Research on the Design and Practice of Case-based Teaching Content Based on Virtual Reality Technology

In the higher education system, case-based teaching method can combine abstract theoretical knowledge with concrete practical cases, which makes up for many shortcomings of traditional teaching mode in cultivating students' practical ability, innovative thinking and ability to solve complex problems. However, there are still many problems in the current specific teaching practice, which seriously restricts the actual effect of case-based teaching method. In this regard, this paper will comprehensively analyze the implementation process of case-based teaching in colleges and universities, and propose a case-based teaching content design framework based on virtual reality technology, which provides new ideas and methods for solving the difficulties faced by traditional case-based teaching. Practice has proved that based on Unity3D virtual engine, the overall framework can combine three-dimensional modeling technology and dynamic visual interaction technology to construct rich and virtual case-based teaching scenes and teaching contents, give students an immersive and interactive teaching experience, and then break through the limitations of time and space to form a complete case-based teaching scheme.
