以衍射实验为例谈虚实结合实验教学模式

VIRTUAL-ACTUAL EXPERIMENTAL TEACHING MODE FOR DIFFRACTION EXPERIMENT

互联网、云计算、大数据等新网络信息技术不断更迭,催生了许多新的教学形态。作为一种新的教学形态,虚拟仿真实验依托虚拟现实、人机交互等信息化技术,在增强学生实践和科研能力、提高人才培养水平方面有着独特的优势。为发挥虚拟仿真实验的优势,我们构建一种结合成熟软件的适用于非物理类本科专业低年级的虚实结合实验教学模式,并以光学衍射实验为例,详细介绍这种模式的教学应用。实践表明,这种基于科学模型的可精确调节参数的定量仿真可有效提升传统实验教学的效率,拓展教学内容的广度和深度,提升实验教学的质量。

In the era of new network information technologies such as the internet,cloud computing,and big data,many new teaching forms have emerged.As a new teaching form,virtual simulation experiment relies on virtual reality,human-computer interaction and other information technology,which has unique advantages in enhancing students'abilities of practice and research,and improving the quality of developing talents.In order to take advantage of the virtual simulation experiment,we construct a teaching mode of virtual-actual combination experiment,which is suitable for the lower grades of non-physics majors.Taking the optical diffraction experiment as an example,we introduce the teaching application of this mode in detail.Teaching practice shows that the quantitative simulation based on the scientific model can effectively improve the efficiency of traditional experimental teaching,significantly expand the scope and depth of the knowledge of physics teaching,and improve the quality of experimental teaching.
