职教云结合虚拟仿真在船体结构教学中的应用

The Application of Vocational Education Cloud Combined with Virtual Simulation in the Teaching of Hull Structure

船体结构传统教学过程中存在场景进不去、结构看不见、模型不真实等突出问题,影响教学效果。虚拟仿真技术改善了传统教学的不足,但同时虚拟仿真系统教学会给学生带来眼睛疲劳、眩晕、恶心等不适症状,影响学习效果。因此提出基于职教云平台开展线上线下混合式的船体结构虚拟仿真教学模式,精准把控课程教学的重难点,借助3D投影大屏、桌面版、VR眼镜等媒介,实施以行动导向教学法为指导的线下课堂教学,有效提升虚拟仿真教学成效。

There are prominent problems in the traditional teaching of hull structure,such as the inability to enter the scene,the inability to see the structure,and the unrealistic models,which affect the teaching effectiveness.Virtual simulation technology has improved the shortcomings of traditional teaching,but at the same time,virtual simulation system teaching can bring discomfort symptoms to students,such as eye fatigue,dizziness,and nausea,affecting learning effectiveness.Therefore,a hybrid online and offline virtual simulation teaching mode for hull structure based on vocational education cloud platform has been proposed,which accurately controls the key and difficult points of course teaching.With the help of 3D projection screens,desktop versions,VR glasses and other media,offline classroom teaching guided by action oriented teaching methods is implemented,effectively improving the effectiveness of virtual simulation teaching.
