This paper presents the use of wearable psychophysiological sensors to monitor the physiological responses of students and teachers during educational activities. A multiparameter wearable sensing system, ResearchRing, was used to simultaneously acquire electrodermal activity, skin temperature, and heart rate. Emphasis is placed on the measurement system, signal acquisition and physiological signal processing. The paper introduces the concept of group physiological synchrony analysis as an objective metric for evaluating group dynamics during the learning process.
