| Outline of Final Research Achievements |
This study examined whether a student's level of attention to high-speeded educational videos could be assessed by event-related brain potentials (P300) . We recorded brain waves while participants viewing educational videos in two presentation speeds: original speed and double speed. As a result, the amplitude of P300 was smaller while participants were viewing videos at double speed than while viewing them at original speed. This finding suggests that, depending on the conditions, it may be possible that a level of attention to videos could increase by speeding up their presentation speed.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では，脳波データ（事象関連電位P300の振幅）を指標として，映像教材の高速視聴時における学習者の集中度合いを定量的に示すことを試みに成功した．このことによって，従来の方法に加え，生体情報をエビデンスとする映像教材に対する新たな評価方法が得られたといえる．今後は，本研究で得られた知見を基に，オンライン学習をはじめ，映像教材を活用した学習場面において，学習者の集中度合いに応じた適切な処遇を行える可能性がある．
