“…Simulation was evaluated in two (8%) of the studies (Ayres, Langone, Boon, & Norman, 2006; Hansen & Morgan, 2008). Two (8%) studies looked at calculator use (Root, Saunders, et al, 2017; Yakubova & Bouck, 2014), one (4%) evaluated the use of a math game to teach number identification (Everhart, Alber-Morgan, & Park, 2011), one (4%) utilized single-switch voice output devices (Hudson, Zambone, & Brickhouse, 2016), and one (4%) measured generalization from a worksheet to an iDevice (Root, Saunders, et al, 2017).…”
