Objective Molecular biology experimental technology has become an important basic tool for exploring biology and medicine and other related disciplines.We aim to explore an effective molecular biology experimental teaching model which will definitely improve students'molecular biology experimental skills and autonomous learning ability.Methods Guided by the theory of constructivism,with the molecular biology experimental course as the carrier,and with the basic requirements of constructing the basic molecular biology experimental technology of the system,a teaching platform was established to guide students to preview the experiment independently;the physical experimental projects were integrated and optimized and the virtual simulation experimental projects were increased,with virtuality and reality,to improve students'molecular biology experimental skills and autonomous learning ability.Results An online teaching platform has been established,which effectively guides and improves the effect of students'preview experiments,and cultivates the ability of autonomous learning.Besides,the experimental teaching mode combining optimization of physical experimental projects and virtual simulation experimental projects significantly improved students'molecular biology experimental operation skills and problem-solving ability.Conclusion A constructivism-based teaching mode of combining virtual and real molecular biology has been established,which is an effective way to improve students'molecular biology experimental skills and autonomous learning ability.
