新一轮教学改革的背景下“一例到底”式教学引起教育界的关注与重视。“一例到底”式教学广泛地应用于高中思想政治课，在一线教学实践中出现了案例资源开发难度大、案例编制不够严谨科学、问题设计不够合理恰当、对师生能力要求过高等问题。本文以高中政治《经济生活》第八课第一框《国家财政》教学为例，结合近几年全国及广东省优质课大赛中相关教学课例提出“一例到底”式教学的具体操作程序，对“一例到底”式教学进行教学设计研究。第一，“一例到底”式教学在高中政治课中的应用有着广泛的基础和深厚的土壤，实践证明“一例到底”式教学应用于高中政治课教学中具有一定的优势。从课堂测验成绩分析，思想政治课“一例到底”式教学更具逻辑性，在帮助学生理解、记忆知识点上具有一定的积极作用。从实证调查结果分析，思想政治课“一例到底”式教学有利于提高教学效率，有利于培育学科核心素养，有利于促进师生共同成长。第二，针对“一例到底”式教学在高中政治课应用中存在的问题，本文认为，可以利用建立“一例到底”式教学资源共享平台、发挥集体力量，优化集体备课制度、加强教师培训，提升教师水平、激发学生兴趣，强化学生主体地位等策略对思想政治课“一例到底”式教学进行优化提升。一方面应对目前“一例到底”式教学存在的问题，另一方面使“一例到底”式课堂教学效果更加理想。
