摘要
回顾了测绘工程专业核心课程《大地测量学基础》教学改革主要成果特点,指出了慕课(MOOC)知识点碎片化到私播课(SPOC)结构化思维转变的重要性,利用私播课背景下BOPPPS教学模式探究了本课程与GNSS课程横向融合的三维坐标教学内容单元整体教学设计。通过三维坐标表达形式、广义三维坐标微分和大地高大地纬度快速迭代解法等优化分析以及GNSS电离层延迟建模、网平差模型和三维坐标改化等拓展应用探讨,旨在构建测绘专业私播课单元整体教学设计案例并提升学生结构化思维能力。
It is investigated the main characteristics of the teaching reform achievements of the"Foundation of Geodesy",which is the core course of surveying and mapping engineering,and it is very important to transform the knowledge fragmentation of MOOC into structured thinking of small private online course(SPOC).Then,the teaching model of BOPPPS is employed to unit overall teaching design of the three-dimensional coordinate content under integration of this course and the GNSS course.Through the optimization analysis of 3D coordinate expression,generalized 3D coordinate differential and rapid iterative solution of geodetic coordinate,as well as GNSS ionospheric delay modeling,network adjustment model and 3D coordinate modification,etc.,it focues on building a case of unit overall teaching design for SPOC,and improving students’ structured thinking ability of surveying and mapping major.
