Shrnutí:In the past, most of virtual experiments usually no virtual tutor to help students, only provide a pure guided or open learning environment for the students, that prevents students from learning experiments efficiently. In this study, we proposed a semi-open learning strategy for the users to do experiments in the virtual environment with the help of the virtual tutor and exploratory guidance to learn making oxygen from potassium permanganate. The times of experimental errors, cost time of experiment and score of experimental knowledge were collected and compared between the group with the virtual tutor and exploratory guidance and the group without the virtual tutor and exploratory guidance. It is found that average times of experiment errors of the group with the virtual tutor and exploratory guidance was shortened by 0.83 times, the average time that users completed the experiment was shortened by 1 min. and 36 sec., and the average score of the experimental knowledge increased by 1.33 marks, compared to the group without the virtual tutor and exploratory guidance. It found that the virtual experiment environment of with the virtual tutor and exploratory guidance can effectively improve the efficiency of students' learning virtual experiment.
