The purpose of this study was to examine the effect of a peer assessment during physical education by measuring and analyzing the characteristic of the brain functions through the electroencephalogram(EEG). The sixth grade elementary school students were (n=24) participated in the EEG measurement after a physical education including a peer assessment. The EEG was recorded from eight scalp locations(Fp1, Fp2, F3, F4, P3, P4, O1, O2) with a linked ears reference during resting eye closed, watching best performance and a peer assessment activity. Independent Component analysis(ICA) was carried out for the obtained EEG data, and then calculated theta, alpha, and beta relative power spectrum and correlation coefficient between electrodes. The EEG data measured and analyzed was implemented the matched pair t-test. As a result of relative power spectrum, the mean value of the theta waves' activation in a peer assessment showed higher than that of watching the best performance. And there was a significant difference at F3. The mean value of the alpha waves' activation in watching the best performance showed higher than that of a peer assessment. There was a significant difference at P3, P4, and O1. The mean value of the beta waves' activation in a peer assessment showed higher than that of watching the best performance. And there was a significant difference at Fp1. As a result of relative power spectrum of left and right brain, the mean value of theta waves' activation showed a dominance at left frontal, F3. The mean value of the alpha waves' activation showed a dominance at right frontal pole Fp2 and right occipital O2. The mean value of the beta waves' activation did not show a significant difference between left and right brains. As a result of correlation analysis between electrodes, the mean value of correlation in a peer assessment showed lower than that of watching the best performance. And there was a significant difference at P3-P4, P3-O2, and P4-O2.
