中数学拓展课的教学研究,以“锐角三角函数”为例,详细阐述其教学过程、效果评估及反思。通过金字塔高度测算这一实际问题,引导学生深入探究锐角三角函数的应用实践,促使学生将抽象的数学知识与丰富多彩的现实生活紧密相连,提升学生运用数学知识解决实际问题的实践操作技能与综合应用能力,助力培养学生的跨学科素养。
This study focuses on the teaching research of junior high school mathematics enrichment courses based on the STEAM concept,using the topic of“acute angle trigonometric functions”as an example.It elaborates on the teaching process,effect evaluation,and reflections.By guiding students to explore the practical application of acute angle trigonometric functions through the real-world problem of calculating the height of a pyramid,the study helps students closely connect abstract mathematical knowledge with diverse aspects of real life.It aims to enhance students'practical skills and comprehensive application abilities in solving real-world problems using mathematics,and to foster their interdisciplinary literacy.This research also provides a reference for the improvement of junior high school mathematics teaching.
