Professor Hu Yi and his team at the School of Psychology and Cognitive Sciences of East China Normal University used brain hyperscanning technology based on functional near infrared photoimaging (fNIRS) to conduct in-depth studies on student preferences caused by teaching materials, the method of presenting materials by teachers, and brain synchronization between teachers and studentsEast China University released a number of new results of brain research At present, online education is the main form of teaching activities in primary and secondary schoolsWhat kind of online material does the students like? Why are some online materials more attractive to students? How should teachers present teaching materials? To do this, the team produced 12 videosThe video is a world-famous song played by the same violinistDuring the performance, the researchers used near-infrared instruments to record the brain activity of violinists (demonstrators) and record edited them, and then recorded the videos to students; After viewing the video, the researchers assessed how likely students liked the video material and calculated the indicator of brain-to-brain synchronization between students and demonstratorsThe recording of brain activity during video production and playback found that preference for video material was associated with synchronization between the left temporal lobe sitcom seamounts between student-demonstrators; These results show that a video material is popular with students because it is more likely to synchronize the student-demonstrator's brain; That is to say, good-looking video material, because many viewers and the demonstrators "do not fit" and "brain resonance." In addition to the brain region in which the brain syncscet occurs between students-demonstrators, and the correlation between the brain synchronization and the preference of video materials, the research team restored the interactive teaching scenario with high ecological validity, where teachers teach students knowledge face-to-face (in the field of psychology); In two kinds of teaching activities, the researchers also used near-infrared brain imaging technology, the whole process of simultaneous collection of teachers and students two people's brain activitiesIt was found that brain activity between teachers and students tended to synchronize in the teaching process, that is, when teachers adopted stent-based teaching, it was more synchronized with the students' brains than when they interpreted teaching, and this enhanced teacher-student brain synchronization could predict students' learning performance (Figure 3)In order to clarify the relationship between the brain synchronization of teachers and students and specific teaching behavior, the researchers used video coding technology to find that the enhancement of brain synchronization between teachers and students was related to the stent behavior adopted by teachers (such as asking guidance questions, providing innuendo, etc.); Based on these results, the research suggests that teachers in teaching activities, in addition to the necessary conceptual interpretation, can ask some easy to difficult questions to help students think about what they have learned and their relationship; Teaching strategy to regulate brain synchronization and brain-behavioral related team two papers published simultaneously in the internationally renowned neuroimaging journal Neuroimage, the first authors are PhD students Hou Yingying and Pan Yafeng (now a postdoctoral fellow of the Karolinska Institute in Sweden), which is the "psychology, education and brain science" interdisciplinary research results of the near-infrared ultrascanning research team of East China UniversityThe team will continue to expand the field of research (education, management, consulting, health, etc.) of near-infrared hyperscanning, and promote on-campus, off-campus and international cooperation at a more solid and higher level, and become a psychological science research center with the characteristics of "brain cognition" and leading the international academic frontier(BioValleyBioon.com)
