基于物理算法的虚拟仿真实验教学理论与实验

Virtual Simulation Experimental Teaching Theory and Practice Based on Physical Algorithms

摘要: 随着元宇宙概念的兴起，虚拟仿真实验教学在教育领域的应用逐渐成为实验教学创新与改革的重要方向。基于物理算法的虚拟仿真实验教学是将元宇宙技术应用于教育领域的重要方式之一。然而，传统的理论教学与真实实验在演示材料微观结构演化方面存在直观性不足的问题，而现有的虚拟仿真实验则面临数据反馈不够精准、实验参数可调范围有限、难以有效关联材料微观结构与宏观性质等不足，这在一定程度上制约了学生微观思维和科学素养的培养。本研究遵循“教学与科研相结合”“虚拟与真实相促进”的原则，以物理算法为技术核心，以微观结构可视化为实现手段，开发出一套能够真实可靠地模拟微观结构演化过程、参数精确可调、结果精确可信、实验条件外推性强、可预测材料宏观性质的教学软件，并构建了与之相匹配的仿真教学理念。该教学方法能够有效加深学生对材料微观结构与宏观性质之间对应关系的理解，培养学生创造思维和理论科学素养，为探索基于物理算法的虚拟仿真实验教学实践与理论提供了新的思路和方法。

Abstract: With the rise of the metaverse concept, the application of virtual simulation experimental teaching in the education field has gradually become an important direction for the innovation and reform of experimental teaching. Virtual simulation experimental teaching based on physical algorithms is one of the important ways to apply metaverse technology in the education field. However, traditional theoretical teaching and real experiments have the problem of insufficient intuitiveness in demonstrating the evolution of material micro-structure. Existing virtual simulation experiments also have problems such as inaccurate data feedback, limited adjustable range of experimental parameters, and difficulty in effectively associating material micro-structure with macro-properties, which to some extent restricts the cultivation of micro-thinking and scientific literacy of students. This study follows the principles of “combining teaching and research” and “promoting the real by the virtual”, taking physical algorithms as the technical core and micro-structure visualization as the means of realization. It has developed a set of teaching software that can reliably simulate the micro-structure evolution process, with adjustable parameters, reliable results, strong experimental condition extrapolation, and the ability to predict material macro-properties. It has also constructed a simulation teaching concept that matches it. This teaching method can effectively deepen understanding of the correspondence between material micro-structure and macro-properties, cultivate creative thinking and theoretical scientific literacy, and provide new ideas and methods for exploring the practice and theory of virtual simulation experimental teaching based on physical algorithms.
