Eye-tracking technology has attracted researchers' attention for many years as a tool for finding objective data from cognitive processes. The present study, with the aim to investigate the applications of the mentioned technology in conducting research in the field of learning used systematic review method to analyze performed research from 2010- 2020. A total of 24 articles were analyzed after applying the inclusion and exclusion criteria. The results showed that among the eye tracker measurement scales, the researchers used eye fixation and duration of gaze in most learning studies. In addition, the results showed that studying visual attention during cognitive processing, examining the transition between textual and visual information, and comparing the strategies of successful reading, decision-making, problem solving and information processing modeling are the applications of eye movements in learning studies. According of the results, eye-tracking tool provides researchers with the opportunity to link learning outcomes to cognitive processes, which has implications for designing learning environments.
