地图投影课程虚拟仿真实验教学研究

Research on virtual simulation experimental teaching of Map Projection course

以地图投影课程为例,从知识体系重构、创新实践的角度探索了虚拟仿真实验教学改革实践。梳理了地图投影课程实验教学内容体系和知识结构,构建了一个系统的理论与实践有机融合的虚拟仿真实验教学体系,探索了“线上+线下”混合式互动实验教学模式;在D3.js平台技术支撑下,开发了地图投影与变换虚拟仿真实验平台,动态演示、形象展示地图投影表象、变形规律,提高了学生解决地图投影与空间变换等复杂问题的实践能力,同时也为虚拟仿真实验教学项目的普及推广和深化改革提供了新思路。

Taking the Map Projection course as an example,this study explores the reform and practice of virtual simulation experimental teaching from the perspective of knowledge system reconstruction and innovative practice.A thorough review of the experimental teaching content and knowledge structure of the Map Projection course leads to the construction of a virtual simulation experimental teaching system that integrates theoretical knowledge with practical skills,exploring a blended"online+offline"interactive experimental teaching model.With the technical support of the D3.js platform,a virtual simulation experimental platform for map projection and transformation is developed.This platform dynamically demonstrates and vividly illustrates the representation and deformation patterns of map projections,enhancing students'practical abilities to solve complex problems related to map projection and spatial transformation.Additionally,it provides new insights for the popularization and further reform of virtual simulation experimental teaching projects.
