Over the past few weeks, I have substantially revised my research proposal based on feedback from my supervisor and further literature review. I strengthened the methodology by redesigning the second stage as a one-year pilot quasi-experimental study with two comparison groups: students combining AI-assisted self-study with private tutoring and students relying solely on AI-assisted self-study with human mentorship. I also refined the participant selection criteria, expanded the sample size for the pilot study, improved the survey by aligning its questions with factors identified in previous studies, and incorporated demographic and moderating variables. These revisions have resulted in a more rigorous and methodologically sound research design. If you are interested to read all methodology, you can ask it.
