[0002] Student experiments are a very important part of higher education. They can provide practical opportunities, improve students' thinking ability, and stimulate interest and innovation. At present, student experiments are mainly conducted offline. Although this is a traditional teaching method, it also has some shortcomings and disadvantages:

[0003] Offline laboratory resources are limited and cannot meet the needs of a large number of students. Students may need to wait in line and use limited instruments and equipment together, resulting in wasted experimental time. The laboratory space is limited and cannot accommodate a large number of students to conduct experiments at the same time. This may prevent students from participating in experiments in person, reducing students' practical opportunities. Offline laboratories usually have fixed opening hours or require advance reservations. Students need to conduct experiments at the prescribed time, which limits the efficiency of laboratory use. Such a time arrangement may not be flexible enough for students to conduct experiments according to their own learning progress and interests. Offline experiments require going to the laboratory or conducting experiments on site, which increases the user's transportation and time costs. The conduct of offline experiments requires various operations, including instrument connection, experimental preparation, and experimental process recording, which limits the efficiency of the experiment.
