A mock of the research question "Does AI help students increase learning achievement?" aligns with the topic "The Impact of AI Usage on College Students' Learning Achievement and Habit." Both focus on examining the effects of AI usage on learning achievement.

• The hypothesis, "The appropriate use of AI can positively impact college students' learning achievement." according to the information provided, the method could use group tests to compare the results. Such as dividing 1400 students into two groups; one group is a test group with the use of AI, and another is a group without the use of AI. Should we use a sample group?
• Should we choose the test content at a different difficulty level?
• Is a timely test needed or fit for the study?
• What challenges should consider during the experiment?
• What kind of data collected might not infer the test result? Or to avoid this kind of data?
• What ethical issues might appear during the study?
