Exploration of Virtual Simulation Teaching Mode of Landscape Design with OBE Concept as Core in Post-pandemic Era

Based on the background of the "online + offline" hybrid teaching of college environmental design courses in the post-epidemic era, the advantages and disadvantages of online teaching of college landscape design courses during the epidemic are analyzed to propose the OBE concept as the core of design education. The virtual simulation of teaching is introduced into the landscape design teaching curriculum. The design process of the virtual simulation teaching experiment is analyzed, including design tasks, on-site inspection, landscape analysis, epidemic prevention analysis, scheme discussion, plane planning. For this study, we took the online teaching practice of the "Virtual Simulation Experiment of Landscape Reconstruction of Sunlight Rock under the Background of Epidemic Normalization" as the research subject. There are ten links of function analysis, style positioning, effect display, and effect verification. In the aspects of virtual simulation experiment teaching method, the following is constructed: teaching content setting, digital information construction, school-enterprise cooperation mode, and teaching effect evaluation, and a virtual simulation teaching mode of college landscape design course oriented by learning output. The purpose is to improve students' autonomous learning by analyzing the ability to think and solve problems. To obtain better results and teaching effects, the paths and methods of teaching reform and innovation of landscape design courses in colleges and universities need to be explored.
