摘 要:虚拟仿真技术具有沉浸性、多感知性、自主性和交互性的显著特点,在很多领域得到了广泛的应用。在教育领域,虚拟仿真技术可以将二维知识和图片三维立体化,建造出自主感知的教学模式,改善刻板的教育方式,增强实践教育手段,极大地提升教学质量。文章从虚拟仿真技术的特征和安全评价教学现状出发,探究融合了虚拟仿真技术后的安全评价教学模式,从安全预评价,安全验收评价,安全现状评价三个阶段入手,建立一种基于虚拟仿真技术的安全评价教学模式,为改善安全评价教学效果提供有效的途径。

Abstract: Virtual reality technology is widely used in many fields because of its outstanding characteristics of immersion, multi-perception, autonomy and interactivity. In the field of education, virtual simulation technology makes two-dimensional knowledge and pictures three-dimensional, builds a self-perceived teaching model, improves the rigid education method, enhances the practical educational means, and greatly improves the teaching quality. In this paper, the teaching model is explored based on the characteristics of virtual reality technology and the present situation of safety evaluation teaching. A safety evaluation teaching system based on virtual reality technology is established from the perspective of safety pre-assessment, safety assessment upon completion and safety assessment in operation, which could provide effective way for the improvement of safety assessment teaching effect.
Keywords: safety assessment; virtual reality; teaching reform; blending means
一、概述
教學改革一直是改善教学效果,提高教学质量的有效方法,但是仅仅对教学内容进行增添或删减的教学改革,其效果往往是不尽如人意的。近年来随着电子科技的发展,越来越多的电子设备开始运用在教学过程中,使得原本枯燥乏味的教学过程变得生动形象,教学成果也明显得到了改善。王起全[1]等在安全工程教学过程中引入虚拟仿真技术,利用该技术,构建了可拆解、可运行的立体工艺系统,使得原本难以理解的机械结构与工作原理变得更加形象。涂然[2]等将虚拟仿真及仿真技术融入安全工程的教学中,利用Pathfinder、FDS等软件,对火灾安全事故进行了模拟教学,不仅培养了学生应对此类灾害的各项能力,也在很大程度上挖掘和拓展了学生的自我能动性。……
