“…In some studies, the pedagogical agents exhibited specific pointing gestures toward the task-related element on a graphic with their hand, eye gaze, and/or body rotation when the narration referred to it (Baylor & Kim, 2009; Johnson, Ozogul, Moreno, & Reisslein, 2013; Johnson, Ozogul, & Reisslein, 2015; Moreno, Reislein, & Ozogul, 2010; Twyford & Craig, 2013; Wang et al, 2018); in other studies, the pedagogical agents exhibited general gestures that guided learners to look in the direction of the presentation using their hand, eye gaze, and/or body rotation (Craig et al, 2002; Dunsworth & Atkinson, 2007; Lusk & Atkinson, 2007; Mayer & DaPra, 2012; Yung & Paas, 2015); in yet other studies, pedagogical engaged in casual NPGs without any specific visual guidance (Baylor & Ryu, 2003; Beege, Schneider, Nebel, & Rey, 2017; Shiban et al, 2015). Considering that different kinds of gestures may have different influence on learning (Gawne, Kelly, & Unger, 2009; Hostetter, 2011) and majority of previous studies are vague in the descriptions of the gestures displayed by pedagogical agents, it is worthwhile to disentangle the effects of different kinds of pedagogical agent gestures on instructional effectiveness in multimedia learning.…”
