## 4 Teaching Experiment
### System Satisfaction  
According to the results in Table 8, the overall average score of the satisfaction questionnaire for the VR360 ecological system is 4.38, indicating a level between \"very satisfied\" and \"satisfied\". Further analysis of each item reveals that the average scores of all items exceed 4. Specifically, the items receiving higher scores include the following: \"The learning approach enriches the learning experience\" (score = 4.50), \"The VR360 system provides useful information when needed\" (score = 4.56), and \"I quickly learned to use the VR360 system\" (score = 4.53). Regarding individual dimensions, the average score for the \"Usefulness\" dimension is 4.41, and the average score for the \"Ease of Use\" dimension is 4.34. This suggests that students were mostly satisfied with the VR360 ecological system, considering its usefulness and ease of use.
