Electron microscope is a large optical instrument with ultra-high resolution using electromagnetic lens for imaging. However, it is difficult to carry out in the teaching of understanding experimental courses as well as practical training, due to a number of factors, such as its precise structure, high cost of operation and maintenance, lack of experimental resources, high teaching cost, its internal structure is not easy to observe, the long experimental time, et al. In order to solve these problems, the virtual simulation experiment project of electron microscope ultra-thin section technology and negative staining technology was developed based on its imaging principle. This project also incorporates the latest scientific researches and technical application cases as well as the new generation information technology in the process of designing teaching objectives, constructing corresponding knowledge system, establishing comprehensive evaluation system to track learning effect of students throughout the whole process. Teaching practice of the combination of virtual and real teaching effectively expands students’ learning space and knowledge system, enriches the content and means of experimental teaching and practical training, forms student-centered independent learning teaching resources, significantly improves the experimental teaching effect. This project is obviously conducive to the cultivation of innovative and outstanding talents in basic disciplines.
