高中数学拓展性课程教学策略及开发路径研究
Research on Teaching Strategies and Development Paths of High School Mathematics Expansionary Curriculum

拓展性课程作为基础性课程的延伸与发散，具有其独特的作用和意义，多元性、发展性、创造性、生活性都是其最重要的特征。对于高中数学拓展性课程的开发应该坚持以学习者为中心的思想，秉承搭建趣味情境激发学生兴趣、设置问题链贯穿教学过程、增加交互设计引导师生沟通、明确内容主题驱动任务完成等策略，在学习者、教授内容、授课者之间做好平衡。在此基础上，提出了四条开发路径：图形结合，丰富数学教育内容；实践操作，落实数学探究活动；技术辅助，提升数学教学效率；文化陶冶，贯彻数学核心素养。
As the extension and divergence of the basic curriculum, the expansionary curriculum has its unique role and significance, and its most important characteristics are diversity, development, creativity and liveliness. For the development of high school mathematics expansionary curriculum, we should adhere to the learner-centered idea, adhere to the strategies of building interesting situations to stimulate students’ interests, setting up problem chains to run through the teaching process, adding interactive design to guide the communication between teachers and students, and clarifying the content theme to drive the task completion, so as to make a good balance between learners, teaching content, and communicators. On this basis, four development paths are proposed: graphic combination to enrich the content of mathematics education; practical operation to implement mathematical exploration activities; technical assistance to improve the efficiency of mathematics teaching; and cultural edification to implement the core literacy of mathematics.
