Evaluation of Concentration Levels in Online Learning Using an Eye Tracker Device

Abstract

Online learning at universities has spread rapidly in response to the new Coronavirus infection. However, the major problem with online lectures is that it is very difficult to evaluate how concentrated the students are taking the lectures. Therefore, in this study, we propose a method to evaluate objectively the concentration level of students during online lectures using an eye tracking device. The concentration level is scored using eye movement data of the student viewing the online lecture slides and the total score is added up by computing some important parts of each slide. For the experiment, we made the contents for online lectures, the comprehension test to be conducted after online learning, and the questionnaire after the experiment. In this experiment, the correlation coefficient between the total score calculated by tracking the student’s line of sight for each slide and the score obtained from the confirmation test was calculated. As a result, it was shown that the higher the evaluation score of the concentration level, the score of the comprehension test arose, and the effectiveness of the proposed method for objectively evaluating the concentration level of the students was clarified.
