Abstract
With the expansion of students' scale and the considerations for students' safety are increasing, the schools’ demand for virtual chemistry laboratories in chemistry teaching is increasing. Based on this background, combining with VIRTOOLS platform, PHOTOSHOP, 3D MAX and other software, this paper uses the computer simulation technology to develop a chemical virtual laboratory software. The virtual laboratory takes the experimental operation, experimental process explanation and monitoring, and experimental result feedback as the core functions, and it takes virtual roaming, external hardware and multimedia as assisted functions. The test results for the virtual laboratory show that the virtual laboratory has superior performance in experimental scene perception, experimental interaction, ease of use, and versatility, and is suitable for large-scale promotion. In addition, during the construction process of the virtual laboratory, this paper draws the following conclusions: selecting the scenario mode as the virtual laboratory construction mode can maximize the experimental scene perception and experimental interactivity; using software platform instead of a single software as main development technology can effectively improve the ease of use and the versatility of the virtual laboratory.
