“…Special attention was given to the non-verbal aspects of communication in the processes of meaning creation, including examining multimodal processes (Adami & Swanwick, 2019) of gestures and movements (Farsani, 2015a;Radford, Edwards, & Arzarello, 2009;Kress et al, 2001), posture (Brey & Shutts, 2015;Inagaki, Shimizu & Sakairi, 2018;Zahry & Besley, 2019), gaze (Araya, Farsani, & Hernández, 2016;Farsani & Villa-Ochoa, 2022;Holsanova, Rahm, & Holmqvist, 2006), nod (Smith-Hanen, 1977), and shoulder orientation (LaCrosse, 1975). However, few studies have focused on proxemics in classroom research (Collier, 1983), particularly in mathematics classes (Farsani, Breda, & Sala, 2020). Furthermore, few methodological tools have been developed to measure and evaluate students' visual engagement objectively.…”
