Research Synthesizes 25 Years of Eye-Tracking Studies

A new narrative review published in Frontiers in Education synthesizes research from 1999 to 2025 on applying eye-tracking technology in educational settings for students ages 5 to 18 who experience learning differences including those related to reading, writing, and math. The review, conducted by researchers from the University of Cassino in Italy, examines how eye-tracking can serve both assessment and intervention purposes across academic domains including reading, writing, handwriting, spelling, and numeracy.

The research identifies consistent patterns in how students with handwriting differences visually process writing tasks. These patterns include slower and less stable gaze behavior, disrupted forward progression during writing, and increased cognitive load that shows up in eye-movement metrics. Most significantly, eye-tracking locates what researchers call “hidden breakdown points” in visuomotor coordination and phoneme-grapheme mapping—the connection between sounds and letters—that traditional accuracy measures miss entirely.
