摘要 : 关注课堂注意力是否集中的老师有一天可以通过学生脑波之间的同步化程度找到答案。这是一项新研究的结论，该研究用头戴式耳机进行的脑电扫描法(EEG)，记录了12所高校的11节课中学生及老师的大脑神经活动。
Are your students bored? Check their brain waves
Teachers who wonder if their class is engaged could one day find out by checking how synchronized their brain waves are with each other. That’s the conclusion of a new study that logged the neural activity of 12 high school students and their teacher with electroencephalography (EEG) headsets over 11 classes. This is the first time the technology has been used simultaneously on such a large group outside of the quiet and controlled laboratory setting, says neuroscientist Ido Davidesco of New York University, who presented the study at a poster session yesterday at the annual meeting of AAAS (which publishes Science). Not surprisingly, patterns of brain activity were more similar when students were all focused on the same task. But the researchers also found that when a student reported being more engaged, thefrequency of their brain waves better matched the group. Activities the students liked more—group discussions and videos versus a lecture or being read to aloud—seemed to put them more in sync.
