This research examines how multilingual college students use AI writing tools and whether these tools support or hinder learning. The findings suggest that learning outcomes depend on how AI is used. When employed as a scaffold for feedback and reflection rather than a shortcut, AI can enhance writing development and critical thinking.

This neuroscience study shows that brief pre-lecture interactions significantly improve learning. Students who chatted with either a human teacher or an AI tutor before watching a video lecture performed better and showed greater brain synchrony in MRI scans. Social interaction—human or artificial—primes the brain for more effective learning.

This research explores how over 500 international students use AI tools like ChatGPT while navigating university study in a second or third language. Findings reveal AI can reduce overwhelm and support learning, but also risk undermining confidence and skill development. The study guides universities toward better language support, policy, and pedagogy.
