이 연구는 0교시 체육활동에 따른 수업시간대별 집중력의 차이를 뇌파분석을 통해 알아보고자 하였다. 초등학교 5~6학년 여학생 5명을 대상으로 0교시 체육활동 후 1차 9시 10분(피험자 1), 9시 20분(피험자 2), 2차 9시 40분(피험자 1), 9시 50분(피험자 2)의 뇌파측정 시간을 설정하여 집중력 과제가 제시되는 120초 동안 뇌파를 측정하였다. 뇌파 측정부위는 6개의 영역(Fp1, Fp2, F3, F4, P3, P4)이었으며, 측정된 데이터는 파워스펙트럼분석(power spectrum analysis)을 통한 쎄타파, 알파파, 베타파, 감마파의 상대파워 값을 SPSS 18.0을 이용하여 Wilcoxon의 부호순위 검정을 실시한 결과 다음과 같은 결론을 얻었다. 안정시 vs 1차시 측정결과 쎄타파는 우측 전두부(F4), 베타파는 두정부(P3, P4)에서만 유의한 차이가 나타났다. 안정시 vs 2차시 측정결과 쎄타파는 좌측 전전두부(Fp1), 전두부(F3, F4), 두정부(P3, P4)의 5개 부위, 베타파는 전전두부(Fp1, Fp2), 좌측 전두부(F3), 두정부(P3, P4)의 5개 부위, 감마파는 전전두부(Fp1, Fp2)의 2개 부위에서 유의한 차이가 나타났다. 이러한 결과 1차시 보다 2차시에서 집중력이 더 향상되는 결과를 확인할 수 있었다. 따라서 0교시 체육활동 후 일정한 휴식을 거쳐 학습활동에 임할 때 보다 높은 학습효과를 거둘 수 있을 것으로 본다.
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.
