摘要：In recent years, virtual reality system (VRS) has become more prominent among many researchers due to its capacity of providing as close as possible to real-life experience for users from diverse fields of life, such as tourism, academics, manufacturing and medicine. In this study, we present an VRS for the titration experiment in a chemistry laboratory to enable students to learn the titration experiment in a virtual laboratory environment before proceeding to the chemistry wet lab. The virtual chemistry laboratory environment was developed using the Unity Real-Time Development Platform, and the Microsoft SQL Server was used for the database to enable easy assessment of the student performance after the experiment. To evaluate our VRS, we tested it among 50 students (25 high school and 25 first-year undergraduate chemistry students). We collate their user’s experience through a structured questionnaire, and the responses from the students show that 60% agreed that it was helpful, 66% easy to interact with and 54% strongly agreed that it improved learning. Therefore, it is evidence that the proposed VR-enabled chemistry laboratory platform could be used to improve the understanding of chemistry titration practical process among students.
