“…Various studies have added empirical support to theoretical claims about the positive effects of delivery of auditory media, visual media, or a combination of both, (Alwitt et al, 1980;Atkinson, et al, 2005;Calvert & Gersh, 1987;Calvert & Scott, 1989;Day et al, 2006;Kim et al, 2011;Luzón & Letón, 2015;Mann, 1979;Moreno & Mayer, 1999;Mautone & Mayer, 2001;Salomon, 1994;Sweller & Chandler, 1994;Wagley, 1978;van Gog et al, 2005;Zhang et al, 2006). Research is inconsistent in regards to the effect of multimedia delivery on germane load, with some studies claiming that it can actually have a negative effect on processing the learning materials, and ultimately germane load (Chandler & Sweller, 1991;Kizilcec et al, 2015;Mayer, 2014;Mayer & Moreno, 2003;Rasch & Schnotz, 2009;Schnotz & Rasch, 2005;Sweller, 1999;Sweller et al, 1998).…”
