分析当前程序设计类专业课的实验教学问题，提出基于EduCoder在线实训平台，构建以“基础实验—综合实验 —课程设计—程序设计竞赛”为内容，从“点—线”到“面”再到“体”的循序渐进、螺旋上升的实验教学模式。对两年来两门课 程的实验教学数据整理和分析，数据表明基于EduCoder平台“点—线—面—体”的实验教学模式有利于培养优秀的计算机专 业学生。

After analyzing the current problems of experimental teaching in program design courses, this paper proposes a progressive and spiral experimental teaching mode based on the EduCoder online training platform, with the content of "basic experimentscomprehensive experiments-course design-program design competition", from "Point-Line" to "Surface" and then to "Body". The experimental teaching data of the two courses in the past two years are organized and analyzed, the data shows that the "Point-LineSurface-Body" experimental teaching mode based on the EduCoder platform is beneficial for cultivating excellent computer major students.
