The most engaging educational videos are correlated with similar brain activity across learners, according to research in young adults recently published in eNeuro.
Yi Hu and colleagues at East China Normal University showed university students two-minute introduction clips for 15 online classes and monitored their brain activity via electroencephalogram. The students ranked the clips based on their desire to learn the material and then rated how interesting and valuable the class seemed.
The students displayed highly similar brain activity while they watched the clips that were universally ranked as the most appealing, while the lowest ranking videos correlated with the largest variety in brain activity. Additionally, the highest ranked videos were chosen because of their interest rather than their value.
