“…However, these studies are predominantly conducted in controlled laboratory settings, which may not fully capture the complexities of real-world classroom dynamics, thus limiting their ecological validity (Sonkusare et al, 2019;van Atteveldt et al, 2018). With the development of wearable electroencephalogram (EEG) and guided by the perspective of inter-brain coupling, recent hyperscanning studies have begun to move towards real-world classroom scenarios, primarily focus on inter-brain coupling among students (Chen, Qian, et al, 2023;Chen, Xu, et al, 2023;Davidesco et al, 2019;Dikker et al, 2017). The portability, ease of use, and low operational cost of wearable EEG devices are anticipated to facilitate the longitudinal recording of data in classroom settings, providing a rich, comprehensive description and analysis of learning processes.…”
