“…This is an important difference since prior research has shown that the user interface can have an impact on computer and web-based test scores (Bridgeman, Lennon, & Jackenthal, 2003;Huff, Cline, & Guynes, 2012;Květon, Jelínek, Vobořil, & Klimusová, 2007;Schroeders and Wilhelm, 2010;Wästlund et al's, 2008). More specifically to this research, very recent research have found differences in mean test scores between mobile devices and traditional computers (Arthur et al, 2014;Illingworth et al, 2014;Morelli et al, 2014;Sanchez & Branaghan, 2011;Sanchez & Goolsbee, 2010). However, the effect sizes of those differences have traditionally been small and very little is known as to why the differences exist at all.…”
