Abstract



Human body-language is one of the richest and most obscure sources of information in inter-personal communication. In this paper we present our observations of student-to-student influence and measurements. We show parallels with previous theories and formulate a new concept for measuring the level of attention based on synchronization of student actions. We observed that the students with lower levels of attention are slower to react than focused students, a phenomenon we named “sleepers' lag”. This realization may give rise to novel measurements that can act as a technological support for teacher's meta-cognition. The end goal is to improve the teacher-student conversation and to enable a shorter feedback loop of teacher's performance compared to the current-day methods.
