This study examines the current use of artificial intelligence in the learning activities of students at Hanoi Metropolitan University. The study employed a descriptive quantitative design using an online questionnaire on the Google Forms platform, comprising 12 items organised into three content groups concerning the level and frequency of use, the purposes of use, and perceptions of benefits and barriers. Data were collected from 240 students over a six-week period and were processed using descriptive statistics together with difference tests. The results indicate that all students in the sample used artificial intelligence in their learning to varying degrees, with ChatGPT being the most widely used tool and information searching and synthesis the purpose with the highest level of use. Students' perceptions of benefits and risks coexist, with a high level of concern about the risk of dependence and the reliability of information. The study identifies differences in use according to year of study and field of study.
