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。

这是研究人员首次在安静、受控的实验室外,在如此大规模群体中同时利用这种技术,美国纽约大学神经学家Ido Davidesco说。近日他在美国科学促进会年会上通过海报形式展示了这一研究结果。

这样的结果一点儿也不奇怪,研究人员发现当学生注意力聚焦在同样的任务上时,大脑活动模式也会趋同。但是研究人员还发现,当一名学生更加聚精会神时,他的脑电波和群体的脑电波会更加匹配。与讲座和大声朗诵相比,那些学生更加喜欢的活动,如小组讨论和观看视频,会让他们的脑电波更加趋同。

Are your students bored? Check their brain waves

原文摘要:

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.
