Do you still remember the experiment with sulfuric acid and nitric acid in junior high school chemistry class, when the rag developed many holes after being heated? In fact, a considerable number of chemical experiments are highly dangerous. In particular, the scale, level of detail, and amount of chemicals used in university experiments are very close to those in real situations, which accordingly increases the risks associated with these experiments. Even some safety experiments that allow hands-on participation are often constrained by hardware factors such as the location for the experiments, equipment, and funding, leaving students with few opportunities for practice. These issues result in low efficiency among students during practical experiments, as well as significant waste of time and materials; they represent problems that need to be addressed urgently in university experimental teaching. The chemical virtual experiment system developed by Qinhuangdao Yuandao Technology Development Co., Ltd. effectively solves the above problems. A chemical virtual experiment system creates a three-dimensional digital model of the laboratory environment, equipment, instruments, and reagents, thereby generating a realistic laboratory setting. Then, following the prescribed experimental steps, the students interactively operate the 3D instruments and experimental subjects to complete the entire experimental process. Finally, the system evaluates the students’ mastery of the experiment based on the completion status of the experiment and assigns a score for their performance. The virtual experiment system developed by Qinhuangdao Yuandao Technology Development Co., Ltd. is built using advanced international 3D graphics technology, and it boasts three key advantages that make it a leader among virtual simulation experiment systems in universities. With a high degree of realism, it enhances sensory understanding and deepens comprehension. The chemical virtual experiment system developed by Qinhuangdao Yuandao Technology Development Co., Ltd. closely simulates a real laboratory, creating a realistic experimental environment. In this environment, students can control instruments such as test tubes, droppers, beakers, and alcohol lamps, just as they would in a real laboratory, thereby gaining vivid and intuitive insights and improving their understanding of abstract chemical reactions. At the same time, chemical virtual experiment systems expand the variety of experimental equipment, offering more vivid formats and a greater diversity of experimental approaches. As an innovative form of learning, they help to stimulate students’ enthusiasm for independent learning and enhance their interest in studying. Combining interactive operations with assessments enhances teaching effectiveness. Qinhuangdao Yuandao Technology Development Co., Ltd. has developed a set of experimental training and assessment systems for this system that meet the requirements for evaluation. Students select the required experimental equipment and reagents on the virtual platform, add the reagents according to the experimental requirements and procedures, and carry out the experiment. After the virtual operation is completed, the student is given instructions regarding the incorrect actions taken, such as inaccurate dosage of the drug in step one, and so on. The system also retains a complete record of each step the student takes, and generates an experiment report at the end. Teachers can determine whether the experiment was successful and to what extent, based on the contents of the report. As one of the key features of virtual reality, interactivity serves as a major advantage for Qinhuangdao Yuandao Technology Development Co., Ltd. in applying this technology to virtual chemistry experiment teaching. It enables chemistry experiment teaching to move beyond theoretical discussions and enhances students’ practical skills. High security, protection from hazards, and reduced experimental costs. Chemical experiments involve handling various chemicals, which may have harmful properties such as irritating odors or corrosiveness; improper handling can lead to injuries to personnel and financial losses. Chemical virtual experiment systems can prevent various hazards associated with real experiments or mistakes, such as fires and explosions, allowing students to conduct experiments with confidence and thereby improving their knowledge and skills. On the other hand, in traditional teaching, preparing, storing, and managing the equipment and raw materials needed for experiments also requires long-term investment in human resources and resources. The chemical virtual experiment system powered by virtual reality technology allows experimental operations to overcome limitations such as equipment, materials, and location, providing students with the opportunity to conduct experiments at any time. Students can operate the equipment repeatedly to gain proficiency in these experiments, which not only ensures effective teaching outcomes but also significantly reduces costs.
