“…Considering the student perspective, several individual factors influencing the solution of word problems have been investigated apart from arithmetic skills (Daroczy et al, 2020;Verschaffel et al, 2020), including linguistic skills (Boonen et al, 2013;Boonen et al, 2016;Daroczy et al, 2015;Fuchs et al, 2006Fuchs et al, , 2018Pongsakdi et al, 2020;Swanson et al, 1993;Vilenius-Tuohimaa et al, 2008), spatial skills (Casey et al, 1997;Geary et al, 2000;Hegarty & Kozhevnikov, 1999;Resnick et al, 2020) and reasoning skills (Fuchs et al, 2015(Fuchs et al, , 2020Spencer et al, 2020;Vilenius-Tuohimaa et al, 2008). At the same time, Daroczy et al (2015) point out that few studies compared these factors in a comprehensive design that could reveal unique effects and interactions, and that these studies rarely considered task characteristics at the same time.…”
