초록
The purpose of this study is to analyze the visual attention according to the career of teachers in elementary science lecture-centered class. The study participants were 4, and their career of education was 8 months, 4 years 1 month, 10 years 6 months, 13 years 4 months. A mobile eye-tracker was used to analyze the eye-movement of participants. The sampling rate of the mobile eye tracker was 60Hz and the participants wore the equipment during the lesson. The Begaze 3.7 program was used to analyze the eye movements of the participants. In this study, the actual education time, visual occupancy, average fixation time, average saccade velocity, and average pupil size were compared according to the class stage. The results of the study are as follows. First, as a result of analyzing the actual teaching time, it was found that the more teaching experience, the more the actual teaching time is secured. Second, in the area related to the teaching and learning activities by class stage, the higher the educational experience, the higher the visual attention of the student’s face. Third, there was a statistically significant difference between the average fixation time of each stage of class according to the educational experience. The more the education career, the less the change in the average fixation time of observation in the same educational activities. Fourth, the average saccade velocity by the stage of teaching was faster as the education career was more. Fifth, the mean pupil size of the participants in the instructional stage was the largest in the video materials regardless of the educational background, and the change in the mean pupil size in the same instruction activities was lower as the educational career was larger.
Abstract
The purpose of this study is to analyze the visual attention according to the career of teachers in elementary science lecture-centered class. The study participants were 4, and their career of education was 8 months, 4 years 1 month, 10 years 6 months, 13 years 4 months. A mobile eye-tracker was used to analyze the eye-movement of participants. The sampling rate of the mobile eye tracker was 60Hz and the participants wore the equipment during the lesson. The Begaze 3.7 program was used to analyze the eye movements of the participants. In this study, the actual education time, visual occupancy, average fixation time, average saccade velocity, and average pupil size were compared according to the class stage. The results of the study are as follows. First, as a result of analyzing the actual teaching time, it was found that the more teaching experience, the more the actual teaching time is secured. Second, in the area related to the teaching and learning activities by class stage, the higher the educational experience, the higher the visual attention of the student’s face. Third, there was a statistically significant difference between the average fixation time of each stage of class according to the educational experience. The more the education career, the less the change in the average fixation time of observation in the same educational activities. Fourth, the average saccade velocity by the stage of teaching was faster as the education career was more. Fifth, the mean pupil size of the participants in the instructional stage was the largest in the video materials regardless of the educational background, and the change in the mean pupil size in the same instruction activities was lower as the educational career was larger.
