基于问题链教学法的高中数学独立性检验的教学设计研究
Research on Teaching Design of High School Mathematics Independence Testing Based on Problem Chain Teaching Method

随着计算机技术和人工智能融入社会，大数据时代已经到来，统计学作为方法论和工具有着不可忽视的重要作用，其中独立性检验作为高中数学中统计学案例之一是统计学教学内容中重要的一环，同时又与大学概率论课程密切相关，因此文章选取独立性检验内容，从独立性检验和问题链教学法的研究现状出发，阐述理论基础，对课程标准、学情、教学目标、教学结构等进行分析，依托问题链教学法设计教学环节，提供教学评价机制，从教师“教”和学生“学”两方面考虑实际存在的问题并进行讨论，旨在帮助学生更深入地把握独立性检验的本质和蕴含的统计思想，为教师展开数学课堂教学进行问题链设计提供借鉴，同时顺应新课改背景，为培养创新型人才提供教学新角度。
With the integration of computer technology and artificial intelligence into society, the era of Big Data has arrived. Statistics plays an important role as a methodology and tool that cannot be ig-nored. The independence test, as one of the statistical cases in high school mathematics, is an im-portant part of the statistical teaching content; at the same time, it is closely related to the college Probability theory course. Therefore, this article selects the content of independence testing, starts from the current research status of independence testing and problem chain teaching methods, elaborates on the theoretical basis, analyzes the curriculum standards, learning situation, teaching objectives and teaching structure. This article designs teaching links based on the problem chain teaching method, provides teaching evaluation mechanism, considers and discusses actual problems from both the teachers’ “teaching” and students’ “learning” aspects, aims to help students gain a deeper understanding of the essence and statistical ideas behind independence testing, providing a reference for teachers to design problem chains in mathematics classroom teaching, while also adapting to the background of the new curriculum reform and providing a new teaching perspective for cultivating innovation talents.
