This study tried to know difference in concentration each school hours according to Zero Hour Class physical
activity through electroencephalogram(EEG) analysis. The study subjects were five female students at 5~6th
grade in elementary school. After Zero Hour Class physical activity, electroencephalogram(EEG) measurement
time was set thus the first time 9:10(examinee 1), 9:20(examinee 2), the second time 9:40(examinee 1),
9:50(examinee 2). And then, electroencephalogram(EEG) was measured for 120 seconds during which task for
concentration was given. Parts measured for electroencephalogram(EEG) were 6 areas(Fp1, Fp2, F3, F4, P3, P4).
Measured data were analyzed using SPSS 18.0 with ‘Wilcoxon signed rank test’ based on relative power value
of theta wave, alpha wave, beta wave, and gamma wave through power spectrum analysis. The results are as
follows. As a result of measuring the stable time vs the first time, theta wave showed significant difference
only on right frontal region(F4) and beta wave showed significant difference only on parietal region (P3, P4).
As a result of measuring the stable time vs the second time, theta wave showed significant difference on five
areas such as left prefrontal region(Fp1), frontal region(F3, F4), parietal region(P3, P4); beta wave on five areas
such as prefrontal region(Fp1, Fp2), left frontal region(F3), parietal region(P3, P4); gamma wave on two areas
such as prefrontal region(Fp1, Fp2). With the results, it could be identified that concentration was more
improved in the second time than the first time. Accordingly, it was found out that learning effect would be
higher when students have learning activity after regular break time after Zero Hour Class physical activity.
