Construction and Practical Exploration of Virtual Simulation Project in Biological Products Experimental Teaching
"Biological Products"is an important professional course in biotechnology,which involves a complex process and venue for the preparation of biological products. It is difficult for students to understand only through theoretical courses. This study designs the classic case of the course—"Preparation of viral vaccines"as a virtual simulation teaching experiment,allowing students to immerse themselves in a nearly real BSL-2 laboratory,completing the amplification,purification,titer detection,inactivation,and other steps of herpes sim-plex virus type Ⅱ. The assessment results and questionnaire surveys show that virtual simulation experimental teaching can improve stu-dents' mastery and application level of professional theoretical knowledge,while mobilizing students' enthusiasm and initiative in learn-ing,achieving good experimental teaching results.
